Cryptographically verifiable receipts of an agent's delegated work, verified offline.
AI-powered task management system for AI-driven development. Features PRD parsing, task expansion, multi-provider support (Claude, OpenAI, Gemini, Perplexity, xAI), and selective tool loading for optimized context usage.
Open a recording session (one signed action chain). Returns a `sessionId` (the receipt id) used by every other tool. Pass a `policyContext` object to bind the receipt to a policy (reaches `L3_POLICY_BOUND`). Optional `mode` (`direct`/`managed`) overrides the server default per session.
sequesign_record_action
Append a signed action to the chain. `evidence` is hashed and signed. Returns the `actionId`.
sequesign_record_approval
Attach a locally signed approval for a recorded action (e.g. a human or agent reviewer signing off).
sequesign_record_counterparty_attestation
Attach a counterparty's signed confirmation of a recorded action (e.g. a vendor confirming an amount). The SDK derives the content binding from the attested action.
sequesign_approve_receipt
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).

Attach an independently-witnessed **approval** to an *already-sealed* receipt (a deferred satellite). For a reviewer — human or another agent — signing off after the fact. The approver must be distinct from the recording agent.
sequesign_countersign_receipt
Attach an independently-witnessed **counterparty confirmation** to an *already-sealed* receipt (a deferred satellite), bound to a specific action.
sequesign_finalize
Seal + witness the receipt and run the SDK's own verification. Closes the session.
sequesign_verify
Verify a sealed receipt offline. Three modes: integrity self-check of the local package (default); third-party `external` check when you pass the witness's published keys; or pass `receiptUrl` to verify the broker-**stored** receipt (the authoritative copy carrying the registered identity), auto-fe…
