Overview
RAE MCP Server is an MCP implementation that connects language models to the Royal Spanish Academy (RAE) API, enabling LLMs to query RAE's dictionary and linguistic resources through standardized tools. The project is implemented in Go and requires Go 1.21+. Install by cloning the repository at https://github.com/rae-api-com/rae-mpc.git and running go build in the rae-mpc directory. The server supports multiple transport options for LLM integration: stdio transport for in-process usage, and an SSE HTTP server (e.g., on port 8080). The MCP exposes tools such as 'search' (takes a required query and an optional lang, default es) and 'get_word_info' (takes a required word and an optional lang, default es). This setup allows language models to access lexical data to improve Spanish language capabilities, dictionary lookups, and lexical reasoning via MCP.
Features
stdio transport
Run the MCP server with stdio transport for seamless in-process integration with LLMs.
SSE transport
Operate as an SSE server exposing MCP endpoints over HTTP on a configurable port (e.g., 8080).
MCP tool: search
Expose the search tool to query the RAE API with a required query and optional language (default es).
MCP tool: get_word_info
Expose the get_word_info tool to fetch detailed information for a word, with optional language (default es).
Go-based implementation
Implemented in Go 1.21+ with a straightforward build process: clone, then go build.
