How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 19 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability75
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 3291 tokens (~173/item across 19 items; 19 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management73
- Stability observed for 22 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 6 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "delete_domain" implies "delete" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 19 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities20
- Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28. See how to fix → Fail

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
add_acme_challenge ~203
Publish a Let's Encrypt DNS-01 challenge: creates a TXT record at _acme-challenge.<label>.<domain> with the token your ACME client printed. Use this to get a certificate without exposing port 80 (for example for a wildcard cert, or a host behind NAT). DNS propagates within seconds, then tell your ACME client to continue. For a normal public web server, HTTP-01 validation needs no DNS record at all.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | – | Which domain to act under: 'makes.fyi' (the default) or 'agentdomains.co'. The same label can exist under each, so pass this whenever you are not using the default. |
| label | string | yes | The subdomain label, without the domain suffix (e.g. 'myapp' for myapp.makes.fyi). |
| value | string | yes | The challenge token from your ACME client, published verbatim as the TXT value. |
No output schema declared.
No examples provided.
add_dns_record ~276
Add a DNS record to a subdomain you already own. Use type A or AAAA to point at an IP address, CNAME to point at another hostname, or TXT for verification strings. Adding a record does not replace existing ones; use delete_record to remove a single one. Refused with a 409 while the label carries a forward or a proxy (they own the hostname) — call remove_forward or remove_proxy first, or add the record on a sub-label via 'host', which is a different hostname and unaffected.
| Name | Type | Req | Description |
|---|---|---|---|
| content | string | yes | Record value: an IP for A/AAAA, a hostname for CNAME, the string for TXT. |
| domain | string | – | Which domain to act under: 'makes.fyi' (the default) or 'agentdomains.co'. The same label can exist under each, so pass this whenever you are not using the default. |
| host | string | – | Optional extra sub-label under the name (e.g. 'www' creates www.myapp.makes.fyi). Omit for the name itself. |
| label | string | yes | The subdomain label, without the domain suffix (e.g. 'myapp' for myapp.makes.fyi). |
| type | string | yes | Record type: A, AAAA, CNAME, or TXT. |
No output schema declared.
No examples provided.
attach_email ~66
Attach an email address to the account and send it a verification link. A human must click that link within 30 days or the provisional account and its domains are deleted. Use this right after signup.
| Name | Type | Req | Description |
|---|---|---|---|
| string | yes | The email address to attach and send the verification link to. |
No output schema declared.
No examples provided.
check_availability ~143
Check whether a subdomain label is free before claiming it. Requires no API key. Returns { label, domain, fqdn, available, reason } where reason is 'available', 'taken', or 'invalid' (with a 'detail' explaining why the label is not usable).
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | – | Which domain to act under: 'makes.fyi' (the default) or 'agentdomains.co'. The same label can exist under each, so pass this whenever you are not using the default. |
| label | string | yes | The subdomain label, without the domain suffix (e.g. 'myapp' for myapp.makes.fyi). |
No output schema declared.
No examples provided.
claim_domain ~348
Register a subdomain (label.makes.fyi or label.agentdomains.co) on this account, optionally creating its first DNS record in the same call. An email is required the first time an account registers a name — pass 'email' here or call attach_email first; the name is reaped if that email is not confirmed within 30 days. Returns the fqdn and, when a record was requested, the created record. The claim and its first record succeed or fail together: if the record is malformed (400) or the provider refuses it (503) the label is NOT claimed, so fix the record and call again. Re-claiming a name this account already holds answers 409 with owned:true — that means carry on using it, not pick another label.
| Name | Type | Req | Description |
|---|---|---|---|
| content | string | – | Value for that record (an IP for A/AAAA, a hostname for CNAME, text for TXT). |
| domain | string | – | Which domain to act under: 'makes.fyi' (the default) or 'agentdomains.co'. The same label can exist under each, so pass this whenever you are not using the default. |
| string | – | Required on the account's first registration if no email is attached yet. Sends a confirmation link. | |
| host | string | – | Optional extra sub-label for the record (e.g. 'www' gives www.myapp.makes.fyi). |
| label | string | yes | The subdomain label, without the domain suffix (e.g. 'myapp' for myapp.makes.fyi). |
| type | string | – | Optional DNS record to create immediately: A, AAAA, CNAME, or TXT. |
No output schema declared.
No examples provided.
delegate_nameservers ~182
Delegate the subdomain to your own nameservers, handing you full control of it and everything beneath it (your own records, MX, deeper sub-domains). AgentDomains stops answering for the name, so its existing records, forwards, and proxies no longer apply. Supply at least two nameservers.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | – | Which domain to act under: 'makes.fyi' (the default) or 'agentdomains.co'. The same label can exist under each, so pass this whenever you are not using the default. |
| label | string | yes | The subdomain label, without the domain suffix (e.g. 'myapp' for myapp.makes.fyi). |
| nameservers | array | yes | Your nameserver hostnames, e.g. ['ns1.yourdns.com', 'ns2.yourdns.com']. At least two. |
No output schema declared.
