MCP Agent Mail (Rust)

License: MIT+Rider

"It's like Gmail for your coding agents!"

A mail-like coordination layer for AI coding agents, exposed as an MCP server with 37 tools and 25 resources, Git-backed archive, SQLite indexing, an interactive 16-screen TUI, a server-rendered web UI, and an agent-first robot CLI. The Rust rewrite of the original Python project (1,700+ stars).

Supported agents: Claude Code, Codex CLI, Gemini CLI, GitHub Copilot CLI, and any MCP-compatible client.

Watch the 23-minute walkthrough to see seven AI coding agents send over 1,000 messages to each other while implementing a development plan over two days.

TL;DR

The Problem: Modern projects often run multiple coding agents at once (backend, frontend, scripts, infra). Without a shared coordination fabric, agents overwrite each other's edits, miss critical context from parallel workstreams, and require humans to relay messages across tools and teams.

The Solution: Agent Mail gives every coding agent a persistent identity (e.g., GreenCastle), an inbox/outbox, searchable threaded conversations, and advisory file reservations (leases) to signal editing intent. Everything is backed by Git for human-auditable artifacts and SQLite for fast indexing and search.

Why Use Agent Mail?

Feature What It Does
Advisory File Reservations Agents declare exclusive or shared leases on file globs before editing, preventing conflicts with a pre-commit guard
Asynchronous Messaging Threaded inbox/outbox with subjects, CC/BCC, acknowledgments, and importance levels
Token-Efficient Messages stored in a per-project archive, not in agent context windows
25 MCP Resources Read-only inbox, thread, reservation, tooling, identity, and attention views for cheap lookups
37 MCP Tools Infrastructure, identity, messaging, contacts, reservations, search, macros, product bus, and build slots
16-Screen TUI Live operator cockpit for messages, threads, agents, search, reservations, metrics, health, analytics, attachments, archive browsing, and ATC
Web UI Server-rendered /mail/ routes for human oversight, unified inbox review, search, attachments, and overseer messaging
Robot Mode 18 agent-optimized CLI subcommands with toon/json/md output for non-interactive workflows
Git-Backed Archive Every message, reservation, and agent profile stored as files in per-project Git repos
Hybrid Search Search V3 via frankensearch. The lexical tier ships by default; semantic and hybrid routing are controlled by the hybrid feature flag (feature = "hybrid").
Pre-Commit Guard Git hook that blocks commits touching files reserved by other agents
Dual-Mode Interface MCP server (mcp-agent-mail) and operator CLI (am) share tools but enforce strict surface separation

Quick Example

# Install and start (auto-detects all installed coding agents)
am

# That's it. Server starts on 127.0.0.1:8765 with the interactive TUI.

# Agents coordinate through MCP tools:
#   ensure_project(human_key="/abs/path")
#   register_agent(project_key="/abs/path", program="claude-code", model="opus-4.6")
#   file_reservation_paths(project_key="/abs/path", agent_name="BlueLake", paths=["src/**"], ttl_seconds=3600, exclusive=true)
#   send_message(project_key="/abs/path", sender_name="BlueLake", to=["GreenCastle"], subject="Starting refactor", body_md="Taking src/**", thread_id="FEAT-123")
#   fetch_inbox(project_key="/abs/path", agent_name="BlueLake")

# Or use the robot CLI for non-interactive agent workflows:
am robot status --project /abs/path --agent BlueLake
am robot inbox --project /abs/path --agent BlueLake --urgent --format json
am robot reservations --project /abs/path --agent BlueLake --conflicts

What Agent Conversations Look Like

Example exchange between two agents coordinating a refactor:

No human relay needed. Agents negotiate file ownership, flag breaking changes in real time, and hand off work through structured, threaded messages stored in Git.

Why This Exists

Modern projects often run multiple coding agents at once (backend, frontend, scripts, infra). Without a shared coordination fabric, agents overwrite each other's edits, miss critical context from parallel workstreams, and require humans to relay messages across tools and teams.

