Plugins, MCPs, CLI tools
IDE plugins, concrete MCP servers, and CLI tools that give agents tools and context.
| # | Project | Stars | Tier | OSS | Description |
|---|---|---|---|---|---|
| 1 | MCP Servers mcpmemorytypescript | 89.1k | mostly simple | ✅ | The official reference collection of Model Context Protocol servers (filesystem, git, fetch, memory, time, and more)—the canonical, vetted toolset agents connect to, and the pattern every other MCP server is measured against. |
| 2 | Context7 mcptrainingtypescript | 60.2k | super simple | ✅ | MCP server that injects up-to-date, version-specific library docs into an agent's context on demand; kills the stale-training-data hallucinations that plague codegen. |
| 3 | chrome-devtools-mcp mcpbrowsertypescript | 48.4k | mostly simple | ❓ | Google's official Chrome DevTools MCP server: exposes console, network, and performance-trace inspection as tool calls agents can drive directly, instead of a human clicking through the DevTools panel. |
| 4 | aider mcpclipython | 47.9k | slightly complex | ✅ | Git-aware CLI pair programmer; edits in-repo, supports multiple models and MCP so agents see version control and tools. |
| 5 | Playwright MCP mcpvisionbrowsertypescript | 35.7k | mostly simple | ✅ | Playwright's official MCP server: structured browser control (navigate, click, fill, extract) via the accessibility tree rather than screenshots, so web tasks stay fast and deterministic. |
| 6 | continue idetypescript | 35.3k | complex | ✅ | Open-source IDE extension (VS Code, JetBrains); in-editor completion and chat with local or API models. |
| 7 | github-mcp-server mcp | 31.9k | slightly complex | ✅ | GitHub's official MCP server (Go): repos, issues, PRs, code search, Actions. Replaces the older community `cyanheads/github-mcp-server` as the canonical way to give agents GitHub access. |
| 8 | MCP Python SDK mcppython | 23.8k | mostly simple | ✅ | Official SDK to build and consume MCP servers/clients in Python; stdio and SSE transports. |
| 9 | MCP TypeScript SDK mcptypescript | 13k | mostly simple | ✅ | Official MCP implementation for Node/TS; reference for the protocol. |
| 10 | MCP Inspector mcptypescript | 10.6k | super simple | ✅ | GUI to test and debug MCP servers; inspect tools, resources, and prompts. |
| 11 | MCP Registry mcp | 7.1k | slightly complex | ✅ | Official, community-driven registry for MCP servers—the "app store" MCP clients use to discover servers. Maintained by Anthropic + ecosystem maintainers; v0.1 API frozen, production-grade. |
| 12 | Agent Governance Toolkit sandboxpython | 5.6k | slightly complex | ✅ | Microsoft's policy-enforcement layer for autonomous agents: zero-trust identity, execution sandboxing, and OWASP Agentic Top-10 coverage sit in front of the agent loop as a **harness** security layer—the governance counterpart to Infisical's agent-vault. |
| 13 | mcp-context-forge mcppython | 4.2k | complex | ❓ | IBM's official AI gateway/registry/proxy that sits in front of any MCP, A2A, or REST/gRPC API: unified endpoint, centralized discovery, guardrails, and plugin support—the enterprise front door for **harness** tool calling. Graduated off the radar this cycle. |
| 14 | cocoindex-code mcpcli | 2.6k | mostly simple | ❓ | Embedded, tree-sitter/AST-based code-search CLI and MCP server that gives coding agents fast semantic lookups over a repo instead of grepping or re-reading whole files into context. |
| 15 | agent-vault | 2k | mostly simple | ❓ | Infisical's HTTP credential proxy that fronts secrets for Claude Code, OpenClaw, and other agent harnesses so the agent's tool calls never see raw credentials—a **harness** security layer, not an agent loop itself. |
| 16 | Docker MCP Gateway mcpsandboxcli | 1.5k | slightly complex | ✅ | Docker's official MCP CLI plugin / gateway; container-aware MCP tooling from Docker (replaces deprecated `docker/mcp-servers` path). |
| 17 | puppeteer-real-browser-mcp mcpbrowsertypescript | 25 | mostly simple | ❓ | Puppeteer MCP with real-browser and anti-detection; for agents that need to drive sites that block headless. |
| 18 | Better-OpenCodeMCP mcptypescript | 9 | mostly simple | ✅ | MCP server for OpenCode/Crush: async task execution, model bridging (e.g. Claude→Gemini), process pooling. |
| 19 | agentlog memoryclipython | 1 | super simple | ✅ | Persistent decision memory for any project: `remember`, `recall`, `reflect`. Single-file Python CLI that stores decisions as JSONL and uses Claude or Gemini to retrieve and synthesize patterns—Karpathy's LLM Wiki concept as a CLI. |
