What the code does

We read the source, 20 h ago · rules 3dff92dd89df

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Claims read-only, but the code runs commands redos-measure.cjs:44
    const child = spawn(process.execPath, ['-e', CHILD_SRC, String(n), PATTERN], {
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.

Runs an external command redos-measure.cjs:44
    const child = spawn(process.execPath, ['-e', CHILD_SRC, String(n), PATTERN], {
Builds a file path from a variable validate-server-json.cjs:154
  must(fs.existsSync(path.join(__dirname, bin)), `bin target ${bin} not found`);

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

We found things in this code

Code changes quietly between releases, and nobody reads the diff of a dependency. We do, on every release — watch Agent Core and you get told the day something new turns up.

Agent Core — questions

Answers built from our own checks of this server.

Why is there no uptime for Agent Core?
Agent Core 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 agent-core-mcp was installed 341 times last week.
How do I connect Agent Core?
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 agent-core-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Agent Core?
The npm package agent-core-mcp was installed 341 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Agent Core open source?
Yes — it is published under the MIT licence, written in JavaScript and 0 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.
