How to choose an AI agent marketplace in 2026
An agent marketplace should not be judged only by its number of listings or connectors. It must let an owner understand who is acting, under which policy, and what remedy exists when a transaction fails.
Selection criteria
- 1. Start with the use case and autonomy level
- 2. Verify identity, reputation, and listing quality
- 3. Examine permissions, budgets, and audit
- 4. Understand payments, disputes, and data
- 5. Use a repeatable evaluation scorecard

/1. Start with the use case and autonomy level
Separate deal discovery, listing publication, and purchasing. A price-comparison agent can stay read-only; an agent that negotiates or pays requires identity, budgets, and approval. Rule out platforms that cannot limit these capabilities precisely.
- List required actions and those that must remain forbidden.
- Define the markets, languages, and currencies actually needed.
- Test a non-critical transaction before expanding access.
/2. Verify identity, reputation, and listing quality
Look for a revocable identity per agent, a clear separation between owner and agent, and explainable reputation signals. For listings, examine moderation, duplicate handling, freshness, and reporting workflows.
/3. Examine permissions, budgets, and audit
The platform should enforce rules server-side, not merely describe them in a prompt. Check per-action permissions, currency-aware caps, approval gates, idempotency, and revocation. Audit records should connect identity, request, human decision, and outcome.
- Simulate a purchase above the cap.
- Deny an approval and verify the action stays blocked.
- Revoke the credential and confirm that it takes effect immediately.
/4. Understand payments, disputes, and data
Before delegating a purchase, clarify the platform's role in payment, delivery, contact reveal, and disputes. Read fees, timing, refund terms, and evidence retention. Check which data reaches the model, seller, and service providers.
- Identify jurisdiction and applicable terms.
- Verify the dispute path and accepted evidence.
- Prefer data minimisation and short-lived credentials.
/5. Use a repeatable evaluation scorecard
Assign observable evidence to each criterion: documentation, a test, an audit export, or sandbox behaviour. Compare products with the same weighting. A smooth demo cannot compensate for missing revocation, budget controls, or recourse.
- Security and governance: identity, scopes, approvals, audit.
- Market quality: freshness, moderation, reputation, local coverage.
- Operations: availability, limits, support, export, and reversibility.
- Economics: total fees, connector cost, and maintenance effort.
/Marketplace evaluation scorecard
| Criterion | Evidence to request | Warning sign |
|---|---|---|
| Publisher and artifact | Publisher identity, version, changelog, and integrity information | No attributable publisher or mutable unversioned artifact |
| Permissions | Declared tools, data access, outbound domains, and least-privilege defaults | Broad or hidden permissions |
| Transaction controls | Budgets, approval boundaries, idempotency, and revocation | The agent can commit an irreversible action without an external gate |
| Audit and incidents | Request-level logs, correction channel, and response procedure | No trace linking a decision to its outcome |
/Frequently asked questions
Is a large catalogue proof that a marketplace is safe?
No. Catalogue size does not establish publisher identity, artifact integrity, permission quality, transaction controls, or incident response. Evaluate those controls directly.
What should I inspect before installing an agent skill?
Check the publisher, version, source or artifact, requested permissions, outbound access, update history, revocation path, and how sensitive actions are approved and audited.
Can a trust score replace my own policy?
No. A score can help prioritise review, but your policy should independently enforce allowed tools, budgets, approval thresholds, and revocation.
