Start with the official reference set.
The official examples cover different kinds of capability: filesystem access, Git operations, fetching content, memory, sequential reasoning, and time. They are useful because each one isolates a design problem instead of pretending that one server pattern fits every system.
Treat the examples as learning material, not a blanket trust list. Read the repository instructions, inspect the permissions, and run the server against safe data before connecting it to a production account or a client that can approve actions automatically.
Match examples to learning goals.
Use a read-oriented fetch or time example to learn discovery, schemas, and result handling. Use filesystem or Git examples to understand how a capability boundary changes when the server can inspect or modify local state. Use memory or reasoning examples to study context and multi-step interactions without confusing them with business authorization.
For each example, write down the input, output, side effect, credential, and recovery path. That small inventory turns a demo into a comparison that can guide your own server design.
- Read-only examples are a safer first connection.
- Filesystem and Git examples require explicit path and write boundaries.
- Context examples still need provenance and retention decisions.
Use the registry as a discovery layer, not a quality guarantee.
A registry can help readers find metadata and packages, but discoverability does not replace code review, source verification, or permission review. Check who maintains a server, which transport it uses, where its credentials go, and what its tools can do.
Keep an example list current. MCP documentation and registry behavior are evolving, so link to the current official source and label preview or experimental features rather than presenting them as permanent guarantees.
Turn an example into a bounded experiment.
Define one safe question, one test account or directory, one expected result, and one way to stop the process. Record the server version, client configuration, tool calls, and observed errors. Then decide whether the example is only educational or worth adapting into a maintained service.
The best example is not the one with the most tools. It is the one that makes the next boundary easy to explain and verify.
