Show HN: AgentPort – Open-source Security Gateway For Agents
Hey HN!<p>I've been wanting to use something like OpenClaw for a while but couldn't get myself to give it access to anything important due to all the risks involved. Prompt injection is still a problem (even though some people seem to ignore it) and so are hallucinations and mishaps that cause agents to do things like delete production data [1].<p>Even harnesses like Claude Code and Codex are subject to this, particularly since we're getting progressively looser about how we run them e.g. Conductor is really popular and runs agents without any sandboxing.<p>That means we're in a bit of an all-or-nothing situation. There are people who just ignore the risks and connect everything to their agents and reap benefits from it while being subject to more risk, and there are others that just don't connect anything because they are mindful of the potential issues.<p>I've been quite cautious but have wanted to run more autonomous agents and so I built the component I needed to enable me to do so: AgentPort.<p>AgentPort is a gateway that connects to any service (e.g. Gmail, GitHub, Stripe, PostHog, Linear) and let's you set granular permissions for what the agent can do automatically, what it needs your approval for, and what it can never do.<p>For example, you can set `list_customers` and `get_customer` on the Stripe integration to "Auto-approve" but `create_refund` to "Ask for approval". The agent will thus be able to do a lot in the background independently but when it comes to a potentially destructive operation it will be blocked and receive an approval link to send to you. You can then approve or deny the call with those exact parameters e.g. `create_refund(customer_id: 1234, amount: 12)`.<p>Agents connect via MCP or CLI and have access to all the integrations you connected without ever getting API keys. Kind of like Composio but with granular permissions and open source.<p>The goal with AgentPort is to specifically address two vulnerabilities that agents are subject to:<p>1. Destructive operations on downstream services: It can't delete a database unless you explicitly approve 2. Credential exfiltration: Your agent never sees API keys<p>AgentPort also helps with sensitive data exfiltration, but that is more nuanced and complicated to defend against if the agent has an internet connection [2].<p>Ultimately, AgentPort was the missing piece for me to start running more autonomous agents that have access to third-party services, and hopefully it can unlock use cases for you too. There's a ton more work needed around securing agents (Claws in particular) and I've both been writing about it [3] and intend to do more in this space, so if you're thinking about similar things let's have a chat.<p>The repo is <a href="https://github.com/yakkomajuri/agentport" rel="nofollow">https://github.com/yakkomajuri/agentport</a> and you can run it locally with docker compose in a minute or use the one-liner install to deploy a prod instance (domain, TLS, etc.) in just a few mins as well.<p>[1] "An AI agent deleted our production database. The agent's confession is below" (<a href="https://news.ycombinator.com/item?id=47911524">https://news.ycombinator.com/item?id=47911524</a>)<p>[2] See my post "On agents dropping production databases": <a href="https://yakko.dev/blog/on-agents-dropping-production-dbs" rel="nofollow">https://yakko.dev/blog/on-agents-dropping-production-dbs</a><p>[3] <a href="https://yakko.dev/blog" rel="nofollow">https://yakko.dev/blog</a>
AgentPort addresses the critical 'trust gap' preventing enterprise adoption of autonomous agents by providing a granular permission and security gateway. While currently an early-stage open-source project, its alignment with the Model Context Protocol (MCP) and the urgent need for 'human-in-the-loop' safety for AI actions makes it a highly relevant infrastructure play.
