What this MCP does

Searches and evaluates paid x402 agent capabilities, verifies endpoint behavior and pricing, and plans executable routes within a budget.

check_exposure
What your paid dependencies deliver
Look up every paid endpoint your agents call in one go, added up by the address each one pays: which are unknown to the record, which took money and returned nothing, which list what they do not serve, and how much monthly spend sits on each. Unknown is reported as unknown, never as bad.

check_grade
What has been verified
Return what has been verified about an x402 endpoint or its url: whether it answers, what it charges, and whether that price has moved. Answers unrated rather than guessing when the evidence is thin. Works for endpoints Teppi does not operate, and a url never seen is put in line for a free handshake, so ask again in an hour.

get_capability
One capability in full
Full detail for one capability: schemas, pricing, networks, the seller behind it, and every observation recorded against it.

plan_route
Plan a route
Turn a goal and a budget into an ordered list of paid endpoints that could reach it, with a cost estimate and what has been verified about each step. Moves no money and buys nothing: it returns the plan for you to run yourself.

search_capabilities
Search paid 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. Sort by verified to put the ones with the most evidence behind them first. Use before paying an x402 endpoint you have not used.
