How we built the Redis Docs MCP for agents | Redis

This post details the development of Redis Docs MCP, a public MCP server for accessing Redis documentation. It covers the MCP tool surface (`search`, `fetch`, `ask`), the rationale behind a keyless, public server, and the architecture involving a single writer and two readers for the docs index. The implementation uses RedisVL for direct index querying by `search` and `fetch`, while `ask` leverages Context Retriever and a language model. The post also discusses design review processes and the importance of stable identifiers for agent retrieval.
