AI agents use goclaw_skill_grant_agent to create or update resources in GoClaw MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GoClaw MCP Server environment.
Granting access is a permission/authorization write operation that modifies an agent's access control configuration. It is reversible (access can be revoked), so it falls under Write rather than Destructive. Misuse could allow an agent to access unintended capabilities, giving it medium severity.
From the tool's definition Grant an agent access to a skill
Documented attack patterns abuse exactly the kind of access goclaw_skill_grant_agent gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and GoClaw MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for goclaw_skill_grant_agent:
{
"version": "1",
"default": "deny",
"tools": {
"goclaw_skill_grant_agent": {
"limits": [
{
"counter": "goclaw_skill_grant_agent_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} goclaw_skill_grant_agent stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Grant an agent access to a skill. It is categorised as a Write tool in the GoClaw MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the GoClaw MCP Server MCP server in PolicyLayer and add a rule for goclaw_skill_grant_agent: 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 GoClaw MCP Server. Nothing to install.
goclaw_skill_grant_agent is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the goclaw_skill_grant_agent 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.
Set action: deny in the PolicyLayer policy for goclaw_skill_grant_agent. 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.
goclaw_skill_grant_agent is provided by the GoClaw MCP Server MCP server (nextlevelbuilder/goclaw-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from GoClaw MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
