Claude Code: deny. ### `cancel_registration` - The name "cancel_registration" says "cancel": a word for removing or ending something. Description, as the server wrote it: ```untrusted-server-text Prepare cancelling a registration made in the last few days (the registry's add grace period, about 5 days). Once approved the domain is deleted and the payment refunded. ``` ### `cancel_transfer` - The name "cancel_transfer" says "cancel": a word for removing or ending something. Description, as the server wrote it: ```untrusted-server-text Prepare cancelling a transfer: direction "in" stops one coming to Nymwell (the payment is refunded), "out" stops a domain leaving for another registrar. Needs approval. ``` ## Can't be undone (3) Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask. ### `list_transfers` - The name "list_transfers" says "list": a word for reading. - The description's first verb is "transfer": a word for a change that another call does not undo. Description, as the server wrote it: ```untrusted-server-text Transfers into Nymwell for this organization and where each one is. ``` ### `purchase_domain` - The name "purchase_domain" says "purchase": a word that usually means money moves, which cannot be taken back. Description, as the server wrote it: ```untrusted-server-text Start paying for a quote (registration, renewal or transfer). Returns a checkout_url: give it to the person, who pays once; paying is their approval. The registrar call (and, for a registration, the DNS records you pass) then runs on its own. Poll get_order for the result. An agent never pays by itself. ``` ### `resend_contact_verification` - The name "resend_contact_verification" says "resend": a word for sending, and what is sent cannot be taken back. - Tag outbound: The name "resend_contact_verification" says "resend": it sends or publishes something to other people. Description, as the server wrote it: ```untrusted-server-text Send the ICANN verification email again for one verification_id from list_unverified_contacts. ``` ## Changes things (11) Creates or changes something that can be changed back. Claude Code: ask. ### `apply_dns_preset` - The name "apply_dns_preset" says "apply": a word for a change. Description, as the server wrote it: ```untrusted-server-text Prepare DNS records for a domain this organization already manages. It creates a change set a person approves in the console; nothing is written before that. ``` ### `change_domain_service` - 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 Prepare a DNSSEC, URL forwarding, email forwarding or vanity nameserver change. Needs approval. data: dnssec {key_tag, algorithm, digest_type, digest} (delete: digest); url_forwarding {host, forwards_to, type: masked|redirect|302, title?, meta?} (delete: host); email_forwarding {email_box, email_to} (delete: email_box); vanity_nameservers {hostname, ips} (delete: hostname). ``` ### `get_quote` - The name "get_quote" says "get": a word for reading. - The description's first verb is "lock": a word for a change. Description, as the server wrote it: ```untrusted-server-text Lock the exact price for one domain: action "register" (default) for an available name, "renew" for a domain this organization holds, or "transfer" to bring one from another registrar (adds one year; the owner then submits the auth code in the console). Valid for 40 minutes; purchase_domain charges exactly this. ``` ### `request_auth_code` - The name "request_auth_code" says "request": a word for a change. Description, as the server wrote it: ```untrusted-server-text Prepare unlocking a domain and revealing its transfer auth code, to move it to another registrar. After approval the code is shown once to the approving person; an agent never sees it. Not possible within 60 days of a registration or transfer. ``` ### `screen_domains` - 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 Fast first pass over many names: is there a registration record, since when, with which registrar, is it parked for sale. Uses public RDAP and DNS, so it works before any registrar is configured. It is NOT availability: no_record still has to be confirmed with search_domains or get_quote after nymwell_status reports a live registrar. No sign-in needed. ``` ### `set_auto_renew` - The name "set_auto_renew" says "set": a word for a change. Description, as the server wrote it: ```untrusted-server-text Turn Nymwell's auto-renew on or off for a domain. When it is on and the workspace has a saved card, Nymwell charges that card for a one-year renewal from 14 days before expiry (retrying 7, 3 and 1 day before); without a card it sends reminders instead. The answer says which applies. The registrar's own auto-renew always stays off. ``` ### `set_contacts` - The name "set_contacts" says "set": a word for a change. Description, as the server wrote it: ```untrusted-server-text Prepare a contact change. registrant is required (it is the legal holder); admin, tech and billing are optional. A new registrant must confirm by email within 15 days or the domain stops resolving. Needs approval. ``` ### `set_nameservers` - The name "set_nameservers" says "set": a word for a change. Description, as the server wrote it: ```untrusted-server-text Prepare a nameserver change: 2 to 13 hostnames, or "default" to return to Nymwell DNS. Pointing elsewhere means the records in Nymwell stop applying. Needs approval. ``` ### `stage_dns_change` - 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 Prepare DNS changes (create, update, delete) for review. Nothing is written until an owner or admin approves; then Nymwell applies them at the registrar in order. For update and delete, pass record_id from