MCP server directory
An MCP server gives an assistant tools: files, repositories, a browser, payments. Each listing says who maintains it, how to install it, and what it can read, write or spend.

Before you install one
A server runs with whatever access you give it, and anything it reads can carry instructions to your assistant. Four checks, drawn from the MCP specification and the servers' own READMEs.
- 1 Read the access line Writes data and Moves money mean a wrong tool call changes something real. Use a read-only mode where one exists: GitHub, Linear and Supabase each document one.
- 2 Scope the token Give each server its own token with the fewest permissions it needs. The MCP security guidance calls this scope minimization, and the GitHub server README asks for separate tokens per project.
- 3 Pin the version A local server runs with the same privileges as your client. Replace @latest with an exact version, such as @playwright/mcp@0.0.83 (latest on npm on 2026-10-15), so the code you reviewed is the code that runs.
- 4 Treat fetched text as untrusted The MCP tools specification says a human should be able to deny any tool call. Keep confirmations on: a web page, issue or support ticket can contain instructions aimed at your assistant.
Adding a server to your client
MCP, the Model Context Protocol, is an open standard for connecting AI applications to external systems. Most clients keep a JSON list of servers: a local server is the command that starts it, a remote server is a URL. VS Code names the top-level key servers; many other clients use mcpServers.
