Model Context Protocol Tutorial

A new Composio guide shows developers how to connect Claude Code to Google Ads through the Model Context Protocol, or MCP, with working Python and TypeScript setups. (composio.dev) MCP is an open protocol for linking language models to outside tools and data, and Anthropic’s documentation describes it as the standard behind Claude connectors. The published MCP specification says it is meant to give model applications one common way to reach external systems. (claude.com) (modelcontextprotocol.io) Composio’s tutorial says the Google Ads connection can be made two ways: through Composio Connect, which it calls the direct option, or through the Composio software development kit for programmatic control. The page also says the same toolkit pattern is available across other agent frameworks, including the Claude Agent Software Development Kit and OpenAI Agents Software Development Kit. (composio.dev) The plumbing matters because Google Ads access is usually not a one-key setup. Google’s documentation says developers need OAuth 2.0 credentials and a separate developer token to make Google Ads Application Programming Interface calls. (developers.google.com 1) (developers.google.com 2) That makes MCP tutorials useful as a map for turning a chat model into a tool-using client. Anthropic said in a November 2025 engineering post that code execution with MCP can cut context overhead by as much as 98.7% when agents handle many tools. (anthropic.com) Composio frames its Google Ads guide around avoiding “OAuth hassles,” application programming interface breakage, and reliability problems while giving Claude Code one MCP endpoint for multiple apps. The tutorial page says developers can then manage Google Ads directly from Claude Code instead of moving data by hand between systems. (composio.dev) The guide lands as MCP is still changing. The specification site labels the March 26, 2025 version as an older release and points readers to a newer “latest” version, while the public GitHub repository shows active maintainer updates as recently as April 2026. (modelcontextprotocol.io) (github.com) For developers, the immediate takeaway is concrete: a model can draft code, call tools, and reach ad platform data through one protocol layer instead of a custom integration for each service. Composio’s page packages that pattern into copyable examples for two languages and a live Google Ads use case. (composio.dev)
