PayPal MCP Integration

2 min read Updated May 19, 2026
Transactions and subscription data from your PayPal Business account, alongside Stripe and Square in cross-processor reporting.

PayPal still handles a meaningful share of payments for many businesses. Connecting your PayPal account to clariBI brings those transactions and subscriptions into the same place as your Stripe and Square data.

Why connect PayPal

When PayPal lives outside your main payment reporting, revenue analysis splits across spreadsheets. The clariBI MCP connection makes PayPal a first-class source.

You can compare PayPal volume to other processors, track subscription churn for PayPal-billed customers, or pull out reconciliation reports across providers.

How the connection works

clariBI talks to PayPal through its hosted MCP server at https://mcp.paypal.com/sse. Authentication uses an OAuth flow that clariBI registers itself for (no developer console setup on your side). Tokens stay encrypted server-side and never leave clariBI in clear form.

    C->>V: Open OAuth authorization
    V-->>U: Grant read access?
    U->>V: Approve
    V-->>C: Authorization code
    C->>V: Exchange code for tokens
    V-->>C: Access + refresh tokens
    C->>C: Encrypt and store credentials
    C-->>U: Connection ready

Available tools

clariBI exposes the read-only PayPal tools that the vendor's MCP server publishes at connection time. Write operations (create, update, delete, send, refund) are filtered out by a name-pattern blocklist before any tool reaches the analysis engine, so connecting PayPal cannot modify data on the vendor side.

The exact tool inventory depends on the PayPal features your account has access to. After connecting, try a few natural-language questions to see what PayPal data clariBI can pull.

Data flow during analysis

When you ask a question that maps to PayPal, the AI engine routes to the right tool, reads the result, and pairs the answer with a chart you can pin to a dashboard.
