Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

charm
charm_list_makes
List all vehicle manufacturers covered by CHARM (1982-2013). Use to check coverage before a lookup.
charm_lookup
Look up verified OEM part numbers, torque specs, fluid capacities, and service procedures for vehicles 1982-2013. Returns structured data sourced directly from factory service manuals (not model-generated). Provide year+make+model when known for a precise, isolated answer. Args: query: What you want to know (e.g. "front brake caliper part number", "spark plug gap", "engine oil capacity") year: 4-digit year, 1982-2013 make: Manufacturer (e.g. "Ford", "Honda", "Chevy Truck") model: Model name (e.g. "Taurus X", "Civic", "Silverado") system: Optional system filter (e.g. "brakes", "engine", "electrical")

Charm — questions

Answers built from our own checks of this server.

What can Charm do?
It exposes 2 tools, read directly from the server on our last check. Among them: charm_list_makes, charm_lookup. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Charm working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 2 of 91 checks got a reply (2.2%), average response time 598 ms. The bar chart above shows every period we have measured.
How do I connect Charm?
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 is a remote server, so there is nothing to install — the client connects to the address.
Does Charm need an API key?
No. Charm completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Charm?
It answers our handshake in 598 ms on average, which is faster than 16% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Charm open source?
Yes — it is published under the MIT licence, written in Python 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.
