Changelog

Dates are production release dates.

21 October 2026

• Developer docs. Published developers.usenylon.com: setup guides for each assistant, tool reference, authentication, limits, errors, troubleshooting, and security and data.

8 October 2026

• Microsoft Copilot Studio. Copilot Studio now sends search_library calls reliably. q is optional in the schema but still needed for each search.

29 September 2026

• Sessions. Idle sessions close after 2 hours, and each user can hold up to 100 live sessions. A closed or unknown session now returns 404, so clients reconnect cleanly.

20 August 2026

• New address. The server moved to https://mcp.usenylon.com/mcp with the Nylon brand.

6 August 2026

• Tool titles. Both tools carry display titles for assistant directories.

21 July 2026

• Paging. search_library accepts offset and limit, and says when more results are available.
• Jurisdiction hint. When a query names a jurisdiction the filter leaves out, the result says so.

20 July 2026

• Read-only annotations. Both tools declare readOnlyHint, destructiveHint: false and openWorldHint: false.

29 June 2026

• Citations. Results link to Nylon’s source viewer, and assistants are told never to invent case-law URLs.

23 June 2026

• Tools. Added search_library and read_document over Nylon’s library: New Zealand and Australian tax and law, and UK tax.
