The post explores building a local AI agent that can call external tools using a custom Model Context Protocol (MCP) server with Ollama's on-device LLM hosting.
It covers how MCP standardizes tool integrations, defining and validating tools with Pydantic, configuring Ollama for function calling, and orchestrating end-to-end interactions.
Key benefits like enhanced privacy, improved performance, and greater extensibility are highlighted, along with common pitfalls to avoid.
MCP, an open standard introduced by Anthropic, allows LLMs to discover and invoke external tools through a uniform RPC-style interface, simplifying integration and enhancing security.
