Yes, MCP usage has two types of limits: Dataslayer's 50 API calls per day and your AI provider's message limits. Understanding both helps you plan your usage effectively.
When using Dataslayer MCP, you're subject to two separate limits that work together: Dataslayer's API call limits and your AI provider's message restrictions.
Dataslayer API Call Limits
What is an API call? An API call happens each time Dataslayer MCP queries your connected data sources to retrieve information. When you ask your AI provider a question that requires actual marketing data, that's one API call.
During your 15-day free trial: 50 API calls per day
- Start using MCP immediately with your trial
- No credit card required
- Full access to test with your actual data
With an active Dataslayer subscription: 50 API calls per day
- Applies to any paid Dataslayer plan
- Included as added value with your subscription
- No extra cost beyond your existing plan
Without an active subscription:
- MCP is not accessible after trial ends
- Subscribe to any Dataslayer plan to regain access
Daily limit details:
- Resets daily at midnight UTC
- Shared across all connected AI providers
What counts as an API call: Each time the AI requests data from Dataslayer, it consumes one API call:
- Querying metrics and dimensions
- Retrieving campaign data
- Fetching performance reports
- Any request that pulls data from your connected sources (Google Ads, Meta Ads, GA4, etc.)
What doesn't count as an API call:
- Questions that don't require data retrieval
- Requests for metric explanations ("What does CTR mean?")
- Help building query structures ("What metrics should I use to analyze profitability?")
- General conversation with the AI
For most users, 50 calls per day is more than enough to ask dozens of questions, run multiple analyses, and explore marketing performance thoroughly.
AI Provider Message Limits
Each AI provider has its own restrictions:
Claude (Anthropic)
- Free tier: MCP not supported
- Claude Pro ($20/month): ~45 messages every 5 hours (5-hour rolling window)
- Claude Team: Higher limits, priority access
For complete details, see Claude's official rate limits documentation and Claude pricing plans.
ChatGPT (OpenAI)
- Free tier: MCP not supported
- ChatGPT Plus ($20/month): 80-160 messages every 3 hours (3-hour rolling window), requires Developer mode (beta), web only
- ChatGPT Pro ($200/month): Unrestricted access (subject to fair use)
For complete details, see OpenAI's usage limits documentation and ChatGPT pricing plans.
Mistral AI
- Free tier: ~20-25 messages per day, MCP supported (only provider with free MCP access)
- Pro ($14.99/month): ~120-150 messages per day (6x free tier)
- Team/Enterprise: Custom limits
For complete details, see Mistral AI's rate limits documentation and Mistral AI pricing plans.
How the Limits Work Together
Both limits apply simultaneously. Whichever limit you hit first determines your capacity.
Example: Using Claude Pro with 216 daily messages and Dataslayer's 50 API calls:
- If every message requires data: You'll hit the 50-call Dataslayer limit first
- If you mix data queries with general questions: You might use 100 Claude messages but only 30 API calls
Best Practices
- Batch your queries: Combine multiple questions into comprehensive requests.
- Use AI for planning: Ask the AI to structure queries before executing them, this uses AI messages but not Dataslayer API calls.
- Leverage explanations: Ask about metrics and dimensions without pulling data, these don't count as API calls.
- Choose strategically:
- Testing on a budget: Mistral AI Free (only provider with free MCP)
- High message volume: Claude Pro or ChatGPT Plus
- No limits: ChatGPT Pro
What Happens When You Hit a Limit?
Dataslayer API limit:
- Further data queries fail until midnight UTC reset
- AI can still help with non-data tasks
AI provider limit:
- Claude: Cannot use the model until 5-hour reset
- ChatGPT: Auto-switches to mini version until 3-hour reset
- Mistral AI: Cannot send messages until daily reset
