The Agent Skills Directory

[SAFE]: The skill serves as an educational and functional resource for developers implementing the Model Context Protocol (MCP). It contains guidance on project structure, tool design, and evaluation strategies.
[EXTERNAL_DOWNLOADS]: The documentation references official resources from the Model Context Protocol organization on GitHub (e.g., modelcontextprotocol/typescript-sdk, modelcontextprotocol/python-sdk). These are authoritative sources for the protocol and are used to provide the user with the most up-to-date SDK information.
[COMMAND_EXECUTION]: The provided Python script scripts/evaluation.py uses the mcp library to launch local MCP servers via the standard input/output (stdio) transport. This is a standard and intended mechanism of the protocol, used here specifically to allow developers to test their own server implementations during development.
[INDIRECT_PROMPT_INJECTION]: The evaluation harness is designed to interact with MCP servers and process their tool outputs. While this creates a theoretical surface for indirect injection if a server returns malicious content, the tool is intended for use in a local development context where the developer controls the server being tested.
