## Quality 76/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 64 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 3 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_leaderboards (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_payable_x402_endpoints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_agent_summary (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,753 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 3 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 1,753 tokens to load them all
- tool set hash: 19411a298207139e9876923f443f1ba6
- tools last changed: 2026-10-12T04:55:30.783Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.onchainagentintel/agent-zero-intel.svg)](https://protogrid.dev/servers/io.onchainagentintel/agent-zero-intel)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-12 `list_payable_x402_endpoints` added
  - Directory of ERC-8004 agents that answered a well-formed HTTP 402 x402 challenge during our last field probe. OBSERVATION ONLY — not a score, ranking, or endorsement. Args (ALL OPTIONAL — call with `{}` for the top 10 across both chains): chain: one of "base", "ethereum" (omit for both). Default: null. limit: 1..10 rows (free-tier cap). Default: 10. Returns per-row raw probe facts: agent_id, chain, endpoint_url, http_402_ok, network, asset, price_usd as the challenge advertised, payTo_present (boolean — the actual address is paid), sibling_agent_ids (other ERC-8004 ids served by the same gateway row — the 'shared operator' cue), probed_at. Plus `total_endpoints_valid_402` and `total_agents_valid_402` so a caller can see what fraction of the surface this free slice covers. Source: the 0946 field-test one-shot probe (unauthenticated, read-only, no payment signed). See the `field_test_url` field for the full writeup. Paid counterpart: the paid x402 /v1/intel/* endpoints return the same-origin enriched intel on any single agent in this list — owner identity, payment history, peers, trust verdict, Sybil-adjusted reputation. Every response from this free tool carries an `unlock` + `paid_upgrade` block with the exact paid endpoint, price, and payment discovery.
- 2026-10-10 `agent_trust_teaser` added
  - Credit-score-style TEASER for one ERC-8004 agent's trust profile. Args (BOTH OPTIONAL — call with `{}` to see Agent Zero itself): chain: one of "base", "ethereum". Default: "base". agent_id: the numeric ERC-8004 agent id. Default: 19353 (Agent Zero, the agent serving this MCP endpoint). Example: `{}` returns Agent Zero on base; `{"chain": "base", "agent_id": 19353}` is the explicit form. By construction returns ONLY: name, chain, agent_id, public readiness_bucket, and a 1-line verdict headline. Every decision-driving value — trust_verdict, readiness_score, risk_flags, money-flow details, counterparty list, full score breakdown — is redacted as `null` and enumerated in the `locked` map. The response carries the exact paid endpoint URL (/v1/intel/agent/{agent_id}?chain={chain}), the x402 price as currently configured, and a one-line how-to-pay-via-x402 hint. Returns `error` with the same unlock pointer if the agent is not indexed, so a caller probing an unknown id still sees how to pay for a known one. Paid counterpart: `GET /v1/intel/agent/{agent_id}?chain={chain}` (x402, USDC on base-mainnet) returns the full trust verdict (safe_to_transact / caution / avoid / insufficient_data), readiness_score + sub-scores, Sybil-adjusted reputation, and the commerce-backed money-flow breakdown. Every response from this free tool carries an `unlock` + `paid_upgrade` block with the exact paid endpoint, price, and payment discovery.
- 2026-10-05 `get_agent_summary` changed (description, inputSchema)
  - before: 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.
  - after: Objective, counts-only signals for one ERC-8004 agent. Args (BOTH OPTIONAL — call with `{}` to see Agent Zero itself): chain: one of "base", "ethereum". Default: "base". agent_id: the numeric ERC-8004 agent id. Default: 19353 (Agent Zero, the agent serving this MCP endpoint). Example: `{}` returns Agent Zero on base; `{"chain": "base", "agent_id": 19353}` is the explicit form. 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.

- `agent_trust_teaser`: Credit-score-style TEASER for one ERC-8004 agent's trust profile.

Args (BOTH OPTIONAL — call with `{}` to see Agent Zero itself):
    chain: one of "base", "ethereum". Default: "base".
    agent_id: the numeric ERC-8004 agent id. Default: 19353 (Agent Zero, the agent serving this MCP endpoint).
Example: `{}` returns Agent Zero on base; `{"chain": "base", "agent_id": 19353}` is the explicit form.

By construction returns ONLY: name, chain, agent_id, public readiness_bucket, and a 1-line verdict headline.

    chain: one of "base", "ethereum". Default: "base".
    agent_id: the numeric ERC-8004 agent id. Default: 19353 (Agent Zero, the agent serving this MCP endpoint).
Example: `{}` returns Agent Zero on base; `{"chain": "base", "agent_id": 19353}` is the explicit form.

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.

Every response carries an `unlock` block with the exact paid endpoint, price, and payment discovery.
- `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.
- `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.
- `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.
