Unlock the Power of AI Agents with FastAPI-MCP and UBOS

In the rapidly evolving landscape of AI, particularly with the rise of Large Language Models (LLMs) and AI Agents, the ability to seamlessly integrate these models with external data and tools is paramount. This is where the Model Context Protocol (MCP) comes into play. MCP standardizes how applications provide context to LLMs, enabling them to access and interact with real-world information and functionalities. FastAPI-MCP, a zero-configuration tool, bridges the gap between your FastAPI applications and the world of AI Agents, making it easier than ever to expose your endpoints as MCP-compatible tools.

What is FastAPI-MCP?

FastAPI-MCP is a powerful tool designed to automatically expose FastAPI endpoints as Model Context Protocol (MCP) tools. It eliminates the complexities of manual configuration, allowing developers to focus on building robust and feature-rich applications. With FastAPI-MCP, you can effortlessly integrate your existing FastAPI applications with AI Agents and LLMs, unlocking new possibilities for automation, data analysis, and intelligent decision-making.

Key Features of FastAPI-MCP

• Zero Configuration: The core philosophy of FastAPI-MCP is simplicity. It requires no manual configuration, automatically detecting and converting your FastAPI endpoints into MCP tools.
• Direct Integration: Seamlessly mount an MCP server directly to your FastAPI application, streamlining the integration process.
• Automatic Discovery: FastAPI-MCP automatically discovers all FastAPI endpoints and converts them to MCP tools, saving you valuable time and effort.
• Schema Preservation: It preserves the schemas of your request and response models, ensuring data integrity and consistency.
• Documentation Preservation: Your endpoint documentation, as defined in Swagger, is preserved, providing clear and comprehensive information for AI Agents interacting with your APIs.
• Flexible Deployment: Deploy your MCP server alongside your FastAPI app or separately, offering maximum flexibility and scalability.

Use Cases of FastAPI-MCP

FastAPI-MCP opens up a wide range of use cases for integrating AI Agents with your applications. Here are a few examples:

• AI-Powered Automation: Automate complex tasks by exposing your application’s functionalities as MCP tools. AI Agents can then orchestrate these tools to perform actions such as data retrieval, processing, and decision-making.
• Intelligent Data Analysis: Enable AI Agents to access and analyze data from your applications, providing valuable insights and predictions. For example, an AI Agent could analyze sales data to identify trends and recommend strategies for increasing revenue.
• Personalized User Experiences: Customize user experiences by allowing AI Agents to access user data and preferences. An AI Agent could then tailor content, recommendations, and interactions to individual users.
• Real-Time Decision Making: Empower AI Agents to make real-time decisions based on data from your applications. This is particularly useful in scenarios such as fraud detection, risk management, and autonomous systems.
• Enhance Existing AI Agents: Integrate your existing AI Agents with new functionalities by exposing them as MCP tools. This allows you to expand the capabilities of your AI Agents and create more sophisticated solutions.

Installation and Basic Usage

Installing FastAPI-MCP is straightforward. Using uv, a fast Python package installer:

bash uv add fastapi-mcp

Alternatively, you can use pip:

bash pip install fastapi-mcp

To use FastAPI-MCP, simply add an MCP server to your FastAPI application:

python from fastapi import FastAPI from fastapi_mcp import FastApiMCP

app = FastAPI()

mcp = FastApiMCP( app,

Optional parameters

name=“My API MCP”, description=“My API description”, base_url=“http://localhost:8000”, )

Mount the MCP server directly to your FastAPI app

mcp.mount()

Your auto-generated MCP server will then be available at https://app.base.url/mcp.

Advanced Usage and Customization

FastAPI-MCP offers a variety of advanced features for customization and control:

• Customizing Schema Description: Tailor the schema description to provide more detailed information to AI Agents.
• Customizing Exposed Endpoints: Control which FastAPI endpoints are exposed as MCP tools using Open API operation IDs or tags.
• Deploying Separately from Original FastAPI App: Deploy the MCP server separately from your FastAPI application for greater flexibility.
• Adding Endpoints After MCP Server Creation: Refresh the MCP server to include new endpoints added to your FastAPI application.

Integrating FastAPI-MCP with UBOS: The Full-Stack AI Agent Development Platform

While FastAPI-MCP simplifies the process of exposing your APIs as MCP tools, integrating them effectively into a comprehensive AI Agent ecosystem requires a robust platform. This is where UBOS comes in. UBOS is a full-stack AI Agent Development Platform designed to help businesses orchestrate AI Agents, connect them with enterprise data, build custom AI Agents with their own LLM models, and create sophisticated Multi-Agent Systems.
