What graphql_scanner does on Nyxstrike
AI agents invoke graphql_scanner to trigger actions in Nyxstrike. 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.
Why graphql_scanner is rated High
The tool name 'graphql_scanner' strongly implies active scanning of GraphQL endpoints — an Execute-category action that probes external systems. The description is empty, so exact behavior is uncertain, but the offensive security context and sibling tools (payload generation, attack suites, vulnerability assessment) indicate this scans/interrogates remote GraphQL APIs, potentially exposing introspection data,…
From the tool's definition Tool name 'graphql_scanner' on a penetration testing platform ('AI Powered penetration testing Platform for offensive security research') alongside sibling tools like 'advanced_payload_generation', 'ai_generate_attack_suite', and 'ai_vulnerability_assessment'.
Attacks that exploit this kind of access
The rule that runs graphql_scanner safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Nyxstrike, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For graphql_scanner, this is the rule to start with:
graphql_scanner 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 Nyxstrike, apply this rule, and every graphql_scanner call is checked against it from then on.
Questions about graphql_scanner
graphql_scanner is a execute tool on the Nyxstrike MCP server. It is categorised as a Execute tool in the Nyxstrike MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Nyxstrike MCP server in PolicyLayer and add a rule for graphql_scanner: 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 Nyxstrike. Nothing to install.
graphql_scanner 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 graphql_scanner 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 graphql_scanner. 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.
graphql_scanner is provided by the Nyxstrike MCP server (CommonHuman-Lab/nyxstrike). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
