The draft was just promoted as 2025-03-26, this issue tracks its adoption

modelcontextprotocol/modelcontextprotocol#232

  • Adopt HTTP+SSE in a backwards-compatible way
  • Assess tool annotations as a way to inform confirmations
  • Adopt progress notifications now that they include messages
  • ✋ Audio content. We need to support this in copilot/LM APIs generally first

Also in the spec: ToolAnnotations , which doesn't have much documentation but needs reading the schema.

Parts of this could be show in the UI, while others can be used as hints.

Via pulsemcp's update:

Servers can now label individual tools with tags like "destructive", "idempotent", "openWorld", and "readOnly". Clients are meant to treat these annotations as hints (i.e. they should not trust untrusted servers to self-report properly), but it should unlock some great efficiencies with respect to dodging the alarm fatigue you get when having to repeatedly click "Allow Tool Call".

mcp: support streamable HTTP
8f85566 
This PR adds support for 'streamable HTTP' MCP servers. This is
backwards-compatible with existing SSE servers. We'll first try to
initialize the server in streamable HTTP mode, and then fall back to
legacy SSE if that fails.

This PR also adds our own small SSE parser, `eventsource` was too high
level to do what we need to do.
