How to connect Perplexity to Tesselith

Add Tesselith to Perplexity as a custom remote connector, research a topic and schedule the posts in one place. Perplexity talks to Tesselith’s MCP server, so it can draft, queue and schedule posts on every channel you’ve connected. Keep a human in the loop: publishing now and deleting always ask for your confirmation.

Why is Perplexity not working with Tesselith?

Connection failsSet Transport to Streamable HTTP under Advanced.
Connector added but unusedEnable it for the thread you're in.
403: your plan doesn't include API accessMCP is included on Pro, Team and Agency. New workspaces get a 14-day Pro trial; upgrade under Settings → Billing.
