pctx is an open-source framework designed for connecting AI agents to various tools and Model Context Protocol (MCP) servers, enabling seamless interactions and enhanced functionality. This program operates as a stateless HTTP server for Code Mode sessions or as a unified MCP server, allowing developers to aggregate multiple upstream MCP servers and manage connections efficiently. Key features include a Code Mode interface for efficient agent interaction, secure authentication, and a simple command-line interface for configuration and management.

The framework supports both Python and an upcoming Node SDK, making it versatile for developers working in different programming environments. With the capability to run agents in a sandboxed environment, pctx ensures secure execution of LLM-generated code while maintaining strict isolation from system resources. Additionally, it provides tools for connecting and managing multiple MCP servers, simplifying the process for developers looking to build sophisticated AI solutions.
