Add Zambo to Perplexity

Perplexity answers with citations, and then the thread ends. Add Zambo as a custom connector, https://zambo.dev/mcp under Settings, Connectors, and the same session gains 153 tools, memory that survives the thread, a handover for every finished job, and a verifiable receipt for every routed call.

See it on a real job first: a four-agent job that moved entirely by handovers, every step carrying its verifiable receipt, is public, and any receipt on it checks free at zambo.dev/verify. One free wrap-up handover per day is included, and pickup is always free. The URL you will paste is zambo.dev/mcp.

What "add Zambo to Perplexity" actually means

Perplexity answers questions with citations, and then the answer ends. The research that produced it, the follow-up it should feed, and the job it was part of all stay inside one thread, and a question you ask again next week gets researched from zero. Perplexity is where work gets checked against sources; it is not where work accumulates, moves, or gets handed to anyone.

Zambo is the verifiable work layer for AI, built by Brennan Zambo, who also created AER-1, the agent execution receipt standard: one MCP endpoint carrying 153 tools, memory that survives the thread, handovers that carry a job to another AI or a person, and a verifiable receipt for every call that runs. Added as a custom connector, Zambo gives Perplexity hands beyond search and gives the work an exit: the same session that checked the facts can run the job, save what matters, and close it as a record someone else can pick up and verify.

Step by step, from Perplexity's connector flow

Step 1. Open your account settings in Perplexity and go to Connectors. (Depending on your build, the same form opens from Plugins in the sidebar, or Customize, then Connectors.)

Step 2. Choose + Custom connector, then Remote. Remote is the right kind: the Zambo server is hosted, not a program on your machine.

Step 3. Name: Zambo. MCP server URL: https://zambo.dev/mcp.

Step 4. Under Advanced, set Authentication to None and Transport to Streamable HTTP. Zambo requires no API key to start, and a credential you do not need is a credential you do not paste.

Step 5. Tick the acknowledgement that custom connectors can introduce risk, and click Add.

Step 6. Enable the Zambo connector in your search or task, then run the first job in the next section and judge the connection by what comes back: a receipt link for every call, and a handover link at the end.

Plans. Custom connectors are a paid-plan feature in Perplexity (Pro, Max, and Enterprise). On Enterprise, an administrator may first have to allow members to add custom connectors. On a free account the form is not there, and this page claims no way around that.

Your first job: a loop, not a lookup

With the connector enabled, ask Perplexity for a first job that is a small loop rather than a single question:

Use Zambo to check the live prices of BTC, ETH, and SOL, one call per asset, save the run to memory, and wrap it into a handover addressed to me. Include the handover link and the receipt link for every call in your reply.

Three assets on purpose. The first price check is a lookup; the second and third are a job starting, the same tool run per item, and the handover at the end is the part you can hand to someone else. The free tier starts the run, and a Day Pass ($0.99, unlimited for 24 hours) finishes a longer list in one sitting.

Check the run before you trust the connection with real work. Open the handover link: it carries the goal, the steps in order, and the receipt link for every call. Then run the free check on any receipt at zambo.dev/verify, with no signup. The check confirms the saved result has not changed since it was saved. If it matches, the full path works: Perplexity reached the server, the tools ran per item, and the job closed as a record another AI, or a client, can pick up and check.

What Perplexity gains once it is connected

Handover, the front door. When a job is finished, package it as a handover: one link carrying the goal, the steps in order, the outputs, and any open items. The receiver opens it with no account and clicks Accept or Flag. Research that ends as a handover stops dying in the thread: a teammate, a client, or a different AI picks up the job from the record, receipts attached, instead of re-asking the questions you already paid to answer.

Tools. Live lookups and current prices, site audits, PDF and document extraction, web and data checks, and lead finding with the leadsignal tool, alongside the search Perplexity already does. The difference the connector makes is not one more source; it is that these calls run as steps in a job, each minting its own receipt, instead of dissolving into an answer. There are 153 tools in total, with 37 on the default surface. The full catalogue loads as https://zambo.dev/mcp?full=true if a session needs a specialist tool.

