https://getelva.ai/blog Engineering notes from the Elva team: API discovery, contracts and breaking-change policy, MCP servers in production, and what agents need from APIs. en Tue, 01 Sep 2026 00:00:00 GMT https://getelva.ai/blog/api-test-generation-tools-compared https://getelva.ai/blog/api-test-generation-tools-compared Spec-driven fuzzers, traffic-recording tools, AI request assistants, and security-focused generators all claim to "generate API tests." A researched map of what each actually generates, from what source, and what it misses.

A researched map of what actually produces a reference doc when you don't: collection imports, AI write-ups, traffic discovery, and code-derived catalogs.

Thu, 27 Aug 2026 00:00:00 GMT Elva Team OpenAPI Engineering https://getelva.ai/blog/mcp-vs-rest-api https://getelva.ai/blog/mcp-vs-rest-api MCP does not replace REST. It changes who the caller is. What that shift means for interface design, auth, error messages, and operations.
