### 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

- 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: enrich_preview (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_premium_access (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); resolve_company (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 538 tokens to load every tool

- pass `stability.changes`: 1 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

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

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

### Tool changes

- 2026-10-30 `verify_email_preview` added
  - Free keyless email-deliverability preview. Grades ONE address in full (real output): syntax, MX / implicit-MX routing, email provider, SPF/DMARC posture, disposable / role / free-provider flags, a derived edit-distance typo did-you-mean, and an A-F deliverability grade — no SMTP ping, no account. Any additional addresses return only {deliverable, grade}. A real taste of the paid /email/verify, which returns the full per-email record for up to 100 addresses in one x402 call — call get_premium_access for the metered endpoint.

## Tools (4)

- `enrich_preview`: Free keyless DNS/RDAP enrichment preview for a company domain: email provider (from MX), SaaS detected from DNS TXT, domain age + registrar (RDAP). A real taste of the paid /company/enrich, which adds a bounded site crawl (firmographics, contacts, social), tech-stack fingerprint, office address, legal registration (VAT / company number) and the live multi-ATS hiring block — call get_premium_access for the full record.
- `get_premium_access`: Return the paid x402 rail: the metered depth layers (hosted 10-ATS search, normalized compensation, per-company hiring-intent signal, company enrichment, email deliverability) with exact prices (USDC on Base), the pay-to address, and how the 402 flow works. No account; an x402-aware client pays inline from the agent's wallet.
- `resolve_company`: Resolve which applicant-tracking system a company uses and its board token, from a bare slug or domain. Returns {platform, token, via}. Free.
- `verify_email_preview`: Free keyless email-deliverability preview. Grades ONE address in full (real output): syntax, MX / implicit-MX routing, email provider, SPF/DMARC posture, disposable / role / free-provider flags, a derived edit-distance typo did-you-mean, and an A-F deliverability grade — no SMTP ping, no account. Any additional addresses return only {deliverable, grade}. A real taste of the paid /email/verify, which returns the full per-email record for up to 100 addresses in one x402 call — call get_premium_access for the metered endpoint.
