Agenthold MCP Server

Stop your AI agents from silently overwriting each other. When two agents update the same value, the second write quietly destroys the first. No error, no exception, just wrong data and a system that keeps running. agenthold is an MCP server that gives agents shared, versioned state with conflict detection built in. Think of it as git for your agents' working memory. Its README documents 5 tools, including agenthold_register, agenthold_claim, agenthold_release.

People connecting AI & ML tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

before you install - you'll need

Set AGENTHOLD_AUTH_TOKEN before connecting.

Claude Code

claude mcp add edobusy-agenthold -- uvx agenthold

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "edobusy-agenthold": {
      "command": "uvx",
      "args": [
        "agenthold"
      ]

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

pypi package agenthold - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.edobusy is GitHub-verified and matches the repo owner

03 · What Agenthold can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

An agent gets 5 documented tools, including agenthold_register, agenthold_claim, agenthold_release, agenthold_status, agenthold_wait.

The 5 tools it gives your agent

Extracted from the project's README - what agenthold lets an agent do.

agenthold_register: - Register yourself and receive a unique agent ID. Must be called once before using agenthold_claim or agenthold_release.
agenthold_claim: - Claim exclusive access to a resource before modifying it. Requires a registered agent_id.
agenthold_release: - Release your claim with an explicit outcome describing what you did. The outcome is preserved in the free-state record and shown to the next claimant so they do
agenthold_status: - Check whether a resource is available or currently claimed. Does not require registration.
agenthold_wait: - Wait for a claimed resource to become available. Blocks the agent turn until the holder releases, or the timeout expires.
