AI agents call bloom_list_behaviors to retrieve information from Msty Admin MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool simply enumerates or queries available Bloom behaviors without creating, modifying, deleting, or executing any operations. It is a pure information retrieval operation with minimal risk if misused by an AI agent.
From the tool's definition Tool name contains 'list' which retrieves data; description states 'List available Bloom behaviors' indicating a query/enumeration operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access bloom_list_behaviors gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Msty Admin MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for bloom_list_behaviors:
{
"version": "1",
"default": "deny",
"tools": {
"bloom_list_behaviors": {}
}
}bloom_list_behaviors is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List available Bloom behaviors. It is categorised as a Read tool in the Msty Admin MCP MCP Server, which means it retrieves data without modifying state.
Register the Msty Admin MCP server in PolicyLayer and add a rule for bloom_list_behaviors: 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 Msty Admin MCP. Nothing to install.
bloom_list_behaviors is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the bloom_list_behaviors 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 bloom_list_behaviors. 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.
bloom_list_behaviors is provided by the Msty Admin MCP server (m-pineapple/msty-admin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Msty Admin MCP, 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.
