The decision
Choose remote MCP for a provider-hosted connection your client can authenticate to. Choose a local server when you need local execution or the supported integration ships as a process. Evaluate credentials and permissions in either case.
Side by side
| Dimension | Local stdio | Remote HTTP |
|---|---|---|
| Runs where | Client-launched process | Independent network service |
| You manage | Runtime and local package configuration | Client connection and account access |
| Credential path | Commonly process environment | Server-specific OAuth or key setup |
| Check first | Process permissions and outbound calls | Endpoint ownership, authorization and region |
The transport changes the operating model
With stdio, the MCP client launches a subprocess. Streamable HTTP uses a network endpoint. This changes who installs, updates and operates the server, but not the need to understand what its tools can do.
For a local package, check the runtime and how the client receives environment variables. For a remote service, check connectivity, region and authorization support. “Local” does not mean offline: a local server may call external APIs using your provider credentials.
Follow the publisher’s current recommendation
Logfire now documents a hosted remote server with regional endpoints and browser authorization. Panther documents a local server with stdio and a self-hosted HTTP option. These are implementation-specific choices, not competing universal defaults.
A vendor’s migration from a package to a hosted service can change installation and credential handling. Keep the previous implementation’s history, but update the recommended setup link to the current publisher documentation.
Compare trust boundaries explicitly
A local process runs with the permissions of its execution environment. A remote server receives the requests and data you send to it. Decide what data may leave the machine, which resources the tools can access and who owns the credentials.
For team use, document how each person connects and how access is removed. A shared remote connection may have workspace-level consequences; a copied local configuration may accidentally share credentials. Neither transport is automatically the safer choice.
Use the same bounded task for the trial
Connect using the publisher instructions, list tools and perform a read with an expected result. Restart the client, revoke access and test the recovery experience. If comparing performance, keep the workload and provider data identical and report retries as well as successful timing.
Choose the deployment model your team can support. A remote endpoint can simplify installation, while a local process can give you control over the runtime. Availability, cost and permissions depend on the implementation; verify them instead of inferring them from the transport.
Your next step
Use these checks in a bounded proof of integration.
- Check supported runtime or endpoint and region.
- Document the credential and data boundary.
- Test restart, revocation and recovery.
- Avoid equating local with offline or remote with OAuth.
