A new guide demonstrates how to assemble a sophisticated AI assistant by linking mcp-agent components with Gemini. The piece shows the process of configuring the environment and establishing an MCP tool server that supports features like web lookup, data evaluation, code execution, and weather updates. It shows how to expose each tool via HTTP endpoints and utilize clear JSON schemas for reliable communication. By bridging these tools with an MCP client using Gemini, the author highlights how decision-making driven by context can coordinate with on-demand tool operations. A focus on asynchronous design, detailed tool schemas, and a smooth interface between the MCP layer and Gemini’s generative system helps the resulting assistant remain modular, scalable, and ready for real-world use. The example code includes type hints and API definitions to guide further development.
The walkthrough opens by describing a function that automates the installation of required packages, including mcp-agent, Gemini, and various support libraries. Once run, this setup step confirms that the development environment is fully equipped before continuing.
The next step brings in key modules—from the Gemini API and web scraping tools to libraries for visualization and numerical processing. The guide also loads mcp-agent protocol handlers and sets up logging to capture execution details as the agent runs.
Central to the system is an MCPToolServer class that defines and manages each utility available to the agent: a web search tool, a data analysis module, a code executor, and a weather simulator. Each async method handles its task—retrieving encyclopedia text, generating charts, running code snippets, or crafting synthetic weather data—and returns results in a consistent format that makes it simple to add new capabilities later.
An MCPAgent class then links Gemini’s language model to this server and tracks the conversation history. In its request handler, the agent prompts the model to choose a tool or reply directly, initiates the chosen tool asynchronously, and merges the tool’s output into the final response. Configuration includes loading the Gemini API key and setting model parameters.
To demonstrate its functionality, the author runs a script that creates the agent, processes sample queries, and prints Gemini-assisted responses with brief pauses between calls. After that, an interactive prompt lists available tools, accepts freeform instructions, and illustrates the full end-to-end coordination, concluding with a concise recap of the covered concepts.
By the end, developers can deploy an MCP-based assistant that dynamically selects external services and incorporates their output into coherent answers. The example prompts validate its skill in searching online, analyzing data, generating visuals, and simulating scenarios. This blend of structured protocol routines with Gemini’s flexible reasoning serves as a template for building interactive, tool-enhanced AI agents.
