Course Summary

Congratulations on completing "Building Custom MCP Tools with Python"!

Throughout this course, you’ve built a complete MCP server that connects Neo4j graph databases with AI tools using the Model Context Protocol.

Understanding MCP Fundamentals

You now know how to:

  • Create MCP servers using the FastMCP framework

  • Define tools that AI assistants can call

  • Expose resources through URI patterns

  • Create prompts for guided user interactions

Working with Neo4j

You’ve learned to:

  • Connect to Neo4j using lifespan management

  • Query graphs with the Neo4j Python driver

  • Handle database connections securely with environment variables

  • Access the driver through the Context object

  • Write efficient Cypher queries

Building Production-Ready Tools

You’ve mastered:

  • Implementing pagination for large datasets

  • Adding logging and progress reporting

  • Handling errors gracefully

  • Validating inputs and queries

  • Structuring responses consistently

Creating Deterministic Workflows

You can now:

  • Use MCP tools to explore graph schemas

  • Validate Cypher statements before implementation

  • Transform probabilistic AI suggestions into reliable code

  • Build tools that generate and test queries systematically

Pro Tips

Performance

  • Use lifespan management for connection pooling

  • Implement pagination for queries that return many results

  • Add proper indexes to support your query patterns

Security

  • Never hardcode credentials

  • Store sensitive configuration in environment variables

  • Validate all user inputs before querying

Best Practices

  • Test queries with MCP tools before implementing them

  • Add comprehensive logging for debugging

  • Use the Context object for progress reporting

  • Return structured data for easier consumption
