What is One Mcp?
One MCP is a unified Model Context Protocol (MCP) server that aggregates multiple MCP servers into a single, unified interface. Instead of configuring separate MCP servers for different AI assistants like Claude Desktop, Cursor, Cherry Studio, Roo Code, and others, One MCP provides one centralized server that all your AI tools can connect to. This simplifies management, reduces system resource usage by eliminating redundant server instances, and offers a standardized way for AI models to interact with external tools and resources.
Key features include aggregating multiple MCP servers into one unified interface, supporting filtering of servers by tags for granular control, dynamic configuration reloading without server restart, graceful shutdown and resource cleanup, and a web-based management interface. It acts as a centralized reverse-proxy platform for MCP servers, accessible via a single HTTP server. The tool supports both stdio and HTTP transport types, with configurable port and host settings via environment variables.
One MCP is designed for developers and AI power users who work with multiple AI assistants and need to manage multiple MCP servers. It's particularly useful for those who want to simplify MCP server configuration across different AI assistants, control server access based on capabilities using tags, and reduce resource consumption by consolidating server instances. The tool works seamlessly with Claude Desktop, Cursor, and other AI coding tools.
The platform includes access to all MCP servers, a basic chat interface, and supports both standard AI models for free users and premium models for Pro subscribers. Free users get 5 messages per day with standard models like Gemini 2.5 Flash and GPT-OSS-120B, while Pro users get 10,000 AI credits monthly with premium models including Claude Opus 4.5, Gemini 3 Pro, and GPT-4o.

Frequently asked questions about One Mcp
What is One MCP?
One MCP is a unified Model Context Protocol (MCP) server that aggregates multiple MCP servers into a single, unified interface. It simplifies interaction with AI assistants by providing one centralized point of access instead of configuring separate servers for different clients like Claude Desktop, Cursor, and others.
What happens if I run out of credits?
If you exhaust your Pro credits, you can buy more credits at any time. There is no restriction on when or how much you can purchase.
What's the difference between using one vs. multiple MCPs?
With the Free plan, you can connect to one MCP server at a time. Pro users can connect to multiple MCPs simultaneously, enabling more powerful workflows and cross-tool integrations.
Do credits roll over?
Yes, unused credits roll over to the next month. You don't lose your remaining credits at the end of your billing cycle.
What AI models are available on the Free plan?
The Free plan includes standard AI models: Gemini 2.5 Flash and GPT-OSS-120B. These are suitable for getting started with MCPs and exploring AI capabilities.
What AI models are available on the Pro plan?
The Pro plan includes premium AI models: Claude Opus 4.5, Gemini 3 Pro, and GPT-4o. Pro users also get priority model access and flexible model selection.
How do I install One MCP?
You can run the server directly using npx: 'npx -y @1mcp/agent' for basic usage with SSE transport, or 'npx -y @1mcp/agent --config ~/Library/Application Support/Claude/claude_desktop_config.json' to use existing Claude Desktop config.
What transport types does One MCP support?
One MCP supports both stdio and HTTP transport types. The default is HTTP. You can configure this using the ONE_MCP_TRANSPORT environment variable.
Can I filter MCP servers by tags?
Yes, One MCP supports filtering servers by tags for granular control. You can control MCP server access based on capabilities using the ONE_MCP_TAGS environment variable with a comma-separated list of tags.
What AI assistants is One MCP compatible with?
One MCP is designed to work with various AI assistants including Claude Desktop, Cursor, Cherry Studio, Roo Code, and Claude. It provides a single unified server that all these assistants can connect to.
