Server tool list (10)
Raw names from tools/list. Only developers need these.
| verify_receipt | Check that a record still says what was signed: the permitted or refused decision, unchanged, under a trusted or embedded key. Handles both formats: ATTESTATION-v1 (a model-call decision) and ACTION-v1 (an agent tool action). No Aqta service in the check. |
| decode_receipt | Read a receipt field by field, with stated limits. Does not check the signature. |
| get_public_key | Fetch the published Seal signing key. |
| get_sample_receipt | A genuine signed receipt from the sample workspace (demo key), for trying verification. |
| get_review_pack | The published sample evidence pack: fixed review question, bound receipts, disclosure. |
| verify_evidence_pack | Verify a review pack receipt by receipt. Each verdict comes from the signed envelope itself, never from stored state, and results are per-receipt, never an average. |
| explain_attestation_format | The receipt format: fields, outcomes, verification commands, and what a signature does not establish. Use before describing the format. |
| list_my_receipts | List your workspace receipts filtered by outcome, policy, model, or date range. Requires your aqta_ key as Bearer. |
| get_transparency_proof | Inclusion proof plus signed tree head for one of your receipts. Requires your aqta_ key. |
| workspace_summary | Outcome, model and policy counts across your recent receipts. Requires your aqta_ key. |