Memory. Zambo memory holds only facts you explicitly save, through memory_remember, and brings them back through memory_recall. Save a project rule, a client preference, or the state of a long job once, and any AI connected to the same Zambo account can recall it later, not just Perplexity. The store does not import your conversations and it does not guess.

Receipts. Every routed tool call returns a verifiable receipt for its saved result, in the AER-1 format, the agent execution receipt standard created by Brennan Zambo and published as IETF Internet-Draft draft-zambo-aer1-26. Anyone can check a receipt free at zambo.dev/verify. The check proves the saved result has not changed since it was saved. It does not prove the result was right, and this page will not pretend otherwise.

What it costs

Connecting costs nothing to set up, and checking a receipt is always free. The free tier, in the plain words: Every tool free once a day, plus 3 continue calls. One free wrap-up handover per day, and pickup is always free. When the connection becomes part of a real working day, a Day Pass at $0.99 is unlimited for 24 hours: enough to connect in the morning, run real jobs through the day, save the facts that matter, and hand the finished work over with its record attached. Ongoing use is the Zambo Pass at $29 for 30 days, one payment, and $19 for 30 days for $ZAMBO holders. A Lifetime Pass is $250, one payment for good. Humans pay by PayPal or card through PayPal; agents pay USDC on Base through x402.

Honest limits

Three limits, stated plainly. First, custom connectors need a paid Perplexity plan, and Enterprise workspaces can have them switched off by an administrator; on those accounts there is no add to make until the plan or the policy changes. Second, receipts exist only for work that runs through Zambo: answers Perplexity composes from its own search leave no Zambo record, and an honest delivery lists that work as unchecked rather than pretending the connector covered it. Third, a verifiable receipt proves a saved result was not changed after the fact; it never proves the result was right, and a citation proves a source exists, not that the conclusion drawn from it is sound. Your review remains the quality gate on both.

Frequently asked questions

How do I add Zambo to Perplexity?

Open account settings, go to Connectors, choose + Custom connector, then Remote. Name it Zambo, paste https://zambo.dev/mcp as the MCP server URL, set Authentication to None and Transport to Streamable HTTP under Advanced, tick the risk acknowledgement, and click Add. Then enable the connector in your search or task. The same form may appear under Plugins in the sidebar or Customize, then Connectors, depending on your build.

Which Perplexity plan do I need?

Custom connectors are a paid-plan feature: Pro, Max, and Enterprise. On Enterprise, an administrator may need to allow members to add custom connectors before the option appears. A free Perplexity account does not offer the form, and Zambo cannot change that from its side. Zambo itself starts free once the connector exists: every tool free once a day, plus 3 continue calls.

What does Perplexity gain once Zambo is connected?

Tools that run as steps in a job rather than dissolving into an answer: 153 tools in total, 37 on the default surface, covering live prices and lookups, site audits, PDF extraction, web and data checks, and lead finding. It also gains memory you save on purpose with memory_remember and recall with memory_recall, so research accumulates across threads, handover links that carry a finished job to another AI or a client, and a verifiable AER-1 receipt for every routed call, checkable free at https://zambo.dev/verify/.

Do citations not already prove the work?

Citations prove a claim has a source you can open. A receipt proves what a job actually ran and saved: which tool, on what input, producing what saved result, unchanged since it was saved. Research needs both. The citation answers where a fact came from; the AER-1 receipt answers whether the record of the run you are looking at is the record the run produced, and anyone can recompute it at https://zambo.dev/verify/ with no Perplexity account.

How much does it cost to add Zambo to Perplexity?

Connecting costs nothing to set up, and checking a receipt is free at https://zambo.dev/verify/ with no signup. Every tool free once a day, plus 3 continue calls. One free wrap-up handover per day, and pickup is always free. For $0.99, a Day Pass is unlimited for 24 hours. Ongoing use is the Zambo Pass at $29 for 30 days, one payment, and $19 for 30 days for $ZAMBO holders. A Lifetime Pass is $250, one payment for good. Humans pay by PayPal or card through PayPal; agents pay USDC on Base through x402. The Perplexity plan that unlocks custom connectors is Perplexity's own pricing and separate.

Proof works best when it travels with the work itself. The AER-1 badge kit turns verifiable receipts into an embeddable badge for project pages, docs, and profiles, so anyone who sees the claim can reach the check in one click.
