For product and engineering leads at B2B software companies

We measure whether an agent can actually finish work in your product.

We test whether an AI assistant can complete five concrete tasks in your product on its own. After the fix, we run the same tasks again.

Request a diagnostic How it works

What we do

Not a server generator. Evidence that the work gets finished.

Turning an OpenAPI file into an MCP server is straightforward today. That does not tell you whether an assistant can complete a job in your product. That is what we measure. The report records the outcome, the cause, and what should change — for example, listing invoices that were rejected and explaining why.

  • Five agreed tasks

    Written in the language of your product. For each one: pass or fail, the trace of the steps, and the cause if it does not complete.

  • Only what blocks completion

    If there is no usable assistant interface, we put a small, usually read-only one in place. If you already have a server, we harden it within the agreed scope.

  • The same measurement afterwards

    After the fix, the same five tasks run again. The figure you can compare is the number that pass, before and after.

  • A report, not a promise

    You keep the report and the traces. This site does not sell a hosted platform and does not take payment.

  • Further runs, if you want them

    The same tasks can be run again after a relevant release, or on an agreed cadence. That is not a mandatory subscription; it comes up after the first measurement.

How it works

Three steps. The number always comes from the same five tasks.

The diagnostic usually takes five working days once the tasks are agreed and we have access to the agreed environment.

  1. Diagnostic

    We agree five tasks, run them with an assistant, and record the outcome, the trace, and the cause. The report is the deliverable.

  2. Fix

    Only if tasks fail or a suitable interface is missing. The work follows a written mandate; write access is never assumed.

  3. Re-measure

    The same five tasks, against the same bar. You can stop there, or agree further runs.

If you sell into Germany

E-invoicing in 2027 is a product question, not a scare story.

Operational context only. This is not legal advice.

In Germany, domestic businesses have been required to receive structured electronic invoices since 1 January 2025. Issuing is being phased in. From 1 January 2027, businesses whose prior-year turnover exceeded €800,000 generally have to issue e-invoices for taxable domestic B2B supplies. Issuers at or below that threshold, and certain EDI arrangements, may use the transitional rule until the end of 2027; from 2028 the issuing obligation extends to the remaining businesses in scope. A plain PDF has not counted as an e-invoice under the German definition since 2025. See the Federal Ministry of Finance FAQ.

If your product helps German businesses issue invoices, we can measure whether an assistant can finish the related work in your product — for example, produce a structured invoice or read its status — and fix what fails. We do not determine legal conformity.

FAQ

Common questions

For anything else, use the form. We typically reply within one business day.

Do you host a platform that holds our data?

No. The measurement runs in an agreed environment. We do not operate a marketplace or a hosted agent platform for your customers from this site.

What does the diagnostic cost?

There are no prices on this page. After you write, we confirm the scope and send an offer. Nothing is charged here.

Do you need access to production?

We prefer a staging or test environment and, where possible, read-only credentials. Write steps only with a written mandate.

Is this a legal review of e-invoicing rules?

No. We measure whether an assistant can complete agreed tasks in your product. Legal conformity is not what this report decides.

What if we already have an MCP server?

The first question is still whether the five tasks succeed. The fix can be limited to hardening what you already run, rather than building a new server.
