onemcp
One MCP Portal To Rule Them All
onemcp is a Model Context Protocol (MCP) portal that unifies all of your MCP servers behind a single endpoint. Instead of connecting your AI client to dozens of individual servers, each with its own URL and credentials, your client connects to one portal URL and the portal handles the routing. It replaces hundreds of tool definitions with just three meta-tools, giving agents a ~97% smaller context footprint per request (~500 tokens instead of ~15,000).
Use Cases
- Teams running 20+ MCP servers (GitHub, Slack, Postgres, etc.) for AI agents in Claude, Cursor, and other clients
- Developers who want to cut context-token spend when agents make repeated tool calls
- Teams that need to shorten system prompts from thousands of tool schemas down to a few meta-tools
- Platform teams managing credentials across multiple environments and portals
- Agent builders who want to script against tools (search, describe, execute) rather than call hundreds of individual tool
- Teams that need to debug what their agents are actually calling via request logs
