# Verify an MCP-server claim via DNS TXT

`POST /mcp-servers/{id}/verify`

## Request

- Base URL: `https://api.mnemom.ai/v1`
- URL: `https://api.mnemom.ai/v1/mcp-servers/{id}/verify`
- Auth: one of:
  - API key in cookie `mnemom_session`
  - HTTP bearer

Looks up the origin domain apex TXT records over a fixed DoH resolver (Cloudflare 1.1.1.1) for `mnemom-verification=<token>`. Found → the claim is marked verified. Not found → `{claimed:false, reason:"txt-not-found"}` (HTTP 200; retry after DNS propagation). A successful verify by a different owner transfers control (anti-squat). The `{id}` path parameter is the URL-encoded server endpoint URL. Rate-limited per user and per IP.

## Path parameters

- `id` string, required

## Response `200`

Verification result (verified, or a friendly retryable not-found).

- object
  - `claimed` boolean, required
  - `verified_at` string, date-time, nullable
  - `reason` 'txt-not-found', nullable

## Other responses

- `400`: Bad request
- `401`: Authentication required
- `403`: Cross-origin write refused (`cross_origin_rejected`). A state-changing request that carries the browser session cookie must come from a first-party origin (`Origin`, or failing that `Referer`) and must not send a form-style body (text/plain, urlencoded, multipart) the operation does not declare. Bearer and API-key callers are never subject to this check.
- `404`: Resource not found
- `429`: Rate-limit exceeded. The global per-IP limiter (100 requests/minute, applied to every `/v1/*` route) rejected this request. Back off until the window resets — `Retry-After` carries the cooldown in seconds and `X-RateLimit-Reset` the absolute reset time.
- `500`: Server error — request was well-formed but the server failed to fulfill it. Typically a downstream dependency (DB / RPC / external API) returned an unexpected error.
- `503`: An upstream dependency is currently unavailable. The request was not processed; retry after the cooldown window.
