Common questions about connecting and running Preflight.
What does the preflight MCP server validate?
It checks whether your MCP server meets the requirements for publishing to the MCP Registry, Smithery, or npm. It validates server configuration, metadata, and compliance with registry standards before submission.
How do I connect to the preflight server?
The preflight server is hosted at https://skillfoundry.synaplex.ai/products/preflight/mcp/ and uses HTTP transport. Connect your MCP client to this endpoint to run validation checks on your server.
Can preflight validate servers for multiple registries?
Yes, preflight supports validation for the MCP Registry, Smithery, and npm. It checks compatibility with each registry's specific requirements in a single validation run.
What happens if my server fails preflight validation?
Preflight will report which requirements your server doesn't meet. You can then fix the identified issues before attempting to publish to any registry.
Is preflight required before publishing my MCP server?
While not strictly required, running preflight validation before publishing is a best practice to catch configuration and metadata issues early and avoid rejection from registries.
