WHAT IT DOES

What region-query does on Frontmcp

AI agents invoke region-query to trigger actions in Frontmcp. 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.

RISK

Why region-query is rated High

Executes queries with region-routed HTTP operations; side effects depend on query content.

RECOMMENDED RULE

The rule that runs region-query safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Frontmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For region-query, this is the rule to start with:

region-query Rate-limited

region-query 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Frontmcp, apply this rule, and every region-query call is checked against it from then on.

FAQ

Questions about region-query

What does the region-query tool do? +

Runs a query in a given region; region is mirrored into an HTTP header. It is categorised as a Execute tool in the Frontmcp MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on region-query? +

Register the Front MCP server in PolicyLayer and add a rule for region-query: 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 Frontmcp. Nothing to install.

What risk level is region-query? +

region-query is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit region-query? +

Yes. Add a rate_limit block to the region-query 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.

How do I block region-query completely? +

Set action: deny in the PolicyLayer policy for region-query. 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.

What MCP server provides region-query? +

region-query is provided by the Front MCP server (agentfront/frontmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
