AI agents call bloom_check_handoff 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 retrieves or evaluates whether a handoff condition is met, returning a boolean or decision status without side effects. It does not modify data, execute external operations, delete anything, or move money. This is a Read category tool: it queries conditions/state to inform decisions but does not alter the system.
From the tool's definition Tool name 'bloom_check_handoff' and description 'Check if model should hand off to Claude' indicate a decision-checking operation.

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_check_handoff:
{
"version": "1",
"default": "deny",
"tools": {
"bloom_check_handoff": {}
}
}bloom_check_handoff is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Check if model should hand off to Claude. 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_check_handoff: 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_check_handoff 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_check_handoff 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_check_handoff. 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_check_handoff 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.
