What You'll Need Before Starting
Before you begin the connection process, make sure you have these requirements covered:

- An active Dataslayer account
You'll need your Dataslayer login credentials ready, as you'll authenticate during the setup process. Make sure you have at least one data source connected in your Dataslayer account.
Once you have these ready, you're all set to connect!

Best Practices for Mistral AI MCP
To get the most accurate and useful results while MCP is in beta, structure your prompts clearly:
Be specific about what you want:
- Mention which metrics and dimensions you need
- Include date ranges and any filters
- Specify the data source if you have multiple accounts connected
Example of a well-structured prompt:
"Using Dataslayer, retrieve my LinkedIn Ads data for account 'Account Name'for October 2025. Show me spend, impressions, CTR, and conversions
grouped by campaign name, sorted by spend from highest to lowest."
Instead of a vague prompt:
"Show me my LinkedIn data"The more explicit you are, the better Le Chat can understand exactly which data to retrieve and how to format it.
Troubleshooting Common Issues
Experiencing difficulties? Here are solutions to frequent problems:
- Can't locate the Connectors menu: Verify you're accessing Mistral through the web interface at chat.mistral.ai. Custom connectors can only be configured via the browser, not through mobile apps initially.
- Integration fails: Confirm you've copied the MCP server URL precisely as provided, without additional spaces or typos.
- Login doesn't complete: Check that your Dataslayer credentials are accurate. If needed, reset your password through Dataslayer's platform before attempting authentication again.
- Connector appears inactive: Disconnect and reconnect the integration. A fresh authentication often resolves temporary connectivity issues.
- Queries return no data: Ensure the connector is enabled in your current chat session using the tools icon at the bottom of the conversation.
What Happens Next?
With Dataslayer MCP successfully integrated into Mistral AI, you gain conversational access to your complete marketing data directly through Le Chat. Ask questions, build reports, examine campaign performance, and uncover insights through natural language.

Once integrated, Mistral AI can:
- Access any data source linked to your Dataslayer account
- Deliver detailed analysis with trend interpretations and pattern recognition
- Build comprehensive reports and summaries on demand
- Handle follow-up questions for deeper multi-layered analysis

Authentication and Security
Mistral AI connects to Dataslayer via a secure, encrypted connection using the Model Context Protocol. Your data credentials never pass through Mistral's systems directly—all queries are processed within Dataslayer's protected infrastructure.
Mistral's security advantages:
