Use Case Recommendations
Best for: AgentPort
AgentPort is an open-source security gateway that sits between AI agents and the tools they call, so an agent's access to production systems is governed by policy rather than by whichever API keys happened to end up in its environment. Agents connect through either an MCP server or a CLI, and from there reach Linear, Slack, GitHub, Notion, Stripe and dozens of other connectors that ship out of the box, plus any additional MCP server or REST API you point it at. The control layer is where the value sits: you define which tools a given agent may call outright, which require a human approval before execution, and — for the more cautious — advanced rule-based filtering that can gate on the shape of the call rather than just its name. Every tool call and every approval chain is written to an audit log, which turns an agent's behaviour from something you infer from outcomes into something you can read after the fact. This is the missing piece in most agent deployments: the agent framework decides what to attempt and the credential decides what is possible, with nothing in between. Deployment is either self-hosted from the open-source repository on your own infrastructure, or a managed cloud service currently in beta. AgentPort is built by Skald Labs, based in San Francisco.
Ideal use cases:
- •Teams or individuals who need mcp server and cli entry points for any agent
- •Teams or individuals who need dozens of built-in connectors including linear, slack, github, notion and stripe
- •Teams or individuals who need per-tool allow, deny and human-approval policies
- •Teams or individuals who need advanced rule-based filtering on individual tool calls
- •Anyone focused on agents workflows
- •Anyone focused on mcp workflows
Best for: Kakunin
Kakunin is compliance infrastructure that applies KYC-style identity to AI agents. Each agent is registered and certified in under three seconds, at which point AWS KMS issues an X.509 certificate binding the agent's identity, its operator and the actions it is permitted to take — the argument being that API keys carry no provenance and no revocation story, while certificates do. From there every agent action, decision and transaction streams to an ingest endpoint rated at 1,000 events per second with p99 latency around 200ms, building an append-only immutable audit log. Behavioural drift detection runs continuously against that stream, and content-risk scoring grades what the agent said rather than only what it did, producing a rolling 30-day trust score with automatic revocation below a 0.85 threshold. Public verification of an agent passport resolves in under 500ms. The output most buyers care about is the last step: one API call generates a regulator-ready compliance report as signed PDF and JSON, mapped to NIST AI RMF, the EU AI Act, MiCA, ISO 27001 or another of the six frameworks it covers. Pricing is per certified agent rather than per seat, with a 30-day free trial and optional bring-your-own-account alert channels for Slack, PagerDuty and Twilio SMS or WhatsApp.
Ideal use cases:
- •Teams or individuals who need x.509 certificate issuance via aws kms
- •Teams or individuals who need immutable append-only audit log at 1,000 events/sec
- •Teams or individuals who need behavioural drift detection and content-risk scoring
- •Teams or individuals who need rolling 30-day trust score with auto-revoke
- •Anyone focused on compliance workflows
- •Anyone focused on agents workflows
