Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.
ns1_list_zonesList the DNS zones in the account: name, id, TTL/SOA settings, primary/secondary setup, linked zones and tags. If next_page is not null, call again with its after/offset to get more. GET /v1/zones.
ns1_get_zoneOne zone with its settings and its record list (each record: domain, type, TTL, short answers, linked/tier info). Large zones are paged: if next_page is not null, call again with its after/offset to get the next records. TSIG secrets are redacted. GET /v1/zones/{zone}.
ns1_get_recordOne DNS record by zone, domain and type: TTL, answers (with per-answer metadata), filter chain (traffic steering), linked record and region settings. GET /v1/zones/{zone}/{domain}/{type}.
ns1_searchSearch the account's zones and records by name (substring match). Returns matching zones and/or records with their answers when expand is true. GET /v1/search.
ns1_list_monitoring_jobsList the account's NS1 monitoring jobs (health checks that feed traffic steering): id, name, type, regions, frequency, rules, current status, active flag and notify list id. Request header values and credentials are redacted. GET /v1/monitoring/jobs.
ns1_get_monitoring_jobOne monitoring job by id with its configuration, rules, regions and status. Header values and credentials are redacted. GET /v1/monitoring/jobs/{id}.
ns1_list_notify_listsList the notifier lists that monitoring alerts are sent to: id, name and the notifier types and labels (email, Slack, PagerDuty, webhook). Notifier settings (webhook URLs, tokens, service keys, addresses) are redacted. GET /v1/lists.
ns1_list_data_sourcesList the data sources (connections to third-party monitoring or custom push sources used for traffic steering): id, name, source type, status and their feeds. Connection settings and credentials are redacted. GET /v1/data/sources.
ns1_get_data_sourceOne data source by id with its feeds. Connection settings and credentials are redacted. GET /v1/data/sources/{id}.
ns1_list_data_feedsList the feeds of one data source (each feed is one monitored item, e.g. one server's health) with id, name and settings. GET /v1/data/feeds/{source_id}.
ns1_get_data_feedOne data feed of a source by id. GET /v1/data/feeds/{source_id}/{feed_id}.
ns1_get_account_summaryThe account's subscription, resources and utilization (queries, records, filter chains, monitors, ... against the plan limits). GET /v1/account/summary.
ns1_get_usage_statsDNS query counts for the whole account, one zone, or one record (give zone, or zone + domain + type). period is 1h, 24h or 30d; aggregate, expand, limit and after apply to the account and zone levels only (a record takes just period). If next_page is not null, call again with its
ns1_get_qps_statsCurrent queries per second for the whole account, one zone, or one record (give zone, or zone + domain + type). GET /v1/stats/qps[/{zone}[/{domain}/{type}]].
ns1_get_billing_recordsHow many DNS records the account uses against its plan limit in the current billing cycle. GET /billing-usage/v1/records.
ns1_get_billing_queriesBillable DNS query usage between two Unix timestamps. GET /billing-usage/v1/queries?from=&to=.
ns1_create_recordWRITE: creates ONE new DNS record and CHANGES LIVE DNS for that name as soon as NS1 serves it; a wrong answer can take a site or mail offline. Plain records only (A, AAAA, ALIAS, CAA, CNAME, MX, PTR, SRV, TXT; no NS/SOA, no traffic-steering filters or metadata). Refuses when the
ns1_update_recordWRITE: changes ONE existing DNS record and CHANGES LIVE DNS for that name immediately. Giving answers REPLACES all current answers of the record (send the complete new set); giving only ttl changes just the TTL. Plain records only (A, AAAA, ALIAS, CAA, CNAME, MX, PTR, SRV, TXT):

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed yesterday, and the latest version (1.26.1) reached the registry yesterday.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
