How Github compares

Against every graded Developer tools MCP server, from our own scans and uptime checks. Updated after each scan run.

Safety score: 80/100; higher than 55% of 1,119 Developer tools servers
Tools: 1; the typical Developer tools server has 7
Tools that change things: 100%; typical: 5%. Fewer write tools means less an agent can break
GitHub stars: 5; more than 78% of 855 Developer tools servers
Downloads a week: 153; more than 66% of 436 Developer tools servers with a package

🚀 AI-Optimized for Token Efficiency

This server is designed with AI agents in mind:

Response Formats

Real-World Savings

Smart Usage

// Default: Use compact for most operations
const issues = await callMCPTool("github_list_issues", {
  owner: "user", repo: "repo",
  limit: 10,
  response_format: "compact"  // 94% smaller!
});

// Use json only when you need every field
const fullIssue = await callMCPTool("github_get_issue", {
  owner: "user", repo: "repo",
  issue_number: 42,
  response_format: "json"
});

Combined with our code-first architecture (98% token reduction), you get the most efficient GitHub MCP server available.

Nothing above is checked by us. What we check is on the safety report.

Github: common questions

Is Github MCP server safe?: Mostly: it is graded B (80/100). Read the Github safety report
How do I install Github?: It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
Does Github need an API key?: Not as far as the registry entry and our scan can tell: no credentials are declared or required.
Is Github maintained?: The last commit was 99 days ago (2026-07-28). The latest release is v2.5.7.
What can I use instead of Github?: Servers from other publishers that do the same job: Contextatlas MCP server, GitDiagram MCP server and Gk CLI MCP server.
How does Github compare with other Developer tools MCP servers?: safety score 80/100 (higher than 55% of 1,119 Developer tools servers); tools 1 (the typical Developer tools server has 7); tools that change things 100% (typical: 5%. Fewer write tools means less an agent can break). Full comparison.
