Pynt: cost, fit and limits
Pynt is an API security testing platform made by Pynt, Inc. that builds attack tests from real traffic, runs them from a CLI or CI pipeline and adds discovery of LLM APIs and an MCP runtime firewall for developers and security teams.
What to know first
Pynt shows a Start Free button and a demo request but no plan names, limits or prices on its pricing page. The product list covers API discovery, behavior-based testing, LLM security testing and an agent-based MCP firewall. Its integration list is more specific than most rivals, from Postman and Burp to Kong, GitHub Actions and Jira. Ask for a trial scope in writing.

Who Pynt is best for
Teams that test from Postman
Native Postman and Burp integrations plus HAR file input let a QA team feed existing collections into security tests instead of writing new ones.
CI-first engineering groups
Pynt runs via a CLI with JSON output and lists GitHub Actions, GitLab, Jenkins and Azure DevOps, so tests can gate a build.
Teams adding LLM features
LLM Discovery finds LLM APIs referenced in code, and LLM Security Testing checks them against the OWASP LLM Top 10.
Pynt plans and pricing
| Plan | Price | What it includes |
|---|---|---|
| Start Free | Free, terms not shown | A Start Free button is on the pricing page, but the page lists no limits, duration or features for it. |
| Demo-led plans | Quote only | The page shows no tier names or prices and offers a demo request for scoped pricing. |
| MCP Runtime | Not shown on the page | An agent-based firewall that can fully disable or control MCP tools, listed as a product line without separate pricing. |

What Pynt does
- Live-traffic API inventory
- Discovery builds an inventory from live traffic and finds shadow and undocumented endpoints, using what the application does instead of only what the spec says.
- Behavior-based testing
- Tests are built from observed behavior, so they follow real request sequences, which helps with authorization checks that need valid sessions and object IDs. That reduces hand-written test cases.
- LLM security testing
- LLM endpoints are checked against the OWASP LLM Top 10, alongside LLM Discovery that finds model APIs referenced in code. The page does not list the number of checks per category.
- MCP Runtime firewall
- An agent-based firewall sits between agents and MCP tools and can disable or control individual tools, which limits what an agent may call. It targets agent-to-tool traffic rather than human users.
- Pipeline and gateway integrations
- The page lists AWS, Kong and Azure gateways, Newman, Rest Assured, ReadyAPI, Insomnia and Kubernetes, plus Jira for ticketing. Coverage reaches both build and runtime stages.
How Pynt handles your data
The privacy policy names Pynt, Inc. at 108 W. 13th Street, Wilmington, Delaware, and says data is stored and processed by Pynt or by hosting providers in the EU, the US and other regions, without naming vendors. It states that information is encrypted in transit and at rest, that Pynt does not sell personal information, and that EU standard contractual clauses cover transfers. Retention follows business and legal needs, with deleted data persisting in backups. AI training was not addressed.
Where Pynt falls short in practice
- No pricing structure. Neither tiers nor limits appear. A team cannot tell whether the free start covers a CI run or only a demo, so test it on a real pipeline.
- Conflicting proof points. The same page cites 500 brands in one section and 2000 in another. Treat counts as marketing and ask for references that match your sector.
- No named certification. The page points to a trust center instead of naming SOC 2 or ISO status. Security reviewers should read that trust center before shortlisting. Ask for the trust center URL.

Alternatives to Pynt
Pynt: common questions
Does Pynt have a free plan?
The pricing page shows a Start Free option, but it states no limits, duration or features, and it offers a demo request for scoped pricing. Try the free start on a staging API and note scan limits, report access and CI support before planning a rollout.
How does Pynt generate API tests?
The product list describes behavior-based discovery and testing built from traffic and existing artifacts such as Postman collections and HAR files. It runs through a CLI with JSON output. The page does not publish a method for how tests are derived, so judge it on your own APIs.
Can Pynt test LLM APIs?
Yes. LLM Discovery finds LLM APIs referenced in code and LLM Security Testing checks them against the OWASP LLM Top 10. The page does not list test counts or model coverage, so ask which attack classes are included in your plan.
What is the Pynt MCP Runtime?
It is described as an agent-based firewall that can fully disable or control MCP tools. The page gives few technical details and no pricing, so request an architecture note on where the firewall runs and what it can see. Ask for a diagram.
Where does Pynt store customer data?
The privacy policy says data may be stored and processed in the EU, the US and other regions, via hosting providers it does not name. It cites standard contractual clauses for transfers. If you need one region only, ask for it in the contract.
