Released on December 17, 2025, mcp-graphql-forge v0.9.0 introduces a powerful new way to optimize how your AI agents consume data from GraphQL APIs. This release focuses on efficiency, giving you granular control over how tool responses are formatted to maximize performance and minimize token costs.

What’s new

The standout feature of v0.9.0 is the introduction of Configurable Output Formats. You can now specify how each GraphQL tool’s response is formatted directly in your YAML configuration using the output property.

Depending on your needs, you can choose from three formats:

  • raw (Default): Returns the server response exactly as received, ideal for maximum transparency.
  • json: Provides minimized JSON by stripping unnecessary whitespace, reducing the token payload.
  • toon (Token-Oriented Object Notation): A specialized format designed specifically for LLMs. For tabular or uniform data, TOON can reduce token consumption by as much as 30-60%, allowing your agents to process more information within the same context window.

To ensure reliability, v0.9.0 includes a graceful fallback mechanism. If a requested transformation to json or toon fails, the server automatically reverts to raw output, ensuring your tools always return data.

Why it matters

In the world of LLMs, tokens are the primary currency. Large GraphQL responses can quickly consume a context window or increase operational costs. By introducing token-efficient formats like TOON, mcp-graphql-forge allows you to:

  • Reduce Costs: Lower the number of tokens sent to your LLM.
  • Increase Capacity: Fit more data into a single prompt by compressing the response format.
  • Improve Flexibility: Tailor the output of each tool individually—using raw for debugging and toon for high-volume data extraction.

Getting started with v0.9.0

Upgrading to v0.9.0 is seamless. Since the new configuration options are opt-in, your existing setups will continue to work without modification.

You can upgrade by downloading the latest pre-compiled binaries from the GitHub Releases page, or by installing directly via Go:

go install github.com/UnitVectorY-Labs/mcp-graphql-forge@latest
