Agent Core runs on your own machine — the client starts it, so there is no endpoint to ping. 43 installs a week from npm. Last commit 11 Sep 2026.
Deterministic computation tools for AI agents. Zero dependencies, no network, read-only.

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.

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.
const child = spawn(process.execPath, ['-e', CHILD_SRC, String(n), PATTERN], {
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.
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.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
