FreeFree verified knowledge base that coding agents query via MCP
What is AgentsKB?
AgentsKB is a free knowledge service that gives AI agents verified answers about APIs, SDKs and frameworks instead of guesses from training data. It holds tens of thousands of researched answers across more than 240 technologies, each linked to official documentation.
Instant mode returns pre-researched answers in about 40 milliseconds and says explicitly when it has no answer. Research mode handles topics not yet covered by researching official sources on the spot, and each new answer is then stored for everyone.
Agents connect with one line of MCP configuration in Claude Code, Cursor or Cline, or by calling the REST API from any language. Batch queries handle up to 250 questions at once, and there is no signup, API key or monthly cap, only a rate limit of 20 requests per second.
