GitHub MCP Server 0.32.0

Highlights

Context Reduction

This release brings context optimisations to get_files, get_pull_request_review_comments, get_pull_request_reviews, add_issue_comments, list_pull_requests, list_tags, list_releases, and list_issues. Tool outputs have been trimmed to only retain information that the LLM needs.

Copilot Tools in Default Toolset

Copilot-specific tools have been moved into the default copilot toolset, making them available out of the box without additional configuration.

MCP Apps UI Improvements

Several enhancements to MCP Apps rendering - including better client support detection, clearer user confirmation prompts for issue and PR creation, and smarter form skipping when issue updates include a state change.

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.
