Chloe by Dyme

Versions and changes

The Dyme MCP server has one version number, sent as serverInfo.version when an assistant connects and as version in tools.json. tools.json also carries a fingerprint: a short hash of every tool's name, arguments and hints. If the fingerprint you saw last differs from today's, the tools have changed, and this page says how.

How the version moves

Change Version
A tool is removed or renamed, or an argument is removed or becomes required Major (2.0.0)
A tool or an optional argument is added Minor (1.2.0)
Wording, results or fixes, with the same tools and arguments Patch (1.1.1)

A tool or argument that is going away is marked here at least 30 days before it is removed.

1.1.2, 8 November 2026

Tool fingerprint: 68a57b23cf2a (unchanged)

  • Every argument now has a description. 63 had none; the tool reference showed blank cells for them.

1.1.1, 7 November 2026

Tool fingerprint: 68a57b23cf2a (unchanged: no tool or argument changed)

  • The tool reference now carries every argument's description and type, and a deprecated note on tools that are going away.
  • request_cancellation is marked deprecated in tools.json; use request_change with kind: "cancel".
  • Two tool titles and the over-allowance message now use US spelling ("traveler").
  • New: GET /health (public, no sign-in), ETags on /docs/* so a client can check for changes with If-None-Match, and the Quickstart and For developers pages.
  • Corrections to the docs: allowances and caps are counted per server today; a price comparison waits up to 40 seconds before answering with a filling-in card; the exact error wording.

1.1.0, 7 November 2026

Tool fingerprint: 68a57b23cf2a

  • First published version of the tool reference and these docs.
  • Every argument has a declared type.
  • Every tool carries annotations.title and a read-only or destructive hint.
  • 46 tools: 40 the assistant's model uses and 6 that only the result cards call.

Planned changes

  • request_cancellation will be retired in a future major version. request_change with kind: "cancel" does the same thing and is the one to use.

Earlier versions were not recorded.
