Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`MERCURY_TOKEN_ACME_MAIN` Optional, secret	Example only. Each organization needs one read-only Mercury API token in the environment variable named by its token_env in your registry. Names are yours to choose but must match MERCURY_TOKEN_[A-Z0-9_]+ (for example MERCURY_TOKEN_<ENTITY_KEY>); set one per organization and rename this example to…
`MERCURY_ENTITIES_FILE` Optional	Alternative to --entities: path to the entity registry YAML. Ignored when --entities is passed.
`MERCURY_API_BASE` Optional	Mercury API host. Allowed without extra flags: https://api.mercury.com, https://api-sandbox.mercury.com (with sandbox tokens), or a loopback mock.
`MERCURY_ALLOW_DOCUMENTS` Optional	Set to true to register get_statement_pdf and get_invoice_pdf, which return statement and invoice PDFs unredacted. Off by default.
