Update workspace-wide channel defaults (rate limits, timeouts, tool mode). These settings apply across all enabled channels: - maxSessionsPerDay: Cap on inbound chat sessions per day (default 100) - sessionTimeoutMinutes: Auto-close sessions after inactivity (default 60) - toolMode: 'all' (all to...

AI agents use set_channel_defaults to create or modify resources in Agentled. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call set_channel_defaults repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Agentled.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Update workspace-wide channel defaults (rate limits, timeouts, tool mode). These settings apply across all enabled channels: - maxSessionsPerDay: Cap on inbound chat sessions per day (default 100) - sessionTimeoutMinutes: Auto-close sessions after inactivity (default 60) - toolMode: 'all' (all tools available) or 'mcp' (MCP-only tools). It is categorised as a Write tool in the Agentled MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Agentled MCP server in PolicyLayer and add a rule for set_channel_defaults: 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 Agentled. Nothing to install.
set_channel_defaults 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 set_channel_defaults 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 set_channel_defaults. 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.
set_channel_defaults is provided by the Agentled MCP server (@agentled/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
