What
MCP server configurations now support a request_timeout_ms field that raises the per-request fetch deadline and the tool-call watchdog for that specific server.
Details
- Set by the host via
mcp_set_serverscontrol event; not a user-editable field in.claude/settings.json - Capped at 5 minutes
- Applies to both stdio and SSE server types
- Overridden if
timeoutis also set on the server
Evidence
Schema description (search for "Per-server HTTP request timeout in milliseconds, set by the host on the mcp_set_servers control event")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
