MCP turns Claude from a chatbot into a power tool. Instead of copying data between tabs, you give Claude direct access to your files, APIs, browser, and databases. Here are the 7 servers that changed how I work.
Quick context: The Model Context Protocol (MCP) is an open standard that lets AI assistants connect to external tools through a unified interface. Think of each MCP server as a plugin that gives Claude a new superpower.
1. Filesystem — Let Claude Read and Edit Your Project Files
The official filesystem server gives Claude direct access to your local files. No more pasting code into the chat window. Claude can read your codebase, create files, move things around, and search across directories.
Install:
{
"mcpServers": {
"filesystem": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/your/project"]
}
}
}
Example use case: "Refactor all the error handling in my src/ directory to use a shared AppError class." Claude reads every file, identifies the pattern, and applies consistent changes.
Why it matters: This is the server most people install first, and for good reason. It removes the biggest bottleneck in AI-assisted coding — context transfer.
2. GitHub — Manage Repos, Issues, and PRs Without Leaving the Chat
The GitHub MCP server connects Claude to the GitHub API. You can ask Claude to check open PRs, create issues, review diffs, search across repos, and trigger workflows.
Install:
{
"mcpServers": {
"github": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-github"],
"env": {
"GITHUB_PERSONAL_ACCESS_TOKEN": "ghp_your_token_here"
}
}
}
}
Example use case: "Find all open issues labeled bug in my repo, group them by component, and draft a priority list." Claude pulls the data directly from GitHub and organizes it for you.
Why it matters: Stops the constant tab-switching between your editor and GitHub. Especially powerful for maintainers juggling multiple repos.
3. mcp-openapi — Connect Claude to Any REST API in 30 Seconds
If you work with REST APIs, this one saves a ridiculous amount of time. Point mcp-openapi at any OpenAPI or Swagger spec URL, and it automatically generates MCP tools for every endpoint. No code, no config files, no manual mapping.
Install:
{
"mcpServers": {
"petstore": {
"command": "npx",
"args": ["-y", "mcp-openapi"],
"env": {
"API_BASE_URL": "https://petstore3.swagger.io",
"OPENAPI_SPEC_URL": "https://petstore3.swagger.io/api/v3/openapi.json"
}
}
}
}
Example use case: "List all available pets, then add a new one named 'Claude' to the store." It just works — Claude discovers the endpoints from the spec and calls them.
Why it matters: Most APIs publish an OpenAPI spec. This server turns that spec into instant Claude tools. I automated testing across 3 different internal APIs in an afternoon using this approach.
4. Brave Search — Give Claude Access to the Live Web
Claude's training data has a cutoff date. Brave Search fixes that by letting Claude search the web in real time. It uses Brave's privacy-focused search API, so your queries stay private.
Install:
{
"mcpServers": {
"brave-search": {
"command": "npx",
"args": ["-y", "@brave/brave-search-mcp-server"],
"env": {
"BRAVE_API_KEY": "your_api_key_here"
}
}
}
}
You will need a free API key from Brave Search API.
Example use case: "What are the latest breaking changes in Next.js 15? Summarize the migration guide." Claude searches, reads the results, and gives you a current answer.
Why it matters: Research tasks that used to require 20 minutes of browsing now take one prompt. Particularly useful for staying on top of fast-moving frameworks and libraries.
5. graphql-to-mcp — Same Idea as #3, But for GraphQL
If your stack uses GraphQL instead of REST, graphql-to-mcp does the same thing — point it at a GraphQL endpoint, and it auto-discovers the schema via introspection and creates MCP tools for every query and mutation.
Install:
{
"mcpServers": {
"spacex": {
"command": "npx",
"args": ["-y", "graphql-to-mcp"],
"env": {
"GRAPHQL_ENDPOINT": "https://spacex-production.up.railway.app/graphql"
}
}
}
}
Example use case: "Query the SpaceX API for all launches in 2025 and tell me which rocket was used most." Claude introspects the schema, builds the query, and runs it.
Why it matters: GraphQL APIs are everywhere (GitHub, Shopify, Contentful, Hasura), and writing queries by hand is tedious. This server removes that friction entirely.
6. Memory (Knowledge Graph) — Give Claude Persistent Memory Across Chats
By default, every Claude conversation starts from zero. The Memory server changes that by storing entities and relationships in a local knowledge graph. Claude can remember your preferences, project context, and past decisions.
Install:
{
"mcpServers": {
"memory": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-memory"]
}
}
}
Example use case: "Remember that our production database is on AWS us-east-1, the staging branch is develop, and we deploy on Thursdays." Next conversation, Claude already knows.
Why it matters: The single biggest quality-of-life improvement for repeat users. No more re-explaining your project setup every session.
7. Playwright — Let Claude Control a Real Browser
The Playwright MCP server gives Claude the ability to navigate web pages, click buttons, fill forms, and extract data from any website. It uses accessibility snapshots instead of screenshots, which makes it fast and reliable.
Install:
{
"mcpServers": {
"playwright": {
"command": "npx",
"args": ["-y", "@playwright/mcp@latest"]
}
}
}
Example use case: "Go to our staging site, log in with test credentials, navigate to the dashboard, and verify the chart shows this month's data." Claude drives the browser step by step.
Why it matters: This unlocks automation for anything that does not have an API. Scraping, testing, form filling, screenshot comparisons — all from natural language.
How to Find More MCP Servers
These 7 are my daily drivers, but the ecosystem is growing fast. Here are the best places to discover new servers:
- Official MCP Registry — The canonical source, maintained by the MCP project
- mcp.so — Community-curated directory with search and categories
- Smithery — Browse, install, and manage MCP servers with a clean UI
- awesome-mcp-servers — The GitHub awesome list (83K+ stars)
Over to You
These 7 servers cover files, APIs, search, memory, and browser automation — which handles about 90% of what I throw at Claude daily.