No examples provided.
delete_account ~194
DESTRUCTIVE AND IRREVERSIBLE, AND THE LARGEST ONE HERE: delete the whole AgentDomains account and invalidate its API key, which cannot be recovered or reissued — every later tool call fails with a 401 until a new signup. Without force it REFUSES while the account still holds names, answering 409 with the list of them; that refusal is a safety net, so show the list to the user and get an explicit yes before retrying. With force:true those names are deleted too: they stop resolving at once and are released for anyone else to claim. Only ever call this when the user has asked to close the account itself — never as cleanup after a task, and never to 'start fresh' on your own initiative.
| Name | Type | Req | Description |
|---|---|---|---|
| force | boolean | – | Delete the names the account still holds along with it. Without this the call is refused while any name remains, which is the intended default. |
No output schema declared.
No examples provided.
delete_domain ~153
DESTRUCTIVE AND IRREVERSIBLE: permanently delete a subdomain and every DNS record, forward, and proxy attached to it. The hostname stops resolving immediately and the label is released for anyone else to claim. There is no undo and no recovery. Only call this when the user has explicitly asked for this specific name to be deleted.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | – | Which domain to act under: 'makes.fyi' (the default) or 'agentdomains.co'. The same label can exist under each, so pass this whenever you are not using the default. |
| label | string | yes | The subdomain label, without the domain suffix (e.g. 'myapp' for myapp.makes.fyi). |
No output schema declared.
No examples provided.
delete_record ~212
DESTRUCTIVE: permanently remove ONE DNS record from a subdomain, keeping the name and every other record. Use this to undo a single record — a wrong IP, a spent ACME challenge — instead of delete_domain, which takes the whole name. The record_id is the 'id' field shown by get_domain (and returned by claim_domain and add_dns_record); it is not the record's name or content. The hostname stops resolving through that record immediately and there is no undo.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | – | Which domain to act under: 'makes.fyi' (the default) or 'agentdomains.co'. The same label can exist under each, so pass this whenever you are not using the default. |
| label | string | yes | The subdomain label, without the domain suffix (e.g. 'myapp' for myapp.makes.fyi). |
| record_id | string | yes | The record's 'id' as reported by get_domain — not its name, type, or content. |
No output schema declared.
No examples provided.
get_domain ~108
Show one subdomain in full: its fqdn, DNS records, forward or proxy configuration, and delegation state.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | – | Which domain to act under: 'makes.fyi' (the default) or 'agentdomains.co'. The same label can exist under each, so pass this whenever you are not using the default. |
| label | string | yes | The subdomain label, without the domain suffix (e.g. 'myapp' for myapp.makes.fyi). |
No output schema declared.
No examples provided.
list_domains ~37
List every subdomain on this account, with each one's DNS records and whether it is forwarding, proxying, or delegated to external nameservers.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
manage_billing ~75
Get a Stripe billing-portal link for a Pro account: update the card, see invoices, switch between monthly and yearly, or cancel. A human must open it. Cancelling keeps Pro to the end of the paid period and never deletes a name. Answers 409 if the account has never subscribed (use upgrade_to_pro).
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
remove_forward ~106
Stop forwarding a subdomain. The name itself stays registered on the account; only the redirect is removed.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | – | Which domain to act under: 'makes.fyi' (the default) or 'agentdomains.co'. The same label can exist under each, so pass this whenever you are not using the default. |
| label | string | yes | The subdomain label, without the domain suffix (e.g. 'myapp' for myapp.makes.fyi). |
No output schema declared.
No examples provided.
remove_proxy ~117
Stop reverse-proxying a subdomain, so the edge no longer serves the backend or terminates TLS for it. The name stays registered on the account.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | – | Which domain to act under: 'makes.fyi' (the default) or 'agentdomains.co'. The same label can exist under each, so pass this whenever you are not using the default. |
| label | string | yes | The subdomain label, without the domain suffix (e.g. 'myapp' for myapp.makes.fyi). |
No output schema declared.
