MCP Server + Claude integration: credit usage and privacy/data access questions

1. My goal:
I want to understand how Claude and MCP servers work together inside Retool, specifically around credit usage and data privacy/access scope.

2. Issue:
When I connect an MCP server to Claude in Retool and build an app with it, I can't tell whether the usage draws from my own Claude/Anthropic credits thats included with my Claude plan or from Retool AI credits. I would also like some info on the privacy settings for MCP connections. What data or schemas Retool/Claude can see once a server is connected, and how access is scoped to specific resources rather than everything available if possible.

3. Steps I've taken to troubleshoot:

  • Checked the app builder settings for any credit/usage breakdown, didn't find a clear answer

  • Looked for documentation on MCP privacy/permissions within Retool, couldn't find detail on schema-level or resource-level access control
