## Quality 85/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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: 100 (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
- pass `tools.annotations`: 4 of 4 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 609 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 50 (weight 15)

- pass `stability.changes`: 4 tool changes in 30 days
- fail `stability.rug_pull`: 3 tools kept their name but changed most of their description in 30 days; review before trusting them

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

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

- tools: 4, about 609 tokens to load them all
- tool set hash: b92814484c338ceda807bcb8e49c9966
- tools last changed: 2026-10-13T04:46:00.536Z
- badge: [![protogrid quality](https://protogrid.dev/badge/us.pulsewatch.api/status.svg)](https://protogrid.dev/servers/us.pulsewatch.api/status)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-13 `vendor_status` changed (description, annotations) **meaning changed**
  - before: Is this vendor down? Current status, confidence, active incidents, 30-day uptime and freshness for one SaaS/cloud vendor, read live from PulseWatch. Unknown vendors return an error and are not charged.
  - after: Check whether one SaaS or cloud vendor (e.g. Stripe) is down right now: current status, confidence, active incidents, 30-day uptime and how fresh the data is, read live from PulseWatch. Use it for one vendor. Call list_vendors (free) first if you are not sure the vendor is tracked: unknown vendors return an error and are not charged. Read-only. Costs $0.01 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure is not charged.
- 2026-10-13 `pricing` changed (description, annotations) **meaning changed**
  - before: FREE. Prices, network and payment address for the paid tools.
  - after: Free. Return the price of every paid tool, the payment network (Base), the receiving address and the data source. No input, no network request, no payment.
- 2026-10-13 `validate_vendor` changed (description, inputSchema, annotations) **meaning changed**
  - before: FREE. Check a vendor name/domain format before paying. Format only; use list_vendors to confirm it is tracked.
  - after: Free. Check that a vendor name, slug or domain is well-formed and see how it will be matched. Format only and offline (no network request, no payment); use list_vendors to confirm the vendor is actually tracked.
- 2026-10-13 `list_vendors` changed (description, inputSchema, annotations)
  - before: FREE. List/search the vendors PulseWatch tracks (slug, name, category). Use before paying to confirm a vendor is tracked.
