Agent Zero — ERC-8004 Trust Filter missed 2 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

agent

get_agent_summary

Objective, counts-only signals for one ERC-8004 agent. Args: chain: one of "base", "ethereum". agent_id: the numeric ERC-8004 agent id. Returns reachability, TLS validity, x402 support, payments-received (boolean only), MCP tool count, OpenAPI method count, well-known presence, owner-named (boolean), and a neutral status label (Live & monetized / Live, no payments / Stub or unreachable). No owner identity string and no payment amounts — those are paid. Returns an `error` field if the agent is not indexed. Use this to vet a counterparty agent before transacting. Paid counterpart: `GET /v1/intel/agent/{agent_id}?chain={chain}` (x402, USDC on base-mainnet) unlocks trust_verdict (safe_to_transact / caution / avoid / insufficient_data), readiness_score, Sybil-adjusted reputation, and the commerce-backed breakdown — the decision-driving values this free response returns as `null` inside a `locked` map. Every response carries an `unlock` block with the exact paid endpoint, price, and payment discovery.

coverage

get_coverage_stats

Live coverage of the ERC-8004 agent economy across Base and Ethereum. Returns counts only: how many agents are indexed, how many expose a live MCP server / OpenAPI / well-known card, total MCP tools and OpenAPI methods observed, contracts verified, EOAs and owners identified, plus a per-chain breakdown. No names, addresses, or handles. Use this to size the market and see where capability density is growing. Paid counterpart: `GET /v1/intel/market` (x402, USDC on base-mainnet) returns the full capability market map — which capabilities are saturated vs open, per-capability agent lists, and momentum. Every response from this free tool carries an `unlock` block with the exact paid endpoint, price, and payment discovery.

leaderboards

get_leaderboards

Top ERC-8004 agents by live capability, plus the most recently indexed. Three ranked lists — top by live MCP tool count, top by OpenAPI method count, and most-recently indexed — each with agent_id, chain, public name, a shareable detail URL, and the relevant count. Names and counts only: no owner wallets, handles, or endpoint URLs. Use this to find the most capable / most active agents to integrate or watch. Paid counterpart: `GET /v1/intel/trending` (x402, USDC on base-mainnet) returns trending intel — top earners, fastest-rising agents, and integration candidates ranked with the signals behind the ranking. Every response from this free tool carries an `unlock` block with the exact paid endpoint, price, and payment discovery.

network

get_network_teaser

A capped teaser of the on-chain agent-to-agent payment graph. Returns connected agents (nodes) and the value flowing between them (edges), capped to a small connected sample (≤200 nodes). This is a truncated preview, not the full network. Use it to see who pays whom in the agent economy. Paid counterpart: `GET /v1/intel/graph` (x402, USDC on base-mainnet) returns the full agent-to-agent payment graph — every node and edge with USDC/ETH amounts and no node cap. Every response from this free tool carries an `unlock` block with the exact paid endpoint, price, and payment discovery.

Agent Zero — ERC-8004 Trust Filter — questions

Answers built from our own checks of this server.

What can Agent Zero — ERC-8004 Trust Filter do?

It exposes 4 tools, read directly from the server on our last check. Among them: get_agent_summary, get_coverage_stats, get_leaderboards, get_network_teaser. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Agent Zero — ERC-8004 Trust Filter working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 671 ms. The bar chart above shows every period we have measured.

How do I connect Agent Zero — ERC-8004 Trust Filter?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Agent Zero — ERC-8004 Trust Filter need an API key?

No. Agent Zero — ERC-8004 Trust Filter completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Agent Zero — ERC-8004 Trust Filter?

It answers our handshake in 671 ms on average, which is faster than 18% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
