## Quality 100/100 (new)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### 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`: 3 of 3 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 502 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

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

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 5 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: 3, about 502 tokens to load them all
- tool set hash: 9ec65e86c35444e8187468cb835145a9
- badge: [![protogrid quality](https://protogrid.dev/badge/dev.workers.mike-tusa.burnercheck/burnercheck.svg)](https://protogrid.dev/servers/dev.workers.mike-tusa.burnercheck/burnercheck)

## Tools (3)

- `check_domain`: Check a domain only (no local part; anything containing "@" is refused): disposable (the domain or a parent domain is on the disposable-email-domains list), free webmail provider, look-alike (confusable) domain and a typo suggestion. Use this when you do not need the part before the @. Read-only. Same engine, keys and limits as GET /v1/domain/{domain}.
- `check_email`: Check one email address against the disposable-email-domains list (CC0): disposable (domain or a parent domain is listed), role address (info@, admin@ …), free webmail provider, look-alike (confusable) domain, practical syntax, and a one-character typo suggestion for big webmail domains. List-based and offline: no MX/DNS lookup, so a valid format does not mean the mailbox exists. The address is sent in a POST body and not stored or logged. Read-only. Same engine, keys and limits as POST /v1/check.
- `get_meta`: Return the service version and build, the disposable-list version, domain and allowlist counts, the last refresh time, the upstream source and licence (CC0), and the current limits. Does not count as a check. Read-only. Same data as GET /v1/meta.
