Description:
This PR introduces an RFD for adding a new session/update_servers request to the Agent Client Protocol.
Motivation: Currently, MCP servers can only be provided during session setup (session/new, session/load, etc.). Once a session is established, its list of MCP servers is fixed. This forces users to restart their sessions (losing valuable context and history) just to add, remove, or reconfigure an MCP server.
Proposed Changes:
Introduce a session/update_servers request sent by the Client to the Agent.
The request payload contains the full replacement list of MCP servers (reusing the existing
McpServer
schemas).
The Agent gracefully connects to newly introduced servers and disconnects from those removed from the list.
Impact: This allows clients to confidently provide live MCP server management UIs. Settings changes to MCP configurations can instantly propagate to active agent sessions without interrupting the user's workflow.
Based on the feature request in discussion #556.
