"npm" matching MCP servers:

Model Context Protocol server for npm registry. Enables searching packages, checking security, comparing versions, and validating compatibility.

Enables AI assistants to track weekly npm package download trends, growth rates, and rankings for market and developer ecosystem research.

A Model Context Protocol server that enables AI-powered analysis of NPM packages through multiple tools for security vulnerability scanning, dependency analysis, package comparison, and quality assessment.

Provides weekly download counts and trend data for npm packages, enabling comparison of adoption velocity across JavaScript libraries.

Read-only on-chain query surface for the AgentCivics civil registry on Sui — soulbound AI-agent identities, on-chain memories, reputation, refusal records. Hosted, no install, no keypair. For write tools (register, write_memory, record_refusal), install the npm package @agentcivics/mcp-server locally and supply your own keypair.

A Model Context Protocol server that provides AI coding agents with real, live, source-cited documentation for npm, PyPI, and Cargo packages, including READMEs, metadata, vulnerability checks, and package search.

AI-powered code assistant that provides advanced search and discovery capabilities across GitHub and NPM ecosystems, helping users understand code patterns, implementations, and connections between repositories.

MCP security firewall (stdio): vet advertised tool definitions through static-scan → threat-feed → origin → pinning before they reach the model. Zero npm runtime deps. No secrets.

A universal MCP aggregator toolkit that connects AI agents to multiple MCP servers through a single unified configuration. Features ready-made templates, cross-repo prompt workflows, and an npm package for zero-config installation.

Translates a lockfile diff into a human-readable upgrade plan. For every dependency bump (npm or PyPI) returns semver class, breaking changes from GitHub release notes, CVEs fixed in the range, migration guide links, and a clear per-package recommendation. Bulk tool ranks up to 50 package changes in parallel by risk (security > caution > review > likely-safe > safe).

Provides npm/PyPI package intelligence including health scores, vulnerabilities, dependency graphs, and download counts via an MCP server, with optional pay-per-call access over x402 for advanced health and batch endpoints.

Godot 4 MCP server with: Test running (GUT/GdUnit4) with structured pass/fail results API docs search with 30+ Godot 3→4 migration mappings Script analysis detecting 10 common GDScript pitfalls Scene/resource file parsing with antipattern detection Viewport screenshot capture LSP diagnostics from Godot's language server TypeScript, cross-platform (macOS/Windows/Linux), published on npm

Enables LLMs to generate safe, accessible scroll-driven web animations by translating natural language requests into validated JSON specs, then compiling them into GSAP or WAAPI/CSS code with built-in reduced-motion and pause controls.

Enables U.S. exclusion, debarment, and license screening for agents, returning results with Ed25519-signed receipts of which list snapshots were checked.

Verifies which domain officially belongs to a software product, AI tool, or company, so the agent stops handing users lookalike download sites. Ownership only, never safety. Every verdict is backed by reproducible evidence; results carry the sentence the agent should say. Tools: get_official_url(name), verify_url(url). npm: @realurls/mcp; remote endpoint: https://api.realurls.org/mcp

Hashlock Markets (hashlock.markets) — sealed-bid intent-based crypto trading protocol with HTLC atomic settlement. AI agents can create, commit, and validate trading intents on Ethereum, Bitcoin, and Sui. Canonical npm package: @hashlock-tech/mcp. Not the cryptographic hashlock primitive, not Hashlock Pty Ltd (hashlock.com).

Tenant-bound MCP server for agent spend authorization, policy guardrails, evidence, escrow settlement, and portable receipts. Works with Cursor and Claude Code via stdio; npm (@paybond/kit) and Python (paybond-kit).

Pre-build reality check for AI coding agents — searches 5 real databases (GitHub, Hacker News, npm, PyPI, Product Hunt) to check whether an idea already exists before you build it.

The only MCP server that gives AI agents native access to Stacks, Celo, and Base — from a single npm package.

MCP server that recommends which npm/PyPI libraries to use or avoid, with concise verdicts, alternatives, and code snippets, keeping responses under 500 tokens.
