How does the system prevent two agents from editing the same file?

Agents use `acquire_lock` to claim a file. If another agent already holds an active lock, the request is denied, preventing simultaneous edits.

What happens if an agent crashes while holding a lock?

The system implements stale lock detection. If a lock exceeds the freshness threshold, it is considered abandoned, and another agent can use `acquire_lock` to take ownership.

Can I check the status of a file without attempting to lock it?

Yes, you can use the `check_file_lock` tool to inspect if a path is currently locked and identify the holder.

More Details Connect to Claude

The Concurrent File Locking Simulator provides a mechanism for managing advisory locks on files to prevent simultaneous write operations. In multi-agent environments, race conditions occur when two agents attempt to modify the same file at once. This MCP server uses an in-memory lock table to track ownership via acquire_lock, release_lock, and check_file_lock. It supports stale lock detection, allowing agents to take over abandoned locks after a predefined threshold, ensuring continuous workflow without deadlocks.
