The open source package registry for MCP (Model Context Protocol) servers. Every bundle scanned, every install scored.
Open-source package registry for MCP (Model Context Protocol) servers with built-in security scanning, trust scoring (L1-L4), and CLI. Every bundle verified across 25 supply-chain controls.
mpak provides three things:
MCP is the open protocol that lets AI agents call external tools. An MCP server exposes capabilities (API calls, file access, database queries) that agents invoke at runtime. That means MCP servers get privileged access to AI agent execution environments. A compromised server means arbitrary code execution inside your workflow.
The MCP ecosystem has no standardized supply chain security. Servers are distributed as loose scripts, GitHub repos, npm packages, and Docker images with no consistent packaging and no verification of what they contain before they run. The official MCP Registry indexes thousands of servers but makes no claims about their safety.
Discovery is solved. Trust is not. mpak handles what comes after discovery: packaging, verification, distribution, and governance.
A bundle is a .mcpb file (a ZIP archive) that contains everything needed to run an MCP server:
my-server.mcpb
├── manifest.json # Metadata: name, version, server_type, how to run it
├── src/ # Server source code
└── deps/ # All dependencies, vendored
manifest.json is the required entry point. It declares the package name, version, server type (node, python, or binary), platform-specific run commands, and the tools/prompts/resources the server exposes. The schema is defined in packages/schemas.
Every bundle receives a trust score from the MTF scanner. The score has two parts: a level (L1 through L4) and a numeric score (0 to 100) representing how many controls passed within that level. See the full framework at mpaktrust.org.
In the CLI output, L3 87 means the bundle reached Level 3 and passed 87% of L3 controls.
Bundles are published through GitHub Actions, not the CLI. A GitHub Actions workflow calls POST /v1/bundles/announce with a GitHub OIDC token. The registry verifies the token, downloads the release artifact from GitHub, validates the SHA256 hash, stores the bundle, and triggers an MTF security scan. This design ensures every published bundle has a verifiable link back to a source repository and CI run.
Claiming lets a maintainer prove they own a package. To claim @scope/my-server, add a mpak.json file to your GitHub repo:
{
"name": "@scope/my-server",
"maintainers": ["your-github-username"]
}
Then call the claim endpoint. The registry verifies the file exists in your repo with matching metadata. Once claimed, only the claimer (or the repo owner) can publish new versions.
Install the CLI:
npm install -g @nimblebrain/mpak
Search for a bundle:
mpak search github
# NAME VERSION TRUST DESCRIPTION
# @anthropic/github-mcp 1.2.0 L3 87 GitHub API integration
# community/github-issues 2.0.1 L4 94 Issue management
Pull and run it:
mpak bundle run @anthropic/github-mcp
The CLI downloads the bundle from mpak.dev, extracts it to ~/.mpak/cache/, and starts the MCP server.
Add a server to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):
{
"mcpServers": {
"github": {
"command": "mpak",
"args": ["bundle", "run", "@anthropic/github-mcp"]
}
}
}
claude mcp add github -- mpak bundle run @anthropic/github-mcp
This is a monorepo managed with pnpm workspaces and Turborepo.

packages/schemasZod schemas and inferred TypeScript types for the MCPB manifest format, API responses, trust scores, and validation helpers. This is the source of truth for data shapes across the entire stack.
Key exports: BundleSchema, MpakJsonSchema, SearchParamsSchema, validation functions.
packages/sdk-typescriptTypeScript SDK for interacting with a mpak registry. Wraps the HTTP API with typed methods for searching, downloading, and inspecting bundles.
import { MpakClient } from "@nimblebrain/mpak-sdk";
const client = new MpakClient(); // defaults to https://mpak.dev
const results = await client.searchBundles("github");
const bundle = await client.getBundleDetails("@anthropic/github-mcp");
packages/cliThe mpak command-line tool. Built with Commander.js.
apps/registryThe registry API server. Fastify with Prisma ORM on PostgreSQL. Handles bundle storage, downloads, trust score tracking, and the MTF scanning pipeline.
API surface:
/v1/bundles/* - Native mpak API for bundle operations/v0.1/servers - MCP Registry spec compatibility (so MCP clients can discover bundles through the standard protocol)/app/* - Routes used by the web UI (auth, admin, package claiming, scan results)/health - Health check/docs - OpenAPI/Swagger documentationStorage backends: Local filesystem, S3, GCS, Azure Blob Storage. Configured via environment variables.
