MCP Server Upgraded to the Latest Protocol Revision

Our MCP server now speaks the latest protocol revision with better tool metadata and fixed connectivity issues, while staying fully compatible with existing clients:

  • MCP server on the newest protocol revision: The MCP server now supports the latest protocol revision (2026-07-28). Existing clients on the previous revision, including Claude's connector, continue to work exactly as before with no changes required on your end.
  • Fixed browser-based MCP clients failing to connect: A missing set of headers in cross-origin requests was silently blocking browser-based MCP clients from connecting at all. This is now fixed.
  • Fixed OAuth discovery returning 404: Clients doing OAuth resource discovery against our MCP server's protected resource path were getting a 404 instead of the metadata document. Discovery now works correctly, including additional metadata like supported scopes and a link to documentation.
  • Structured output on every MCP tool: All 28 MCP tools now return a structured, machine-readable result alongside the existing text output, so clients that support the new revision can consume results directly instead of parsing text.
  • Clearer tool titles and behavior hints: Every tool now carries a human-readable title and accurate annotations, so MCP clients can correctly show which actions are read-only versus which make changes, and which changes are destructive.
  • Corrected MCP documentation: The MCP README and docs now correctly list all 28 tools (previously showing 26 and missing two), the correct port, an up-to-date authentication section, and the correct platform count of 11, including Vimeo which had been missing from the list.
  • Claude Code Plugin documentation: Added a new documentation page covering installation, features, and commands for the Claude Code Plugin, with links to it from the docs navigation and llms.txt.
