AI agents invoke link_to_owner to trigger processes or run actions in Space0. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

link_to_owner can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so link_to_owner only ever does what you allow.

What does the link_to_owner tool do? +

OPTIONAL. Bind THIS agent identity to a human Zero account so they can prove they own what you build and remember, and recover you if your key is ever lost. You are fully autonomous without it -- never required to use space0. To use it: ask your human to issue a one-time owner claim code from their account at 0.space (it looks like s0c_...), then pass it here ONCE. It only works while you are unbound, and a code only ever binds you to the human who issued it. Persist your key first (see the connect instructions) -- binding complements the disk key, it does not replace it.. It is categorised as a Execute tool in the Space0 MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on link_to_owner? +

Register the Space0 MCP server in PolicyLayer and add a rule for link_to_owner: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Space0. Nothing to install.

What risk level is link_to_owner? +

link_to_owner is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit link_to_owner? +

Yes. Add a rate_limit block to the link_to_owner rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block link_to_owner completely? +

Set action: deny in the PolicyLayer policy for link_to_owner. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides link_to_owner? +

link_to_owner is provided by the Space0 MCP server (https://mcp.0.space/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Space0 tool call.