Auth: Clerk (OIDC). Optional for read endpoints, required for publish.
apps/webReact SPA for browsing the registry. Built with Vite, Tailwind CSS 4, React Router, and TanStack Query. Includes trust score visualization, bundle details, and an admin panel.
apps/scannerPython security scanner implementing the mpak Trust Framework (MTF). Evaluates bundles against 20+ controls across five domains:
Produces a trust score from L1 (Basic) to L4 (Attested) based on which controls pass. See Trust levels for details on each level.
How scanning works: When a bundle is published, the registry creates a Kubernetes Job that runs the scanner image. The scanner evaluates the bundle, writes results to S3, and POSTs the score back to the registry via a callback URL. In Docker Compose, the scanner runs as a standalone container instead of a K8s Job.
pnpm install
If you already have PostgreSQL running locally:
psql -c "CREATE USER mpak WITH PASSWORD 'mpak' CREATEDB;"
psql -c "CREATE DATABASE mpak OWNER mpak;"
Or start one with Docker:
docker run -d --name mpak-postgres \
-e POSTGRES_USER=mpak -e POSTGRES_PASSWORD=mpak -e POSTGRES_DB=mpak \
-p 5432:5432 postgres:16-alpine
Each app that needs configuration has its own .env.example. Copy them:
cp apps/registry/.env.example apps/registry/.env
cp apps/web/.env.example apps/web/.env
The defaults work for local development with no changes needed.
cd apps/registry && npx prisma migrate dev && cd ../..
Populate the database with example bundles so the UI has something to show:
cd apps/registry && npm run db:seed && cd ../..
This inserts a handful of example bundles with multiple versions, download counts, and trust scores. Safe to run multiple times (uses upserts).
To add more seed data, edit apps/registry/prisma/seed.ts.
pnpm build
Start services individually. Each runs in its own terminal:
# Registry API (port 3200)
pnpm --filter @nimblebrain/mpak-registry dev
# Web UI (port 5173)
pnpm --filter @nimblebrain/mpak-web dev
# Docs site (port 4321)
pnpm --filter mpak-docs dev
Verify the registry is running:
curl http://localhost:3200/health
docker compose -f deploy/docker/docker-compose.yml up --build
# All TypeScript tests
pnpm test
# Specific package
pnpm --filter @nimblebrain/mpak-schemas test
pnpm --filter @nimblebrain/mpak-sdk test
pnpm --filter @nimblebrain/mpak test # CLI
# Python scanner tests
cd apps/scanner && uv sync --dev && uv run pytest
# Full verification (typecheck, lint, format check, tests)
pnpm verify
# Build all packages (respects dependency order via Turborepo)
pnpm build
# Build a specific package
pnpm --filter @nimblebrain/mpak-schemas build
# CLI smoke test after building
node packages/cli/dist/index.js --help
Each app manages its own .env file. There is no root .env.
apps/registry/.envSee apps/registry/.env.example for the full list. Key variables:
apps/web/.envSee apps/web/.env.example for the full list.
Run Prisma migrations directly:
# Check migration status
cd apps/registry && DATABASE_URL="postgresql://..." npx prisma migrate status
# Run pending migrations
cd apps/registry && DATABASE_URL="postgresql://..." npx prisma migrate deploy
helm lint deploy/kubernetes/helm/mpak/
helm install mpak deploy/kubernetes/helm/mpak/ \
--set config.databaseUrl="postgresql://..." \
--set config.storageBackend=s3
The Helm chart supports existingSecret for production secrets management.
docker compose -f deploy/docker/docker-compose.prod.yml up -d
Uses pre-built images with S3 storage and proper resource limits.

The CLI and web UI both talk to the registry API. The registry stores bundles in configurable storage (S3, GCS, Azure, or local filesystem) and metadata in PostgreSQL. Bundles are published via GitHub Actions OIDC (not the CLI). When a bundle is published, the registry creates a Kubernetes Job running the scanner. The scanner evaluates MTF controls, writes detailed results to S3, and POSTs the trust score back to the registry via a callback URL.
