MCP serverAI & models

Catch fake packages and exposed secrets in AI-written code before they cause problems. This app checks what your AI coding assistant produces, flagging packages that don't actually exist and passwords or keys left in the code. It covers 6 package ecosystems and needs no account.

Available today. Use it from your connected AI after setup.

Add it to your AI coding setup and run a check on your project before code goes further. No account is needed.

Then ask your AI: use graneth-mcp to scan repository

What your AI can do with it

  • Flag packages your AI invented that don't actually exist
  • Spot passwords and API keys accidentally left in code
  • Check packages across 6 ecosystems
  • Screen AI-written code before it moves forward
  • Run checks without creating an account

Source for @graneth/mcp-server — an account-free MCP server that checks AI-written changes before they are committed: packages that do not exist, dependency risk shapes, and hardcoded secrets.

What is in this repository

packages/mcp-serverthe MCP server itself — stdio, hand-rolled JSON-RPC, no runtime dependencies
packages/core-checksthe detection core it bundles: registry existence across six ecosystems, manifest parsing, secret patterns + entropy, risk scoring

What is not

The hosted scanning service is a separate, closed codebase: pull-request scanning, the second-pass LLM triage, policy enforcement, signed receipts and billing are not here and are not open source. This repository is the free tool and the checks it runs — which is the part you install on your machine, and therefore the part worth being able to read.

How it is maintained

Generated from the internal monorepo, which is the source of truth. Edits made directly here are overwritten on the next sync, so please open an issue rather than a patch — the fix lands upstream and comes back with the next release.

Three of core-checks' test files are held back: they assert that the secret rules fire, so their fixtures are literal example credentials, and every scanner — GitHub's push protection and this project's own — reads them as the real thing. The rules themselves are here in full (packages/core-checks/src/secrets.ts), as are the package's other tests.
