About Sequesign

Sequesign is an MCP server published by the GitHub account Sequesign. Cryptographically verifiable receipts of an agent's delegated work, verified offline.

It runs on your own machine: your AI client starts it from the npm package @sequesign/mcp at version 0.4.1.

It asks for 3 secrets: SEQUESIGN_API_KEY, SEQUESIGN_AGENT_PRIVATE_KEY and SEQUESIGN_TEMPLATE_REGISTRY_TOKEN. Give it a key with the least access that still works.

Version 0.4.1 was published on 21 August 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 1 warn, 0 fail, 1 info. How we check.

What it asks for

VariableRequiredSecretDescription
SEQUESIGN_MODENoNoTransport: 'direct' (default; sign locally, an independent witness co-signs) or 'managed' (route through the Sequesign broker for a registered identity).
SEQUESIGN_API_KEYNoYesSequesign write-class API key (from the dashboard). Required for managed mode; in direct mode it authenticates the hosted witness.
SEQUESIGN_AGENT_PRIVATE_KEYNoYesEd25519 PKCS#8 private-key PEM for the agent. In managed mode, the key registered to your API key. In direct mode, omit to mint an ephemeral key per session.
SEQUESIGN_PACKAGE_DIRNoNoDirectory where sealed receipt packages are written. Defaults to a temporary directory.
SEQUESIGN_TEMPLATE_REGISTRY_URLNoNoBase URL of a read-only dynamic template registry (e.g. https://dashboard-api.sequesign.com/v1/registry). When set, direct-mode sessions and the discovery tools resolve templates published there in addition to the bundled ones, falling back to bundled offline. Omit to use only the bundled templates.
SEQUESIGN_TEMPLATE_REGISTRY_TOKENNoYesRead-only bearer token for an account-scoped template registry (discovery only; never used in verification). Omit for a public registry.
