SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill provides automated MCP protocol conformance testing and Pydantic schema validation for MCP servers, reducing integration risk and speeding up test cycles.

Core Features & Use Cases

  • JSON-RPC 2.0 validation: Validate requests and responses against the JSON-RPC 2.0 spec using Pydantic models.
  • Tool schema and integration tests: Validate tool schemas, run async tests, and simulate MCP server interactions.
  • End-to-end integration scenarios: Execute full request/response cycles and error handling to ensure robust MCP server behavior.

Quick Start

Run the MCP protocol compliance tests against your MCP server to verify conformance and schema validation.

FAQPage Schema
How do I validate MCP server responses against the JSON-RPC 2.0 spec?▼

Validate MCP server responses against the JSON-RPC 2.0 spec by running automated conformance tests that use Pydantic models to verify request and response structures, ensuring strict protocol compliance.

What is the best way to automate async tool testing for an MCP server in CI?▼

Automate async tool testing for an MCP server in CI by executing async tool patterns and full request/response cycles that simulate server interactions and validate tool schemas.

Can I use Pydantic schema validation to check MCP tool definitions?▼

Yes, you can use Pydantic schema validation to check MCP tool definitions by applying automated conformance testing that validates tool schemas and simulates interactions to ensure robust server behavior.

Does MCP protocol compliance testing handle structured error handling?▼

MCP protocol compliance testing handles structured error handling by executing end-to-end integration scenarios that validate full request/response cycles and error handling to ensure robust MCP server behavior.

Why do I need Pydantic models for MCP protocol conformance testing?▼

You need Pydantic models for MCP protocol conformance testing because they provide strict JSON-RPC 2.0 validation and tool schema validation, reducing integration risk and speeding up test cycles.
