AI agents call get_channel to retrieve information from Playwright Stealth without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool purely retrieves and queries existing data about a channel without any side effects. It reads metadata and thread information, matching the Read category definition: 'retrieves or queries data; no side effects (search, list, get, fetch)'. The low severity reflects minimal blast radius—unauthorized access to channel metadata poses limited risk compared to tools that modify, execute, or delete data.
From the tool's definition Tool description states it 'Retrieve[s] detailed information about a specific Twist channel' and 'provides comprehensive metadata' including 'name, description, creation date, status, and optionally lists threads'.
Documented attack patterns abuse exactly the kind of access get_channel gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Playwright Stealth, and nothing reaches the server without passing your rules. This is the rule we recommend for get_channel:
{
"version": "1",
"default": "deny",
"tools": {
"get_channel": {}
}
}get_channel is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve detailed information about a specific Twist channel along with its threads. This tool provides comprehensive metadata about a channel including its name, description, creation date, status, and optionally lists threads within the channel. By default, it includes open threads but this can be disabled or customized. Example response: Channel Details: - Name: #engineering - ID: 123457 - Description: Engineering team updates and technical discussions - Workspace ID: 228287 - Status: Active - Created: 3/15/2024, 10:30:00 AM Threads (8 open threads): -. It is categorised as a Read tool in the Playwright Stealth MCP Server, which means it retrieves data without modifying state.
Register the Playwright Stealth MCP server in PolicyLayer and add a rule for get_channel: 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 Playwright Stealth. Nothing to install.
get_channel 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 get_channel 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 get_channel. 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.
get_channel is provided by the Playwright Stealth MCP server (pulsemcp/mcp-servers). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Playwright Stealth, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
