No longer in the registry. The MCP registry stopped listing this server as of 20 Oct 2026. This page stays available because the measurement was real, but the server is excluded from search, rankings, and Vouch’s corpus counts. A published behaviour score is never recomputed or removed — it reflects what was measured while the server was listed.

Not yet verified. Verifying proves you control this server and is free, permanently — it never changes a published score.

Tools

receive_file
Use this when you have been given an 83blue transfer link and need the file. Accepts a capability url (https://upload.83blue.com/f/...) on its own, or a share url plus password. Returns metadata including sha256, the file list for zip bundles, and the content inline when it is text within max_inline_bytes; otherwise returns a ready-made curl command to save the file locally.
shallow
share_conversation
Use this to hand your full working context to another AI: any provider, any model, any chat client. Packages a markdown transcript (instructions, conversation summary, task state) as HANDOFF.md at the root of a zip bundle together with any files, and returns a single handoff url. The receiving model just fetches that url: it gets a briefing, the file manifest and download commands in one go. Say to the next agent: "Fetch this url to pick up where I left off."
shallow
share_file
Use this when another AI agent (a different machine, model or chat session) or a person needs access to one or more files. Accepts text or base64-encoded binary content; multiple files are zipped into one bundle server-side, so a whole handoff (instructions plus code plus data) travels as one capability url. For large files already on local disk, prefer the HTTP API (one curl command, up to 1 TB): https://upload.83blue.com/docs
shallow
share_text
Use this when another AI agent, chat session or person needs text you have: instructions, code, JSON, a prompt for another model. Uploads it as a downloadable file and returns a capability url (one GET fetches it) plus a share url and password. No account or API key needed.
