## Summaries

### 293. Pleo API + MCP, B (62.9)

Spend management platform from Pleo Technologies A/S in Copenhagen, covering company cards, expenses, reimbursements, invoices and accounting exports. Outside agents reach it through a hosted MCP server for expense work and a REST API built for accounting integrations. 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.

### 306. Spendesk API + MCP, B (62.3)

Spend management platform from Spendesk SAS in Paris, covering company cards, expense claims, supplier invoices, purchase orders and accounting exports. Outside agents reach it through a REST API with scoped keys or OAuth, and a hosted MCP server. Scoped credentials, MCP write permissions that are off by default, an action log and published guidance on prompt injection suit delegated finance work. Access needs a paying customer and a request to Spendesk, most write endpoints are experimental, no official SDK was found, and the status page lists three critical incidents between 2 and 29 September 2026.

Expensify is an expense management service with receipt scanning, expense reports, approvals, reimbursement and company cards. Its Integration Server API exports report and card data and creates expenses, reports and workspace settings. A hosted MCP server gives read-only search. One endpoint exports reports through caller-written templates and creates expenses, reports, rules and workspace settings, with limits of 5 requests per 10 seconds published and a status page that tracks the API separately. There is no OpenAPI spec, changelog, SDK, pagination or idempotency key, and one credential pair carries the whole account's rights.

## How we test this category

One test company with a fixed set of card transactions in each listing's sandbox. The same tasks run through its API (list transactions, attach a receipt, code an expense, create a spending limit, read a bill). We check scopes, approval points and the audit record. In this run listings are graded from public evidence against the published checklist. This test hasn't run yet, so Task success is pending and the grades here come from the categories assessed from public evidence.
