Sequesign vs Hindsight
A side-by-side look at the Sequesign and Hindsight MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Sequesign for cryptography work as a local process; choose Hindsight for knowledge & memory as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Sequesign when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a local stdio subprocess transport.
- You want tools like
sequesign_start_session, sequesign_record_action, sequesign_record_approval.
Choose Hindsight when
- You need dedicated capabilities in the Knowledge & Memory domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: API key required.
- You have the keys it needs:
HINDSIGHT_API_LLM_API_KEY.

Tools & capabilities
Sequesign tools 8
sequesign_start_sessionOpen 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_actionAppend a signed action to the chain. `evidence` is hashed and signed. Returns the `actionId`.sequesign_record_approvalAttach a locally signed approval for a recorded action (e.g. a human or agent reviewer signing off).sequesign_record_counterparty_attestationAttach 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_receiptAttach 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_receiptAttach an independently-witnessed **counterparty confirmation** to an *already-sealed* receipt (a deferred satellite), bound to a specific action.sequesign_finalizeSeal + witness the receipt and run the SDK's own verification. Closes the session.sequesign_verifyVerify 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…

Frequently asked questions
Sequesign is categorized under Cryptography and uses a local stdio subprocess. Hindsight belongs to Knowledge & Memory and uses a local stdio subprocess. Pick Sequesign for cryptography work and Hindsight for knowledge & memory.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Sequesign has no declared pricing — check the project's own site. Hindsight is listed as free. Auth: api key required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add sequesign and vectorize-io-hindsight as separate keys in the same mcpServers object, and your assistant will call tools from either one.
