MCP for GitHub PR, Issues, Tags and Releases
   
The Model Context Protocol (MCP) is an open standard that enables seamless integration between Large Language Models (LLMs) and external tools. Whilst it can be implemented in any AI system, including custom LLM setups, the degree of integration and optimisation varies based on the model's architecture and capabilities.
This MCP application serves as a bridge between LLMs and GitHub's repository management features, offering automated analysis of pull requests and comprehensive issue management. It provides a robust set of tools to fetch PR details, create issues, and update issues directly from your desktop LLM. The application is designed with modularity in mind, supporting extensibility via the MCP tool interface and seamless integration with existing workflows.
The toolset enables automated PR analysis, issue tracking, tagging and release management through a standardised MCP interface, making it ideal for teams seeking to streamline their GitHub workflow automation.

Requirements
- Python 3.12+
- GitHub Personal Access Token (with
reposcope) or a GitHub OAuth App (client ID, secret, and a public base URL)
Authentication
Two auth modes are supported. The active mode is selected automatically from environment variables.
| Mode | When active | Token used for API calls | |------|-------------|--------------------------| | Static token (default) | GITHUB_TOKEN set; no GITHUB_OAUTH_ vars | Server's GITHUB_TOKEN for all calls | | GitHub OAuth2 | GITHUB_TOKEN + all three GITHUB_OAUTH_ vars set | Each user's own gho_* token |
Environment Variables
| Variable | Required | Description | |----------|----------|-------------| | GITHUB_TOKEN | Yes | GitHub PAT with repo scope; used as the Bearer token in static-token HTTP mode | | MCP_ENABLE_REMOTE | No | Any non-empty value enables HTTP mode (required for OAuth2) | | GITHUB_OAUTH_CLIENT_ID | OAuth2 only | GitHub OAuth App client ID | | GITHUB_OAUTH_CLIENT_SECRET | OAuth2 only | GitHub OAuth App client secret | | GITHUB_OAUTH_BASE_URL | OAuth2 only | Public base URL of the MCP server (used for the OAuth2 redirect) | | REDIS_HOST_PORT | No | Redis connection string. Accepts host:port or a full URI: redis://[:password@]host:port[/db] (plaintext) or rediss://[:password@]host:port[/db] (TLS). When set, OAuth token state is stored in Redis instead of in-process memory. | | REDIS_PASSWORD | No | Redis AUTH password fallback — used when the password is not embedded in the URI. | | PORT | No (default 8081) | HTTP server port | | HOST | No (default localhost) | HTTP server host | | GITHUB_API_TIMEOUT | No (default 5) | Timeout in seconds for GitHub API requests |
To create a GitHub OAuth App, go to Settings → Developer settings → OAuth Apps → New OAuth App and set the Authorization callback URL to
<GITHUB_OAUTH_BASE_URL>/auth/callback(e.g.https://mcp.example.com/auth/callback).

- PR Management: Fetch diffs, content, linked issues, CI status - create, review, merge, and update
- Issue Tracking: Create, update, list, and assign
- Release Management: Tags and releases
- User Search: Profile lookup and activity tracking via GraphQL
Main Flows
- MCP Client: Interacts via stdio or streamable HTTP
- Auth Layer: Selects APIKeyVerifier (static token) or GitHub OAuth2 provider; token state in MemoryStore or RedisStore
- PRIssueAnalyser: FastMCP server - handles tool registration and request routing
- GitHub Integration: All GitHub API calls (REST v3 + GraphQL v4)
Local Installation
- Clone the repository:
git clone https://github.com/saidsef/mcp-github-pr-issue-analyser.git
cd mcp-github-pr-issue-analyser- Install dependencies:
Launch MCP in stdio mode. ``sh export GITHUB_TOKEN="<github-token>" uvx ./ ``
Alternatively, launch MCP in http mode. ``sh export GITHUB_TOKEN="<github-token>" export MCP_ENABLE_REMOTE=true uvx ./ ` > You can access it via http i.e. http(s)://localhost:8081/mcp > In HTTP mode, clients must authenticate with Authorization: Bearer <GITHUB_TOKEN>`.
Alternatively, launch MCP in http mode with GitHub OAuth2 authentication. ``sh export GITHUB_TOKEN="<github-token>" export MCP_ENABLE_REMOTE=true export GITHUB_OAUTH_CLIENT_ID="<oauth-app-client-id>" export GITHUB_OAUTH_CLIENT_SECRET="<oauth-app-client-secret>" export GITHUB_OAUTH_BASE_URL="https://<your-public-host>" uvx ./ `` > In OAuth2 mode, users authenticate via GitHub's OAuth flow. Each user's own GitHub token is used for API calls.
Alternatively, run via Docker using the published image. ``sh docker run -e GITHUB_TOKEN="<github-token>" \ -p 8081:8081 \ ghcr.io/saidsef/mcp-github-pr-issue-analyser:latest ``
Local Integration with IDEs and LLMs
To add an MCP server to your IDE or LLM, you need to add this section to the configuration file. The basic structure involves defining a server name and providing the command and any necessary arguments to run the server.
