Stripe

How to use this skill

This skill uses Stripe's official remote MCP server at https://mcp.stripe.com. Maverick's config-level allowlist is the source of truth for which of Stripe's advertised tools are visible to the assistant.

Step 1 — Discover the live tool catalog and any server-published usage instructions. Always run this first; do not rely on tool names from memory:

mcporter --config {baseDir}/mcporter.json list maverick-stripe-mcp --schema

The output includes the server's Instructions: field, if published, and a JSON Schema for every tool's parameters. Treat this as the authoritative reference for the rest of the session.

Step 2 — Call an allowlisted read tool using the form maverick-stripe-mcp.<tool>:

mcporter --config {baseDir}/mcporter.json call maverick-stripe-mcp.<tool> <arg>=<value> ...

Add --output json for structured output and transport-error envelopes:

mcporter --config {baseDir}/mcporter.json call --output json maverick-stripe-mcp.<tool> ...

Safety

The exposed tool set is intentionally read-only. stripe_api_write, create_refund, the mixed read/write stripe_report, send_stripe_mcp_feedback, and the Treasury-preview get_balance_summary are invisible at the mcporter protocol layer. Refunds, subscriptions, invoices, payment links, customer/payment mutations, and every other write remain unavailable until Maverick has a real execution-time approval gate.

stripe_api_read is documented as GET-only, but it accepts broad Stripe API paths and may reach preview GET endpoints. mcporter filters exact tool names, not tool arguments, so do not describe this allowlist as a resource-path restriction.

Use Stripe sandbox for validation and confirm the selected Stripe environment before account-data reads. The broker does not persist sandbox/live mode, so local authorization or sync state proves neither environment. Sandbox and live MCP authorizations are separate; never infer one from the other or switch environments without the user's explicit intent.

Authentication

Ordinary single-account authorization uses Stripe's MCP-native OAuth flow: protected-resource discovery, dynamic public-client registration, Authorization Code with PKCE S256, and refresh tokens. Credentials are provisioned by scripts/setup.sh into mcporter's local vault; mcporter sends and refreshes the resource-bound bearer token for the official remote MCP.

Setup needs bash, jq, basename, and mcporter (>= v0.11.0). Run setup only after fresh authorization or credential rotation. Re-running it with stale values can overwrite a refresh token already rotated in the vault.

Dashboard revocation is user-visible and invalidates the remote grant. Maverick does not currently receive a provider-revocation callback, so its local grant can remain active/synced until a remote call fails or the user disconnects. Those local states prove only that authorization was saved and the bundle/credential projection succeeded; they are not evidence that Stripe remains authorized.

Stripe Connect connected-account operations are a separate exception. They require a restricted key plus Stripe-Account context and must never be described as MCP-native OAuth. This bundle does not implement or expose that path.
