Released on October 22, 2025, mcp-tf-provider-docs v0.2.1 is a maintenance update focused on strengthening the project’s foundation. This release ensures that our MCP server remains stable, secure, and fully compatible with the latest industry standards.

What’s new

This release focuses on critical updates to the project’s underlying toolchain and dependencies:

  • Go Toolchain Update: The project has been updated to Go 1.25.3, leveraging the latest performance improvements and security patches from the Go language team.
  • MCP Library Enhancement: We have updated the core mcp-go library from v0.32.0 to v0.41.1, ensuring better alignment with the evolving Model Context Protocol standards.
  • Infrastructure Refresh: Our CI/CD pipelines have been modernized with updated GitHub Actions, ensuring more reliable builds and better provenance tracking.

Why it matters

While this release doesn’t introduce new user-facing features, these internal updates are vital for the long-term health of the project. By staying current with the Go ecosystem and the MCP specification, we provide users with a more robust and reliable tool for indexing Terraform and OpenTofu provider documentation. This translates to better stability and performance when AI agents interact with the server to retrieve critical provider specifications.
