Open-source code generation tool for producing API clients, server stubs, documentation, schemas, and configuration from OpenAPI specs.

Explore OpenAPI and Swagger specifications from Claude through a hosted MCP server that returns API overviews and per-operation schema details.

Community slash command runbook for OpenAPI contract review: lint base and head spec files with the documented Spectral CLI, compare rule failures, and classify release impact before merging API changes.

Agent Skill from mcp-use for turning OpenAPI or Swagger specs into MCP servers with operation-to-tool mapping, auth wiring, Zod schema generation, inspector testing, and streamable HTTP deployment.

HAPI MCP exposes OpenAPI specifications as MCP tools dynamically using the la-rebelion hapimcp project and MCP Registry package ai.com.mcp/hapi-mcp.

MCP-to-OpenAPI proxy server that wraps MCP servers and exposes their tools as standard HTTP endpoints with generated OpenAPI schemas and docs.

PostToolUse hook that compares a just-edited OpenAPI or JSON Schema document against the version committed in git and warns about backward-incompatible drift — removed OpenAPI paths and removed required properties — so breaking API changes are surfaced before they ship. Advisory only; it never blocks the edit.

Build and review Hono TypeScript APIs for Cloudflare Workers, Bun, Deno, Node.js, Vercel, Netlify, and other Web Standards runtimes with routing, middleware, validation, RPC clients, OpenAPI generation, deployment checks, and production safety review.

Build and maintain NestJS backend APIs with modules, controllers, providers, dependency injection, configuration, validation pipes, guards, interceptors, exception filters, OpenAPI docs, testing, and production safety review.

OpenAPI-native platform and CLI for generating type-safe SDKs, CLIs, Terraform providers, contract tests, and standalone MCP servers.

Expert Spectral review skill for auditing OpenAPI contracts, OAS rulesets, lint results, schema drift, CI gates, and API release readiness.

Self-hosted AI platform and web UI for Ollama, OpenAI-compatible APIs, RAG, Python function tools, model builder workflows, artifacts, web search, vector databases, enterprise auth, observability, plugins, and MCP-adjacent OpenAPI integrations.

Connect Claude to Twilio's hosted MCP server for read-only search and retrieval across public Twilio API specifications, Twilio Docs, SendGrid Docs, Segment Docs, and support articles.

Official Postman MCP Server for connecting Claude, Codex, Cursor, VS Code, Gemini CLI, and other MCP clients to Postman workspaces, collections, specifications, mocks, monitors, environments, API definitions, and code generation workflows.

Manage Docker and Kubernetes infrastructure from Claude — list environments, inspect containers, manage GitOps workflows, troubleshoot resources, and proxy Docker/K8s API calls — with the official Portainer MCP server generated from the Portainer OpenAPI spec.

Docker-deployed MCP gateway that aggregates downstream MCP servers into namespaces, endpoints, SSE, Streamable HTTP, OpenAPI, auth, and rate limits.
