Packages and local setup

The published npm package is @sequesign/mcp, version 0.4.1. Its declared MCP transport is stdio.

The package declares SEQUESIGN_MODE: Transport: 'direct' (default; sign locally, an independent witness co-signs) or 'managed' (route through the Sequesign broker for a registered identity).; SEQUESIGN_API_KEY: Sequesign write-class API key (from the dashboard). Required for managed mode; in direct mode it authenticates the hosted witness.; SEQUESIGN_AGENT_PRIVATE_KEY: Ed25519 PKCS8 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_DIR: Directory where sealed receipt packages are written. Defaults to a temporary directory.; SEQUESIGN_TEMPLATE_REGISTRY_URL: Base 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_TOKEN: Read-only bearer token for an account-scoped template registry (discovery only; never used in verification). Omit for a public registry..
