Use Casii MCP in WorkBuddy

Add Casii MCP by pasting one JSON config under WorkBuddy's Custom connector, then click Connect and approve in your browser — no API key needed.

Prerequisites

  1. WorkBuddy installed and signed in.
  2. A Casii account. On the first connection a Casii authorization page opens in your browser — sign in and approve; no API key to create or copy. You can disconnect anytime under Connected apps in the dashboard.

If saving fails, check that the JSON is complete (brackets, commas and quotes all in pairs).

Verify it works

Ask directly in WorkBuddy, e.g.:

Use casii MCP’s detect_export_target to check how many followers the nasa account has on Instagram

The first call asks for tool permission; after that the AI handles detection, quoting and creation automatically. Creating and resuming must carry a stable idempotency key (idempotency_key, UUID format) generated once: retrying with the same key and the same parameters returns the original tasks and never charges twice; only changed parameters make it a new operation with a new key.
