1. Filesystem Server
What it does: Provides secure file operations with configurable access controls.
Why it's essential: The filesystem server is often the first MCP server people install. It allows AI applications to read, write, and manage files on your local machine — essential for any coding assistant.
Key Features:
Use Cases:
Link: GitHub - Filesystem Server
2. GitHub Server
What it does: Full GitHub integration including repository management, issues, and pull requests.
Why it matters: If you work with code, you work with GitHub. This server lets AI assistants manage your entire GitHub workflow.
Key Features:
Use Cases:
3. Slack Server
What it does: Channel management and messaging capabilities for Slack workspaces.
Why it's useful: Slack is where modern teams communicate. This server enables AI-powered Slack automation.
Key Features:
Use Cases:
4. PostgreSQL Server
What it does: Read-only database access with schema inspection.
Why it's valuable: Database access is crucial for data-driven AI applications. Query your data directly from your AI assistant.
Key Features:
Use Cases:
5. Google Drive Server
What it does: File access and search capabilities for Google Drive.
Why you need it: If your documents live in Google Drive, this server brings them to your AI assistant.
Key Features:
Use Cases:
6. Brave Search Server
What it does: Web and local search using Brave's Search API.
Why it's great: Give your AI the ability to search the web for current information.
Key Features:
Use Cases:
For the full walkthrough — API key, mcp.json config, free-tier limits, and the prompts that get the cleanest answers — see our Brave Search MCP server setup guide.
If you want a synthesized, cited answer instead of a results list, see the Perplexity MCP server setup guide. If your query is more "find things conceptually like X" than a precise keyword search, see the Exa MCP server setup guide for neural search instead.
7. Memory Server
What it does: Knowledge graph-based persistent memory system.
Why it's unique: This server gives AI applications persistent memory across sessions — remember conversations, preferences, and context.
Key Features:
Use Cases:
For the full Cursor IDE walkthrough — config, the tools table, and the MEMORY_FILE_PATH mistake that silently resets your memory — see our Memory MCP server setup guide.
8. Puppeteer Server
What it does: Browser automation and web scraping capabilities.
Why it's powerful: When you need AI to interact with web pages, Puppeteer server makes it possible. For the full Cursor IDE config — including the no-auth setup and where it differs from Playwright — see our Puppeteer MCP server setup guide.
Key Features:
Use Cases:
9. Sequential Thinking Server
What it does: Dynamic and reflective problem-solving through thought sequences.
Why it's interesting: This server helps AI break down complex problems into manageable steps.
Key Features:
Use Cases:
Full Cursor IDE setup, the tool's actual parameters, and where it's overkill versus genuinely useful: Sequential Thinking MCP server setup guide.
10. Fetch Server
What it does: Web content fetching and conversion for efficient LLM usage.
Why it's practical: Fetch and process web content in a format optimized for AI consumption.
Key Features:
Use Cases:
Complete Cursor IDE setup — uvx install, robots.txt behavior, and pagination for long pages — is in our Fetch MCP server setup guide.
Honorable Mentions
Notion Server: For those who live in Notion, this server brings your workspace to AI.
Sentry Server: Retrieve and analyze issues from Sentry for debugging assistance.
Time Server: Time and timezone conversion — simple but surprisingly useful.
Git Server: Read, search, and manipulate Git repositories directly.
n8n: Not a single-purpose server — n8n lets you expose your own multi-step workflows as MCP tools, so a chain of API calls and logic becomes one callable function instead of something the AI has to orchestrate itself. See the n8n MCP server setup guide.
How to Install MCP Servers
Most MCP servers can be installed via npm:
npm install -g @modelcontextprotocol/server-filesystem
Then add to your Claude Desktop config:
{
"mcpServers": {
"filesystem": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/allowed/dir"]
}
}
}
