What dependencies are required to run these tests?

The skill requires Bun, jq, and the navigator-server running on port 9334 to execute the automated test scripts.

Can I add my own custom test categories?

Yes, you can extend the suite by editing the run-mcp-tests.sh script to include new categories and specific JSON-RPC action calls.

What is the primary purpose of the MCP Testing skill?

It automates the validation of the Navigator MCP server's JSON-RPC interface to ensure correct browser automation behavior and protocol compliance.

How does this differ from standard CLI testing?

While CLI tests use shell arguments and HTTP, this skill tests JSON objects over stdio, which is the native communication method for Claude and other AI agents using MCP.

Security & Testing

Validates Model Context Protocol (MCP) server implementations for browser automation via automated JSON-RPC testing.

The mcp-testing skill provides a specialized framework for validating the Navigator MCP server, ensuring reliable browser automation through rigorous JSON-RPC protocol testing. It allows developers to automate schema validation, action routing, and error handling checks, providing a robust environment for regression testing and debugging AI agent tool integrations. By focusing on the specific differences between CLI and MCP protocols, this skill ensures that browser automation agents communicate correctly via standard I/O.
