MCP Protocol: Building Agent Tool Integrations Training Course

Anatomy of the Protocol

• Limitations of function calling alone in complex agent ecosystems
• Core MCP components: tools, resources, prompts, and their JSON schemas
• MCP session lifecycle: initialization, tool listing, invocation, response, and termination
• Comparison of MCP against OpenAPI and GraphQL for exposing capabilities to agents

Creating a Stdio MCP Server

• Initiating a TypeScript MCP server using the official SDK
• Defining tool schemas with Zod and generating runtime validation
• Writing tool handlers that interact with internal REST APIs or databases
• Managing errors, partial outputs, and long-duration tool execution

Creating an HTTP MCP Server

• Migrating from stdio to HTTP for remote deployment and load balancing
• Implementing authentication via bearer tokens and mTLS
• Handling graceful degradation during HTTP connection failures mid-session
• Deploying HTTP MCP servers behind Kong or nginx with rate limiting

Client Integration Strategies

• Registering MCP servers with Claude Code via configuration files
• Linking OpenClaude to multiple MCP endpoints concurrently
• Developing a custom Python agent client using the MCP Python SDK
• Managing dynamic changes in tool availability at runtime

Resource and Prompt Exposure

• Providing read-only resources to enrich agent context
• Designing parameterized prompt templates to steer agent reasoning
• Dynamically updating resources as underlying data shifts
• Distinguishing between mutable tools and immutable resources for security clarity

Internal Tool Registry and Discovery

• Constructing an organization-wide MCP registry with metadata and ownership labels
• Enabling auto-discovery through DNS-SD or well-known endpoint files
• Managing tool versions and retiring legacy endpoints without disrupting clients
• Cataloging tools with natural language descriptions to enhance agent searchability

Enterprise Security Perimeters

• Enforcing authorization checks within tool handlers based on agent identity
• Isolating high-risk tools from general agent access via network segmentation
• Sandboxing tool execution using seccomp and gVisor containers
• Logging all tool invocations for compliance and forensic review

Performance and Reliability Engineering

• Configuring timeout policies for tool categories: databases, compute, and external APIs
• Implementing circuit breakers when downstream services exhibit instability
• Caching tool results to minimize redundant, high-cost computations
• Deploying MCP servers as sidecars versus standalone microservices

Cross-Platform Interoperability

• Verifying MCP server compatibility with Claude Code and Continue.dev clients
• Addressing transport negotiation variances across different platforms
• Developing polyfill adapters for non-MCP agent frameworks
• Establishing an internal cross-platform tool marketplace

Internal Evolution of the MCP Ecosystem

• Gathering developer insights on tool utility and precision
• Conducting quarterly tool audits to remove outdated integrations
• Onboarding new teams using self-service MCP server templates
• Contributing enhancements upstream to the open-source MCP specification
