An MCP server checklist before you connect real accounts
Review an MCP server's identity, exposed tools, account permissions, deployment model and failure behavior before using production credentials.
An MCP listing tells you that a project offers a way to connect an AI application to tools or data. It does not establish who operates the server, what a credential permits, or how your host handles approval. Use this source-reviewed checklist to prepare a narrow trial. The proposed trial is our guidance, not a security certification of any listed project.
Map the complete connection
MCP's official architecture separates the host application, its clients and the servers that expose context. Local servers commonly use stdio, while remote services commonly use Streamable HTTP. The protocol standardizes the exchange; it does not decide your application's business permissions.
Write down the host, server publisher, actual endpoint, downstream service and account identity. For a repository assistant, the server might run on your machine while the data still comes from a remote code-hosting service. Calling the setup local does not mean every request or stored record remains local. Trace the actual path before choosing where secrets belong.
Review the tools you will actually expose
List the tools returned by the server and translate each into its possible effect. A repository integration might search code, read issues, create comments or change files. You may need only the first two. Record required arguments, affected accounts and whether repeating a call creates another object.
Our suggested first trial exposes only the tools needed for one bounded task. Use a disposable repository containing realistic sample issues and no production secrets. Ask the assistant to find an issue and draft a response outside the service. A successful search does not justify enabling every write tool in the same integration.
Keep a trial record you can repeat
Save the exact package or image version, selected tool names and permission settings. Capture sanitized request identifiers and outcomes, without copying access tokens into screenshots or issue reports. The following worksheet makes the intended behavior explicit before you start.
| Trial | Expected outcome |
|---|---|
| Read an allowed sample issue | Return its content and correct repository identity |
| Read outside the allowed repository | Deny access without exposing unrelated content |
| Revoke the credential | Stop accessing the protected service |
| Request an unavailable write tool | Explain the limitation without claiming success |
| Repeat a timed-out operation | Reveal whether the original operation completed |
Decide what earns continued access
After the trial, check the external service itself. The assistant's final sentence is not proof that a comment was saved, a file stayed unchanged or an access restriction held. Record the difference between unavailable functionality, authorization failure and an ambiguous result that needs investigation.
Our suggested release record names an owner, the approved use case, permitted tools, update procedure and revocation procedure. Revisit it when the server adds tools, changes operators or requests broader access. If the publisher, endpoint or permission scope remains unclear, retain the project in the shortlist without attaching production credentials. That leaves a useful path forward: ask for the missing evidence and repeat the specific failed check.
