We installed every MCP server we could find, ran them for real work, and ranked the fifteen that deliver the most value per minute of setup. Grouped by what you actually use them for.
How we ranked
Four criteria: (1) install friction, (2) reliability across models, (3) breadth of tools surfaced, (4) real usage in our own team. No paid placements here — see the Get featured page for how promoted listings are marked on the directory.
The top 15
1. Filesystem MCP
The one every agent needs. Sandboxed file read/write with explicit scope. Install takes 30 seconds.
2. GitHub MCP
Pull requests, issues, code search across your orgs. Official from GitHub. Best companion for review workflows.
3. Postgres MCP
Read-only SQL by default, schema introspection included. If your product has a database, this server lets Claude answer “what is the weekly signup trend” in seconds.
4. Playwright MCP
Full-fat browser automation. Microsoft-maintained. Pair it with a scraping agent to automate anything that lives behind a web UI.
5. Slack MCP
Post, read, react. Useful for daily stand-up automations and on-call triage.
6. Firecrawl MCP
Scrape any site, get LLM-ready markdown. Handles JS-rendered pages — the fallback for any research agent.
7. Notion MCP
Query pages, update databases. Kills the “sync my meeting notes to Notion” pain.
8. Memory MCP
Persistent knowledge graph that survives across conversations. Game-changer for long-running projects.
9. Supabase MCP
Postgres + Auth + Storage bundled. If your product runs on Supabase, this one reduces three MCP servers into one.
10. Stagehand MCP
Natural-language browser control. Say “log into GitHub and star this repo”; it just works.
11. Stripe MCP
Invoices, customers, payment intents — safely. Restricted keys per environment.
12. Exa MCP
Neural web search. Returns semantically relevant results instead of keyword matches.
13. Figma MCP
Export assets, generate code from frames, keep design tokens in sync with your codebase.
14. AWS MCP
S3, Lambda, CloudWatch, RDS. Ops triage without opening the console.
15. Discord MCP
Channels, messages, roles. If your community lives on Discord, an agent can take over moderation triage.
Quick install cheat-sheet
Add these to ~/Library/Application Support/Claude/claude_desktop_config.json (Mac) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
{
"mcpServers": {
"filesystem": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-filesystem", "/Users/you/projects"]
},
"github": {
"command": "docker",
"args": ["run", "-i", "--rm", "ghcr.io/github/github-mcp-server"],
"env": { "GITHUB_PERSONAL_ACCESS_TOKEN": "ghp_..." }
},
"postgres": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-postgres", "postgresql://..."]
}
}
}
Restart Claude Desktop — the hammer icon appears, tools show up, you are live.
Bottom line
Start with numbers 1, 2 and 3 on day one. Add the rest as your workflow demands. Full directory of 130+ servers if you need something niche.
