Load all tools from a specific category
AI agents invoke load_category_tools to trigger actions in Supabase MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool triggers an internal operation that loads and activates tools from a specified category, which could enable further high-severity operations. It doesn't read, write, or delete data directly, but it executes a configuration/activation action whose effects depend on which category is loaded.
From the tool's definition 'Load all tools from a specific category' — dynamically loads/activates tool sets within the MCP server
Documented attack patterns abuse exactly the kind of access load_category_tools gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Supabase MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for load_category_tools:
{
"version": "1",
"default": "deny",
"tools": {
"load_category_tools": {
"limits": [
{
"counter": "load_category_tools_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}load_category_tools stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Load all tools from a specific category. It is categorised as a Execute tool in the Supabase MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Supabase MCP Server MCP server in PolicyLayer and add a rule for load_category_tools: 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 Supabase MCP Server. Nothing to install.
load_category_tools is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the load_category_tools 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 load_category_tools. 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.
load_category_tools is provided by the Supabase MCP Server MCP server (quegenx/supabase-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Supabase MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
