This server focuses on providing structured JSON output for npm/pnpm operations, suitable for AI agent integration. It is not an official npm server but a community project. Its main strengths are token efficiency and reliability, but it requires Node.js 20+ and only supports npm/pnpm.
Strongest · Maintenance 12/20 Weakest · Reliability 6/20
Why each score
- Reliability 6/20
- Evidence is limited to the manifest and the general README. The manifest declares @paretools/npm 0.22.0 over stdio and describes structured install/audit/outdated/list/run operations, so a happy path is plausible. No source, tests, or CI workflow for packages/server-npm was supplied, so the init handshake and tool-to-behavior correspondence cannot be verified; deducted for missing execution evidence per static calibration.
- Security and permissions 7/20
- No red-line risks are evident. npm install/run involve network access and script execution, and audit contacts the registry, but the documentation does not show per-server confirmation, least-privilege, or command scoping, nor does it describe .npmrc credential handling. Main risks are visible but permission/confirmation evidence is incomplete.
- Maintenance 12/20
- The repository is not archived, the manifest shows version 0.22.0, an MIT license is present, and the README displays CI, Codecov and OpenSSF badges, indicating ongoing maintenance. However, no commit history, release notes, or security-response channel was provided, so governance and update-path evidence is incomplete.
- Documentation 9/20
- The README offers project-wide install, configuration, tool-filtering and troubleshooting guidance, but lacks packages/server-npm-specific tool parameters, output schemas, authentication, and limits; the linked tool-schema docs are not part of the supplied material, so deduction applies.
- Setup experience 10/20
- The README gives a quick-start flow, presets, client config examples and a Node.js >=20 requirement, making the overall installation path clear. A concrete MCP config example for the npm server is not shown (the example uses git), requiring inference, and no execution evidence supports a score above 15.

What it can accessReads local filesWrites / deletes local filesRuns commands or codeUses the network
Not for
- Simple manual commands not requiring structured output
- Projects that need package managers other than npm/pnpm (e.g., yarn, bun) since this server only supports npm/pnpm
- Beginners unfamiliar with the MCP protocol
Required permissions
- Needs access to package.json and lock files in the project directory
- Can execute npm/pnpm commands that may consume network resources (e.g., install, audit)
- Needs to read the project's dependency tree and configuration
Risks and side effects
- Running npm install may modify node_modules and lock files; back up important data
- npm audit may return a large amount of data, but structured output may still contain sensitive info like dependency versions
- The server communicates via stdout; misconfiguration can lead to protocol conflicts
Setup
Before you start
Runtime：Node.js 20+
Other optional settings (2)
PARE_NPM_TOOLS
Optional per-server filter limiting which tools the npm server registers, e.g. install,test,run; unset means all tools.
PARE_TOOLS
Optional universal filter across all Pare servers in server:tool comma-separated format, e.g. git:status,npm:install; takes precedence over per-server vars.
- Use npx @paretools/init --client <client> --preset web for quick setup.
- Or add @paretools/npm as an MCP server in your client config, e.g., using the command npx -y @paretools/npm, and set the PARE_NPM_TOOLS environment variable to specify desired tools.
Check that it works
Confirm the tools install, audit, outdated, list and run appear in the client's tool list, then ask the agent to run npm list — a structured JSON dependency listing proves the connection works.
Troubleshooting
- Ensure Node.js version >= 20 (Pare requirement)
- If using npx and encountering ENOENT, try 'cmd /c npx' or the absolute path
- First start may be slow; run 'npx -y @paretools/npm' ahead of time to cache
- If MCP connection times out, set MCP_TIMEOUT=30000 or increase initTimeout in client config
- Use PARE_NPM_TOOLS env var to limit tools and reduce context usage
Things to try
Once connected, you can ask your AI assistant things like:
- Install all dependencies from package.
- Check this project's dependencies for known security vulnerabilities
- Show me which dependencies have newer versions available
- Run the test script and summarize the results as JSON

Overview
Pare npm is an MCP server from the Pare project that provides structured, typed JSON output for npm/pnpm operations. It wraps common commands like install, audit, outdated, list, and run, converting raw terminal text into schema-validated JSON to avoid brittle string parsing. The server returns two outputs: content (human-readable text) and structuredContent (type-safe JSON) for agents to process directly. It reduces token consumption and improves reliability.
