Proof of Commitment

Stars lie. Behavioral signals don't.

An MCP server and web tool that scores npm packages, PyPI packages, Rust crates, Go modules, and GitHub repos on behavioral commitment — signals that are harder to fake than stars, READMEs, or download counts.

The supply chain problem

26 of the 91 npm packages with >10M weekly downloads have a single npm publisher. Together they account for over 3 billion downloads per week. npm audit doesn't surface this. Stars don't either.

Four packages in a typical Node.js project are CRITICAL right now:

• chalk — 413M downloads/week, 1 npm publisher
• zod — 163M downloads/week, 1 npm publisher (30+ GitHub contributors)
• lodash — 145M downloads/week, 1 npm publisher
• axios — 99M downloads/week, 1 npm publisher (attacked March 30, 2026)

They won't appear in your package.json either — but these are in almost every project:

• minimatch — 562M downloads/week, 1 npm publisher
• glob — 333M downloads/week, 1 npm publisher
• cross-spawn — 190M downloads/week, 1 npm publisher

Behavioral signals surface this. Stars and READMEs don't.

Quick install (MCP)

No login required. Add to any MCP-compatible AI tool and start querying supply chain risk.

Claude Desktop

Open ~/Library/Application Support/Claude/claude_desktop_config.json on macOS (config file reference) or %APPDATA%\Claude\claude_desktop_config.json on Windows, then add:

{
  "mcpServers": {
    "commit": {
      "type": "streamable-http",
      "url": "https://poc-backend.amdal-dev.workers.dev/mcp"
    }
  }
}

Restart Claude Desktop. A tool icon appears in the chat input — ask it to audit your package.json.

Cursor

Open ~/.cursor/mcp.json (Cursor MCP docs) and add:

{
  "mcpServers": {
    "commit": {
      "type": "streamable-http",
      "url": "https://poc-backend.amdal-dev.workers.dev/mcp"
    }
  }
}

Try it now

Terminal (zero install):

# New in v1.8.0: zero-arg auto-detect — cd into any project, run once:
npx proof-of-commitment
# Picks the highest-coverage manifest in cwd (package-lock.json > yarn.lock >
# pnpm-lock.yaml > pnpm-workspace.yaml > package.json; requirements.txt;
# Cargo.toml; go.sum > go.mod). When multiple ecosystems are present, the
# file with the most recent mtime wins.

# Explicit package list still works:
npx proof-of-commitment axios zod chalk

# Or point at a specific file:
npx proof-of-commitment --file package.json
npx proof-of-commitment --file package-lock.json   # npm (transitive)
npx proof-of-commitment --file yarn.lock           # yarn
npx proof-of-commitment --file pnpm-lock.yaml      # pnpm
npx proof-of-commitment --file pnpm-workspace.yaml # pnpm monorepo
npx proof-of-commitment --pypi litellm langchain requests
npx proof-of-commitment --cargo serde tokio reqwest
npx proof-of-commitment --golang github.com/gin-gonic/gin golang.org/x/net
npx proof-of-commitment --file go.mod
npx proof-of-commitment --file go.sum              # full transitive Go set

# JSON output for downstream tools:
npx proof-of-commitment --file package-lock.json --json | jq '.criticalCount'

CI integration (v1.8.0+)

--fail-on=<level> turns the CLI into a one-line CI gate. No GitHub Action required.
