Review MCP server transport configuration and identify stdio servers, remote endpoints, legacy SSE settings, transport mismatches and insecure HTTP.
Local MCP servers commonly use command-based stdio configuration while remote servers use HTTP-based endpoints. This checker classifies each server and flags ambiguous or insecure transport settings.
No remote URL is contacted during analysis.
Check MCP transport configuration for stdio, remote HTTP, legacy SSE, mixed command/URL fields and unencrypted remote endpoints.
Use MCP Transport Config Checker as a focused pre-flight utility while building, reviewing or debugging an MCP integration. Paste the relevant configuration, protocol message, metadata, schema or value into the tool and review the returned findings before the same data reaches a production client or server.
This validator is useful before configuration is committed, shared with another client or moved into production. Structural validation catches many integration problems early, but runtime behavior should still be tested with the exact client and server implementation you use.
A clean result means the input passed the rules implemented by this utility. It does not guarantee application security, protocol interoperability or correct business behavior. Test important integrations against the exact MCP client, SDK, gateway and server versions used in your deployment.
