MCP Bridge by Appfactor vs YepCode

Import OpenAPI 3, GraphQL introspection, WSDL, or gRPC schemas and automatically turn every operation into a typed MCP tool with output schemas and annotations.

MCP Resources, hybrid semantic search, and Code Mode let agents find the right tool instead of loading every definition, so large APIs still fit in a working context window.

Guardrails, validation, and optional human approval run before a call, while response shaping and output guardrails scan what comes back.

Bearer, Basic, API key, OAuth2, and On-Behalf-Of identity let the backend authorize the real user behind each agent request, with fail-closed token exchange.
