About Ollama Pydantic Project
Ollama Pydantic Project is a sample chatbot for developers exploring local Ollama models and Pydantic agents, with a Streamlit interface and MCP tool access.
Key features
- 01Local Ollama model responses
- 02Pydantic agent data validation
- 03Streamlit chat interface
- 04MCP server tool access
Use cases
- 01Testing a chat agent with a local model
- 02Interacting with an agent through a web UI
MCP support
The agent connects to an MCP server and uses the tools it provides.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

From the project READMEOllama Pydantic Project
Welcome to the Ollama Pydantic Project! This project demonstrates how to use a local Ollama model with the Pydantic agent framework to create an intelligent agent. The agent is connected to an MCP server to utilize tools and provides a user-friendly interface using Streamlit.
This project is part of the blog post: Building a TypeScript MCP Server: A Guide for Integrating Existing Services. Visit the blog to learn more about the concepts and implementation details behind this project.
Overview
The main goal of this project is to showcase:
- Local Ollama Model Integration: Using a locally hosted Ollama model for generating responses.
- Pydantic Agent Framework: Creating an agent with Pydantic for data validation and interaction.
- MCP Server Connection: Enabling the agent to use tools via an MCP server.
- Streamlit UI: Providing a web-based chatbot interface for user interaction.
Prerequisites
Before setting up the project, ensure the following:
- Python: Install Python 3.8 or higher. You can download it from python.org.
- Ollama Model: Install and run the Ollama server locally:
- Download the Ollama CLI from Ollama's official website.
- Install the CLI by following the instructions provided on their website.
- Start the Ollama server:
ollama serve - Ensure the server is running on
http://localhost:11434/v1.
- MCP Server: Set up an MCP server to enable agent tools. For more details, refer to MCP Server Sample.
Setup Instructions
Follow these steps to set up the project:
-
Clone the Repository:
git clone <repository-url> cd ollama-pydantic-project -
Create a Virtual Environment:
python3 -m venv venv -
Activate the Virtual Environment:
- On macOS/Linux:
source venv/bin/activate - On Windows:
venv\Scripts\activate
- On macOS/Linux:
-
Install Dependencies:
pip install -r requirements.txt -
Ensure the Ollama Server is Running: Start the Ollama server as described in the prerequisites.
-
Run the Application: Start the Streamlit application:
streamlit run src/streamlit_app.py
Usage
Once the application is running, open the provided URL in your browser (usually http://localhost:8501). You can interact with the chatbot by typing your queries in the input box. The agent will process your queries using the Ollama model and tools provided by the MCP server.
Example Interaction
Below is an example of how the chatbot interface looks when interacting with the agent:

Troubleshooting
- If you encounter issues with the Ollama server, ensure it is running on
http://localhost:11434/v1. - If dependencies fail to install, ensure you are using Python 3.8 or higher and that your virtual environment is activated.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
