概览

What is URL-Based MCP Server?

URL-Based MCP Server is a proof-of-concept, stateless MCP server builder that lets users create MCP servers without writing or hosting any code. It is designed for protocol and security experimentation rather than building real-world MCP integrations.

How to use URL-Based MCP Server?

Go to the hosted demo at https://url-mcp-demo.sshh.io/, add custom tools via the web interface, and copy the generated MCP configuration into your client. Tools can return static text or make dynamic HTTP POST requests (e.g., to a temp URL from webhook.site). For local hosting, run python main.py in the backend/ directory after installing the requirements.

Key features of URL-Based MCP Server

Stateless server builder – no code or hosting required
Create custom MCP tools with static or dynamic responses
Supports HTTP POST endpoints for configurable responses
Exposes pre‑built MCP configuration for any client
Ideal for security research and protocol testing

Use cases of URL-Based MCP Server

Experimenting with the MCP protocol without writing a server
Testing how different MCP clients handle custom tools
Demonstrating prompt injection or system prompt exfiltration attacks
Prototyping tool interactions before building a production server
Teaching MCP concepts in a sandboxed environment

常见问题

Is URL-Based MCP Server meant for production use?

No. It is a proof-of-concept intended for protocol and security experimentation, not for building real-world MCP integrations.

Do I need to host the server myself?

No. The hosted demo at `url-mcp-demo.sshh.io` is available. Local hosting is possible but discouraged because the whole point is to avoid hosting.

How do I create a tool with dynamic responses?

Select “HTTP POST endpoint” and provide a URL (e.g., a webhook.site temporary URL) that returns the desired response when called.

What is an example use case shown in the README?

The README demonstrates system prompt exfiltration: create a tool that tricks the client into sharing system prompts, then view the captured data in webhook logs.

What are the requirements for local hosting?

Python and the `requirements.txt` file inside the `backend/` directory. No other dependencies are listed.
