## Editorial notes
Speakeasy is useful when an API team wants agent-facing and developer-facing surfaces to come from the same reviewed contract instead of hand-written glue. It can generate type-safe SDKs, CLIs, Terraform providers, contract tests, and standalone MCP servers from OpenAPI, making it a strong fit for teams exposing APIs to Claude-adjacent agents or internal developer platforms.
## Source notes
- The official documentation covers SDK generation from OpenAPI, including CLI installation, `speakeasy quickstart`, account authentication, uploading a local or remote API document, and choosing SDK or MCP generation.
- Speakeasy's standalone MCP documentation says MCP servers can be generated directly from OpenAPI or Swagger specifications, with API operations becoming discoverable tools and scoping controls for which operations are available to agents.
- The docs include deployment paths for generated MCP servers, including Cloudflare Workers and Gram, plus customization of tool names, descriptions, prompts, resources, and OAuth.
- The GitHub repository is `speakeasy-api/speakeasy` and describes Speakeasy as OpenAPI-native tooling for SDKs, Terraform providers, MCP servers, CLIs, and contract tests.

| Safety notes | ✓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. | ✓Generated clients, server stubs, docs, schemas, and config can expose every endpoint described in the source spec, including admin, billing, destructive, or internal operations. Regeneration can overwrite local generated files, remove hand edits, or produce broad diffs, so run in version control and review generated output before committing or publishing. Treat generated code like application code and review dependency changes, auth handling, retries, timeouts, pagination, validation, error behavior, and language-specific security defaults. OpenAPI descriptions, examples, operation names, and vendor extensions can become model context or generated comments, so do not use untrusted specs directly in agent workflows. | — missing | ✓Cognee ingests your data and builds a knowledge graph that agents read from, so treat graph content derived from external or user data as untrusted input and constrain what an agent may do based on it. Use tenant or user isolation so one tenant's knowledge is not retrieved for another, and review which sources are eligible for ingestion. The extraction and cognify steps call a model provider with ingested content; scope credentials to the minimum needed and keep them out of source control. Cognee runs self-hosted, so secure the graph and vector stores and their endpoints, and do not expose them on a public interface without protection. Keep production ingestion and permissions narrower than quickstart examples, and set retention rules for the accumulating graph. |
| Privacy notes | ✓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. | ✓OpenAPI specs can reveal endpoint paths, schemas, examples, server URLs, auth schemes, internal object models, and business workflow names. Normal CLI generation can run locally, but package managers, Docker pulls, CI jobs, hosted specs, and remote spec URLs may still create network and logging exposure. Generated documentation, clients, server stubs, CI artifacts, package releases, and screenshots can publish sensitive examples or internal routes if specs are not scrubbed first. Docker-based generation mounts local directories into the container, so review volume paths and output locations before running against private repositories. | — missing | ✓Ingested documents and the resulting knowledge graph can contain personal, confidential, or proprietary data; apply retention, deletion, and access-control policies to the graph and vector stores. Extraction, ontology generation, and embedding send ingested content to the configured model and embedding providers, which process it under their own terms; local models keep that on your machine. Because Cognee is self-hosted, ingested data stays in the stores you configure, but any external providers used for processing follow their own data-handling policies. Provider keys, ingested data, and graph exports should be treated as sensitive and kept out of version control. |
