Update configuration for a tool in your collection.
AI agents use update_tool_config to create or update resources in Automagik Tools — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Automagik Tools environment.
This tool creates or modifies data (tool configurations) in a reversible manner, fitting the Write category. The severity is medium because misconfiguration could impact tool behavior and potentially affect downstream operations, but the changes are not irreversible (can be reconfigured).
From the tool's definition Tool name 'update_tool_config' indicates modification of existing configuration data. Description states 'Update configuration for a tool in your collection,' which is a reversible write operation that modifies settings without irreversible deletion.
Documented attack patterns abuse exactly the kind of access update_tool_config gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Automagik Tools, and nothing reaches the server without passing your rules. This is the rule we recommend for update_tool_config:
{
"version": "1",
"default": "deny",
"tools": {
"update_tool_config": {
"limits": [
{
"counter": "update_tool_config_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_tool_config 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.

Update configuration for a tool in your collection. It is categorised as a Write tool in the Automagik Tools MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Automagik Tools MCP server in PolicyLayer and add a rule for update_tool_config: 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 Automagik Tools. Nothing to install.
update_tool_config 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 update_tool_config 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 update_tool_config. 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.
update_tool_config is provided by the Automagik Tools MCP server (namastexlabs/automagik-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Automagik Tools, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
