Claude Code: deny. ### `apply_dns_fix` - The name "apply_dns_fix" says "apply": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Apply a DNS fix plan to a tracked domain by publishing records at the connected registrar. DESTRUCTIVE: it creates/updates/deletes DNS records. Two-step by design — first call get_dns_fix_plan, then pass its `connectionId` and `ops` here verbatim. The server re-derives the diff from the latest scan and rejects any op that no longer matches, so an agent can never apply arbitrary records. Requires an owner/admin API key with write or full scope. Re-scan afterward to confirm the fix. ``` ### `remove_domain` - The name "remove_domain" says "remove": a word for removing or ending something. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Stop monitoring a domain and delete it (and its scan history) from the account. DESTRUCTIVE and not reversible. Requires an owner/admin API key with write or full scope. (To ADD a domain, run scan_domain with this API key — authenticated scans auto-track the domain.) ``` ## Changes things (9) Creates or changes something that can be changed back. Claude Code: ask. ### `check_blocklists` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Check a domain (apex + MX-host IPs) against supported DNS blocklists and return listings, targets checked, and issues (authoritative-side queries; no public-resolver false positives). ``` ### `connect_inbox_placement` - The description's first verb is "store": a word for a change. Description, as the server wrote it: ```untrusted-server-text Store the org's seed-list inbox-placement provider + API key (provider: 'mailreach' or 'glockapps'; GlockApps also needs projectId). Enables start_inbox_placement_test. Requires an owner/admin API key with write or full scope. ``` ### `connect_snds` - The description's first verb is "store": a word for a change. Description, as the server wrote it: ```untrusted-server-text Store this org's Microsoft SNDS (Smart Network Data Services) automated-data-access key so InboxGuard syncs per-IP Outlook/Hotmail reputation daily. Get the key from the SNDS Automated Data Access page (https://sendersupport.olc.protection.outlook.com/snds/). Requires an owner/admin API key with write or full scope. Data appears within ~24h of the first sync. ``` ### `create_notification_channel` - The name "create_notification_channel" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Create a channel that InboxGuard alerts are delivered to: webhook (HMAC-signed), Slack, Microsoft Teams, PagerDuty, SMS, or email. Returns the channel id, and for kind=webhook the `signing_secret` used to verify deliveries. Requires an owner/admin API key with write or full scope. ``` ### `create_share_link` - The name "create_share_link" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Create a read-only public share link for a tracked domain's latest report (anyone with the URL can view it; no account). Returns a `token` and the public `url` (https://inboxguard.io/r/). Requires an owner/admin API key with write or full scope, on a plan that includes public reports. ``` ### `resolve_alert` - The name "resolve_alert" says "resolve": a word for reading. - The description's first verb is "mark": a word for a change. Description, as the server wrote it: ```untrusted-server-text Mark an alert resolved (or reopen it with resolved=false). Requires an API key with write/full scope. Resolving an already-resolved alert is a no-op. ``` ### `scan_domain` - The description's first verb is "run": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Run a full email-deliverability scan (SPF, DKIM, DMARC, MTA-STS, TLS-RPT, MX TLS, BIMI, DNS blocklists) for a domain and return a 0-100 score with per-check findings. A check can come back `not_applicable` (does not apply to this domain, e.g. MTA-STS on a domain with no MX — excluded from the score, not a failure) or `unverified` (could not be determined this scan, e.g. DKIM behind an ESP with a random per-tenant selector like Amazon SES Easy DKIM — never treat as a failure). `scoreSubtitle` explains the denominator when anything was excluded. Runs at your plan tier (full blocklist set on paid plans) and saves the scan to the domain history in your account. ``` ### `scan_domains_batch` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Queue an asynchronous batch scan of up to 50 domains and get a jobId immediately (avoids the 30s per-call limit). Poll get_scan_job with the jobId until status is succeeded/partial/failed to read per-domain scores. Requires an API key with write or full scope. These scans are NOT added to monitoring or saved to history. ``` ### `start_inbox_placement_test` - The name "start_inbox_placement_test" says "start": a word for a change. Description, as the server wrote it: ```untrusted-server-text Start a seed-list inbox-placement test. Returns a testId, the seed addresses to mail your campaign to, and (if the provider requires it) a header to insert. After sending to the seeds, poll get_inbox_placement_test for the Inbox/Spam/Missing verdict. Requires inbox-placement to be connected and an owner/admin API key with write or full scope. ``` ## Only reads (17) Looks things up and changes nothing. Claude Code: allow. ### `analyze_headers` - The name "analyze_headers" says "analyze": a word for reading. Description, as the server wrote it: ```untrusted-server-text Re-verify SPF, DKIM, DMARC, and ARC from a raw RFC 5322 email (full message or just the headers block). Returns InboxGuard's independent verdict (`ours`), the sender's own Authentication-Results (`theirs`), whether they `agree`, and parsed envelope/headers — useful for spotting forged or mismatched auth results. No account needed. ``` ### `get_deliverability_report` - The name "get_deliverability_report" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return a structured deliverability report for a tracked domain: the latest score + letter grade + `scoreSubtitle` (explains the denominator when a check was excluded, e.g. "80/100 · scored on 65 of 83 applicable points · 1 check unverified"), each check's status (pass/warn/fail/unverified/not_applicable — `not_applicable` means the check doesn't apply to this domain and `unverified` means it couldn't be checked this scan; neither is a failure), the top issues to fix, blocklist count, and DMARC policy. Includes `pdfUrl` — the same auth-gated endpoint that returns a branded one-page PDF (send your bearer token). Use this to summarize a domain's posture or hand a client a report. ``` ### `get_deliverability_score` - The name "get_deliverability_score" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return the overall deliverability score and letter grade for a domain (runs a fresh scan). ``` ### `get_dmarc_summary` - The name "get_dmarc_summary" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Summarize ingested DMARC aggregate (RUA) reports for a domain tracked in your InboxGuard account: report volume, pass rate, top sending sources, and the rua inbox to publish. The domain must already be added to the account, and the plan must include DMARC ingest. ``` ### `get_dns_fix_plan` - The name "get_dns_fix_plan" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Compute the exact DNS-record changes needed to fix a tracked domain's deliverability, based on its latest scan and the org's connected registrar (Cloudflare/Route 53/GoDaddy/Namecheap). Read-only — nothing changes. Returns the `ops` to pass verbatim to apply_dns_fix, plus `manualReview` items that need a human decision (SPF sender list, DKIM keys, BIMI logo). Requires the domain to be tracked, a scan to exist, and a registrar connection covering the zone. ``` ### `get_domain` - The name "get_domain" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Full detail for one tracked domain: the domain record, the latest scan with all per-check findings (spf, dmarc, dkim, ptr, mta_sts, tls_rpt, mx_tls, blocklist), recent score history, open/recent alerts, and Google Postmaster stats when connected. ``` ### `get_inbox_placement_status` - The name "get_inbox_placement_status" says "get": a word for reading.

Description, as the server wrote it: ```untrusted-server-text Org-wide deliverability rollup across every monitored domain: average score + overall grade, the grade distribution (how many domains are A/B/C/D/F/unscored), total open alerts, the domains needing attention (lowest score / open alerts first), and a per-client-group breakdown. Use this for an at-a-glance portfolio health summary across an agency or multi-domain account. ``` ### `get_scan_job` - The name "get_scan_job" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Poll an async batch scan started with scan_domains_batch: returns status (queued/running/succeeded/partial/failed), completed count, and per-domain results (domain, ok, score, grade) as they finish. ``` ### `get_snds_ip_stats` - The name "get_snds_ip_stats" says "get": a word for reading.
