GitHub MCP Server 0.31.0

Highlights

Streamable HTTP Support

The GitHub MCP Server now includes native Streamable HTTP support via a new http command, bringing much of the HTTP Streamable functionality previously hosted at api.githubcopilot.com/mcp directly into this repository. See the documentation for setup and usage details.

Insiders Mode

A new opt-in mode for experimental tooling and features. The first experiment available through Insiders Mode is MCP Apps — see the discussion for more details. Instructions for enabling Insiders Mode can be found in the README.

Context Reduction

Tool responses across multiple tools have been significantly trimmed, reducing context usage and improving efficiency for LLM interactions.

Copilot Tools Enabled by Default

Copilot-related tools are now included in the default toolset. When using api.githubcopilot.com/mcp, tools that aren't available for your Copilot plan are automatically hidden.
