Search the knowledge graph using hybrid (keyword + vector) search.
AI agents call axon_pro_query to retrieve information from Axon Pro without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs search and retrieval operations on a knowledge graph. It does not create, modify, delete, or execute code. The hybrid search capability (keyword + vector) is a standard read operation that retrieves information without altering the underlying data or triggering external operations. No financial implications or destructive actions are possible.
From the tool's definition Tool description states 'Search the knowledge graph using hybrid (keyword + vector) search.' Search operations are read-only queries with no side effects.
Documented attack patterns abuse exactly the kind of access axon_pro_query gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Axon Pro, and nothing reaches the server without passing your rules. This is the rule we recommend for axon_pro_query:
{
"version": "1",
"default": "deny",
"tools": {
"axon_pro_query": {}
}
}axon_pro_query is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search the knowledge graph using hybrid (keyword + vector) search. It is categorised as a Read tool in the Axon Pro MCP Server, which means it retrieves data without modifying state.
Register the Axon Pro MCP server in PolicyLayer and add a rule for axon_pro_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 Axon Pro. Nothing to install.
axon_pro_query 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 axon_pro_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.
Set action: deny in the PolicyLayer policy for axon_pro_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.
axon_pro_query is provided by the Axon Pro MCP server (talhamsajid/axon-pro). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
