Server instructions

Agentropolis is a read-only search index for agent tools (MCP servers, x402/MPP paid APIs, A2A agents, kits). Typical flow: search_kits to find candidates, get_kit to compare trust and price, get_kit_manifest to learn how to call one, then call the seller directly (or use call_kit for listings marked buy=relay_x402). No auth. Agentropolis never initiates payments; the seller's live 402 challenge is authoritative for price.

Known tools 10

search_kits

Search the Agentropolis index of 41,803 agent-usable listings (MCP servers, x402/MPP pay-per-call HTTP APIs, A2A agents and kits) by task keywords, with optional filters.

Potential side effects

get_kit

Get the full Agentropolis record for one listing by id: summary, pricing, payment-verified trust evidence (verified buyers, settlements, wash flags, disclosed test sales), badge tiers, sources and links.

Potential side effects

get_kit_manifest

Get the kit.json v0.1 manifest for one listing: how to call it (HTTP, MCP or A2A endpoints), input/output schema references, payment offers (rail, network, asset, payTo, amount), discovery files and a trust summary.

Potential side effects

call_kit

Send a request to a listing's x402 endpoint through Agentropolis and get the seller's raw response back (status, headers, body).

Potential side effects

list_categories

List every category in the Agentropolis index with its listing count, largest first (about 18 snake_case ids such as web_search, crypto_onchain_data, llm_inference).

Inferred read-only

list_sources

List the registries and directories Agentropolis ingests or deliberately excludes, with each source's license or terms decision, robots handling and listing count (e.g.

Inferred read-only

get_trust_method

Explain how Agentropolis computes trust scores (method hub-trust-v0.1) and ranks search results: which payment evidence counts, wash-trading exclusions, low-sample caps, why our own test purchases never count, and what a null score means.

Potential side effects

get_bazaar_link

Build a URL that searches Coinbase's x402 Bazaar (Agentic.Market) for a query.

Inferred read-only

get_market_snapshot

Get 30-day x402 paid-usage statistics per category, with wash trading filtered out: services with paid usage, verified buyers, settlements, median listed price and listings excluded for wash signals.

Inferred read-only

get_roadmap

List Agentropolis platform features with status (live, partial, stub, planned), endpoint and guardrails: badges, the x402 relay, seller claims and analytics, sponsored placement, market data, billing.

Inferred read-only
