Check what a paid x402 endpoint or MCP server delivered, from probes anyone can repeat.

The xyz.teppi/teppi Model Context Protocol (MCP) server checks what a paid x402 endpoint or MCP server delivered, using probes anyone can repeat. Its purpose is to provide inspectable results from repeatable checks, focused on delivery verification rather than content transformation.

🛠️ Key Features

Verifies delivery from a paid x402 endpoint or another MCP server
Uses repeatable probes for inspection
Exposes 3 tools (toolCount: 3)

🚀 Use Cases

Confirm what an x402 endpoint or MCP server actually delivered
Repeat and compare probe results across runs

⚡ Developer Benefits

Repeatable probe approach supports independent verification
Clear scope centered on delivery checking for x402/MCP sources

⚠️ Limitations

Limited information available: only delivery checking, probe repeatability, and tool count are described

Captured live from the server via tools/list.

search_capabilities

Search paid agent capabilities by task description. Returns the price, the input and output schemas, the networks each one settles on, and what has been verified about it. Use before paying an x402 endpoint you have not used.
