Brave Search MCP Server

An MCP server implementation that integrates the Brave Search API, providing comprehensive search capabilities including web search, local business search, place search, image search, video search, news search, LLM context, and AI-powered summarization. This project supports both STDIO and HTTP transports, with STDIO as the default mode.

Migration

1.x to 2.x

#### Default transport now STDIO

To follow established MCP conventions, the server now defaults to STDIO. If you would like to continue using HTTP, you will need to set the BRAVE_MCP_TRANSPORT environment variable to http, or provide the runtime argument --transport http when launching the server.

#### Response structure of brave_image_search

Version 1.x of the MCP server would return base64-encoded image data along with image URLs. This dramatically slowed down the response, as well as consumed unnecessarily context in the session. Version 2.x removes the base64-encoded data, and returns a response object that more closely reflects the original Brave Search API response. The updated output schema is defined in src/tools/images/schemas/output.ts.
