What Mastodon World (BYOK) is for

Mastodon World (BYOK) lets an AI assistant read your own Mastodon World data through the Mastodon World API with a key you supply (access token). Read-only: 12 tools (verify_credentials, get_account, lookup_account, list_account_posts, public_timeline, hashtag_timeline, home_timeline, trending_tags, trending_posts, search_accounts, search_posts, list_notifications). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to mastodon.world. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Mastodon World. Mastodon World and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "Which mastodon.world account is my token connected to?"
• "How many followers does mastodon.world account 1 have?"
• "What is the account ID of Gargron on mastodon.world?"
• "What has mastodon.world account 1 posted recently?"
• "What is being posted publicly on mastodon.world right now?"
• "Show recent posts tagged #opensource on mastodon.world"

What it does

• verify_credentials: Show the mastodon.world account the token belongs to: handle, display name, bio, follower and post counts.
• get_account: Get one account's public profile by its ID: handle, bio, bot flag, follower, following and post counts, last post date.
• lookup_account: Find an account by handle (for example 'Gargron' for a local user) and return its ID and profile counts.
• list_account_posts: List an account's posts, newest first, with text (HTML), date, counts and tags. Can skip replies and boosts.
• public_timeline: List recent public posts on mastodon.world (local and federated), newest first, optionally only local, remote or with media.
• hashtag_timeline: List recent public posts that use one hashtag, newest first.
• home_timeline: List the latest posts from the accounts you follow, newest first (needs the read:statuses scope).
• trending_tags: List hashtags that were used more than usual over the past week, with daily use and account counts.
• trending_posts: List posts that are getting more interaction than others right now, with counts and author.
• search_accounts: Search accounts on mastodon.world by name or handle and return matching profiles.
• search_posts: Full-text search of posts on mastodon.world (needs a token; results depend on the server's search setup).
• list_notifications: List your notifications (mentions, boosts, favourites, follows) newest first (needs the read:notifications scope).

BYOK key

You bring your own Mastodon World access token (https://mastodon.world/settings/applications). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to mastodon.world over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Mastodon World (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Mastodon World (BYOK) is. Mastodon World (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Mastodon World data: Read timelines, profiles, hashtags, trends, notifications and search on mastodon.world (general-interest server) with your own access token. You bring your own Mastodon World access token; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Mastodon World call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to mastodon.world, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Mastodon World rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Mastodon World receives. The request we make on your behalf, including the key and the arguments, under Mastodon World's own terms and privacy policy. Mastodon World acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Mastodon World gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Mastodon World data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Mastodon World (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Mastodon World at any time to end all access.

Children. Mastodon World (BYOK) is a general-audience service operated by the adult using the assistant, under Mastodon World's own age rules.

Changes. We will post changes here with a new effective date.
