Mcpblox: CLI for transforming and composing MCP servers (github.com)

Mcpblox has been launched as a new command-line interface (CLI) tool that allows users to transform and compose Model Context Protocol (MCP) servers using natural language prompts. This programmable proxy enables developers to modify existing MCP servers by renaming tools, hiding unnecessary features, reformatting outputs, and creating synthetic tools—all without altering the original server setup. Users can easily execute transforms through commands like `npx mcpblox --upstream "your-mcp-server" --prompt "your transform"`, facilitating a flexible and dynamic way to modify server interactions. The significance of Mcpblox lies in its ability to harness the power of large language models (LLMs) to streamline and automate server adaptations. Through LLM-generated JavaScript transform functions executed in a safe, sandboxed environment, Mcpblox can orchestrate complex transformations with minimal overhead. This feature not only enhances the user experience but also allows for chaining multiple transformations through Unix pipes, paving the way for sophisticated, multi-stage processing of data. With caching mechanisms and transparent proxying capabilities, Mcpblox presents an innovative solution for the AI/ML community, promoting more intuitive and efficient workflows in server management and API interactions.
