You don't have to build an MCP server yourself — you can find an already-published one and connect it to give Claude access to external tools and data. So where do you find trustworthy servers? This guide maps out the paths to find and choose MCP servers, from the Claude app's connector directory to the official MCP registry. (Official: modelcontextprotocol.io · as of June 2026)
Four ways to find servers
There are roughly four paths to find MCP servers. Whichever you take, they lead to the same ecosystem of servers.
- Connector directory — the list of connectors offered inside the Claude app. A few clicks to connect, easiest for non-developers.
- Official MCP registry — a standard list of public MCP servers, so you can see "what servers exist" in one place.
- GitHub reference implementations — a small set of example servers kept by the MCP maintainers, for education/reference.
- Marketplaces / curated sites — third-party sites that aggregate registry data and add ratings or categories.
What the official MCP registry is
The official MCP registry (registry.modelcontextprotocol.io) acts as a standard list of public MCP servers. Official docs compare it to "an app store for MCP servers." It launched in preview in September 2025 and is run as a community effort with contributors including Anthropic.
A key trait: the registry holds metadata only. The actual server code lives in existing package registries like npm, PyPI, and Docker Hub; the registry merely points to "which server is where."
Note it is in preview, so specs and data may change, and it does not cover private (internal-only) servers. Check the official docs for the current state.
The easiest path: the Claude app connector directory
If you're not a developer, the connector directory in the Claude app is fastest. You pick a connector from a list and connect it, without handling server addresses or config yourself. For step-by-step connection, see how to connect MCP.
Browse by purpose
Registries and directories usually let you browse servers by purpose. Common groupings include (for specific picks, see recommended MCP servers):
- Dev/code — repos, issues, deploy tools
- Search/web — web search, document gathering
- Files/docs — drive and document storage
- Databases — query and manage DBs
- Collaboration/messaging — calendar, chat, work tools
What to check when choosing
Servers access external tools and data, so choose carefully. Check:
- Maintainer — official or a trusted provider?
- Permissions — does it request only what's needed (least privilege)?
- Maintenance — is it actively updated?
- Source — is the code/install path public and verifiable?
Be especially careful with third-party servers' permissions and security, and use trusted sources only.
