Execute a raw Cypher query against the knowledge graph.
AI agents invoke axon_pro_cypher to trigger actions in Axon Pro. 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 allows execution of arbitrary Cypher queries against the knowledge graph backend. While Cypher queries themselves are typically read-oriented in a graph database context, the word 'raw' combined with 'execute' indicates unfettered query capability.
From the tool's definition "Execute a raw Cypher query against the knowledge graph." The tool permits execution of arbitrary queries against a database without apparent restrictions or guardrails.
Documented attack patterns abuse exactly the kind of access axon_pro_cypher 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_cypher:
{
"version": "1",
"default": "deny",
"tools": {
"axon_pro_cypher": {
"limits": [
{
"counter": "axon_pro_cypher_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}axon_pro_cypher 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.
Free to start. No card required.
Execute a raw Cypher query against the knowledge graph. It is categorised as a Execute tool in the Axon Pro MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Axon Pro MCP server in PolicyLayer and add a rule for axon_pro_cypher: 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_cypher 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 axon_pro_cypher 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_cypher. 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_cypher 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.
