AI agents use update_component to create or update resources in ResoniteLink MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ResoniteLink MCP environment.
An AI agent can call update_component faster than any human can review — one bad instruction and it creates or modifies resources in ResoniteLink MCP by the hundred, each call as confident as the last.
Documented attack patterns abuse exactly the kind of access update_component gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ResoniteLink MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for update_component:
{
"version": "1",
"default": "deny",
"tools": {
"update_component": {
"limits": [
{
"counter": "update_component_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_component 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 component member values. It is categorised as a Write tool in the ResoniteLink MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the ResoniteLink MCP server in PolicyLayer and add a rule for update_component: 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 ResoniteLink MCP. Nothing to install.
update_component 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_component 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_component. 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_component is provided by the ResoniteLink MCP server (rassi0429/resolink-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
