Execute a read-only Cypher query.
AI agents call graph_query to retrieve information from Ultimate MCP Coding Platform without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Read-only queries cannot modify, delete, or execute arbitrary code. While Cypher is a query language that could theoretically be misused for injection attacks if inputs are unsanitized, the read-only constraint fundamentally limits the blast radius to information disclosure rather than data manipulation or destructive operations.
From the tool's definition Tool description explicitly states 'Execute a read-only Cypher query.' The 'read-only' modifier and the Neo4j context (graph queries against a database) confirm this retrieves data without side effects.
Attacks that exploit this kind of access
Execute a read-only Cypher query. It is categorised as a Read tool in the Ultimate MCP Coding Platform MCP Server, which means it retrieves data without modifying state.
Register the Ultimate MCP Coding Platform MCP server in PolicyLayer and add a rule for graph_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 Ultimate MCP Coding Platform. Nothing to install.
graph_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 graph_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 graph_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.
graph_query is provided by the Ultimate MCP Coding Platform MCP server (senpai-sama7/ultimate_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