list_dns_records when a name has more than one record of that type. ``` ### `suggest_domains` - 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 Names a live registrar can sell now that fit a keyword, with prices (registration inventory only). Sandbox suggestions are refused; use screen_domains until nymwell_status reports a live registrar. No sign-in needed. ``` ### `update_domain_settings` - The name "update_domain_settings" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text Prepare a WHOIS privacy or transfer lock change. An owner or admin approves it in the console before the registrar is touched. ``` ## Only reads (15) Looks things up and changes nothing. Claude Code: allow. ### `get_domain` - The name "get_domain" says "get": a word for reading. - Tag private-data: The description's first sentence says "contact": it reads contacts. Description, as the server wrote it: ```untrusted-server-text Live state of a domain this organization holds through Nymwell: expiry, renewal price, transfer lock, WHOIS privacy, registry locks, nameservers, contact verification and any transfer in progress. ``` ### `get_order` - The name "get_order" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Read where a purchase is: awaiting_payment, registering, registered, needs_attention or failed_refunded, with the DNS records that were created. workflow.state says what to do: in_progress or blocked = check again later; action_required = give workflow.action.url to the person; succeeded or failed = stop (failed carries workflow.error). ``` ### `get_registrant` - The name "get_registrant" says "get": a word for reading. - Tag private-data: The description's first sentence says "file": it reads files. Description, as the server wrote it: ```untrusted-server-text Whether this organization has its registrant on file. The customer is the legal holder of every domain; a signed-in person enters the registrant and accepts the terms in the console before the first registration or transfer. ``` ### `get_tld_info` - The name "get_tld_info" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text What an ending costs (registration, renewal, transfer) and its rules: allowed terms, days left to renew after expiry, WHOIS privacy, DNSSEC, HSTS preload. No sign-in needed. ``` ### `list_approvals` - The name "list_approvals" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text Changes waiting for a person to approve, and the ones already decided, each with workflow.state (action_required, in_progress, succeeded, failed).

Description, as the server wrote it: ```untrusted-server-text List the DNS presets purchase_domain and apply_dns_preset accept (Vercel, Netlify, GitHub Pages, Cloudflare Pages, Agent Lab Deploy, Google Workspace email). No sign-in needed. ``` ### `list_dns_records` - The name "list_dns_records" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List DNS records for a managed domain. refresh: true first pulls the records from the registrar (including ones changed outside Nymwell). ``` ### `list_domain_services` - The name "list_domain_services" says "list": a word for reading. - Tag private-data: The description's first sentence says "read" and "email": it reads mail. - Tag untrusted-input: The description's first sentence says "read" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it: ```untrusted-server-text Read Nymwell backend, database and provider-adapter readiness. ``` ### `search_domains` - The name "search_domains" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Check which domain names can be registered and what they cost from a live registrar (not DNS or RDAP). Pass exact domains, or a name plus endings. If Nymwell is not connected to a live registrar, this tool refuses sandbox data; use screen_domains for a public-record first pass. Prices are USD for the minimum term; get_quote gives the exact price for a chosen term. Each name has tier (standard or premium) when it can be registered, or reason (domain_unavailable, extension_not_supported, extension_disallows_registration) when it cannot. No sign-in needed. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `nymwell`: ```json { "permissions": { "allow": [ "mcp__nymwell__nymwell_status", "mcp__nymwell__list_domains", "mcp__nymwell__list_dns_records", "mcp__nymwell__list_invoices", "mcp__nymwell__list_members", "mcp__nymwell__list_audit_events", "mcp__nymwell__search_domains", "mcp__nymwell__get_order", "mcp__nymwell__list_dns_presets", "mcp__nymwell__get_tld_info", "mcp__nymwell__get_domain", "mcp__nymwell__list_domain_services", "mcp__nymwell__list_unverified_contacts", "mcp__nymwell__get_registrant", "mcp__nymwell__list_approvals" ], "ask": [ "mcp__nymwell__stage_dns_change", "mcp__nymwell__screen_domains", "mcp__nymwell__get_quote", "mcp__nymwell__purchase_domain", "mcp__nymwell__apply_dns_preset", "mcp__nymwell__suggest_domains", "mcp__nymwell__set_auto_renew", "mcp__nymwell__update_domain_settings", "mcp__nymwell__set_nameservers", "mcp__nymwell__set_contacts", "mcp__nymwell__request_auth_code", "mcp__nymwell__change_domain_service", "mcp__nymwell__list_transfers", "mcp__nymwell__resend_contact_verification" ], "deny": [ "mcp__nymwell__cancel_registration", "mcp__nymwell__cancel_transfer" ] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__nymwell__nymwell_status`: private-data - `mcp__nymwell__list_dns_presets`: private-data, untrusted-input - `mcp__nymwell__get_domain`: private-data - `mcp__nymwell__list_domain_services`: private-data, untrusted-input - `mcp__nymwell__list_unverified_contacts`: private-data, untrusted-input - `mcp__nymwell__get_registrant`: private-data - `mcp__nymwell__resend_contact_verification`: outbound
