Which one, for what

Airwallex Spend and Issuing B

  • Agent ergonomics, 69 against 55
  • Security & auth, 84 against 71

Pleo API + MCP B

Good for An agent that completes, codes, reviews and queues expenses for a Pleo customer on the Optimise plan, or for a bookkeeping integration that exports accounting entries and syncs tags, tax codes, accounts and vendors.

Ahead on

Watch for

The pricing page lists MCP on the Optimise plan only (£18 per user per month, three users minimum, sold through a demo)

Verdicts

Airwallex Spend and Issuing

Scoped API keys split read from write per resource, tokens last 30 minutes, and the sandbox opens at once with no contract. No OpenAPI spec was found, every Spend endpoint read is marked beta, the pricing page lists direct Spend API integration under the custom-priced Accelerate plan, and no SLA was found.

Pleo API + MCP

The hosted MCP server acts with the connecting user's own Pleo permissions, is off until an admin enables it per entity, and can't move money, change cards or alter limits. It is listed only on the Optimise plan, its tool definitions aren't published, API keys need enabling by Pleo support, and no official SDK or SLA was found.

Before you call either

Airwallex Spend and Issuing

  1. Exchange x-client-id and x-api-key at POST /api/v1/authentication/login once, then reuse the bearer token for 30 minutes. The login endpoint allows 100 requests a minute per key
  2. Create Spend keys with organisation-level permissions. With a key linked to several accounts, send x-login-as at login or the token carries no account permissions
  3. Send a fresh UUID as request_id on every create call and reuse the same value when retrying after a timeout
  4. Expect two pagination styles. Spend and card transaction events use the page bookmark with page_after and page_before. Cards and legacy transactions use page_num and has_more
  5. Card and expense lists default to the last 30 days. Pass both created-at bounds to read further back, and fetch a card singly to see its authorization_controls

Pleo API + MCP

  1. Ask a company admin to enable Pleo MCP access under Settings, General, Pleo AI for each entity before connecting. It is off by default
  2. Name the entity in every request when working outside the default one. Each MCP request targets one entity and the choice doesn't persist
  3. Set the AI client to require approval for Pleo write tools. Pleo leaves confirmation to the client and doesn't enforce it server-side
  4. Send API keys as the Basic auth username with an empty password to external.pleo.io. Legacy tokens for openapi.pleo.io don't work there
  5. Budget every endpoint against one bucket of 600 requests a minute per credential, and on 429 wait for Retry-After or back off from one second
  6. Swap mcp.staging.pleo.io for mcp.pleo.io in the Claude Code command when moving from staging to production. Each needs its own OAuth sign-in
