[BUG] CCR scheduled triggers: MCP connectors not available as tools in remote agent session

What's Wrong?

CCR scheduled triggers: MCP connectors attached via mcp_connections are not available
as tools in the remote agent session. The agent only sees general-purpose tools (Bash,
Read, WebSearch, etc.) and has no access to the configured MCP integrations (Gmail,
Google Calendar, Notion).

What Should Happen?

The remote agent should have access to the MCP tools from the attached connectors, the
same way they are available in a local Claude Code session with the same connectors
configured.

Error Messages/Logs

I don't have the MCP integrations needed to access your Google Calendar, Gmail,
  or Notion data. The required authenticated tools (Google Calendar API, Gmail API,
  Notion API) are not configured in this environment. The tools available to me are
  only general-purpose ones (web search/fetch, file I/O, etc.), none of which have
  authenticated access to your Google or Notion accounts.

Steps to Reproduce

1. Create a CCR scheduled trigger via the API with mcp_connections specifying one or

more claude.ai MCP connectors (Gmail, Google Calendar, Notion)

1. Run the trigger manually via the run endpoint
2. Observe that the agent reports no MCP tools available and cannot execute any steps

requiring authenticated integrations

Additional context: Trigger ID trig_01C6YT4ZBAckeVGjZX6P6yiA. Same prompt works
correctly in a local Claude Code session with identical MCP connectors. Removing
allowed_tools restrictions from session_context made no difference. Claude Sonnet 4.6.