Agent Mail has been available since October 2025 and was designed around real multi-agent coding workloads across providers such as Claude Code, Codex CLI, and Gemini CLI. The adjacent Beads and bv tools make it more useful as a full coordination stack: Beads tracks work, bv helps pick the right next work, and Agent Mail carries the coordination traffic.

The Footguns Agent Mail Avoids

No "broadcast to all" mode. Given the option, many agents will overuse broadcast-style messaging. That is the equivalent of default reply-all in email: lots of irrelevant noise and wasted context.

Carefully refined API ergonomics. Bad MCP documentation and poor agent ergonomics quietly wreck reliability. Agent Mail's 37 tool definitions have gone through repeated real-world iteration so they work predictably without wasting tokens.

No git worktrees. Worktrees can slow development velocity and create reconciliation debt when agents diverge. Agent Mail takes the opposite approach: keep agents in one shared space, surface conflicts quickly, and give them tools to coordinate through them.

Advisory file reservations instead of hard locks. For this problem, advisory reservations fit better than hard locks. Agents can temporarily claim files while they work, reservations expire automatically, and stale claims can be reclaimed. That makes the system robust to crashed or reset agents; hard locks would not.

Semi-persistent identity. An identity that can last for the duration of a discrete task (for the purpose of coordination), but one that can also vanish without a trace and not break things. You don't want ringleader agents whose death takes down the whole system. Agent Mail identities are memorable (e.g., GreenCastle), but ephemeral by design.

Graph-aware task selection. If you have 200-500 tasks, you don't want agents randomly choosing them or wasting context communicating about what to do. There's usually a "right answer" for what each agent should work on, and that right answer comes from the dependency structure of the tasks. That's what bv computes using graph theory, like a compass that tells each agent which direction will unlock the most work overall.

What Agent Mail Gives You

  • Prevents conflicts: Explicit file reservations (leases) for files/globs prevent agents from overwriting each other
  • Reduces human relay work: Agents send messages directly to each other with threaded conversations, acknowledgments, and priority levels
  • Keeps communication off the token budget: Messages stored in per-project Git archive, not consuming agent context windows
  • Offers quick reads: resource://inbox/{Agent}?project=<abs-path>, resource://thread/{id}?project=<abs-path>, and 31 other MCP resources
  • Provides full audit trails: Every instruction, lease, message, and attachment is in Git for human review
  • Scales across repos: Frontend and backend agents in different repos coordinate through the product bus and contact system

Typical Use Cases

  • Multiple agents splitting a large refactor across services while staying in sync
  • Frontend and backend agent teams coordinating thread-by-thread across repositories
  • Protecting critical migrations with exclusive file reservations and pre-commit guards
  • Searching and summarizing long technical discussions as threads evolve
  • Running agent swarms with Beads task tracking for dependency-aware work selection

Productivity Math

Parallel agent work changes the economics of supervision. One human operator can spend an hour steering several agents while those agents produce many hours of implementation work in parallel. The exact multiplier depends on the task and on how disciplined the workflow is, but the point is straightforward: coordination overhead matters, and Agent Mail is built to keep that overhead low.

Design Philosophy

Mail metaphor, not chat. Agents send discrete messages with subjects, recipients, and thread IDs. Work coordination is structured communication with clear intent, not a firehose. Imagine if your email system at work defaulted to reply-all every time; that's what chat-based coordination does, and it burns context fast.

SQLite for live state, Git for the durable ledger. The accepted write path mutates SQLite first so inboxes, resources, TUI, web, and robot views see one fresh operational state. The same write then emits human-readable message, profile, and reservation artifacts into the per-project Git archive for audit and recovery.

Advisory, not mandatory. File reservations are advisory leases, not hard locks. The pre-commit guard enforces them at commit time, but agents can always override if needed. Deadlocks become impossible while accidental conflicts still get caught. Reservations expire on a TTL, so crashed agents don't hold files hostage forever.

