MCP Servers: 64 verified servers, 24 of which need no authentication, last checked 2026-09-24. Each entry carries a copy-paste install command and its transport.
Model Context Protocol servers are how an agent reaches the outside world — files, databases, browsers, tickets, payments. The official registry lists what exists; this page tells you what each server actually needs before you run it: the install command, the transport, and whether it wants a token, a connection string or nothing at all.
The signal most directories miss is maintenance. Several widely-recommended servers (Postgres, Slack, Puppeteer, Brave Search) were archived during 2025–2026 and are still recommended all over the web. They are listed here as deprecated, each paired with the maintained server that replaced it.
Start with the reference servers and Context7 if you are new to MCP; if you already have a stack, filter to official servers and check the authentication column before granting an agent access to anything that matters.

Version-pinned, up-to-date documentation for thousands of libraries — the single highest-value server for coding agents.
npx -y @upstash/context7-mcp✅ no authcommunity
Works without a key at low volume; an API key raises the rate limit. The most-installed MCP server on npm.
Drives a real Chrome instance for performance traces, console errors and network inspection.
npx -y chrome-devtools-mcp@latest✅ no authofficial
Browser automation over accessibility snapshots rather than screenshots — deterministic agent browsing in Chromium, Firefox and WebKit.
npx -y @playwright/mcp@latest✅ no authofficial
Accessibility-tree snapshots use far fewer tokens than screenshot-based browser agents.
Repo automation, PRs, issues, code search and CI workflows — the most-starred MCP server in the ecosystem.
docker run -i --rm -e GITHUB_PERSONAL_ACCESS_TOKEN ghcr.io/github/github-mcp-server🔑 GitHub PAT (fine-grained, read-only works)official
A hosted remote variant is available at https://api.githubcopilot.com/mcp/ if you would rather not run Docker.
Pythonic framework and CLI for building MCP servers in about ten lines, with a built-in dev inspector.
uvx fastmcp run server.py✅ no authcommunity

Pulls design tokens, layout and component structure out of Figma files into the editor, over stdio, using a personal access token.
npx -y figma-developer-mcp --figma-api-key=<token>🔑 Figma personal access tokencommunity
Renamed from 'Figma MCP' to name its maintainer: this is the community Framelink server, not Figma's own. For the first-party server see figma-mcp-server.
Works over stdio with a personal access token, so it needs no OAuth dance and no Figma desktop app — which is why people still reach for it over the official remote server.
Official suite covering S3, Lambda, DynamoDB, CloudWatch and 20+ other services.
uvx awslabs.core-mcp-server@latest🔑 AWS IAM credentials / SSO profileofficial
Scope IAM to a read-only role before letting an agent near your account.

Read-only-safe Postgres access with index tuning and health checks — the maintained replacement for the archived reference server.
uvx postgres-mcp --access-mode=restricted🔑 Postgres connection stringcommunity
The original @modelcontextprotocol/server-postgres reference server was archived in 2025 — many guides still tell you to install it.
Gmail, Drive, Calendar, Docs and Sheets through a single OAuth'd server.
uvx workspace-mcp🔑 Google OAuth 2.0community
Postgres schema, migrations, edge functions and logs through one authenticated server.
npx -y @supabase/mcp-server-supabase@latest --read-only --project-ref=<ref>🔑 Supabase personal access tokenofficial

Search, extract and map endpoints purpose-built for LLM grounding, with a genuinely usable free tier.
npx -y tavily-mcp@latest🔑 Tavily API key (1,000 free credits/month)official
Figma's own MCP server, hosted at mcp.figma.com over Streamable HTTP. Reads a selected frame's variables, components and layout into the editor, generates code from it, reuses real components through Code Connect and, while in beta, writes native content back to the canvas.
claude mcp add --transport http figma https://mcp.figma.com/mcp🔑 Figma account (OAuth)official
A hosted remote server rather than a package: https://mcp.figma.com/mcp answers 401 without a token, so there is nothing to install — you add the URL and authenticate.
Free to connect on Figma's free Starter plan, but that plan and View or Collab seats on paid plans are capped at 6 tool calls per month. Dev and Full seats on paid plans get Tier 1 REST API limits instead. This is a real free allowance, not a generous one — the Studio plan at $16/month is what most people will need for daily use.
Writing to the canvas is free during the beta, and Figma has said it will become a usage-based paid feature. Assume it will not stay free.
Also installable as Claude Code and Cursor plugins and as a Gemini CLI extension, which bundle the server config together with the Figma skill pack below.
Read customers, invoices and subscriptions, and create payment links from a prompt.
npx -y @stripe/mcp --tools=all --api-key=<rk_live_or_test>🔑 Stripe restricted API keyofficial

