Context7

Pulls current, version-specific library docs and code examples into your agent's context

Run the setup CLI

npx ctx7 setup

Copied from the project's docs at github.com/upstash/context7

Why you'd want it

Context7 targets outdated training data and hallucinated APIs by fetching documentation and code examples for the library and version you name in the prompt. Its MCP server has two tools: resolve-library-id maps a library name to a Context7 ID, and query-docs returns docs relevant to a question. It can also run without MCP as the ctx7 CLI plus an agent skill, and npx ctx7 setup configures either mode for Cursor, Claude Code or OpenCode.

Best for

  • Coding agents working with fast-moving libraries
  • Pinning answers to a specific library version
  • Cursor and Claude Code users

Use it when

Your agent keeps writing code against outdated or nonexistent APIs for the libraries you depend on.

Skip it if

You need a fully self-hosted setup: only the MCP server and CLI are in the repo, and requests go to the hosted Context7 API, with low rate limits unless you add an API key. Library docs are community-contributed and Context7 does not guarantee their accuracy.

    Use it when, skip it if, stats for GitHub MCP Server

    Why you'd want it

    GitHub's official MCP server lets an agent browse and search code, manage issues and pull requests, monitor Actions runs and review code scanning and Dependabot alerts. GitHub hosts a remote version at api.githubcopilot.com/mcp with OAuth or personal access token auth, and the same server runs locally from a Docker image or a Go binary. Tools are grouped into toolsets you can enable selectively, and a read-only mode removes every tool that makes changes.

    Best for

    • Agents that triage issues or review pull requests
    • Investigating CI failures from the editor
    • Teams that want a hosted server with OAuth

    Use it when

    Your agent needs to read or act on GitHub repositories, issues, pull requests or workflows as part of its task.

    Skip it if

    You do not use GitHub. Remote OAuth depends on each host configuring a GitHub App or OAuth App, so some clients need a personal access token, and GitHub Enterprise Server needs extra setup.

    Playwright MCP

    MCP server

    Lets an agent drive a real browser with Playwright using accessibility snapshots, not screenshots

    • v0.0.83 on

    Add to Claude Code

    claude mcp add playwright npx @playwright/mcp@latest
    Use it when, skip it if, stats for Playwright MCP

    Why you'd want it

    Microsoft's MCP server exposes Playwright browser automation as tools that act on structured accessibility snapshots, so no vision model is needed and actions avoid the ambiguity of screenshot-based clicking. It runs Chrome, Firefox, WebKit or Edge, headed or headless, can attach to your logged-in browser through the Playwright extension, and has opt-in capabilities for network, storage, DevTools, PDF, vision and test assertions. The README positions MCP for long-running loops that need persistent browser state, and points coding agents to the more token-efficient Playwright CLI with skills.

    Best for

    • Exploratory web automation by agents
    • Self-healing tests and long-running browser workflows
    • MCP clients without built-in browser control

    Use it when

    Your agent needs to navigate, fill forms and inspect pages across many steps while keeping the same browser session.

    Skip it if

    You use a coding agent and care about context size; Microsoft suggests Playwright CLI with skills for that. It is not a security boundary, so keep it away from sessions or data you would not hand to the model.

    Exa MCP Server

    MCP server

    Gives agents Exa web search and page fetching as MCP tools, with optional multi-step research runs

    • MIT

    Install the Claude Code plugin

    claude plugin install exa@claude-plugins-official
    Use it when, skip it if, stats for Exa MCP Server

    Why you'd want it

    Exa hosts the server at mcp.exa.ai/mcp and it works without an API key under rate limits, so setup is a URL or a plugin install. The default tools are web_search_exa, which returns clean content for search results, and web_fetch_exa, which reads pages as markdown; advanced search with domain and date filters and Exa Agent runs for multi-step research can be turned on with the tools URL parameter. The repo also ships search and exa-agent skills that load with plugin installs.

    Best for

    • Coding agents that need current web results
    • Multi-step research and list-building
    • Improving built-in web search in Claude, ChatGPT or Codex

    Use it when

    Your agent needs to search the web or read pages as clean markdown and you want a hosted server with nothing to install.

    Skip it if

    You need more than light anonymous use: the keyless server is rate-limited, and Exa Agent requires OAuth or an Exa API key.
