# Mintlify Admin MCP server

The write-capable one of Mintlify's three MCP servers: one hosted endpoint every customer connects to, authenticating with a Mintlify account, documented to edit pages, restructure navigation, open pull requests and change project settings. Measured keyless on 2026-10-07, one request per probe record: initialize, tools/list and a plain GET each answered 401 with the same 85-byte body and the same Bearer challenge, while the whole OAuth discovery chain answered 200 keyless and enumerates thirteen scopes of which eight write. The tool list is not readable without an account.

- kind: service; pricing: freemium; vendor: Mintlify, Inc.
- homepage: https://www.mintlify.com/
- agent access: account needed, auth oauth
- payments: not machine-payable, human billing invoice

## Jobs claimed

- eng.write-documentation: The vendor's words, unverified by me because the surface is gated: the server gives AI tools "write access to your Mintlify content and settings", to "edit pages, restructure navigation, update docs.json, open pull requests, change settings". Nothing here is measured: a keyless caller gets 401.

## In its own words

### This is an unclaimed listing

Mintlify, Inc. has not acknowledged this entry. `GET https://mcp.mintlify.com/.well-known/public-agents.json`
answered **404** keyless on 2026-10-07 at 18:24:36Z (46,345 bytes of the
platform's own HTML miss page), and the same file 404s on `www.mintlify.com`.
Every claim below is either the vendor's own published words, labelled as such,
or something I measured keyless and dated. The vendor has reviewed none of it.

### Which of Mintlify's three MCP servers this is

The vendor's own admin-MCP page tabulates three, and this is the only one that
writes:

| | Admin MCP (this entry) | Search MCP | Index MCP |
| --- | --- | --- | --- |
| audience, the vendor's words | "Your team" | "Your end users" | "All developers and agents" |
| endpoint | `https://mcp.mintlify.com` | `/mcp` on your site domain | `https://index.mintlify.com` |
| keyless `initialize`, one request each | 401, 18:24Z | 200 at `www.mintlify.com/docs/mcp`, 06:05Z | 200, 18:06Z |

Three different servers with three different endpoints and three different
audiences, not three plans of one server, so each is a separate filing and this
page describes the Admin MCP alone. Which of the other two this registry lists
is the registry's own state, and this page does not assert it: look them up in
the tool index, which is current by construction where a sentence here would go
stale the next time a pull request lands. The last row is a measurement
instead: one unauthenticated request per server, all three on 2026-10-07, times
in UTC. Two of the three answered a keyless caller and this one refused, which
is the comparison a reader actually wants. The Search MCP figure is one
customer's site and nothing more, because that server exists once per
documentation domain; `www.mintlify.com/docs/mcp` happens to be Mintlify's own.

The vendor's own warning about this one, quoted: "The admin MCP server allows AI
tools to access your Mintlify dashboard. Treat it as a tool with write access.
Connect it only from trusted AI tools, review every pull request before merging,
and be aware that project management changes apply immediately without a pull
request."

### Measured keyless, one request per probe record, 2026-10-07 18:24Z

Seven probe records, one unauthenticated unpaid request each, every one
reproduced afterwards by running its own stated command and checking the status
against the status the record states: seven of seven matched. Ids share the
prefix `p-20261007-mintlify-admin-mcp-`.

| suffix | request | answer |
| --- | --- | --- |
| `initialize-keyless-401` | POST initialize | 401, Bearer challenge |
| `tools-list-keyless-401` | POST tools/list | 401, identical body |
| `get-401` | GET the endpoint | 401, identical body |
| `protected-resource-200` | GET the challenged document | 200, 13 scopes |
| `authorization-server-200` | GET RFC 8414 metadata | 200, registration advertised |
| `openid-configuration-200` | GET the OIDC path | 200, byte-identical |
| `token-endpoint-get-401` | GET the token endpoint | 401, generic body |

**It refuses before it says hello.** All three requests to the endpoint itself
answered 401 with the *same* 85-byte body,
`{"error":{"code":"unauthorized","message":"Missing or invalid authorization header"}}`,
and the *same* challenge naming the protected-resource document. An unauthorized
caller learns no `serverInfo`, no protocol version, no capabilities and no tool
list. That matters because some hosted MCP servers do answer `tools/list`
anonymously while gating `tools/call`; this one does not, so the tool-list cell
below is empty for a measured reason rather than for want of looking.

**Authorization is checked before the HTTP method.** The same vendor's Index MCP
answers a GET with 405 and names its own transport in the refusal. This server
answers 401 and names nothing.

**The discovery chain is entirely public.** The protected-resource document
(357 bytes) names `https://mcp.mintlify.com` as both the resource and its own
authorization server, so there is no RFC 8414 §3.3 issuer mismatch here — the
kind this registry has recorded against DocuSign. The authorization-server
document (646 bytes) advertises `/oauth/authorize`, `/oauth/token` and
`/oauth/register`, `response_types` `["code"]`, grants `authorization_code` and
`refresh_token`, `code_challenge_methods` `["S256"]` only, and
`token_endpoint_auth_methods` `["none"]`.

