AI agents use add_task to create or update resources in Compass MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Compass MCP environment.
This tool creates or adds new task entries to a task list, which is a reversible write operation. It does not delete data (not Destructive), does not involve financial transactions (not Financial), does not execute arbitrary code or commands (not Execute), and merely creates structured data entries (Write).
From the tool's definition Tool name 'add_task' and description 'Add a new task to your task list' indicate creation of new data in a task management system.
Documented attack patterns abuse exactly the kind of access add_task gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Compass MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for add_task:
{
"version": "1",
"default": "deny",
"tools": {
"add_task": {
"limits": [
{
"counter": "add_task_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_task 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.
Free to start. No card required.
Add a new task to your task list. It is categorised as a Write tool in the Compass MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Compass MCP server in PolicyLayer and add a rule for add_task: 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 Compass MCP. Nothing to install.
add_task 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 add_task 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 add_task. 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.
add_task is provided by the Compass MCP server (richlira/compass-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
