name: ADSMCP Support
description: >-
REST endpoints for every ADSMCP tool. Same surface as the MCP server, over
plain HTTP for consumers that can't speak SSE (n8n, Zapier, Make, curl, any
language's HTTP client).
## Envelope
Every request wraps tool-specific input in an `arguments` object:
```json
{ "arguments": { <tool-specific fields> } }
```
Every response wraps the result in either a success envelope (`success:
true`, `data: {...}`) or an error envelope (`success: false`, `error:
"..."`, `is_error: true`).
## Authentication
Pass your API key as `Authorization: Bearer sk_live_...` on every request.
Generate keys at https://adsmcp.si/dashboard/api-tokens.
## Quota & billing
Every successful billable call decrements your monthly tool-call allowance.
The current counter is attached to every 200 response under `data.quota`:
```json
"quota": { "used": 42, "limit": 150, "tier": "plus", "period_end":
"2026-05-01" }
```
When the limit is hit, the API returns HTTP 402 with a full `quota` block
including `upgrade_url`. Read-only diagnostic tools (`get_usage_status`,
`list_connected_accounts`, `get_connections_status`) are exempt and never
consume quota.
## Idempotency
Write operations accept an `Idempotency-Key: <uuid>` header. A repeated call
with the same key returns the cached result rather than executing twice.
**Strongly recommended for n8n, Zapier, and any retry-prone client** — it
prevents duplicate campaigns when networks misbehave. Generate a fresh UUID
per logical operation (not per retry).
## Multi-account users
Customers with multiple connected accounts on the same platform (e.g. an
agency with 10 Meta ad accounts) must specify which account to use via
`ad_account_id`, `customer_id`, `advertiser_id`, or `account_id` depending
on the platform. Omitting it returns HTTP 400 with a list of valid account
IDs. See `list_connected_accounts` to discover available IDs.
## HTTP status codes
- `200` — success (parse `data`)
- `400` — tool-level error (surface `error` to users)
- `401` — bad/missing API key
- `402` — ADSMCP quota exhausted
- `404` — unknown tool name
- `429` — upstream ad platform rate-limited us (Meta/Google/etc.) — retry
with backoff
- `500` — server error, report to support
## Streaming
This endpoint is plain request-response JSON. There is **no SSE, no chunked
streaming**. Safe to use from n8n Cloud's HTTP Request node, Zapier
Webhooks, Make HTTP module, curl, and every mainstream HTTP library.

summary: Detect Meta Creative Fatigue
description: >-
User asks about creative fatigue, ad refresh timing, frequency
management, declining CTR, when to replace ads, or audience exhaustion
on Meta/Facebook/Instagram.
This tool analyzes all Meta Ads creatives for fatigue indicators using
frequency-CTR correlation analysis and provides a fatigue score (0-100)
for each ad.
Returns:
- Fatigue score (0-100) for each ad based on weighted factors
- Severely fatigued ads (score ≥80) - immediate action required
- At-risk ads (score 50-79) - plan refresh within 7-14 days
- Healthy ads count
- Daily spend being wasted on fatigued creatives
- Projected monthly waste
- Refresh schedule recommendations
- Contributing factors for each fatigued ad
When to use this tool:
- "Are any of my Meta/Facebook/Instagram ads fatigued?"
- "When should I refresh my creatives?"
- "Why is my CTR declining?"
- "Which ads have high frequency?"
- "How much am I wasting on fatigued ads?"
- "What's my ad refresh schedule?"
- "Are my retargeting ads showing too often?"
Parameters:
- lookback_days: 7, 14, 30 (default), 60, or 90 days
- start_date: Optional start date (YYYY-MM-DD). Overrides lookback_days
when used with end_date.
- end_date: Optional end date (YYYY-MM-DD). Overrides lookback_days when
used with start_date.
⚠️ DATE CLARIFICATION: If the user's date request is vague or ambiguous
(e.g., "March to June" without a year, "last quarter", "recently", "a
few months ago"), ask the user to specify exact dates before calling
this tool. Do not assume or guess dates.
- frequency_threshold_cold: 2.0-8.0 (default: 4.0) - threshold for cold
traffic audiences
- frequency_threshold_retargeting: 4.0-10.0 (default: 7.0) - threshold
for retargeting audiences
- ctr_decline_threshold: 0.10-0.50 (default: 0.20 = 20%) - CTR decline
to flag as fatigued
- ad_account_id: Required for multi-account users. Get from
list_connected_accounts
Execution time: 2-5 seconds (cached database query with analysis)
Data source: meta_ad_creative_metrics table (ad-level daily metrics with
frequency, CTR, video completion)
Fatigue Score Calculation:
The fatigue score (0-100) is calculated using weighted factors:
- Frequency (40%): impressions/reach ratio vs threshold
- CTR Decline (35%): % drop in CTR vs previous period
- Days Running (25%): creative age vs optimal refresh timing
Severity Levels:
- 🔴 Score ≥80: Severely fatigued - PAUSE immediately and replace
- 🟡 Score 50-79: At risk - prepare replacement within 7-14 days
- ✅ Score `<`50: Healthy - continue monitoring
Best practices:
- Cold traffic: Refresh creatives when frequency reaches 3-4x
- Retargeting: Can tolerate higher frequency (up to 6-7x)
- Create 3-5 variations per ad set for automatic rotation
- Monitor weekly for frequency and CTR trends
