ProjectPulse MCP 🏥

GitHub repository health monitoring for AI assistants — works with any language, any repo.

---

This Model Context Protocol (MCP) server gives AI assistants the ability to analyze health, security, CI/CD status, and delivery metrics of any GitHub repository — directly from your conversations.

✨ Features

• 🏥 Health Score — comprehensive 0-100 score with grade (A-F), category breakdown, and improvement suggestions
• 🔒 Security — Dependabot alerts blended with OpenSSF Scorecard checks (60/40 weighted)
• 📊 DORA Metrics — proxy DORA metrics from GitHub data: deployment frequency, lead time, change failure rate, MTTR
• 🔍 Code Scanning — CodeQL and other code scanning alerts with severity, message, and creation date
• 📦 Dependency Analysis — Dependabot alerts with severity filtering
• ⚙️ CI/CD Status — recent GitHub Actions workflow runs and conclusions
• 📋 Repository Info — stars, forks, language, license, and general metadata

🚀 Quick Start

Claude Code (CLI)

claude mcp add projectpulse -- npx projectpulse-mcp

Note: You need a .env file with your GITHUB_TOKEN in the directory where you run Claude Code.

Claude Desktop

Step 1: Get a GitHub Token

1. Go to GitHub Settings > Developer settings > Personal access tokens > Fine-grained tokens
2. Give it a name (e.g., projectpulse)
3. Select the repositories you want to monitor (or "All repositories")
4. Under Permissions, grant Read-only access to:
   • Code scanning alerts
   • Dependabot alerts
   • Metadata (enabled by default)
5. Click Generate token and copy it

Step 2: Configure Claude Desktop

1. Open Claude Desktop
2. Go to Settings (gear icon) > Developer > Edit Config
3. This opens claude_desktop_config.json. Add the projectpulse entry inside "mcpServers":

{
  "mcpServers": {
    "projectpulse": {
      "command": "npx",
      "args": ["-y", "projectpulse-mcp"],
      "env": {
        "GITHUB_TOKEN": "ghp_paste_your_token_here"
      }
    }
  }
}

4. Save the file and restart Claude Desktop

Step 3: Verify it works

In a new Claude Desktop conversation, try asking:

"Check the health score of facebook/react"

Claude should call the get_health_score tool and return an A-F grade with a detailed breakdown.

Troubleshooting

Problem	Solution
Tools not showing up	Restart Claude Desktop after editing the config file
"Rate limit exceeded" errors	Make sure GITHUB_TOKEN is set correctly in the config
Dependabot/CodeQL data missing	Your token needs Code scanning alerts and Dependabot alerts permissions
npx not found	Install Node.js (v18 or later) and make sure npx is in your PATH

Other MCP Clients (Cursor, Windsurf, etc.)

Configure a new MCP server with:

• Transport: stdio
• Command: npx
• Arguments: -y projectpulse-mcp
• Environment: GITHUB_TOKEN = your GitHub PAT

🛠️ Tools

get_health_score

Calculates a 0-100 health score with an A-F grade. Evaluates 5 weighted categories: CI reliability (25%), code freshness (20%), security posture (25%), community activity (15%), and maintenance quality (15%). Returns actionable improvement suggestions for low-scoring categories. On repeated calls for the same repo, includes a trend comparison showing score change since last check. Queries multiple GitHub API endpoints and OpenSSF Scorecard.

Side effect: saves a trend snapshot to local disk (~/.projectpulse/snapshots/).

Inputs: owner, repo Try asking: "What's the health score of microsoft/vscode?"

get_dora_metrics

Calculates proxy DORA metrics from public GitHub data: Deployment Frequency (from releases), Lead Time for Changes (PR created → merged), Change Failure Rate (CI failure percentage), and Mean Time to Recovery (CI failure → next success). Returns null for metrics with insufficient data. Queries multiple GitHub API endpoints (releases, pulls, actions) — heavier API usage than single-endpoint tools.

Inputs: owner, repo, days (optional, 7-90, default 30) Try asking: "Show me the DORA metrics for vercel/next.js over the last 60 days"

compare_repos

Compares health scores side-by-side for 2-5 repositories. Returns each repo's full health breakdown ranked by score. Useful for evaluating alternatives or benchmarking your project against similar ones. API calls are multiplied by the number of repos compared.

