Can it analyze private GitHub repositories?

Yes, if you provide a GitHub token with access to those private repos.

What programming languages and package managers are supported?

It supports JavaScript/TypeScript (npm, yarn, pnpm, bun), Python (pip, poetry, uv, pdm, pipenv), Rust (cargo), Go (go), Java/Kotlin (maven, gradle), Ruby (bundler), and C/C++ (cmake).

Is the output format consistent and machine-readable?

Yes, all analysis results are returned as deterministic, structured JSON suitable for programmatic consumption.

Can I run this as a REST API or CLI tool?

Yes, it can be used as a Python library, CLI tool, REST API server, or MCP server.

Overview

This MCP server analyzes public GitHub repositories to provide structured, deterministic JSON data about their technology stack, dependencies, architecture, health metrics, and security indicators. It supports multiple ecosystems and outputs consistent, ground-truth information without using AI or LLMs. Use it when you need reliable, automated insights into repository characteristics for tooling, auditing, or integration with AI agents.

Use cases

Analyze a GitHub repo's tech stack and dependencies

Retrieve repository health and maintenance status

Detect security-related signals like Dependabot and branch protection

Integrate repo intelligence into AI agents via MCP

Expose repo analysis via REST API or CLI

Key features

Supports multiple languages and package managers (Python, JS, Rust, Go, Java, Ruby, C/C++)

Detects frameworks, CI/CD tools, test frameworks, and architecture traits

Provides repo metadata: stars, forks, license, languages, contributors

Outputs deterministic JSON with detailed repo insights

Available as Python library, CLI, REST API, and MCP server

Optional GitHub token support for private repo analysis and higher rate limits

Documentation Overview

RepoCrunch

Analyze any public GitHub repository into structured JSON. No AI, no LLMs — fully deterministic.

Give it a repo, get back tech stack, dependencies, architecture, health metrics, and security signals in clean, consistent JSON. Use it as a Python library, CLI tool, REST API, or MCP server.

Quick Start

Requires Python 3.11+.

Terminal

pip install repocrunch
repocrunch analyze fastapi/fastapi --pretty

That's it. Also works with uv:

bash

uvx repocrunch analyze astral-sh/uv --pretty

Install from source

bash

git clone https://github.com/kimwwk/repocrunch.git
cd repocrunch
uv venv && uv pip install -e ".[all]"

Install just what you need:

bash

uv pip install -e "."          # Library only (httpx + pydantic)
uv pip install -e ".[cli]"     # + CLI
uv pip install -e ".[api]"     # + REST API
uv pip install -e ".[mcp]"     # + MCP server
uv pip install -e ".[all]"     # Everything

Set a GitHub Token (optional)

Without a token you get 60 API calls/hour. With one, 5,000/hour. A token also lets you analyze private repositories you have access to.

server.ts

export GITHUB_TOKEN=ghp_...

Usage

CLI

bash

repocrunch analyze fastapi/fastapi --pretty          # Full analysis, pretty JSON
repocrunch analyze facebook/react -f tech_stack       # Single field
repocrunch analyze https://github.com/gin-gonic/gin   # Full URL works too
repocrunch serve                                       # Start REST API on :8000
repocrunch mcp                                         # Start MCP server (STDIO)

Python Library

server.ts

from repocrunch import analyze, analyze_sync

# Async
result = await analyze("fastapi/fastapi")

# Sync
result = analyze_sync("pallets/flask")

print(result.summary.stars)
print(result.tech_stack.framework)
print(result.model_dump_json(indent=2))

REST API

bash

repocrunch serve

# Then:
curl "http://localhost:8000/analyze?repo=fastapi/fastapi" | python -m json.tool
curl "http://localhost:8000/health"
curl "http://localhost:8000/docs"    # OpenAPI docs

MCP Server (for Claude, Cursor, etc.)

bash

repocrunch mcp    # Starts STDIO transport

Framework detection covers 40+ frameworks across all supported ecosystems (FastAPI, Django, React, Next.js, Spring Boot, Rails, Gin, Actix, and many more).

What It Detects

Category	Signals
Summary	Stars, forks, watchers, age, license, languages
Tech Stack	Runtime, framework, package manager, direct/dev dependency count, key deps
Architecture	Monorepo, Docker, CI/CD platform, test framework
Health	Commit frequency (daily/weekly/monthly/sporadic/inactive), maintenance status, contributors, open issues
Security	`.env` file committed, Dependabot enabled, branch protection, SECURITY.md present

Roadmap

Not yet implemented, but planned:

Secrets regex scanning — detect leaked API keys, tokens, passwords in the file tree
Architecture type classification — library vs. application vs. framework
API rate limiting — per-key throttling for the REST API
npm/npx package — npx repocrunch analyze owner/repo
Vulnerability scanning — known CVE detection in dependencies
Comparison mode — side-by-side analysis of multiple repos
Historical tracking — track how a repo's health changes over time
Platform deployments — Apify Store, Smithery, mcp.so, RapidAPI

Already shipped: RepoCrunch is published on PyPI — pip install repocrunch.
