AI Agent for MCP Server OpenAPI
Integrate scalable OpenAPI endpoint discovery and request execution into your workflows. MCP Server empowers you to connect, search, and interact with any OpenAPI-compatible API using semantic search and direct request tools. Streamline integration, accelerate development, and unlock instant, context-aware API access for platforms like Claude Desktop and beyond.
Semantic OpenAPI Endpoint Discovery
Effortlessly locate relevant API endpoints using natural language queries. MCP Server leverages optimized semantic search and in-memory vector indexing (FAISS) to instantly surface endpoint details—enabling developers and AI agents to find the right API operation within milliseconds, even in massive OpenAPI specs.
- Instant Semantic Search.
- Find OpenAPI endpoints in real-time using powerful MiniLM-L3-based vector search, eliminating manual spec browsing.
- In-Memory Performance.
- Enjoy sub-second query responses with FAISS-powered in-memory indexing, even for large OpenAPI specifications.
- Endpoint-Centric Context.
- Get full parameter and response details for each API endpoint, ensuring context is never lost in search results.
- Remote Spec Support.
- Works with any remote OpenAPI JSON file—no local files or manual updates needed.
Direct API Request Execution
Move seamlessly from endpoint discovery to execution. MCP Server exposes tools for building and sending requests to any OpenAPI endpoint—supporting all HTTP verbs, authorization, custom headers, parameters, and bodies. Perfect for automating API workflows and powering AI-driven integrations.
- Make Any API Request.
- Send GET, POST, PUT, DELETE, or PATCH requests directly to any OpenAPI endpoint with full parameterization.
- Authorization & Headers.
- Easily add authentication tokens and custom headers for secure, real-world API integrations.
- Flexible Execution.
- Handle complex APIs, dynamic base URLs, and all parameter types with one unified toolset.
Flexible Multi-Instance & Deployment
Deploy multiple MCP Server instances for different API sets, use custom tool prefixes, and run at scale with Docker or Python. Configuration is simple—just set environment variables. Perfect for enterprise, finance, healthcare, or any team managing multiple OpenAPI sources.
- Multi-Instance Ready.
- Spin up separate MCP Server instances for different OpenAPI specs and business domains with isolated configuration.
- Docker & Python Support.
- Deploy using official multi-architecture Docker images or as a lightweight Python package.

What is MCP Server (mcp-server-any-openapi)
MCP Server (mcp-server-any-openapi) is an advanced tool developed by Bary Huang that enables AI agents, like Claude, to discover and call any API endpoint through natural language semantic search. It is specifically designed to handle large and complex OpenAPI specifications by efficiently chunking the documentation and using in-memory semantic search (powered by FAISS and MiniLM-L3) for fast, relevant endpoint discovery. The server allows integration of private and public APIs with AI systems, providing a scalable solution for enabling AI-driven automation, data analysis, and workflow execution. Optimized for speed and reliability, it’s particularly suited for scenarios where OpenAPI documentation is too large for traditional AI toolchains, making seamless API interaction possible for modern AI agents.
Capabilities
What we can do with MCP Server (mcp-server-any-openapi)
With MCP Server, users and AI agents can seamlessly integrate with any API—public or private—by leveraging semantic search for endpoint discovery, even from large OpenAPI docs. The platform supports end-to-end API invocation from search to request execution, making it ideal for automating complex workflows, powering AI assistants, and rapidly prototyping integrations.
- Discover API Endpoints
- Instantly find relevant API endpoints using natural language queries.
- Handle Large API Docs
- Efficiently chunk and search massive OpenAPI specifications without loss of endpoint context.
- Execute API Requests
- Make real-time API requests directly from the server after endpoint discovery.
- Integrate Private APIs
- Easily connect AI agents to internal or private APIs for secure and scalable automation.
- Accelerate AI Workflows
- Enable advanced AI-driven automation, data extraction, and workflow management with minimal setup.
What is MCP Server (mcp-server-any-openapi)
AI agents can benefit tremendously from MCP Server by gaining instant access to any API, regardless of specification size. The platform’s semantic search and fast request execution allow agents to understand, choose, and interact with the right API endpoints using natural language—enabling true API autonomy. This dramatically widens the range of tasks agents can perform, from automating business processes to integrating novel data sources and services in real time.
