Checking is free. Everything you pay for is a run, a record or a seat.
Anyone can verify a record we sign, with open code and no account. Test before you ship, verify what you ship, admit only what passed.
Probity Test
For teams that build MCP servers and agent skills and want them tested before they ship.
$5,000 a year
Up to 15 developers. $15,000 a year covers up to 40. Then $30 per developer per month.
- Security scanning, the eval harness, load tests and one-shot scorecards.
- CI-only site: $5,000 a year, no seat count.
- No agent meter and no machine meter. We count developers.
Probity Verify
For anyone who must check a claim about an agent, and publishers who want theirs checked.
Free to check
No account, no key, no limit on checks. The verifier proves a record is signed and unchanged; what a run buys is a fresh, signed verdict about one specific version.
- The verifier:
pip install probity-verify==0.2.2 - The conformance corpus and its GitHub Action.
- The vocabulary, the admission rules and the observer sensors.
- Signed behavioural runs for publishers are opening to a founding cohort. Ask for a place.
Probity Admit
For security and platform teams that decide which servers their agents may load.
Priced per engagement.
Founding rate on request. A signed scorecard of your servers, in two to four weeks. Ask for the rate
- Three servers you name, then your catalogue.
- The open admission rules, run over your records in audit mode.
- The Test licence for the length of the engagement.
- Admission enforcement and the graded feed follow, and scorecard customers are first in line.
Built to be re-checked by someone else.
Auditors and assessors
Replay any record we sign, free, with the open verifier. A pilot is priced on use, as a line on your own engagement fee, and waived if your workpaper does not use the record. Priced per engagement. Founding rate on request. Ask for the rate
Gateways, registries and platforms
License our records and detection inside your product. Terms by agreement.
Four rules that do not move.
- We never sell a pass.
- You pay for the attempt, the seat or the engagement. A failing result is recorded the same way as a passing one, and payment never changes a verdict.
- Checking never needs paid code.
- Every record we sign verifies with the open verifier, offline, by anyone. That is what makes a record worth showing to a buyer.
- You pay per developer, not per agent.
- Your agent fleet can grow without your bill growing with it. We count developers, never machines.
- Founding rates.
- The prices on this page are founding rates. Customers who sign at them keep them for the term they sign.
Paid licences and services are sold by Probity, Inc. Prices are in US dollars, before tax.
