pctx vs zapier-mcp

pctx: pctx sits between AI agents and MCP servers, aggregating multiple upstream MCP servers, handling authentication, and exposing tools through a unified Code Mode interface. It replaces sequential tool calling with code execution, resulting in significant token reduction. It supports multiple installation methods and provides Python SDK for agent development.; zapier-mcp: Zapier MCP is a remote MCP server that gives AI assistants direct access to 8,000+ apps and 40,000+ actions. It enables natural language commands to perform actions like sending Slack messages, updating Google Sheets, and more. The server is secure by default and supports multiple AI clients including Claude, ChatGPT, Cursor, and Windsurf.