No examples provided.
set_forward ~362
Forward (HTTP-redirect) a subdomain to another URL. Claims the label first if you do not own it yet, in which case an email may be required exactly as for claim_domain. Defaults to a 302 temporary redirect that preserves the request path and query. HTTPS at the edge is handled for you. A forward TAKES OVER the hostname: any A/AAAA/CNAME record on the label itself is deleted as part of this call and returned in 'replaced_records' — report those to the user, since the name no longer points where it did. Records on a sub-label (www.myapp.makes.fyi) and TXT records are untouched. If the forward fails to come up the replaced records are restored, with new ids.
| Name | Type | Req | Description |
|---|---|---|---|
| cloak | boolean | – | Keep the AgentDomains hostname in the address bar and load the target inside a frame. Discouraged — breaks many sites. |
| domain | string | – | Which domain to act under: 'makes.fyi' (the default) or 'agentdomains.co'. The same label can exist under each, so pass this whenever you are not using the default. |
| string | – | Email, if this call also claims a new name on an account without one. | |
| label | string | yes | The subdomain label, without the domain suffix (e.g. 'myapp' for myapp.makes.fyi). |
| permanent | boolean | – | Use a 301 permanent redirect instead of the default 302 temporary one. |
| preserve_path | boolean | – | Append the incoming path and query to the target. Defaults to true; set false to always land on the target root. |
| target | string | yes | Destination URL, including scheme (e.g. https://example.com/docs). |
No output schema declared.
No examples provided.
set_proxy ~301
Serve a backend at this subdomain through the AgentDomains edge, which terminates TLS with its own certificate — this is how you get working HTTPS on an origin that has no certificate of its own (a bare IP-less PaaS host, a tunnel, an internal box). Unlike a forward, the URL stays on your domain and the response is proxied, not redirected. Claims the label first if needed. Like a forward, a proxy TAKES OVER the hostname: A/AAAA/CNAME records on the label itself are deleted and returned in 'replaced_records', while sub-label and TXT records are untouched. A proxy and a forward are mutually exclusive on one label. Caveat: apps that hardcode their own hostname (OAuth callbacks especially) may need your new hostname registered on their side.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | – | Which domain to act under: 'makes.fyi' (the default) or 'agentdomains.co'. The same label can exist under each, so pass this whenever you are not using the default. |
| string | – | Email, if this call also claims a new name on an account without one. | |
| label | string | yes | The subdomain label, without the domain suffix (e.g. 'myapp' for myapp.makes.fyi). |
| origin | string | yes | Backend hostname to proxy to, without a scheme (e.g. myapp.fly.dev). Must be a hostname, not an IP. |
No output schema declared.
No examples provided.
signup ~111
Create a new AgentDomains account and get an API key. Requires no existing key. IMPORTANT: the returned api_key is shown ONCE and is never retrievable again — you must store it immediately (save it to ~/.agentdomains/config.json or set AGENTDOMAINS_API_KEY) or the account is lost. The account is provisional: attach and confirm an email within 30 days (see the attach_email tool) or it is deleted along with its domains. This endpoint is rate-limited per IP address.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
upgrade_to_pro ~180
Get a Stripe checkout link for AgentDomains Pro: 100 names instead of the free 10, names never released for being unreachable, and priority email support, for $5/month (or $48/year with interval 'year'). Use this when a claim is refused because the account is at its name limit and the user wants more. It only returns a link and never charges anything: a human must open the URL and pay. Show them the url and say what Pro costs; do not open it or pay on their behalf. If the account is already Pro the answer has kind:'portal' and a link to manage the subscription instead. Answers 404 'billing is not enabled' on a server that does not sell Pro.
| Name | Type | Req | Description |
|---|---|---|---|
| interval | string | – | Billing interval: 'month' ($5, the default) or 'year' ($48). |
No output schema declared.
No examples provided.
whoami ~117
Show the current account: id, state, attached email and whether it is verified, domains used, and which domains are available to claim under. When quotas are disabled the response omits 'quota' and says unlimited:true; 'max_subdomains' is the separate hard cap on how many names one account may hold at once (10 on the free plan, 100 on Pro). 'plan' is 'free' or 'pro'; when Pro is on sale a free account also gets an 'upgrade' hint (see upgrade_to_pro).
Input schema present but exposes no named parameters.
No output schema declared.

What is the AgentDomains MCP server?
AgentDomains is an MCP server listed in the public MCP registry as io.github.tashfeenahmed/agentdomains-mcp. Free domains under makes.fyi or agentdomains.co for the sites and APIs AI agents build. This page covers its hosted endpoint (https://mcp.agentdomains.co).
Is the AgentDomains MCP server safe to use?
AgentDomains scores 70 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the AgentDomains MCP server expose?
AgentDomains exposes 19 tools: check_availability, signup, whoami, attach_email, claim_domain, and 14 more. Their descriptions and schemas cost roughly 3,291 tokens of context every time the server is loaded.
Does the AgentDomains MCP server require authentication?
No. We connected to AgentDomains without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the AgentDomains MCP server still maintained?
AgentDomains is still listed as active in the MCP registry. We last reached this channel on 22 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
