Fetch one task-scoped browser lane including live target ids and counters.
AI agents call oc_lane_get to retrieve information from OpenChrome without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about a browser lane (a scoped automation context) including identifiers and counters. It has no side effects—it only reads/queries the state of an existing lane. There is no creation, modification, deletion, code execution, or financial impact. This is a straightforward Read operation with low severity since the information exposed is internal browser automation state.
From the tool's definition Tool name 'oc_lane_get' and description 'Fetch one task-scoped browser lane' indicate a retrieval operation. The verb 'Fetch' and the specification of reading 'live target ids and counters' describe querying state without modification.

PolicyLayer is an MCP gateway — it sits between your AI agents and OpenChrome, and nothing reaches the server without passing your rules. This is the rule we recommend for oc_lane_get:
{
"version": "1",
"default": "deny",
"tools": {
"oc_lane_get": {}
}
}oc_lane_get is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Fetch one task-scoped browser lane including live target ids and counters. It is categorised as a Read tool in the OpenChrome MCP Server, which means it retrieves data without modifying state.
Register the OpenChrome MCP server in PolicyLayer and add a rule for oc_lane_get: 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 OpenChrome. Nothing to install.
oc_lane_get is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the oc_lane_get 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 oc_lane_get. 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.
oc_lane_get is provided by the OpenChrome MCP server (shaun0927/openchrome). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
