Quick Install

Automated & IDE Setup

Copy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.

One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.

Manual Client & Custom JSON ConfigExpand JSON ▾

No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for rae-api-com/rae-mcp, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.

Documentation Overview

RAE Model Context Protocol (MCP) Server

This repository contains an implementation of a Model Context Protocol (MCP) server for the Royal Spanish Academy (RAE) API. It allows language models to interact with RAE's dictionary and linguistic resources.

Requirements

Go 1.21+

Installation

bash

git clone https://github.com/rae-api-com/rae-mpc.git
cd rae-mpc
go build

Usage

Command Line Arguments

Run the server with stdio transport (for integration with LLMs):

bash

./rae-mpc --transport stdio

Or run it as an SSE server:

bash

./rae-mpc --transport sse --port 8080

Available Tools

The MCP server exposes the following tools to LLMs:

search - Search RAE API for information
- Parameters:
  - query (required): The search query
  - lang (optional): Language code (default: "es")
get_word_info - Get detailed information about a word
- Parameters:
  - word (required): The word to look up
  - lang (optional): Language code (default: "es")

Integration with LLMs

This MCP server can be integrated with language models that support the Model Context Protocol, allowing them to access RAE's linguistic resources for improved Spanish language capabilities.
