Description
The PipeCD Docs MCP Server currently doesn't work with Claude Desktop and VS Code due to console.info writing to stdout which is reserved for MCP JSON-RPC communication. A fix has been identified and a new release is needed
Problem
The server uses console.info in src/loader.ts (lines 28 and 39) which writes to stdout. Since MCP uses stdout for JSON-RPC communication, Claude Desktop and VS Code fail to connect with:
Unexpected token 'S', "Successful"... is not valid JSON
Impact
Claude Desktop: Fails to connect (strict JSON parsing on stdout)
VS Code: Fails to connect (strict JSON parsing on stdout)
Cursor: Appears to work (likely ignores non-JSON stdout lines)
A new release is needed after the fix for npx @pipe-cd/docs-mcp-server@latest to work with Claude Desktop and VS Code
