Register the Network Device Assistant MCP server in PolicyLayer and add a rule for read_context_file: 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 Network Device Assistant. Nothing to install.
read_context_file 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 read_context_file 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 read_context_file. 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.
read_context_file is provided by the Network Device Assistant MCP server (mgarabito/network-device-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
read_context_file is one line of Network Device Assistant's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
