What is gomcptest?

gomcptest is an experimental platform that allows developers to test and prototype agentic systems using the Model Context Protocol (MCP). It provides a custom-built host that mimics the OpenAI API while actually using Google's Gemini models through Vertex AI.

How to use gomcptest?

The system consists of a custom host server and various tools that can be combined to create specialized agents. You can build the tools, configure the environment, and then interact with them through the CLI or API interface.

Use Cases

Ideal for developing and testing specialized AI agents for code scanning, security analysis, automated documentation, data processing, and other developer productivity tools.

Key Features

OpenAI API Compatibility
Supports the OpenAI v1 chat completion format for easy integration with existing tools
Google Gemini Integration
Uses VertexAI API to interact with Google's Gemini models
Streaming Support
Provides real-time streaming responses for better user experience
Function Calling
Allows models to call external functions and incorporate results
MCP Tool Integration
Works with various MCP-compatible tools (Bash, File Editing, Grep, etc.)
Advantages
Flexible testing environment for agentic systems
OpenAI-compatible API makes integration easy
Supports multiple powerful tools out of the box
Streaming responses enable real-time interaction
Limitations
Proof-of-concept quality (not production-ready)
Requires Google Cloud Platform access
Potential security risks from tool execution
Limited documentation as an experimental project
