See what an agent can do with SumUp before you ever sign up. Pick a story: recorded sessions replay real probe-harness transcripts; the live MCP handshake runs real requests from our edge, right now — including, where the server allows it, one real read-only tool call (bring your own key for auth-gated servers); sandboxed self-drive sessions are designed and gated (docs/TRY-IT.md).

Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 33 stories with headroom
What would move SumUp’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.
Agenticness — how well agents can access and operate the productDelegate tasks to a built-in AI assistant inside the product
nonemoves Built-in AIimpact 45
SumUp's evidence only shows it exposes an MCP server and Agent Toolkit so that external AI agents/coding assistants can call SumUp APIs — this is SumUp acting as a tool provider for other agents, not a built-in AI assistant embedded in the SumUp product itself that a user can delegate tasks to.
Disputes refunds — stories about disputes refunds in this arenaHave an agent monitor dispute deadlines via API or webhooks and draft evidence responses for my review
nonemoves PA Scoreimpact 30
SumUp's docs cover checkouts, refunds, webhooks for checkout status, and MCP/agent tooling, but there is no evidence of a disputes/chargebacks API, dispute deadline data, or evidence-submission endpoints that an agent could monitor or draft responses against.
Hardware fleet — stories about hardware fleet in this arenaHave an agent provision a new location end-to-end via API — creating the location and registering its readers
nonemoves PA Scoreimpact 30
Missing: location creation API, reader-to-location registration endpoint, any end-to-end provisioning example.
Automation depth — how much of the product can run unattendedDefine rules that trigger actions automatically on events
nonemoves PA Scoreimpact 30
SumUp's docs show only basic webhook notifications for checkout status changes (via return_url), not a rules engine allowing users to define custom conditions/actions across events; no evidence of any automation/rules builder.
Openness — open source, data portability, and self-hosting storiesExport all of my data in open formats and leave
nonemoves PA Scoreimpact 30
SumUp is a payments platform holding transaction/merchant data, and the evidence pack has no mention of any data export feature (open formats like CSV/JSON export of transactions, merchant data, or account closure/data portability tooling); it covers payment APIs, MCP/agent tooling, and checkout flows but nothing about exporting user data and leaving.
Accept payments — stories about accept payments in this arenaSign up, get approved, and order hardware from the dashboard so I am taking in-person payments the same week
nonemoves PA Scoreimpact 30
The evidence pack is entirely developer-API documentation (checkouts, SDKs, MCP servers, cloud API, refunds) and pricing claims; it contains no evidence about the merchant signup/approval workflow or ordering hardware from a dashboard, which is the core of this founder-onboarding story.
Agenticness — how well agents can access and operate the productSet up automations that run autonomously in the background
nonemoves Built-in AIimpact 30
SumUp is a payments API/platform with webhooks, an MCP server, and an agent toolkit for building agentic integrations, but there is no evidence of a native automation/workflow feature that runs autonomously in the background (e.g., scheduled jobs, triggers, rules engine) within SumUp itself — it only exposes APIs/tools that a third party would need to orchestrate.
Agenticness — how well agents can access and operate the productIssue scoped/least-privilege API credentials for an agent
nonemoves agent-readyimpact 30
SumUp docs describe API keys as static, account-wide credentials ('act on behalf of the merchant account that created the key') with no mention of scopes, permissions, or least-privilege options for agents or sub-credentials.
