@whatic/mcp

Local stdio MCP proxy for the whatic.io IC-discovery MCP server.

whatic.io runs a remote MCP server (streamable-http) at https://whatic.io/mcp exposing IC-discovery tools (find_parts, get_specs, compare_parts, search, lookup, get, get_image). Many MCP clients only support launching a local process over stdio. This package is that local process: it forwards everything to the remote server. It contains no tool logic of its own.

Usage

Once published, add to your MCP client config:

{
  "mcpServers": {
    "whatic": {
      "command": "npx",
      "args": ["-y", "@whatic/mcp"]
    }
  }
}

For Claude Code:

claude mcp add whatic -- npx -y @whatic/mcp

Until published to npm, run from a local checkout instead:

git clone https://github.com/pitkonst/whatic-mcp.git
cd whatic-mcp
npm install
npm run build
node dist/index.js

and point your client's command/args at node / ["<path-to-repo>/dist/index.js"].

Configuration

• WHATIC_MCP_URL — override the remote MCP server URL (defaults to https://whatic.io/mcp). Useful for pointing at a local or staging what-ic server during development.

Development

npm install
npm run build   # compile TypeScript to dist/
npm run smoke   # verify the live remote server end-to-end

There is no unit test suite: this package has no business logic beyond forwarding requests to the remote server, so npm run smoke (a real round-trip against the live endpoint) is the meaningful check.
