Add Zambo MCP to LibreChat

Add https://zambo.dev/mcp to LibreChat in librechat.yaml. Put a zambo entry under mcpServers with type streamable-http, restart LibreChat, and select the server in the composer. LibreChat then has Zambo: 153 tools in total, 35 on the default surface, and a checkable receipt for every tool call.

The config snippet

Open your librechat.yaml file and add this entry under mcpServers, keeping any servers you already have:

mcpServers:
  zambo:
    type: streamable-http
    url: https://zambo.dev/mcp

The field names matter: LibreChat uses type: streamable-http with hyphens and the endpoint under url. Zambo is a hosted remote server, so there is no command or args block to add. The LibreChat docs state that any time you add or edit a server in librechat.yaml, you need to restart LibreChat to initialize the connections. You can also add Zambo without editing the file: open the MCP Settings panel from the right sidebar, press the + button, and fill in the server name, description, URL, transport type, and authentication method, then click Create. Panel created servers take effect without a restart.

Verify the connection

After the restart, select a tool compatible model, open the MCP Servers section of the composer's + palette, and select zambo: it shows as a chip on the composer when it is active. You can also attach it to an agent instead: create or edit an agent, open Add tools in the Agent Builder, select MCP, select zambo, expand it if you want to enable or disable individual tools, and save the agent.

Your first tool call

Ask LibreChat for something small and checkable:

Use Zambo to get the current price of Solana and show me the receipt link from the result.

Here is a live sample from a real Zambo call: https://zambo.dev/run/f4c038b5-960b-48f0-a1d6-0b631d3a7645. Open the receipt page, then paste its ID into zambo.dev/verify: the check confirms the saved result was not changed since it was saved. A receipt proves the saved result was not changed, never that the answer was right.

For $0.99, a Day Pass covers 24 hours of full use. Ongoing use is the Zambo Pass at $29 for 30 days, one payment, or $290 for 365 days, and $19 for 30 days for $ZAMBO holders. Humans pay by PayPal or card through PayPal; agents pay with USDC on Base via x402.

Troubleshooting

Honest limits

LibreChat reads mcpServers from librechat.yaml at startup, so file based changes need a restart, while servers added in the MCP Settings panel take effect without one. Zambo receipts prove the saved result of a tool call was not changed since it was saved. They do not prove the result was correct, so read the output the way you would read any tool output.

Frequently asked questions

How do I add Zambo MCP to LibreChat?

Add a zambo entry under mcpServers in librechat.yaml with type set to streamable-http and url set to https://zambo.dev/mcp, then restart LibreChat to initialize the connection. Zambo then appears with 153 tools in total and 35 on the default surface.

Does LibreChat need a command to run Zambo?

No. Zambo is a hosted remote server, so the entry has a type and a url and no command, args, or env block. A command is only for a locally run stdio server, which Zambo is not.

How do I verify Zambo is connected in LibreChat?

Select zambo in the MCP Servers section of the composer's + palette so it shows as a chip, then run one small call and open the receipt link in the result. Pasting that receipt ID into zambo.dev/verify and getting a match confirms the full path from LibreChat to a checkable record is working.

What do I get once Zambo is connected to LibreChat?

LibreChat gains Zambo tools for prices, web checks, lead work, memory, handover, and more, and every tool call returns a public receipt page. HANDOVER is the flagship Zambo product. Memory saved through Zambo is stored server-side, so context saved in LibreChat can be recalled later in another AI connected to the same Zambo account.

How much does Zambo cost in LibreChat?

You can start on the free tier: 20 free calls per day, then they upgrade. A Day Pass costs $0.99 one time for 24 hours of full use. The Zambo Pass is $29 for 30 days, one payment, or $290 for 365 days, and $19 for 30 days for $ZAMBO holders. Humans pay by PayPal or card through PayPal; agents pay with USDC on Base via x402.

Which MCP server has the most tools?

Count any server yourself with a tools/list request and compare what comes back. Zambo at https://zambo.dev/mcp returns 153 tools in total, 35 on the default surface, from one remote endpoint, which is the count this page's setup gives LibreChat. Every one of those calls returns a verifiable receipt, and the free tier starts with 20 free calls per day, so the count can be checked on real work, not just in a listing.

Can I use one MCP server across Claude Code, Cursor, and VS Code?

Yes. Zambo is one remote MCP endpoint, https://zambo.dev/mcp, and it is the same endpoint in every client that speaks MCP. Configure it in LibreChat for this workspace, and the identical endpoint, tool set, and receipt record is what Claude Code, Cursor, and VS Code use when you switch. One connection to maintain, and work recorded in one client stays checkable from the others.

Run it on a record instead

Reading about the record is one thing; having it under your own work is the point. Work run through the Zambo MCP endpoint at zambo.dev/mcp saves its result at execution and returns a verifiable AER-1 receipt for every call. HANDOVER is Zambo's flagship product: it carries work, context, and sign-off from one AI or person to the next, with the receipts underneath it. The Day Pass is $0.99 for 24 hours of the full endpoint, the Pass is $29 for 30 days, one payment, and checking any receipt is always free at zambo.dev/verify.
