• Gumroad tools appear as mcp__metorial__<tool>. Use that name in permission rules to allow or deny a tool.
• Run /mcp to see whether Metorial is connected and to sign in again.
• Claude Code warns when a tool result passes 10,000 tokens and caps it at 25,000 by default. Raise the cap with MAX_MCP_OUTPUT_TOKENS.
• Pre-approve trusted Gumroad tools with allow rules in your settings so Claude Code stops asking each time.

claude mcp list shows "Needs authentication"

Run /mcp, select Metorial, and sign in. If sign-in keeps failing, choose Clear authentication in the same menu and sign in again.

A teammate sees "Pending approval"

Servers shared through a project .mcp.json need approval. Run claude in the project and approve Metorial when asked.

Large tool results are cut off

Claude Code limits MCP tool output to 25,000 tokens by default. Raise it with the MAX_MCP_OUTPUT_TOKENS environment variable.
