Get Started
Using the Public Hosted MCP Server
Connect your Public.com brokerage account to AI agents through the Public-hosted MCP server. Unlike the self-hosted setup, you don't need to install anything locally. Just point your MCP-compatible client at the hosted endpoint and authenticate. This tutorial walks through setting up the hosted MCP in Perplexity Computer.
Before You Get Started
- →You will need a Public.com brokerage account. Create one at public.com/signup.
- →An MCP-compatible client. In this tutorial we'll be using Perplexity Computer.
- →An API key. Generate one from the API settings page of your Public account.
Perplexity Computer
Paid plan required
Adding a custom connector to your Perplexity account requires a paid Perplexity plan. Make sure your account is on a paid tier before continuing.
- Navigate to perplexity.ai/computer/connectors.
- Once on the connectors page, click the + Custom connector button in the top right.
- In the Add custom connector form, fill out the fields as follows:
- Name: public.com
- MCP server URL:
https://mcp.public.com/mcp - In the Advanced section, under Authentication, select API Key from the dropdown and paste your API key into the field.
- For the Transport dropdown, select Streamable HTTP.
- Accept the terms and click Add.
- In the Available connectors section, you should now see the public.com connector listed as an option. Click on it, then click Add connector.
That's it. You're done. Start a new task in Perplexity Computer and you can begin prompting to interact with your Public brokerage account.
