Golem watches every action your AI agents take, blocks the dangerous ones the moment they happen, and keeps a tamper-proof record you own — so you can finally prove what an agent did, and stop it when it goes wrong. Not a log the agent wrote about itself; proof that survives a hostile question.

Why this exists
It reads untrusted content, calls tools, hits the network — headlessly, faster than you can watch. Three questions have no good answer today.
A poisoned web page or PR comment can turn your agent against you — the lethal trifecta. Nothing checks the URL or tool call at the moment it fires.
“An agent called an endpoint” is not evidence. Logs can be edited. You can't prove which agent, with what scope, touched what — after the fact.
Shadow MCP servers, unvetted tool calls, silent token burn. The agent surface grows faster than anyone's map of it.
True attestation
“Check the logs” fails the moment it matters. The record of an action has to be captured by something other than the actor — and be tamper-evident — or it proves nothing. Planes have flight recorders the pilot can't edit. We shipped agents with production credentials and skipped that step. Golem is the witness.
LangSmith, Langfuse, Datadog help you make the agent better — self-reported traces in a store you don't control. Golem proves what it actually did.
Gateways and guardrails try to stop bad things; the logs are a byproduct. Golem proves what happened — including proving the control worked.
Policies and model cards don't survive a subpoena. A signed, tamper-proof record — with the raw data still in your storage — does.
Secure every tool & MCP call
Golem sits inline, so every action your agent takes runs this path. The highlighted step is the one only an inline layer can do: decide and record at the exact moment of action.
Golem sits in front of everything your agent touches — its commands, its edits, its network calls, its AI-model traffic, even the browser. It watches from outside the agent, not from a library the agent controls. And because it sits in the middle, it can act, not just observe.
Because every call passes through it, Golem can let it through, block it outright, or hold it for a human — the edit, the shell command, the deploy, the fetch to a sketchy host, each one stoppable at the wire. Run /safely before a risky task and it locks the agent down to a safe, allow-listed set of tools it can't widen from inside the session. Everyone blocks things; the point is that afterward you can prove the block worked.
Every action is sealed with a cryptographic signature and linked to the one before it — change any past record and the break is obvious. The signing key can be locked to the machine itself, so a signature ties to a real device. And nothing is ever lost, even if the network blips.
Raw payloads are split off and written to your own storage — S3, GCS, Azure, or local. The hosted plane only ever holds hashes and signatures. Your data never leaves your infrastructure.
Open the console to the Agentic Security Graph, a shadow-AI inventory, a review queue, and one-click compliance-evidence export. It even flags ghost sessions — a session that spawned a background process and then went dark. The agent was headless; the human arrives to control.
A full security stack, built for agents
Not an after-the-fact log. A control point that sees every action, stops the dangerous ones, and turns the rest into evidence you own.
Golem watches your agents from the outside — your IDE, your coding agents, your AI-model calls, even the browser. A record the agent writes about itself isn't evidence. This is.

what · when · with what contextGolem checks the target of every call against known threats and your own policy, then allows it, blocks it, or holds it for a human — before anything happens. And proves the block worked.
before the action landsA one-way safety lock. /safely restricts the agent to a safe set of tools — blocking edits, shell commands, and the rest — and only a human can loosen it, never the agent. So content that tries to hijack your agent can't widen its own reach.
Bring Your Own Bucket. Raw prompts and payloads live in your S3/GCS/Azure/local storage. Golem proves that it happened without ever holding the content.
S3 · GCS · Azure · localSignatures can be bound to a key that never leaves real hardware — a TPM 2.0 on Linux or Apple's Secure Enclave — so a signature ties to a specific machine, not just a process.

Each agent gets its own short-lived, revocable identity. The record shows exactly which agent did what — proven by the signature itself, not just claimed by the agent.

Golem rides the Model Context Protocol, so it wraps the tools you already run — usually in one line of config. No rewrite, no SDK lock-in.
For agents and humans
The agent onboards for its own benefit; the human converts for control. Both live on one inline layer.

AI-native · agents defending agents
The thing that watches an agent can't be the agent. So Golem is AI-native to the core: every action is embedded and handed back through its own MCP server — so agents can investigate agents, and the guardrails that come out of it keep the whole fleet safe.
Every action is indexed the moment it happens, so an agent can ask — in plain language — what another agent did, replay a whole session, and confirm nothing was tampered with. No dashboard required.
ask in plain languageWrite a rule once — “never touch production right after reading untrusted content” — and it watches every agent automatically, forever. The whole fleet learns from one golem's catch.
write once · watches everyoneSafety verdicts and /safely clamps ride the same wire, so a guardrail earned on one host protects the next agent that connects. Golems watching golems.
The defensible middle
A sandbox asks “how much can it break?” Golem asks “should this action happen — and can you prove what did?”
Prompt injection rides your agent's own credentials and permissions, so a sandbox can't catch it — it's a question of what the agent is allowed to do, not how far it can reach. Golem is the only layer that can both stop an action and prove it happened, from the same point inline. That signed, tamper-proof record is exactly the evidence EU AI Act Article 12, SOC 2, and ISO 27001 ask for — which isolation can't produce.
