We’re excited to announce the release of mcp-graphql-forge v0.3.0! Published on April 24, 2025, this update introduces debug logging capabilities that make it easier than ever to troubleshoot issues with your GraphQL integrations.

This focused enhancement adds the FORGE_DEBUG environment variable, giving users visibility into GraphQL API interactions without changing any existing behavior. Whether you’re debugging authentication problems, validating query syntax, or simply want to understand what’s happening under the hood, v0.3.0 has you covered.

What’s New

FORGE_DEBUG Environment Variable

The headline feature in v0.3.0 is the new FORGE_DEBUG environment variable. Set it to enable detailed debug logging for all GraphQL API interactions:

export FORGE_DEBUG=true
mcp-graphql-forge

Or run it inline for a single session:

FORGE_DEBUG=true mcp-graphql-forge

When enabled, the server logs comprehensive information to stderr, including:

  • Full HTTP requests – See exactly what queries and variables are being sent to your GraphQL endpoint
  • Response details – View status codes and response bodies (JSON is pretty-printed when possible)
  • Token retrieval – Confirm authentication tokens are being obtained correctly (when using token_command)

The debug mode starts with a simple “Debug mode enabled.” message on startup, followed by clearly marked request/response blocks for each GraphQL interaction.

Backward Compatibility

v0.3.0 is a safe upgrade for all existing users:

  • No breaking changes
  • Debug logging is opt-in and disabled by default
  • All existing configurations continue to work without modification

Why It Matters

Debugging MCP integrations with GraphQL backends used to involve a lot of guesswork. v0.3.0 removes that friction by providing direct visibility into the server’s operations.

Practical use cases:

  1. Troubleshooting connection issues – Instantly see if requests are reaching your GraphQL endpoint and what responses you’re getting
  2. Authentication verification – Confirm that your token command is working and that authorization headers are being set correctly
  3. Configuration validation – Validate that your YAML tool definitions translate to valid GraphQL queries before deploying to production
  4. Development workflow – Speed up iteration cycles by immediately seeing the effect of configuration changes

For developers building MCP integrations, DevOps engineers maintaining production deployments, or anyone working with custom GraphQL backends, this observability improvement significantly reduces the time spent diagnosing issues.

Getting Started

Upgrading

Pre-built binaries for v0.3.0 are available on the GitHub Releases page. Download the asset matching your platform:

Platform Architecture Asset
macOS (Intel) amd64 mcp-graphql-forge-v0.3.0-darwin-amd64.tar.gz
macOS (Apple Silicon) arm64 mcp-graphql-forge-v0.3.0-darwin-arm64.tar.gz

Windows x64 mcp-graphql-forge-v0.3.0-windows-amd64.zip

Each release includes SHA256 and MD5 checksums for verification.

Using Debug Mode

Enable debug logging when you need it:

# Troubleshoot an issue
export FORGE_DEBUG=true
mcp-graphql-forge
# ... observe logs, identify the problem ...

# Disable when done (start a fresh session without the env var)
unset FORGE_DEBUG

Security Note

When debug mode is enabled, authentication tokens are logged in plaintext. Please use caution:

  • Only enable FORGE_DEBUG in secure environments
  • Clear or redact logs before sharing them
  • Avoid committing debug output to version control

What’s Next

v0.3.0 demonstrates our commitment to improving the developer experience for mcp-graphql-forge users. Enhanced observability was a clear need, and this release addresses it with minimal friction and maximum utility.