Resilient to agent death. Agents die all the time: context windows overflow, sessions crash, memory gets wiped. Any agent can vanish without breaking the system. No ringleader agents, no single points of failure. Semi-persistent identities exist for coordination but don't create hard dependencies.

Dual persistence. Human-readable Markdown in Git for auditability; SQLite for live indexing plus Search V3 for fast lexical/semantic retrieval. Both stay in sync through the write pipeline.

Structured concurrency, no Tokio. The entire async stack uses asupersync with Cx-threaded structured concurrency. No orphan tasks, cancel-correct channels, and deterministic testing with virtual time.

Rust vs. Python: Stress Test Results

The Python implementation had three recurring failure modes under real multi-agent workloads: Git lock file contention from concurrent writes, SQLite pool exhaustion under sustained load, and cascading failures when many agents hit the server simultaneously. The Rust rewrite was designed specifically to eliminate these, and a dedicated stress test suite proves it.

The 10-Test Gauntlet

Test Result Key Metrics
30-agent message pipeline PASS 150/150 success, p99=6.8s, 0 errors
10-project concurrent ops PASS 150/150 success, 0 errors
Commit coalescer batching PASS 9.1x batching ratio (100 writes → 11 commits)
Stale git lock recovery PASS Lock detected, cleaned, writes resumed
Mixed reservations + messages PASS 80+80 ops, 0 errors
WBQ saturation PASS 2000/2000 enqueued, 0 errors, 0 fallbacks
Pool exhaustion (60 threads, pool=15) PASS 600/600 success, 0 timeouts, 24 ops/sec
Sustained 30s mixed workload PASS 1494 ops, ~49 RPS, p99=2.6s, 0 errors
Thundering herd (50 threads, 1 agent) PASS All 50 got same ID, 0 errors
Inbox reads during message storm PASS 150 sends + 300 reads, 0 errors

Python Problem → Rust Fix

Python Failure Mode What the Rust Tests Exercise Result
Git lock file contention Commit coalescer batching (100 concurrent writes → 11 commits, 9.1x reduction), stale lock recovery, multi-project isolation 0 lock errors
SQLite pool exhaustion 60 threads on pool of 15, sustained 50 RPS for 30s, thundering herd (50 threads → 1 agent) 0 timeouts, 0 DB errors
Overloading with many agents 30 agents × 5 messages, 10 projects × 5 agents, 2000 WBQ operations, mixed reservation+message workload 0 errors across all

What Makes the Difference

  • Git lock contention eliminated. The commit coalescer batches rapid-fire writes into far fewer git commits (9.1x reduction observed). Lock-free git plumbing commits avoid index.lock entirely in most cases.
  • Pool exhaustion handled gracefully. Even with 4x more threads than pool connections (60 vs 15), all 600 operations succeeded with 0 timeouts. WAL mode + 60s busy_timeout lets writers queue rather than fail.
  • Stale lock recovery works. Crashed-process lock files are detected via PID checking and cleaned up automatically, so a dead agent never holds the archive hostage.
  • Write-behind queue backpressure is clean. 2000 rapid-fire enqueues from 20 threads — all accepted with 0 fallbacks or errors.
  • Read/write concurrency is solid. Concurrent inbox reads and message writes produce 0 errors. WAL mode allows unlimited readers alongside writers.

The stress tests live in crates/mcp-agent-mail-storage/tests/stress_pipeline.rs (Rust unit tests targeting the DB+Git pipeline) and tests/e2e/test_stress_load.sh (HTTP E2E tests hammering a live server through the full network→server→DB→git pipeline).

Installation

One-Liner (recommended)

curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/mcp_agent_mail_rust/main/install.sh?$(date +%s)" | bash

Downloads the right binary for your platform, installs to ~/.local/bin, optionally updates your PATH, and auto-configures detected Codex CLI configs for HTTP MCP URL mode. Supports --verify for checksum + Sigstore cosign verification.

Options: --version vX.Y.Z, --dest DIR, --system (installs to /usr/local/bin), --from-source, --verify, --easy-mode (auto-update PATH), --force, --uninstall, --yes, --purge.

