Testing a remote server before use: Best Remote MCP Servers
Answer in brief
Connect the server's address in the MCP Inspector, read its tools and mark every one that writes.
The Inspector
The MCP Inspector is the reference tool for testing and debugging MCP servers. Run npx @modelcontextprotocol/inspector and connect the remote address to see every tool it offers.1
Tool descriptions are claims
The specification tells clients to treat tool annotations as untrusted unless the server is trusted, and says a person should always be able to deny a tool call.2
Mark the writes
List each tool that changes, sends or deletes something, and keep your client's approval on for those.

What should I verify first?
