Case Study: Connecting GitHub MCP to Claude Sonnet and GPT-5 APIs

3 min read

Introduction

Developers are increasingly blending multiple LLMs into their workflow. Connecting GitHub's MCP server with Claude Sonnet and GPT-5 through JuheAPI unlocks synchronized multi-LLM automation without leaving your repository environment.

GitHub MCP Overview

Core Capabilities

  • Repository Management: Create, list, and validate repositories.
  • Branch Lifecycle: Securely create, list, and delete branches.
  • Issue Handling: Create, list, and filter by state.
  • Pull Requests: Create, update, merge with multiple strategies.
  • File Editing: Create/update with Base64 support.
  • Releases: Draft and publish tagged releases.

Installation & Setup

Prerequisites:

  • Node.js v16+
  • GitHub personal access token

Steps:

  1. Clone repository:
git clone https://github.com/cyanheads/github-mcp-server.git
cd github-mcp-server
  1. Install dependencies:
npm install
  1. Environment variables:
GITHUB_TOKEN=your_github_personal_access_token
LOG_LEVEL=info
SERVER_NAME=github-mcp-server
  1. Build & start:
npm run build
node build/index.js

JuheAPI Multi-LLM Endpoints

What They Offer

JuheAPI provides simultaneous connections to multiple LLMs like Claude and GPT from a single API call.

Why They Fit MCP

MCP’s standardized interface means the GitHub context can be cleanly passed to specific LLM endpoints, returning structured actions.

Integrating Claude Sonnet via MCP

Configuring Endpoint

Set up an MCP tool targeting Claude Sonnet's JuheAPI route with repository context payloads.

Running Repository Queries

Example: Claude can generate detailed issue descriptions by analyzing file diffs retrieved via MCP.

Integrating GPT-5 via MCP

Jobs Best Suited

  • Complex code reviews
  • Designing branch strategies

Example: Pull Request Review

MCP fetches PR details and sends them to GPT-5 via JuheAPI to get architectural feedback.

Parallel Use: Claude + GPT-5

Coordinating Responses

Attach IDs to MCP calls to each LLM, then reconcile results in a merged GitHub comment.

Automated Workflows

Use Claude for summarization and GPT-5 for in-depth code analysis in one MCP-driven CI step.

Practical Walkthrough

Quick Start Example

  1. Configure MCP tools for Claude and GPT-5 endpoints via JuheAPI.
  2. Request: MCP fetches latest commits and sends:
{
  "llm": "claude-sonnet",
  "context": "recent commits"
}
  1. Claude summarizes changes; GPT-5 proposes refactor.

Debugging Tips

  • Verify endpoint URLs in JuheAPI.
  • Check MCP logs for payload formatting.

Benefits & Limitations

Benefits:

  • Unified workflow in GitHub
  • Multi-LLM insight without manual copy/paste
  • Scalable automation

Limitations:

  • Requires careful token management
  • LLM quota limits
  • Coordination overhead

Conclusion

By combining GitHub MCP’s powerful API integration with JuheAPI’s multi-LLM endpoints, developers can orchestrate Claude Sonnet and GPT-5 in parallel, automating repository management and code intelligence directly inside their dev flow.
