Agent Coherence — Stale Write Guard (FS): MCP server

What Agent Coherence — Stale Write Guard (FS) does

According to its repository: “Coherence guard for shared files: when two agents write the same file, the stale writer is denied instead of overwriting, then reacquires and retries.”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Agent Coherence — Stale Write Guard (FS) is listed under Files and documents, a category of 55 servers in the directory, where it ranks #42 by stars.

Topics declared by the repository: state-synchronization, token-efficiency, agent-memory, ai-agent, cache-coherence, llm-agent.

Installing and connecting Agent Coherence — Stale Write Guard (FS)

Distribution modes declared in the official MCP registry:

• PyPI package (Python, started with uvx or pip)

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: Python.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

Points found for Agent Coherence — Stale Write Guard (FS):

• System access: the Files and documents category gives the agent control over files, a terminal, code or a browser. A booby-trapped instruction in content the agent reads (prompt injection) can then turn into an action.
• No licence: without a licence the code is not legally reusable, even if it is public. Avoid it in a company setting without the author's agreement.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on March 4, 2026, the cohexa-ai/agent-coherence repository has 11 stars and 3 forks, with 87 open issues. It has more stars than 28% of the servers in the directory. It received changes this month. Version published in the registry: 0.14.1 (September 5, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
