## Quality 91/100 (new)

### 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 carries no ttlMs, so clients re-fetch it

### 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: 94 (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
- warn `tools.directory_hints`: 2 of 4 tools declare all four hints; missing: check_domain (destructiveHint); check_domains (destructiveHint)
- pass `tools.token_cost`: about 985 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: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`, `stability.new_links`: tool history recorded for 4 of the 7 days needed

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

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

- tools: 4, about 985 tokens to load them all
- tool set hash: dee3709c88026566a8c4a9d959a8a16a
- badge: [![protogrid quality](https://protogrid.dev/badge/io.agentsallowed/lookup.svg)](https://protogrid.dev/servers/io.agentsallowed/lookup)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `check_domain`: Before acting on a website for a user, check whether it lets AI agents browse, shop, book or log in, and whether there's an official agent route (UCP, ACP, MCP, Visa TAP, A2A, partner apps). Returns status (open|partial|announced|none, or unknown if we have no verified record), recommended_action (a suggestion based on public sources, not permission; the website's own terms always take priority), per-action allowances, routes, dated sources. Read-only.
- `check_domains`: Batch version of check_domain for up to 50 domains or URLs. Results are returned in input order. Read-only.
- `report_block`: Deprecated alias kept for older clients. Same as submit_update with type report_block (or report_works when result is works / official_route_found). Goes to human review; nothing auto-publishes.
- `submit_update`: Suggest a change to the database: add a brand (add_brand), correct a listing (correct_listing), report that an agent was stopped on a site (report_block), or report that a task now works (report_works). Every submission goes to a human review queue; nothing is published automatically, and a listing only changes once it is verified from a brand statement or official docs, reputable reporting, or our own documented test. Do not include personal data about the user.
