Publish, delete and read your own posts (toots) on any Mastodon instance via the Mastodon REST API. Use when the user wants to post a toot to their Mastodon / fediverse account, cross-post an article as a short dev-focused post, delete a toot, or list their own recent posts with engagement stats (boosts, favourites, replies).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Call the **Mastodon REST API** with `curl + jq`. Two connector credentials are
injected: `$MASTODON_BASE_URL` (the instance, e.g. `https://mastodon.social`)
and `$MASTODON_ACCESS_TOKEN`. Every request sends the header
`Authorization: Bearer $MASTODON_ACCESS_TOKEN`.
Errors come back as JSON `{"error":"<message>"}` — show it verbatim. `401`
(`"The access token is invalid"`) means the token is wrong/revoked → the user
must re-connect the Mastodon connector. Posting needs the token to have the
`write` (or `write:statuses`) scope.
**Always confirm the token + account first** (also gives the account `id` you
need to list your own toots):
```bash
curl -sS "$MASTODON_BASE_URL/api/v1/accounts/verify_credentials" \
-H "Authorization: Bearer $MASTODON_ACCESS_TOKEN" \
| jq '{id, username, acct, display_name, followers: .followers_count, statuses: .statuses_count}'
```
## Post a toot
**Confirm with the user before posting publicly.** Default `visibility` to
`unlisted` unless they say post publicly; use `public` only on request.
```bash
STATUS_TEXT="Hello fediverse 👋 #introductions"
curl -sS -X POST "$MASTODON_BASE_URL/api/v1/statuses" \

How to install
mdr add acedatacloud/skills/mastodon@sha256:2e068084f9f267a8The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
