Connect Secondhand MCP to Perplexity

One link, a short form, and Perplexity can search real secondhand listings.

Nothing to install. You add Secondhand MCP once from a desktop browser as a custom connector, and after that it is available in your Perplexity searches. Custom connectors are a Perplexity Pro or Max feature. Secondhand MCP itself has a free tier with no credit card.

Setup steps

Takes about two minutes, once

  1. Open the Connectors page in Perplexity

    Open in Perplexity

    Use a desktop browser where you are signed in to Perplexity. If the button does not work: click your profile in the lower left, then All settings → Connectors.

  2. Add a custom connector

    Click + Custom connector in the top right, choose Remote, and fill in the form:

    NameSecondhand
    MCP Server URLhttps://secondhandmcp.com/mcp
    AuthenticationOAuthChoose OAuth. Leave Transport as it is.
    Add
    Tick the box that says you understand the risks of custom connectors, then click Add.

  3. Sign in and allow

    The new Secondhand card appears in your Connectors list. Click it to start sign-in. Use your email (we send a one-click link) or Google, then click Allow. That creates your free account, with 10 searches a month and no card needed.

  4. Try it

    Ask Perplexity for something. Copy this to start: Find a used road bike under $400 near Austin, TX

    If it answers without searching, make sure the Secondhand connector is switched on for that search.

Frequently asked questions

Do I need a paid Perplexity plan?

Yes. Custom connectors are available on Perplexity Pro and Max. Secondhand MCP itself has a free tier with 10 searches a month and no credit card.

Perplexity did not search, it just answered from the web

Open the connector card in Account settings → Connectors and make sure Secondhand is enabled, then ask again.

The sign-in email never arrived

Check your spam folder, or go back and choose Google instead. That one is instant.

Is it safe?

It can only search and read listings. It never posts, messages sellers, or buys anything. You sign in with your own email or Google, and you can remove the connector from Perplexity at any time.
