In the previous notebooks we have built a basic research agent and a Chief of Staff multi-agent framework. While the agents we have built are already powerful, they were still limited in what they could do: the web search agent is limited to searching the internet and our Chief of Staff agent was limited to interacting with its own filesystem.

This is a serious constraint: real-world agents often need to interact with other systems like databases, APIs, file systems, and other specialized services. MCP (Model Context Protocol) is an open-source standard for AI-tool integrations that allows for an easy connection between our agents and these external systems. In this notebook, we will explore how to connect MCP servers to our agent.

Need more details on MCP? For comprehensive setup instructions, configuration best practices, and troubleshooting tips, see the Claude Code MCP documentation.

Introduction to the MCP Server

1. The Git MCP server

Let’s first give our agent the ability to understand and work with Git repositories. By adding the Git MCP server to our agent, it gains access to 13 Git-specific tools that let it examine commit history, check file changes, create branches, and even make commits. This transforms our agent from a passive observer into an active participant in your development workflow. In this example, we’ll configure the agent to explore a repository’s history using only Git tools. This is pretty simple, but knowing this, it is not difficult to imagine agents that can automatically create pull requests, analyze code evolution patterns, or help manage complex Git workflows across multiple repositories.

# Get the git repository root (mcp_server_git requires a valid git repo path)
# os.getcwd() may return a subdirectory, so we find the actual repo root
git_executable = shutil.which("git")
if git_executable is None:
    raise RuntimeError("Git executable not found in PATH")

git_repo_root = subprocess.run(  # noqa: S603
    [git_executable, "rev-parse", "--show-toplevel"],
    capture_output=True,
    text=True,
    check=True,
).stdout.strip()

# Define our git MCP server (installed via uv sync from pyproject.toml)
git_mcp: dict[str, Any] = {
    "git": {
        "command": "uv",
        "args": ["run", "python", "-m", "mcp_server_git", "--repository", git_repo_root],
    }
}

Key Themes in Recent Development

Claude Agent SDK enhancements - Major work on agent implementations (research, chief of staff, observability agents)
New cookbooks - Tool search, crop tool, programmatic tool calling
CI/CD improvements - PR review workflows, issue templates, slash commands
Documentation - Added troubleshooting guides, codebase overviews

Working Directory Status

There are uncommitted changes in your working directory: - 22 modified files (mostly in claude_agent_sdk/) - 4 deleted files (documentation files in docs/) - 6 untracked files (new reports, plans, VS Code config)

These changes appear to be further work on the Claude Agent SDK agents, notebooks, and utilities that haven’t been staged or committed yet.

2. The GitHub MCP server

Now let’s level up from local Git operations to full GitHub platform integration. By switching to the official GitHub MCP server, our agent gains access to over 100 tools that interact with GitHub’s entire ecosystem – from managing issues and pull requests to monitoring CI/CD workflows and analyzing code security alerts. This server can work with both public and private repositories, giving your agent the ability to automate complex GitHub workflows that would typically require multiple manual steps.

Step 1: Set up your GitHub Token

You need a GitHub Personal Access Token. Get one here and put in the .env file as GITHUB_TOKEN="<token>" > Note: When getting your token, select “Fine-grained” token with the default options (i.e., public repos, no account permissions), that’ll be the easiest way to get this demo working.

Also, for this example you will have to have Docker running on your machine. Docker is required because the GitHub MCP server runs in a containerized environment for security and isolation.

Docker Quick Setup: - Install Docker Desktop from docker.com - Ensure Docker is running (you’ll see the Docker icon in your system tray) - Verify with docker --version in your terminal - Troubleshooting: If Docker won’t start, check that virtualization is enabled in your BIOS. For detailed setup instructions, see the Docker documentation

Step 2: Define the mcp server and start the agent loop!

# define our github mcp server
load_dotenv(override=True)
github_mcp: dict[str, Any] = {
    "github": {
        "command": "docker",

Observability Agent as Module

The observability_agent/agent.py module wraps the observability pattern into a reusable send_query function. It imports and uses the shared visualization utilities from utils.agent_visualizer internally: - reset_activity_context(): Called automatically at the start of each query - print_activity(): Provides real-time feedback during execution - display_agent_response(): Renders the final result (controlled by display_result parameter)

This means you can use the module with minimal code:

# Reload the module to pick up any changes (useful during development)
from observability_agent.agent import send_query

# The module handles activity display, context reset, and result visualization internally
result = await send_query(
    "Check the CI status for the last 2 runs in anthropics/claude-agent-sdk-python. Just do 3 tool calls, be efficient."
)

CI Status Summary for `anthropics/claude-agent-sdk-python`

Commit	Message	Date	Status
`2437035`	chore: bump bundled CLI version to 2.0.58	Dec 3, 2025 20:09 UTC	⚠️ No CI status available
`9809fb6`	chore: release v0.1.11 (#383)	Dec 3, 2025 19:42 UTC	⚠️ No CI status available

Note: The GitHub API response doesn't include explicit CI/check status data. This typically means:
1. CI hasn't been triggered on these commits (both are automated commits from GitHub Actions)
2. The checks aren't exposed via the commit API endpoint

Recommendation: To get detailed CI run information, you'd need to check:
- GitHub Actions tab directly: https://github.com/anthropics/claude-agent-sdk-python/actions
- Or query the Checks API specifically for workflow runs

Both commits are automated maintenance commits (CLI bump and release version update), so they may intentionally skip full CI runs.

Multi-turn conversations work seamlessly - just pass continue_conversation=True:

# Example 2: Multi-turn conversation for deeper monitoring
result1 = await send_query("What's the current CI status for facebook/react?")

Conclusion

We’ve demonstrated how the Claude Code SDK enables seamless integration with external systems through the Model Context Protocol (MCP). Starting with local Git operations through the Git MCP server, we progressively expanded to full GitHub platform integration with access to over 100 GitHub-specific tools. This transformed our agent from a local assistant into a powerful observability system capable of monitoring workflows, analyzing CI/CD failures, and providing actionable insights for production systems.

By connecting MCP servers to our agent, we created an autonomous observability system that monitors GitHub Actions workflows, distinguishes between real failures and security restrictions, and provides detailed analysis of test failures. The system demonstrates how agents can actively participate in your DevOps workflow, moving from passive monitoring to intelligent incident response.

This concludes, for now, our journey through the Claude Code SDK tutorial series. We’ve progressed from simple research agents to sophisticated multi-agent orchestration, and finally to external system integration through MCP. Together, these patterns provide the foundation for building production-ready agentic systems that can handle real-world complexity while maintaining governance, compliance, and observability.
