Airlock MCP Server

Run five agents on one repo without them stomping on each other. Named resource locks, atomic shared state, presence, events, and a task queue for AI agents - exposed over a local HTTP MCP server that's always running, so any session, terminal, or CI job can coordinate with any other. Cross-platform Go daemon, SQLite-backed, with real blocking waits - no more poll loops. Its 8 documented tools cover lock, resource, note.

People who work with lock, resource and note and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Go.
