Dictionary Server is a Model Context Protocol (MCP) server that retrieves word meanings, pronunciation, definitions, and example sentences from the Cambridge Dictionary. It is designed for developers building AI assistants (like Claude) or any MCP‑compatible tool that needs dictionary lookup capabilities.

After configuration, run the server with npm run start:mcp. You can also test it using the MCP Inspector via npm run inspector.
