Released on April 24, 2025, mcp-graphql-forge v0.3.0 is a focused update dedicated to improving observability. This release transforms the interaction between your MCP server and GraphQL endpoints from a "black box" into a transparent process, making it significantly easier for developers to build and troubleshoot their AI-powered GraphQL tools.

What’s new

The headline feature of v0.3.0 is the introduction of comprehensive debug logging via the new FORGE_DEBUG environment variable. By simply setting FORGE_DEBUG=true in your server configuration, you unlock deep visibility into the server’s inner workings:

  • Full Request Inspection: See exactly what’s being sent to your GraphQL endpoint, including raw payloads and HTTP headers.
  • Detailed Response Logs: Capture the HTTP status codes and response bodies, with automatic JSON pretty-printing for effortless readability.
  • Authentication Tracking: Verify that your token_command is working correctly by logging the Bearer tokens obtained during the authentication process.

Why it matters

Debugging in an MCP environment can be notoriously difficult because the server operates silently in the background of your AI client. When a tool fails, it’s often unclear whether the issue lies in the GraphQL query syntax, an unexpected API response, or a failed authentication handshake.

With v0.3.0, those guessing games are over. Whether you’re facing a "Forbidden" error or a malformed query, you now have the diagnostic data needed to pinpoint the root cause instantly. This drastically reduces the time-to-resolution and allows you to iterate on your curated GraphQL tools with confidence.

Getting started with v0.3.0

Upgrading to v0.3.0 is seamless and non-breaking; your existing forge.yaml and tool configurations remain fully compatible. Simply update your binary to the latest version.

To enable the new debugging capabilities, add the following environment variable to your MCP server configuration (for example, in your mcpConfig.json for Claude Desktop):

\"env\": {
  \"FORGE_DEBUG\": \"true\"
}

Once enabled, diagnostic information will be output to stderr, ensuring it stays separate from the standard MCP communication channel.
