Server tool list (10)

Raw names from tools/list. Only developers need these.

search_kitsSearch the Agentropolis index (MCP servers, x402/MPP paid HTTP APIs, A2A agents, kits). Read-only; never pays. Trust scores come only from verified non-wash payments. First-party kits (Featured from Seenly, an affiliated publisher) are returned in a separate labeled block.
get_kitFull listing detail by id (from search_kits).
get_kit_manifestMachine-readable kit manifest (invoke endpoints, pricing hints, discovery files, trust) for a listing.
call_kitForwards your request to the seller's x402 endpoint and returns the seller's response. If the seller answers 402, you get its payment requirements unchanged: sign the payment with YOUR OWN wallet to the seller's payTo, then call again with x_payment (x402 v1) or payment_signature (x402 v2). Agentropolis forwards the payment unchanged, never holds keys or funds, never settles, and charges no fees. Only listings with links.call / buy=relay_x402 are supported.
list_categoriesCategories with listing counts.
list_sourcesWhich directories were ingested or excluded, and why (terms/robots).
trust_methodHow hub trust scores are computed and their limits.
bazaar_linkReturns a link to search Coinbase's Bazaar directly. Agentropolis does not cache or republish Bazaar data.
market_snapshotWash-filtered x402 paid-usage by category (x402-list CC BY 4.0 data).
