What c4_export does on C4REQBER
AI agents use c4_export to create or update resources in C4REQBER, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your C4REQBER environment.
Why c4_export is rated Medium
The name 'export' typically implies writing or exporting data (a reversible operation), which falls under the Write category. However, without a description, confidence is reduced. If export creates files or serializes data, it modifies state (Write). The medium severity reflects potential for batch data extraction or format conversion that could have downstream effects, though it remains reversible.
From the tool's definition Tool name 'c4_export' suggests exporting data; description is empty, providing no direct evidence of function or side effects.
Attacks that exploit this kind of access
The rule that runs c4_export safely
PolicyLayer is an MCP gateway: it sits between your AI agents and C4REQBER, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For c4_export, this is the rule to start with:
c4_export stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect C4REQBER, apply this rule, and every c4_export call is checked against it from then on.
Questions about c4_export
c4_export is a write tool on the C4REQBER MCP server. It is categorised as a Write tool in the C4REQBER MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the C4REQBER MCP server in PolicyLayer and add a rule for c4_export: 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 C4REQBER. Nothing to install.
c4_export is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the c4_export 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 c4_export. 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.
c4_export is provided by the C4REQBER MCP server (C4MIND/C4REQBER). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
