Type text into an input field
AI agents use interact.type to create or update resources in LCBro — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your LCBro environment.
This tool writes data into form fields, which is a reversible operation (text can be cleared or overwritten). While it doesn't create permanent records by itself, it prepares data for form submission and could be misused to inject malicious input, flood fields, or populate forms without authorization.
From the tool's definition Tool name 'interact.type' and description 'Type text into an input field' indicate the tool modifies input field state by writing text, creating reversible changes to web forms.
Documented attack patterns abuse exactly the kind of access interact.type gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and LCBro, and nothing reaches the server without passing your rules. This is the rule we recommend for interact.type:
{
"version": "1",
"default": "deny",
"tools": {
"interact.type": {
"limits": [
{
"counter": "interact.type_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}interact.type 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.

Type text into an input field. It is categorised as a Write tool in the LCBro MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the LCBro MCP server in PolicyLayer and add a rule for interact.type: 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 LCBro. Nothing to install.
interact.type 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 interact.type 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 interact.type. 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.
interact.type is provided by the LCBro MCP server (lcbro/lcbro-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from LCBro, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
