AI agents use taskComplete to create or update resources in Mcp Taskade — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Taskade environment.
This tool modifies data (task status) in a reversible manner—a completed task can typically be reopened or its status changed back. It does not delete data, execute arbitrary code, or move money. The medium severity reflects that incorrect use could alter project state, but the change is recoverable.
From the tool's definition Tool name 'taskComplete' and description 'Complete a task in a project' indicate a state-change operation that modifies task status.
Documented attack patterns abuse exactly the kind of access taskComplete gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Taskade, and nothing reaches the server without passing your rules. This is the rule we recommend for taskComplete:
{
"version": "1",
"default": "deny",
"tools": {
"taskComplete": {
"limits": [
{
"counter": "taskcomplete_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}taskComplete 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.
Complete a task in a project. It is categorised as a Write tool in the Mcp Taskade MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Taskade MCP server in PolicyLayer and add a rule for taskComplete: 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 Mcp Taskade. Nothing to install.
taskComplete 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 taskComplete 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 taskComplete. 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.
taskComplete is provided by the Mcp Taskade MCP server (taskade/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
