What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Builds a file path from a variable src/bridge/client.ts:233
    const cmdPath = path.join(this.inboxDir,  cmdFilename);

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Agentbridge — questions

Answers built from our own checks of this server.

Why is there no uptime for Agentbridge?
Agentbridge runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package classic-mac-mcp was installed 32 times last week.
How do I connect Agentbridge?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls classic-mac-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Agentbridge?
The npm package classic-mac-mcp was installed 32 times in the last week. Week over week that is +22%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Agentbridge open source?
Yes — it is published under the GPL-3.0 licence, written in C and 24 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
