MCP Purchase Requisition in Claude.ai and Claude Desktop connectors

Purchase requisitions you build once and run per order, with a signed record of each run. You hold a requisition as a named, versioned list of steps, optionally grouped into sections, each required or optional, and run it against an order as many times as you like. A run copies its requisition's steps when it starts and records the version, so editing the requisition afterwards never changes a run already under way. run_check marks steps pass, fail or na with who and when (na counts as answered, never as passed; a required step failed blocks sign-off), run_report gives the whole run with failures in full, and run_sign_off puts a name and a date on it and freezes it. RUN-YYYY-NNNN ids are sequential and never reissued.

The requisitions and their runs live in the hosted store behind the token, so the three free requisitions and their REQ-YYYY-NNNN numbers follow the key rather than the machine. There is no network call inside the server on any route, so the snapshot rule is identical here and on a laptop, and run_report's .txt output comes back in the answer itself, because a hosted call has nowhere local to write it.

What you get

You sayTool
Make a pre-delivery vehicle check requisition: tyres, lights, load secured.purchase-requisition_create then purchase-requisition_item_add
Start a run of it for van BX21 KLM against PO-0031.run_start
The weight step failed at 3620 against a plated 3500. Can it be signed off?run_check then run_sign_off

The unit suite is 15 tests, 15 passing, 0 failing (node --test, node v22), covering the snapshot rule, the na-is-not-pass rule and the sign-off freeze; adversarial, concurrency, paths and contract suites sit alongside it.

Connect it, no install

https://mcp.zovo.one/mcp/connect mints an anonymous token and prints a URL per server, including this one, shaped like https://mcp.zovo.one/mcp/purchase-requisition/t/<token>. That URL works with no headers: the token is in the path, not in an Authorization field this form does not have.

  1. Open https://mcp.zovo.one/mcp/connect and copy the URL printed for MCP Purchase Requisition.
  2. There is no config file here: the Add custom connector form asks for a name and a Remote MCP server URL, with an Advanced settings section for an optional OAuth Client ID and Client Secret.
  3. Paste the URL as the Remote MCP server URL. Leave the optional OAuth Client ID and Client Secret blank; this endpoint does not use them.
  4. Click Connect, then turn the connector on for a conversation from the + button, Connectors.

Idle anonymous tokens are swept after 30 days. Since this route has no filesystem, a file MCP Purchase Requisition generates comes back as a download link that expires after one hour. A Pro key can replace the token in the same URL and removes the free-tier limits.

Claude.ai and Claude Desktop connectors notes worth knowing first

On an individual Pro or Max plan you add the connector yourself from Customize, Connectors. On Team and Enterprise it is the other way round: only an Owner or Primary Owner can add a custom connector, at Organization settings, Connectors, and members then connect to what the Owner added rather than pasting their own URL.

Free: Three requisitions, and unlimited runs of them on every tier, because capping the running of a requisition would cap the only thing a requisition is for. Deleting a requisition frees its slot and every run stays readable. Pro is $19 once, verified offline, and binds to the token after checkout.

Questions

Does this need OAuth?

No. Add custom connector offers an Advanced settings section with an OAuth Client ID and Client Secret, but the connect-by-URL route does not use it. Leave both blank: the token in the URL path is what authenticates.

I am on a Team or Enterprise plan and cannot add a connector.

That is documented, not a bug: on Team and Enterprise, only an Owner or Primary Owner can add a custom connector, at Organization settings, Connectors, Add, Custom, Web. After that, members connect to the URL the Owner added from Customize, Connectors.

Can I use my Pro key instead of the free anonymous token?

Yes. The token segment of the URL from /mcp/connect can be replaced with a Pro key, which removes the free-tier limits on MCP Purchase Requisition for that connector.

Why did a generated file come back as a link instead of opening?

The connector runs server-side with no filesystem of its own, so any file MCP Purchase Requisition produces is handed back as a download link that expires after one hour, rather than a path on disk.
