Lucernel Public Tools

Lucernel Public Tools

Live API operations, verified October 23, 2026. Five public operations across four sites are deployed and available. Use the @lucernel/public-tools package or this source checkout for the CLI and optional MCP server.

This repository documents small, unauthenticated JSON tools from four independent sites:

Read API behavior, errors, limits, and privacy before integrating. Each site has its own origin and quota, with site-specific limiter state. The local CLI is covered in CLI usage. Optional local stdio integration is documented in MCP server setup.

The lucernel-tools CLI requires Node.js 22 or later. Run bunx --package @lucernel/[email protected] lucernel-tools --help, or follow the source instructions below.

These tools use existing site calculations or data. They do not require authentication, call AI services, or access application databases. Matrice premium readings and PDFs, private account data, and Musael manuscripts are outside this API.

API specifications and Postman collections

The files below describe the live route contracts. Production responses were checked against all five tool contracts on October 23, 2026.

The direct API endpoints are free to use, with no login, key, subscription, or paid tier. Apply bounded retries only: honor Retry-After for 429/503, do not retry validation errors, and never change networks or accounts to evade a quota.

See distribution status for the public package, MCP Registry entry, marketplace links, and checks still pending. Third-party gateways have their own account requirements and quotas.