kubectl-style cluster operations — inspect pods, apply manifests and read logs.
npx -y mcp-server-kubernetes🔑 kubeconfig contextcommunity

docker mcp gateway run✅ no authofficial
Text-to-speech generation and voice management inside the agent loop.
uvx elevenlabs-mcp🔑 ElevenLabs API keyofficial

uvx mcp-server-qdrant --qdrant-url <url>🔑 Qdrant API key (cloud)official
Pairs with Qdrant's free 1GB cluster, so long-term agent memory costs nothing to start.
Provider and module registry lookups plus plan/apply assistance for infrastructure as code.
docker run -i --rm hashicorp/terraform-mcp-server✅ no authofficial
Keyless web search and safe text fetching — zero signup, which is rare in search tooling.
uvx duckduckgo-mcp-server✅ no authcommunity
Rate-limited by DuckDuckGo itself; fine for occasional lookups, not for bulk crawling.
Independent web and local search index with a free API tier — no Google/Bing dependency.
npx -y @brave/brave-search-mcp-server🔑 Brave Search API keyofficial
Brave's free tier is rate-limited to roughly one query per second and requires a card for verification.

No longer free — kept so you do not waste a signup.
The original browser-automation reference server. Superseded by Playwright MCP.
npx -y @modelcontextprotocol/server-puppeteer✅ no authofficial

npx -y @zencoderai/slack-mcp-server🔑 Slack bot/user tokencommunity
The original Slack reference server was archived in 2026 and now lives in modelcontextprotocol/servers-archived.
Semantic and keyword search over Wikidata's ~30M entities and properties, so agents can resolve vague concepts into verifiable QIDs before writing SPARQL.
npx -y mcp-remote https://wd-mcp.wmcloud.org/mcp/✅ no authofficial
Hosted as a public instance by Wikimedia Deutschland, so there is nothing to install or pay for. Exposes vector_search_items, keyword_search_items and vector_search_properties. Endpoint rejects plain GETs (406) by design — point an MCP client at it rather than curl.
Secure local file operations with configurable allow-listed directories — the reference server every local agent starts with.
npx -y @modelcontextprotocol/server-filesystem /path/to/allowed/dir✅ no authofficial
Always pass an explicit allow-listed root. Running it on `/` gives an agent write access to your whole machine.
Fetches a URL and converts it to clean markdown for the model, with robots.txt respect and chunked reading.

Turns any OpenAPI/Swagger spec into MCP tools — the fastest path to exposing an existing REST API.
npx -y @ivotoby/openapi-mcp-server --api-base-url <url> --openapi-spec <path>🔑 Target API credentialscommunity
An MCP server is a small program that exposes tools to an AI assistant through the Model Context Protocol, an open standard originally published by Anthropic. Instead of building a bespoke integration per client, a server declares its tools once and every MCP-capable client — Claude Code, Cursor, VS Code, Codex — can use them.
64 MCP servers are catalogued as of 2026-09-24, of which 49 are maintained by the company whose service they connect to and 24 need no authentication at all. Each entry carries a copy-paste install command and its transport type.
24 of the 64 servers here run without a key because they operate on your own machine rather than a remote API — filesystem, git, fetch and similar local tools. Remote servers for hosted products necessarily require an account, and the catalogue says which requires what.
The servers themselves are free and mostly open source, because they are small adapters rather than services. What may cost money is the API behind them: a Slack or Stripe MCP server is free to install but acts on an account that has its own pricing. The catalogue keeps those two facts separate.
