xkcdai MCP
An MCP server that builds a semantic index over every xkcd comic using on-device embeddings and exposes a find_xkcd tool. It allows agents to search for relevant comics based on title, mouseover text, and transcripts, with a relevance threshold to ensure quality matches.
Endpoint and access
No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

find_xkcd
Find xkcd comics semantically relevant to the current conversation. Call this whenever an xkcd comic might enrich the conversation — when the discussion lands on a topic xkcd is famous for skewering (programming, science, statistics, relationships, the absurdity of standards, etc.). Pass a concise description of the current topic or theme as `context` (a phrase or sentence works better than a whole transcript), e.g. "spending hours automating a task that was faster to do by hand" or "code finally compiling". IMPORTANT — deciding whether to mention one. xkcd has a comic for almost every topic, so this tool will nearly always return something. A result being returned does NOT mean you should bring it up. Use the `score` as a signal and apply your own judgment about conversational fit: score >= 0.75 strong match — usually worth mentioning if it fits the moment 0.66 - 0.75 plausible — mention only if it genuinely lands < 0.66 weak/tangential — almost always better to stay silent Only one comic, at most, per topic — and only when it actually adds something. When you do share one, cite it by number and title with its `url`, and quote the `alt` (mouseover) text — it's half the joke. Returns a dict with a `results` list (num, title, score, url, image, alt, explain_url) and a `count`. An empty list means nothing cleared the floor.
