Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Verified OEM automotive data for vehicles 1982-2013. Returns part numbers, torque specs, fluid capacities, and service procedures sourced directly from factory service manuals. Built for AI agents: pass year/make/model plus a natural-language query. Data is authoritative (from OEM manuals), not generated.

charm_lookup

Advertised by the server during the last successful anonymous check.

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")

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http charm-mcp https://mcp.chatwithcharm.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add charm-mcp --url https://mcp.chatwithcharm.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable charm-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "charm-mcp": {
      "url": "https://mcp.chatwithcharm.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "charm-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.chatwithcharm.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start charm-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "charm-mcp": {
      "type": "http",
      "url": "https://mcp.chatwithcharm.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http charm-mcp https://mcp.chatwithcharm.com/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Claude Desktop configuration

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "charm-mcp": {
      "serverUrl": "https://mcp.chatwithcharm.com/mcp"
    }
