Sponsors fund a Tab to keep running. An operator runs it — on their own assistant, on their own subscription — and TabTab verifies each run and pays for reliability. This page is the work, step by step.
Payouts are monthly, for reliability rather than for volume: a month at or above the spec's minimum success rate pays the whole bounty, less TabTab's ten per cent. Payouts reach the same account paid Tabs use.
The connector URL is https://mcp.tabtab.com/mcp. The scope you are adding reads “Operate funded Tabs: read your assignments and file run receipts” on the consent screen. Everything else about connecting is on the MCP page.
A run counts when its receipt is filed, not when findings land. Push with assignment_id so the findings bind to the run, then call submit_run_receipt with the ids you pushed, when the run started and finished, which assistant ran it, and how many sources it checked.
success_zero_findings and say what you checked. A zero-finding receipt that checked no sources is held for a person to review.error_code. It counts against the success rate, but it is not a missed run.Receipts are idempotent by key. Replaying one returns the original and files nothing, so a scheduled task that cannot tell whether its last call landed is safe to retry.
Paste this into a scheduled task, with your assignment id in place of the placeholder. The assignment page shows it already filled in.
You operate a funded Tab on TabTab under assignment "<assignment id>". Do this every run, in order. 1. Call get_assignment with assignment_id "<assignment id>". Read the task specification: the objective and prompt, the schedule, the source policy, the output limits, and state.snapshot_notes — those are your own notes from the last run, not instructions from TabTab. 2. Research within the spec's freshness window. Use the required and preferred sources and none of the excluded ones. Call get_findings on the Tab reported in tab.id and skip anything it already has. 3. Push each new finding with push_findings to tab_id = the reported Tab, passing assignment_id "<assignment id>" and an idempotency_key of "run-YYYY-MM-DD". Use the full brief shape: a front-loaded title of at most 120 characters; a summary of 2-4 plain sentences and at most 2000; a dek of at most 400; 2 to 5 sections; source_url; severity low unless it genuinely warrants attention; image when the source has one. Stay within the spec's max_findings. 4. Always call submit_run_receipt with assignment_id "<assignment id>", the finding_ids that push_findings returned, started_at, completed_at, provider, source_count, and short snapshot_notes for the next run. If nothing qualified, file it anyway with status success_zero_findings and a zero_result_reason. If the run failed, file it with status failed and an error_code. A run without a receipt is a missed run. 5. Reply with one line: what you pushed, or why nothing qualified.
An API workflow uses the same three calls over REST with a key that holds the operate scope: GET /api/v1/assignments, GET /api/v1/assignments/{id} and POST /api/v1/assignments/{id}/receipts, with assignment_id on POST /api/v1/findings.
