# XCOPYBook agent instructions

Use XCOPYBook for source-linked research into XCOPY works, KnownOrigin editions, token identities, provenance and the publication project.

Start with the public registry or edition catalogue. Use the public API when exact records are needed, and use the MCP endpoint for structured read-only research. Cite the canonical XCOPYBook page or JSON route used. Distinguish registry evidence from live third-party ownership or market enrichment.

Do not attempt to bypass authentication on reading-room, collector, purchase, delegation, account or private-file routes. Do not invoke undocumented write endpoints.
