Overview

What is MCPC?

MCPC is an SDK for building agentic MCP (Model Context Protocol) Servers by composing existing MCP tools. It is designed for developers who want to create portable, collaborative agents that work across any MCP client.

How to use MCPC?

Install the package via npm, pnpm, or Deno, or run directly with the CLI using npx. Use the mcpc() function to define dependencies, write an agent description, and create a server. You can also use the website at mcpc.tech to generate agents interactively or add the MCPC builder agent to your MCP client for AI-assisted setup.

Key features of MCPC

  • Portability and agent interoperability across all MCP clients
  • Simple composition and fine-tuning of existing tools
  • Built-in MCP logging and OpenTelemetry tracing
  • Skills support following the Agent Skills specification
  • Flexible execution modes for different scenarios

Use cases of MCPC

  • Create powerful agentic MCP tools by describing your vision and referencing community tools
  • Fine-tune existing tools by modifying descriptions, parameters, or wrapping results
  • Build multi-agent systems by defining each agent as an MCP tool
  • Create custom coding assistants (e.g., a Codex/Claude Code fork)
  • Organize domain knowledge using Agent Skills for on-demand loading
