Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Read deSEC domains, DNSSEC keys, zone files and RRsets; create or replace one DNS record set.
These three are never merged into one score: opinions, measurements and popularity are different things.

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
desec_list_domainsList the DNS domains (zones) in this deSEC account, newest first, with creation and last-published times and minimum TTL. DNSSEC keys are omitted here (see desec_get_domain). Use owns_qname to find which of your domains is responsible for a DNS name (for example before adding a r
desec_get_domainOne domain with its DNSSEC key material: the DNSKEY and the DS records to publish at the registrar for the chain of trust, plus minimum TTL and publication times. GET /domains/{name}/.
desec_export_zonefileThe whole zone as a plain-text BIND-format zonefile (all RRsets except DNSSEC types). Handy as a backup before changing records. Counts as an expensive deSEC operation (300/min). GET /domains/{name}/zonefile/.
desec_list_rrsetsList the DNS records of a domain as RRsets (all records of one name and type, sharing one TTL), newest first. Filter by type and/or subname. Up to 500 per page. GET /domains/{name}/rrsets/.
desec_get_rrsetOne RRset by subname and type, e.g. the A records of "www" or the MX records of the apex. GET /domains/{name}/rrsets/{subname}/{type}/.
desec_create_rrsetWRITE: create ONE new RRset (a set of DNS records of one type at one name) in a domain. It goes live in DNS immediately and a wrong record can take a site or mail offline. Fails if an RRset with this subname and type already exists (use desec_replace_rrset for that) or if a CNAME
desec_replace_rrsetWRITE (overwrites): set ONE RRset to exactly the given TTL and records, creating it if it does not exist and REPLACING all its current records if it does. It goes live in DNS immediately; a wrong value can take a site or mail offline. The previous RRset is read first and returned

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 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 –, and the latest version (1.22.3) 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 in developer mode.

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your deSEC credentials.

read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Pro (per user) | $9/mo or $90/yr (2 months free) | Unlimited* |
\*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to support@usefulapi.io.
Pro covers this server only. Subscribe with desec_upgrade (it returns a Stripe Checkout link). Cancel any time with desec_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running desec_upgrade before then undoes the cancel.
