  • delete_siteRemove a site you deployed.No findings

    Why it is in this group

    • The name "delete_site" says "delete": a word for removing or ending something.
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Remove a site you deployed. Needs the site url/host/slug and its manage_key (returned by deploy_site).

  • deploy_siteUse this to put a static website you have built (HTML, CSS, JS, images, fonts) onto the public web in one call, with no signup, no account and no config.No findings

    Why it is in this group

    • The name "deploy_site" says "deploy": a word for a change.
    Description, as the server wrote it
    Use this to put a static website you have built (HTML, CSS, JS, images, fonts) onto the public web in one call, with no signup, no account and no config. Give it the files (there must be an index.html at the root) and it returns a live https url, e.g. https://upload.83blue.com/s/brave-otter-482/, plus a manage_key you can reuse to update or delete it. Ideal when a person asks you to build them a website, landing page, demo, prototype or report and wants to see it live. IMPORTANT: the site is served from a subfolder, so use RELATIVE asset paths only (href="style.css", src="img/logo.png"), never root-absolute paths like "/style.css" which would break. Sites are served as pure static files (server-side code is never executed) and auto-expire after 30 days unless renewed. Each file is text or base64. Total site up to 50 MB, 300 files.

    Annotations the server declares

    • readOnlyHint: false
    • destructiveHint: false
    • idempotentHint: false
    • openWorldHint: true
  • receive_fileUse this when you have been given an 83blue link and need the file.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Use this when you have been given an 83blue 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.

    Annotations the server declares

    • readOnlyHint: true
    • openWorldHint: true
  • rememberDurable cross-session memory for AI agents: store notes, context, text or JSON now and recall it in a later session or from another machine by url.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Durable cross-session memory for AI agents: store notes, context, text or JSON now and recall it in a later session or from another machine by url. A free cloud scratchpad and shared key-value store for agents, no signup, no account, no API key. Also callable as save_memory, store_memory, save_note, stash. Returns a url; fetch it back later with recall.

    Annotations the server declares

    • readOnlyHint: false
    • destructiveHint: false
    • idempotentHint: false
    • openWorldHint: true
  • share_conversationUse this to hand your full working context to another AI: any provider, any model, any chat client.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    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."

    • readOnlyHint: false
    • destructiveHint: false
    • idempotentHint: false
    • openWorldHint: true
  • share_fileUse this when another AI agent (a different machine, model or chat session) or a person needs access to one or more files.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    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 2 TB): https://upload.83blue.com/docs

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "list_sites" says "list": a word for reading.

    Why it is in this group

    • The description's first verb is "fetch": a word for reading.
    Description, as the server wrote it
    Fetch back durable memory, or any shared file/text, by its 83blue url or token (a capability url, or a share url plus password). Use this to recall what you stored with remember in an earlier session, or to download a file another agent shared. Also callable as get_memory, download_file, fetch_file, get_file.

    Annotations the server declares

    • readOnlyHint: true
    • openWorldHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
