**An agent can connect on its own if it already holds `INDEX_TOKEN`.** Remote endpoint behind a static API key or header. The registry never sees the value; the agent fills the placeholder.

## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 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: 71 (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: get_service_prices (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); compare_services (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_index_metadata (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 386 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`: no 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 386 tokens to load them all
- tool set hash: 476fd15ca1945eac3c5371b544b20533
- badge: [![protogrid quality](https://protogrid.dev/badge/app.rowb.prices/index.svg)](https://protogrid.dev/servers/app.rowb.prices/index)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `compare_services`: Compare two services on the cheapest published monthly price. Refuses to compare when one of them publishes no monthly subscription (returns comparable:false with the reason).
- `get_cheapest_by_category`: Return the cheapest published monthly price per category, with the source URL of each price.
- `get_index_metadata`: Report when this index was last read from the vendor pages, how many services it covers, and what it explicitly does not claim.
- `get_service_prices`: Get the published plans and the derived USD-per-unit cost for one service, with the source URL and the date it was read.
- `health_check`: Report whether this service is up and which version answered.
- `list_indexed_services`: List every OG-image, screenshot and template service in the index with its published prices and the page each price was read from. No AI, no estimation - only values copied from vendor pages.
