| Safety notes | ✓Starts a local inspector UI and proxy process for interactive MCP debugging. Only connect it to MCP servers and endpoints you trust during testing. | — missing | ✓Generated SDKs, CLIs, Terraform providers, and MCP servers can expose every operation described by an API contract unless the source spec and generation config are scoped deliberately. Standalone MCP servers generated from an OpenAPI document can turn API operations into agent-callable tools, so write, delete, billing, admin, and production operations need review, auth, and environment separation. Treat generated code like source code and review diffs, dependency changes, auth handling, retries, timeouts, pagination, and error behavior before publishing or wiring into agents. |
| Privacy notes | ✓Requests and tool responses from the inspected server may be visible in the local inspector session. Avoid testing with production credentials or private user data unless the environment is isolated. | — missing | ✓Hosted Speakeasy workflows may receive API contracts, endpoint paths, schemas, examples, auth scheme metadata, server URLs, and generated artifact configuration. Internal or pre-release OpenAPI documents can reveal private routes, customer-facing object models, operational controls, and service topology. Generated MCP servers, SDK telemetry hooks, CI logs, contract test output, and published documentation can expose request or response examples if specs are not scrubbed first. |