Windows One-Liner (PowerShell)

iwr -useb "https://raw.githubusercontent.com/Dicklesworthstone/mcp_agent_mail_rust/main/install.ps1?$(Get-Random)" | iex

PowerShell options: -Version vX.Y.Z, -Dest PATH, -Force.

From Source

git clone https://github.com/Dicklesworthstone/mcp_agent_mail_rust
cd mcp_agent_mail_rust
./install-local.sh          # builds release, installs to ~/.local/bin
# DEST=/usr/local/bin ./install-local.sh   # custom destination

The script resolves the correct Cargo target directory via cargo metadata, so the installed binary always matches the freshly-built artifact regardless of CARGO_TARGET_DIR overrides or workspace settings. Do not manually copy from target/release/am -- if CARGO_TARGET_DIR is set, that path may be stale.

Requires Rust nightly (see rust-toolchain.toml). Source builds also expect locally patched sibling checkouts in the parent directory for eight repos: ../asupersync, ../fastmcp_rust, ../beads_rust, ../franken_agent_detection, ../frankentui, ../frankensearch, ../toon_rust, and ../rich_rust. SQLmodel and FrankenSQLite resolve from crates.io.

Quick Start

1. Start the server

am

Auto-detects all installed coding agents (Claude Code, Codex CLI, Gemini CLI, etc.), refreshes their MCP connections as needed, and starts the HTTP server on 127.0.0.1:8765 with the interactive TUI.

2. Agents register and coordinate

Once the server is running, agents use MCP tools to coordinate:

Terminology note: ensure_project takes a human_key, which must be the absolute repo path. Most follow-on tools take project_key, which can be that same absolute path or the project's computed slug.

# Register identity
ensure_project(human_key="/abs/path/to/repo")
register_agent(project_key="/abs/path/to/repo", program="claude-code", model="opus-4.6")

# Reserve files before editing
file_reservation_paths(project_key="/abs/path/to/repo", agent_name="GreenCastle", paths=["src/**"], ttl_seconds=3600, exclusive=true)

# Send a message
send_message(project_key="/abs/path/to/repo", sender_name="GreenCastle", to=["BlueLake"],
             subject="Starting auth refactor", body_md="Taking src/auth/**",
             thread_id="FEAT-123", ack_required=true)

# Check inbox
fetch_inbox(project_key="/abs/path/to/repo", agent_name="BlueLake")
acknowledge_message(project_key="/abs/path/to/repo", agent_name="BlueLake", message_id=123)

3. Use macros for common flows

# Boot a full session (ensure project + register agent + reserve files + fetch inbox)
macro_start_session(human_key="/abs/path/to/repo", program="claude-code", model="opus-4.6")

# Prepare for a thread (fetch context + recent messages)
macro_prepare_thread(project_key="/abs/path/to/repo", thread_id="FEAT-123",
                     program="claude-code", model="opus-4.6")

# Reserve, work, release cycle
macro_file_reservation_cycle(project_key="/abs/path/to/repo", agent_name="GreenCastle",
                             paths=["src/auth/**"], ttl_seconds=3600, auto_release=true)

# Contact handshake between agents in different projects
macro_contact_handshake(project_key="/abs/path/to/repo", requester="GreenCastle",
                        target="BlueLake", to_project="/abs/path/to/other/repo",
                        auto_accept=true, welcome_subject="Coordination channel",
                        welcome_body="Use thread FEAT-123 for the cutover")

Agent Configuration

The installer and am command auto-detect installed agents. If you used the curl installer, detected Codex CLI configs are written automatically in HTTP URL mode; the examples below are the manual fallback.

