Get the current context (corp and site names)
AI agents call get_context to retrieve information from Fastly NGWAF MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves current context information (corporate and site names) which is a read-only operation. It has no ability to modify, execute, or delete data. The blast radius is minimal as it only returns existing state information needed for reference.
From the tool's definition Tool name 'get_context' and description 'Get the current context (corp and site names)' indicate a query operation that retrieves configuration metadata without modification or side effects.

Register the Fastly NGWAF MCP Server MCP server in PolicyLayer and add a rule for get_context: 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 Fastly NGWAF MCP Server. Nothing to install.
get_context 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 get_context 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 get_context. 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.
