"npm" matching MCP servers:

A secure Node.js execution environment that allows coding agents and LLMs to run JavaScript dynamically, install NPM packages, and retrieve results while adhering to the Model Control Protocol.

A meta-server that allows Claude to install other MCP servers from npm or PyPi, enabling easy expansion of Claude's capabilities with external tools.

A lightweight and extendable MCP server toolkit that allows developers to build and integrate custom tools with AI assistants through automatic tool discovery from local directories or npm packages.

Agents need a public place to register, post, and coordinate without a human creating accounts for each bot. This MCP server is that interface: machine-readable onboarding, live tools, and links to npm/Smithery so runtimes can find and use LuisCore automatically.

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.

Official SQAI MCP server: governed structured data access powered by Mojo kernels. 3 stdio tools: listSources (discovery), queryData (deterministic read-only queries + compute with provenance), explainQuery (dry-run validation). Introspection needs no credentials; execution requires a one-time free sqai login. npm: @thyn-ai/sqai-mcp. Source: packages/mcp. Registry: io.github.thyn-ai/sqai.

The artifact store for AI agents. Every output your agents produce — persisted, retrievable, shareable. Across runs, sessions, and tools. Session/agent metadata, content-hash dedup, and expiring share links; available on npm (@artifacta-mcp/mcp) and PyPI (artifacta-mcp).

Know-your-agent backed by ICP-Brasil: a company (e-CNPJ) or a person (e-CPF) signs that an AI agent acts for them, within a mandate. Signed credentials and verdicts, CRL checks, MCP + HTTP with x402, and an npm library to verify or issue without a hosted service.

Hosted MCP for MeetMyAgent: set up and manage a business AI agent that answers customer questions on your website and dedicated page. Connect at https://meetmyagent.io/mcp with OAuth. The old npm client is retired.

Enables autonomous project management with intelligent synchronization between GitHub, Notion, and Motion, including pattern recognition, self-optimization, and automated field population.

Persistent memory, teams, and projects for AI agents. 76 MCP tools for storing, recalling, and sharing knowledge across sessions with 4-strategy hybrid search.

It enables AI coding agents to persist local scripts as callable MCP tools with JSON Schemas, execute them via subprocess, and expose new tools immediately without restarting. This reduces token and latency costs for repetitive multi-step file, data, and batch operations.

Enables MCP clients to control a Minecraft survival character via Mineflayer, with a web UI, viewer, and custom TypeScript script execution.

Provides AI coding agents with a secure, sandboxed environment for executing coding tasks including file operations, command execution, and testing. Features session management, policy enforcement, and Docker-based sandboxing for safe code execution and development workflows.

Enables AI assistants to manage the product management workflow—turning meeting recordings into prototypes, PRDs, and review records through a 53-tool agent with six-stage SOP and self-evolving skills.
