Agent Search Engine

Issue 001 / A living technical almanac

Rankings never sold

The shortlist

Give your agent live docs & search

Models train on a snapshot; your dependencies don't stop moving. Two MCP servers fix the two halves of this — current library docs, and real web search — and a third lets you self-host the search side entirely.

3 picks · chosen editorially from the index · how we choose

Library docs

Config entry in your MCP client

context7MCP server

59k stars · Open source · TypeScript

Feeds MCP clients current, version-correct library documentation — the highest-adopted docs server in the index, and the difference between the agent guessing an API and reading it.

Watch outYour stack is niche enough that its docs are not covered.

Web search

Config entry + API key

exa-mcp-serverMCP server

4.7k stars · Open source · TypeScript

Search built for AI consumption, exposed over MCP — one config entry gives your agent a real search tool instead of stale training data.

Self-hosted search

Self-host — Docker

mcp-searxngMCP server

1.0k stars · Open source · TypeScript

MCP bridge to SearXNG, the self-hosted meta-search engine — web search for your agent with no third-party API and no query logs leaving your infrastructure.

Before you commit

Every retrieval tool you add widens what the agent reads — and web content is untrusted input. Prefer read-only search/docs servers, and treat 'the agent found it online' with the same skepticism you'd give any unverified source.
