## Quality 80/100 (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: 75 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- 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: cartographer_status (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); find_x402_endpoints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); lp_real_yield_pool (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,155 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### stability: 100 (weight 15)

- pass `stability.changes`: 5 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name
- pass `stability.new_links`: no tool change named a new site

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

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

- tools: 7, about 1,155 tokens to load them all
- tool set hash: f68df24d4323e736418097b7c1708e2d

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-11-03 `x402_seller_check` added
  - Demand check for one Base x402 seller by payTo address, endpoint URL or host: on-chain USDC payers over up to 30 days, how many remain after removing small-funded wallets and market scanners, repeat buyers, USDC received, and how much depends on one wallet. Not charged for unknown or unmeasured sellers.
- 2026-11-03 `lp_real_yield_pool` added
  - Real-yield card for one Base concentrated-liquidity pool address: headline fee APR, LVR, net yield at a reference range, fee-to-LVR ratio with a confidence interval, and volatility. Not charged for unknown pools.
- 2026-11-03 `lp_real_yield_pools` added
  - Real yield of Base Uniswap v3, Aerodrome and Aero concentrated-liquidity pools: fee APR against LVR (loss-versus-rebalancing), with staking rewards and rebalancing costs, measured from on-chain swaps. Shows where a headline APR is lost to arbitrage. Not charged when nothing matches.
- 2026-11-03 `x402_endpoint_card` changed (description)
  - before: Trust card for one x402 endpoint URL: 7-day uptime from our probes, latency, last success, price, and the seller's on-chain USDC payers over 30 days. Not charged for unknown URLs.
  - after: Trust card for one x402 endpoint URL: 7-day uptime from our probes, latency, last success, price, and the seller's on-chain USDC payers over 30 days, with farmed wallets removed. Not charged for unknown URLs.
- 2026-11-03 `find_x402_endpoints` changed (description)
  - before: Ranks live x402 endpoints for a task such as 'web search', 'token price' or 'pdf to text'. Returns up to 10 endpoints ranked by text match, 7-day liveness probes and on-chain USDC payer counts. Not charged when nothing matches.
  - after: Ranks live x402 endpoints for a task such as 'web search', 'token price' or 'pdf to text'. Returns up to 10 endpoints ranked by text match, 7-day liveness probes and on-chain USDC payers with farmed wallets removed. Not charged when nothing matches.
