+# MCP Agent Mail Integration - Current Status
+
+## Completed
+- ✅ **bd-muls**: MCP Agent Mail server installed and tested locally
+  - Server running successfully on port 8765
+  - Web UI accessible at http://127.0.0.1:8765/mail
+  - Installation location: `mcp_agent_mail/`
+
+## Known Issues
+- ⚠️ MCP API tool execution errors when calling `ensure_project`
+  - Core HTTP infrastructure works
+  - Web UI functional  
+  - Needs debugging of tool wrapper layer
+
+## Next Ready Work
+- **bd-6hji** (P0): Test exclusive file reservations with two agents
+  - Requires working MCP API (fix tool execution first)
+
+## Quick Start Commands
+```bash
+# Start server
+cd mcp_agent_mail && source .venv/bin/activate && uv run python -m mcp_agent_mail.cli serve-http
+
+# Access web UI
+open http://127.0.0.1:8765/mail
+
+# Stop server
+pkill -f "mcp_agent_mail.cli"
+```
