"openapi" matching MCP servers:

Enables passive reconstruction of an application's HTTP endpoints, WebSocket/event surfaces, payload schemas, and process architecture purely by observing labeled traffic, logs, and process metadata — never by sending requests to the target. Findings carry evidence levels and confidence, and can be exported as OpenAPI, AsyncAPI, JSON Schema, protocol catalogs, architecture maps, and candidate MCP capability surfaces.

Enables autonomous agents to turn high-level features into structured PRDs, user stories, Gherkin acceptance criteria, edge cases, and OpenAPI-compatible API contract skeletons. It exposes MCP tools for synthesizing requirements and generating endpoint specifications.

Enables generating documentation from source code and templates, building API references from OpenAPI specs, creating architecture diagrams, and searching, versioning, and exporting documents. Supports multiple output formats including Markdown, HTML, PDF, and DOCX.
