Overview
What is MDN Lookup?
MDN Lookup is an MCP-compatible tool server that lets you query MDN documentation using natural language or API/method names, returning concise summaries and direct links. It is designed for developers who want instant access to MDN reference material directly from their editor.
How to use MDN Lookup?
Install the package and configure your MCP client (e.g., VS Code) to point to the index.js entry point. The server runs over stdio, so no additional runtime configuration is required; it uses the public MDN API out of the box.

FAQ from MDN Lookup
What makes MDN Lookup different from a web search or a browser bookmark?
It provides instant, query‑focused results directly inside your editor or MCP client, with a summary link, rather than requiring a browser tab and manual navigation.
Does MDN Lookup require any API key or registration?
No. The server uses the public MDN API with no additional configuration or authentication needed.
What runtime or dependencies does MDN Lookup need?
No extra runtime beyond a standard Node.js environment. The server runs as a stdio process and is ready to plug into any MCP client.
Does MDN Lookup cache or store any data?
The README does not mention caching or local storage; it references the public MDN API, so data is fetched live on each query.
What transport does MDN Lookup use?
It uses stdio transport, making it compatible with any MCP client that supports subprocess‑based tool servers.
