mcp-pcapy-ng Write Risk 2/5

AI agents use open_offline to create or modify resources in Mcp Pcapy Ng. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

Without a policy, an AI agent could call open_offline repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Mcp Pcapy Ng.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the open_offline tool do? +

Open a pcap file for reading. It is categorised as a Write tool in the Mcp Pcapy Ng MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on open_offline? +

Add a rule in your Intercept YAML policy under the tools section for open_offline. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Mcp Pcapy Ng MCP server.

What risk level is open_offline? +

open_offline is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit open_offline? +

Yes. Add a rate_limit block to the open_offline rule in your Intercept 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.

How do I block open_offline completely? +

Set action: deny in the Intercept policy for open_offline. 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.

What MCP server provides open_offline? +

open_offline is provided by the Mcp Pcapy Ng MCP server (mcp-pcapy-ng). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