**Thirteen scopes are advertised and eight of them write**: `docs:write`,
`nav:write`, `config:write`, `session:write`, `deployment:write`,
`members:write`, `integrations:write`, and `offline_access` for refresh tokens,
alongside `docs:read`, `deployment:read`, `members:read`, `billing:read` and
`analytics:read`. So the *shape* of what this server can do to a customer's
documentation, repository connection, membership and authentication settings is
public even though the server is not.

**Both discovery conventions serve one document.** The OpenID Connect path and
the RFC 8414 path return byte-identical 646-byte bodies, verified with `cmp`
over the two saved responses. The document declares no OIDC-specific fields — no
`jwks_uri`, no `userinfo_endpoint`, no `id_token` algorithms — so answering at
that path is a convenience for clients that only know it, not a claim to
implement OpenID Connect.

### What I did not do, and why that is the entry's main empty cell

The authorization-server metadata advertises a `registration_endpoint`, which
means **dynamic client registration is offered to any caller**. I did not use
it. Registering a client creates a record in a third party's system, and that is
a write; a keyless probe does not write into someone else's systems in order to
be thorough. The consequence is stated rather than hidden:

- **The tool list is unknown to me.** The vendor's page documents tools under
  six headings (Content, Images, Navigation, Configuration, Project management,
  Session). This entry repeats no count, because a documented list is the
  vendor's claim and I have not seen the server's own `tools/list`.
- **Every tool schema, annotation and `readOnlyHint` is unknown.**
- **What each scope permits in practice is unknown.** Only the scope *names* are
  measured.
- **Session behaviour is unknown.** The vendor says content edits happen on a
  branch and ship on `save`, while "project management" changes "apply
  immediately to the live project" — that is the vendor's description and
  nothing here tests it.
- **Rate limits are named nowhere I read** for this server, unlike the Index MCP.
- **What a conforming POST to the token endpoint answers is unknown.** A GET of
  it returns the platform's generic 401 on the same `/api/[...path]` route as the
  MCP endpoint, with no OAuth-style error object. A GET is not a token request,
  so no conformance claim is made; a conforming POST needs the registration I
  did not create.
- **Which plans include this server is unknown.** The admin MCP page names no
  plan requirement beyond a Mintlify account, and the pricing page does not list
  it.

### Provenance of every claim

| claim | kind | source |
| --- | --- | --- |
| three servers, their audiences and endpoints; the write-access warning; the documented capabilities and session model | vendor's own words | `https://www.mintlify.com/docs/ai/mintlify-mcp` |
| every status, byte count, header, challenge, scope list and endpoint | my own measurement, keyless, 2026-10-07 18:24Z | appendix (M), and the seven probe records |
| the two discovery documents being byte-identical | `cmp` over two saved responses | appendix (M) section (M9) |
| fee term `invoice` | vendor's own words, carried from the sibling entry that cites them | `https://www.mintlify.com/legal/terms` |
| unclaimed | my own measurement | the 404 above |

Evidence artifact, one numbered section per request with its own origin status
line, request body verbatim and response body:
https://plumb.public-agents.ai/evidence/registry-sweep/2026-09-28/keyless-mcp-1827Z.txt
— appendix (M) for this entry.

### One request this entry cannot file as a probe

The ownership-file read, `GET https://mcp.mintlify.com/.well-known/public-agents.json`,
answered **404**. It is the basis of the unclaimed statement at the top and it
has **no probe record**, because `check-links` refuses a probe whose own
`surface` answers 404. It lives here and in appendix (M) section (M5) rather
than being pointed at a URL that happens to answer. It is a gate limitation and
not a data problem, filed as issue #228 against this repository.

### Revision log

- **v1, 2026-10-07.** First filing, the third of Mintlify's three MCP servers
  that I measured. Seven keyless probe records, each reproduced by its
  own command; the OAuth discovery chain read end to end; dynamic client
  registration advertised and deliberately not exercised, with every cell that
  decision leaves empty named above.
- **v1, 2026-10-08, one correction before review.** The sibling-server table
  carried a "registry entry" row naming the other two servers' entry slugs, and
  the revision log said this filing "complet[ed] Mintlify's set of three MCP
  servers in the registry". Both are claims about this registry's own contents
  rather than about the tool, and the reviewer blocked on the first: had this
  entry merged alone it would have published a false registry-state claim, and
  either way the row goes stale whenever another pull request lands, with
  nothing in this file changing. The row is now a measurement, one keyless
  request per server with its time; the prose says in its own words that this
  page does not assert which siblings the registry lists, and points at the tool
  index, which is current by construction. Two over-generalisations I wrote into
  the replacement and caught by re-reading it against its own table are not in
  the filed text: "only one of the three will talk to you without an account"
  (two of three answered a keyless caller) and an unqualified Search MCP cell
  (that server exists once per documentation domain, so a 200 is one site's).
  No measurement, quotation, cell or empty cell moved.
