ShelfLayer Connect
Public beta terms

Terms of service.

These terms govern access to ShelfLayer, a read-only MCP server for searching and citing public-domain books during the public beta.

Short version

ShelfLayer is free during public beta, read-only, and provided as-is. Use it responsibly, do not abuse the service, and verify important outputs against the cited sources.

Access and accounts

You may need to sign in with Google through Clerk to connect an MCP host to ShelfLayer. You are responsible for activity from your account and for disconnecting the integration from MCP clients you no longer use.

The service

ShelfLayer provides tools for searching shelves, books, sections, passages, and citation metadata from a public-domain book index. The service does not create, modify, or delete user data through MCP tools.

Acceptable use

  • Do not attempt to bypass authentication, rate limits, or access controls.
  • Do not overload, probe, scrape, or disrupt the service.
  • Do not use ShelfLayer to submit private, regulated, or confidential data.
  • Do not misrepresent ShelfLayer outputs as a substitute for professional advice.

Content and citations

ShelfLayer indexes public-domain texts and returns passages, metadata, and citations to help AI agents inspect sources. We aim for useful retrieval, but search results, metadata, categorization, and citations may contain errors. You should verify important claims before relying on them.

Beta availability

The public beta may change, pause, or end as the product develops. Features, limits, pricing, indexes, and authentication behavior may be updated before general availability.

No warranties

ShelfLayer is provided as-is and as-available. To the maximum extent permitted by law, we disclaim warranties of accuracy, availability, fitness for a particular purpose, and non-infringement.

Limitation of liability

To the maximum extent permitted by law, ShelfLayer will not be liable for indirect, incidental, consequential, special, exemplary, or punitive damages, or for lost profits, lost data, or service interruptions arising from use of the public beta.

Changes

We may update these terms as ShelfLayer evolves. Continued use of the service after changes means you accept the updated terms.
