Lightweight MCP server for multi-session awareness — lets AI agents know who else is active on the same machine.

## Why

When you run multiple AI CLI sessions (Kiro, Claude Code, Gemini CLI) on the same machine, they are blind to each other. This causes:

- **File conflicts** — two sessions editing the same file
- **Duplicated work** — agents picking up the same task
- **Wasted context** — no way to know what another session is doing

**mcp-session-registry** solves this with a shared presence layer:

- Sessions register on spawn, declare a theme, and heartbeat every 2-3 minutes
- Sessions claim files/resources — other sessions see the claim before touching them
- Stale sessions (no heartbeat >5min) are automatically reaped
- Everything persists in SQLite — survives individual session crashes

## Quick Start

```bash
# Run directly
uvx mcp-session-registry

# Or install
pip install mcp-session-registry

# Configure port (default: 8000)
MSR_PORT=3203 mcp-session-registry
```

## MCP Tools

| Tool | Description |
|------|-------------|
| `session_register` | Register a new session. Returns `session_id` for subsequent calls. |
| `session_list` | List all active sessions on this machine. |
| `session_heartbeat` | Send heartbeat to keep session alive (call every 2-3 min). |
| `session_end` | Gracefully end a session and release all its claims. |
| `session_claim` | Claim a resource (file, branch, work item). Advisory lock. |
| `session_release` | Release a previously claimed resource. |
| `session_conflicts` | Check if resources are claimed by another active session. |
