What's Wrong?

Summary

When running a Remote Trigger, MCP tools configured via
mcp_connections (using connector_uuid from claude.ai
OAuth connectors) are not available in the remote session.
The agent reports all mcp__claude_ai_* tools as not found.

## Environment

• Claude Code CLI
• Remote Trigger execution (CCR)

## Actual Behavior

The remote agent cannot find any mcp__claude_ai_Notion__*
or mcp__claude_ai_Slack__* tools. It suggests adding
mcpServers to ~/.claude/settings.json, which is a local
config file inaccessible from the remote environment.

## Additional Context

• claude mcp list on local machine shows both Notion and

Slack as ✓ Connected

• Re-authenticating the OAuth connectors on claude.ai did

not resolve the issue

• connector_uuid for both Notion and Slack are correctly

specified in mcp_connections

## Question

Is connector_uuid-based MCP connection in Remote Triggers
supported? If so, what is the correct configuration?

What Should Happen?

## Expected Behavior

MCP tools defined in mcp_connections should be available
in the remote session, just as they are in a local Claude
Code session.

1. Create a remote trigger with mcp_connections using

connector_uuid for Notion and Slack

session_context.allowed_tools

1. Run the trigger manually via /run
2. The remote agent uses ToolSearch to find MCP tools →