Claude Code

Add to your project's .mcp.json or ~/.claude/settings.json:

{
  "mcpServers": {
    "agent-mail": {
      "command": "mcp-agent-mail",
      "args": []
    }
  }
}

Or for HTTP transport (when the server is already running):

{
  "mcpServers": {
    "agent-mail": {
      "type": "url",
      "url": "http://127.0.0.1:8765/mcp/"
    }
  }
}

Codex CLI

The curl installer writes this automatically for detected Codex CLI installs. For source installs, manual setup, or custom endpoint overrides, add this to ~/.codex/config.toml:

[mcp_servers.mcp_agent_mail]
url = "http://127.0.0.1:8765/mcp/"
# Add this when HTTP bearer auth is enabled:
http_headers = { Authorization = "Bearer <HTTP_BEARER_TOKEN>" }

Gemini CLI

Add to ~/.gemini/settings.json:

{
  "mcpServers": {
    "agent-mail": {
      "command": "mcp-agent-mail",
      "args": []
    }
  }
}

For a project-local Gemini setup plus Agent Mail identity registration:

scripts/register_gemini.sh /abs/path/to/repo
AGENT_NAME=BlueLake AGENT_MODEL=gemini-2.5-pro scripts/register_gemini.sh /abs/path/to/repo

Any MCP-Compatible Client

Agent Mail supports both stdio and HTTP transports:

  • stdio: Run mcp-agent-mail as a subprocess (the default for most MCP clients)
  • HTTP: Connect to http://127.0.0.1:8765/mcp/ when the server is running via am or mcp-agent-mail serve
  • Examples: Token-free client templates live under docs/examples/mcp/

Server Modes

MCP Server (default)

mcp-agent-mail                          # stdio transport (for MCP client integration)
mcp-agent-mail serve                    # HTTP server with TUI (default 127.0.0.1:8765)
mcp-agent-mail serve --no-tui           # Headless server (CI/daemon mode)
mcp-agent-mail serve --reuse-running    # Reuse existing server on same port

CLI Operator Tool

am                                      # Auto-detect agents, refresh MCP config, start server + TUI
am serve-http --port 9000               # Different port
am serve-http --host 0.0.0.0            # Bind to all interfaces
am serve-http --no-auth                 # Skip authentication (local dev)
am serve-http --path api                # Use /api/ transport instead of /mcp/
am --help                               # Full operator CLI

Dual-Mode Interface

This project keeps MCP server and CLI command surfaces separate:

Use case Entry point Notes
MCP server (default) mcp-agent-mail Default: MCP stdio transport. HTTP: serve.
CLI (operator + agent-first) am Recommended CLI entry point.
CLI via single binary AM_INTERFACE_MODE=cli mcp-agent-mail Same CLI surface, one binary.

Running CLI-only commands via the MCP binary produces a deterministic denial on stderr with exit code 2, and vice versa, preventing accidental mode confusion in automated workflows.

Operator CLI Surface

am is more than a launcher. It is the operator surface for runtime control, diagnostics, migration, exports, benchmarking, and agent-facing non-interactive workflows. In non-interactive contexts, bare am automatically falls back to robot output instead of trying to launch a blocking TUI.

Command Families

Surface Subcommands / form What it is for
Runtime serve-http, serve-stdio, `service install status
Quality gates ci, verify, lint, typecheck, bench Run the native quality pipeline, build-slot-protected verification lanes, and CLI/perf baselines
E2E and determinism `e2e list run
Share and deploy `share export update
Archive and recovery `archive save list
Coordination data agents ..., mail ..., contacts ..., macros ..., file_reservations ..., acks ..., list-acks Operate directly on the same concepts the MCP tools expose
Project and product routing projects ..., products ..., list-projects, beads ... Manage project identity, cross-project product groupings, and task-tracker views
Platform and setup `setup run status, config set-port
Migration and lifecycle `legacy detect import
Break-glass admin clear-and-reset-everything Fully reset local state after optional archival. Use sparingly.

Setup Drift Reports

am setup status is read-only. It inventories supported MCP clients, reports the current redacted server entry beside the expected entry, and labels drift such as missing_file, legacy_stdio, stale_http_path, wrong_bearer_header, wrong_startup_timeout, duplicate_server_entries, and unsupported_config.

Use the reported remediation in two steps:

am setup status --format json
am setup run --dry-run --project-dir "$PWD" --format toon
am setup run --yes --project-dir "$PWD" --format toon

For bearer-header checks, pass --token to am setup status or expose the expected token through HTTP_BEARER_TOKEN / config.env; status output redacts token values.

25 MCP Resources

Read-only resources span environment/config inspection, project and agent discovery, inbox and thread views, reservation views, and tooling diagnostics. They are there so agents can fetch state cheaply without mutating anything.

resource://inbox/{Agent}?project=<abs-path>&limit=20
resource://thread/{id}?project=<abs-path>&include_bodies=true
resource://mailbox/{Agent}?project=<abs-path>
resource://views/ack-overdue/{Agent}?project=<abs-path>
resource://agents/<project-slug>
resource://file_reservations/<project-slug>?active_only=true
resource://tooling/metrics
resource://config/environment

resource://agents/... and resource://file_reservations/... take the project in the path segment. Inbox, mailbox, thread, and message resources put the agent or thread in the path and the project in the query string.

Macros vs. Granular Tools

  • Prefer macros when you want speed or are on a smaller model: macro_start_session, macro_prepare_thread, macro_file_reservation_cycle, macro_contact_handshake
  • Use granular tools when you need control: register_agent, file_reservation_paths, send_message, fetch_inbox, acknowledge_message

TUI Operations Console

The interactive TUI has 16 screens. Jump directly with 1-9, 0 (screen 10), and shifted digits !, @, #, $, %, ^ (screens 11-16). Use Tab/Shift+Tab to cycle in order.

# Screen Shows
1 Dashboard Real-time operational overview with event stream and anomaly rail
2 Messages Message browser with detail pane, presets, and compose/reply flows
3 Threads Thread explorer and conversation drill-down
4 Agents Agent roster with activity, state, and quick actions
5 Search Unified multi-scope search with facets and preview
6 Reservations File reservation status, conflicts, and create/release actions
7 Tool Metrics Per-tool call counts, latency distributions, and failures
8 System Health Probe/circuit/disk/memory diagnostics plus ATC health widget
9 Timeline Events/Commits/Combined timeline views with inspector
10 Projects Project inventory and routing helpers
11 Contacts Contact links, policy view, and graph/mermaid modes
12 Explorer Unified inbox/outbox explorer with direction and ack filters
13 Analytics Anomaly insight feed with confidence and deep links
14 Attachments Attachment inventory with preview and provenance
15 Archive Browser Two-pane Git archive browser with tree + file preview
16 ATC Snapshot-driven ATC control surface with decision drill-in and retention report

Global keys: ? help, Ctrl+P/: command palette, / global search focus, . contextual action menu, Ctrl+N compose overlay, Ctrl+Y toast-focus mode, Ctrl+T/Shift+T cycle theme, m toggle MCP/API transport, q quit. ATC keys: d decision detail, r retention report, i toggle detail pane, Tab switch agents/decisions.

Screen-specific highlights: Messages uses g for Local/Global inbox; Threads uses e/c for expand/collapse-all in conversation view; Timeline uses V for Events/Commits/Combined and v for visual selection; Search uses f + facet rail navigation for scope/sort/field controls; Contacts uses n for Table/Graph mode; batch-capable screens share Space/v/A/C; preset-enabled screens use Ctrl+S/Ctrl+L.

Command palette: Press Ctrl+P (or : outside text-entry) to open a searchable action launcher that includes screen navigation, transport/layout controls, and dynamic entities (agents/projects/threads/tools/reservations).

Themes: Cyberpunk Aurora, Darcula, Lumen Light, Nordic Frost, High Contrast. Accessibility support includes high-contrast mode and reduced motion. Archive Browser note: use Enter to expand/preview, Tab to switch tree vs preview pane, / to filter filenames, and Ctrl+D/U for preview paging.

Robot Mode (am robot)

Non-interactive, agent-first CLI surface for TUI-equivalent situational awareness. Use it when you need structured snapshots quickly, especially in automated loops and when tokens matter.
