The Carbon Arc Connector lets eligible users connect Perplexity to Carbon Arc data, so they can ask natural-language questions about authorized Carbon Arc datasets.
To use this connector, you need an active Carbon Arc account and subscription. You also need a Perplexity Pro account to use the Carbon Arc MCP connector with Perplexity.
Carbon Arc also maintains its own Perplexity setup guide and MCP FAQs:
Use the steps below for the Perplexity connector flow. You do not need to configure a manual server address.
A Perplexity Pro account with access to Connectors.
An active Carbon Arc account and subscription.
Your Carbon Arc account credentials.
Carbon Arc offers Professional, Business, and Enterprise plans. Professional and Business plans are available through self-serve signup on Carbon Arc's Pricing page. Enterprise plans require custom commercial approval and provisioning through Carbon Arc's Sales team.
For eligible Professional and Business signups, Carbon Arc has provided the promo code PERPLEXITY30 for one month of free access.
