Rate Limits & Credits
What actually throttles MCP usage, and what each tool call costs
43 advertising platforms, the only Agentic DSP
Synter separates read-only analytics from live ad spend mutations so AI coding agents can connect, inspect accounts, and build cross-channel reports:
- Reporting & Diagnostics: All own-account read, reporting, budget pacing, anomaly diagnostic, and preflight audit tools across all 43 canonical ad platforms (Google Ads, Meta, LinkedIn, Reddit, X, TikTok, Microsoft Ads, Amazon Ads, Amazon DSP, The Trade Desk, StackAdapt, and 32 others) cost $0.00 (0 credits). Zero ad spend markup (0% fee). No credit card is required.
- SOLO Plan ($20.00 / month — Live Write Execution): Unlocks live campaign creation, budget adjustments, bid updates, pause/enable mutations, and approval gates across all 43 ad platforms (where 1 credit = $0.025 in platform usage value).

| Tool Category | Representative Tools | Credit Cost | USD Equivalent |
|---|---|---|---|
| Discovery & Account Setup | search_tools, describe_tool, check_setup, list_ad_accounts, get_credit_balance | 0 credits | $0.00 (Free) |

| Dry-Run Write Previews | create_campaign(dry_run: true), update_campaign_budget(dry_run: true), pause_campaign(dry_run: true) | 0 credits | $0.00 (Free) |
| Live Campaign Mutations (SOLO $20/mo+) | update_campaign_budget, pause_campaign, enable_campaign, execute_campaign_plan | 2–40 credits | $0.05–$1.00 |
| Campaign Creation — MCP / SDK / CLI / API (1x, Bring Your Own LLM) | create_campaign, google_ads_create_search_campaign, meta_ads_create_campaign, linkedin_ads_create_campaign | 200 credits | $5.00 |

Each tool's exact credit cost is listed on the Tool Reference page and returned by describe_tool. Credits are only deducted when a write or generation tool succeeds; failed or dry-run calls are never billed.
Request rate limiting
On top of credits, a rate limiter caps automated bursts at 60 requests per minute per user (shared across API keys for that user) to catch runaway agent loops. If you exceed 60 requests/minute, the server returns a structured JSON response:
{
"success": false,
"error": "RATE_LIMIT_EXCEEDED",
"message": "Rate limit exceeded (60 requests/minute). Please slow down.",
"retry_after_seconds": 60
}Inspect retry_after_seconds in the JSON response body and batch multi-campaign reads using list_campaigns or get_cross_channel_summary rather than polling one campaign at a time.
Daily spend caps & budget ceilings
Workspaces enforce both a daily credit-spend ceiling and configurable ad-platform daily budget ceilings (via the server-side safety gate and set_campaign_guardrail) so an autonomous agent loop cannot spend unbounded platform budget or credits in a single day.
