AI agents use add-project to create or update resources in SupaThings MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SupaThings MCP environment.
Creating a project in a task management system is a reversible Write operation—projects can be modified or deleted later. It modifies the application state but does not irreversibly destroy data, execute arbitrary code, or move money.
From the tool's definition Tool name 'add-project' combined with sibling tools like 'create-project-with-headings' and server description stating it 'enables AI agents to read and manage Things 3 data' indicates data modification capability.
Documented attack patterns abuse exactly the kind of access add-project gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SupaThings MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for add-project:
{
"version": "1",
"default": "deny",
"tools": {
"add-project": {
"limits": [
{
"counter": "add-project_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add-project 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.

add-project. It is categorised as a Write tool in the SupaThings MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the SupaThings MCP server in PolicyLayer and add a rule for add-project: 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 SupaThings MCP. Nothing to install.
add-project 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-project 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-project. 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-project is provided by the SupaThings MCP server (soycanopa/supathings-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SupaThings MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