Inputs: repos (array of {owner, repo}) Try asking: "Compare the health of expressjs/express, fastify/fastify, and koajs/koa"

get_repo_health

Fetches basic repository metadata: stars, forks, open issues count, primary language, license, last push date, default branch, and archive status. Use this for a quick overview — for a computed grade, use get_health_score instead.

Inputs: owner, repo Try asking: "Give me general info about torvalds/linux"

analyze_dependencies

Lists Dependabot security alerts for vulnerable package dependencies (npm, pip, Maven, etc.) grouped by severity (critical, high, medium, low). Optionally filter by a specific severity level. Requires a token with Dependabot alerts permission.

Inputs: owner, repo, severity (optional) Try asking: "Show me critical dependency vulnerabilities in my-org/my-app"

check_ci_status

Returns the most recent CI/CD workflow runs from GitHub Actions: status (success, failure, in_progress), conclusion, branch, duration, and timestamps. Useful for checking if builds are green before deploying or merging.

Inputs: owner, repo, limit (optional, default 10) Try asking: "Are the CI builds passing for facebook/react?"

analyze_code_scanning

Lists CodeQL and other code scanning alerts: rule ID, severity, vulnerability message, affected file and line number, and creation date. Requires a token with Code scanning alerts permission. Can optionally trigger a CodeQL scan and wait for results (requires Advanced Setup, not Default Setup).

Inputs: owner, repo, trigger_scan (optional, default false), poll_timeout_seconds (optional, default 300), poll_interval_seconds (optional, default 15) Try asking: "Are there any code scanning vulnerabilities in my-org/my-api?"

ping

Simple connectivity check. Returns "pong" with your message. Use to verify the MCP server is running.

Inputs: message

🆕 What's New

HTTP Transport (v1.7.0)

ProjectPulse now supports Streamable HTTP transport in addition to stdio. This enables running as a standalone HTTP server — ideal for Docker containers, remote deployments, and cross-runtime integrations (e.g., .NET clients consuming Node.js MCP tools over the network).

Default behavior is unchanged — npx projectpulse-mcp still uses stdio. To activate HTTP mode:

MCP_TRANSPORT=http MCP_PORT=3000 node dist/index.js

Env Variable	Default	Description
MCP_TRANSPORT	stdio	Transport mode: stdio or http
MCP_PORT	3000	HTTP server port (only used when MCP_TRANSPORT=http)

Docker example:

projectpulse:
  image: node:22-slim
  command: >-
    sh -c "npm install -g projectpulse-mcp &&
           node /usr/local/lib/node_modules/projectpulse-mcp/dist/index.js"
  environment:
    - MCP_TRANSPORT=http
    - MCP_PORT=3000
    - GITHUB_TOKEN=${GITHUB_TOKEN}

Health check endpoint available at GET / (returns JSON with server name and version). MCP protocol endpoint at POST /mcp.

OpenSSF Scorecard Integration

Security score now blends Dependabot alerts (60%) with OpenSSF Scorecard checks (40%) for a more complete picture. 12 security-relevant checks are evaluated — repos without a scorecard gracefully fall back to Dependabot-only scoring.

DORA Metrics

New get_dora_metrics tool calculates proxy DORA metrics from public GitHub data:

Metric	Source	Unit
Deployment Frequency	Releases	releases/week
Lead Time for Changes	PR created → merged	hours (median)
Change Failure Rate	CI workflow conclusions	percentage
Mean Time to Recovery	CI failure → next success	hours (median)

Metrics return null when insufficient data is available — works safely on any repository.

⚙️ Configuration

GITHUB_TOKEN

Required to avoid rate limits and access security data (Dependabot, CodeQL alerts).

Option A: Fine-grained PAT (Recommended)

1. Settings > Developer settings > Personal access tokens > Fine-grained tokens
2. Select target repositories
3. Grant Read-only access to:
   • Code scanning alerts
   • Dependabot alerts
   • Metadata (default)

Option B: Classic Token Generate with repo + security_events scopes.

Providing the token:

• Claude Desktop: set in claude_desktop_config.json (see Quick Start)
• Claude Code / Local: create a .env file:

  GITHUB_TOKEN=ghp_your_token_here
