generate_policy · NORMA MCP Server MCP: Risk & Policy

WHAT IT DOES

What generate_policy does on NORMA MCP Server

AI agents use generate_policy to create or update resources in NORMA MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your NORMA MCP Server environment.

WHY IT NEEDS A POLICY

Why generate_policy needs a policy

This is a Write operation because it creates new policy documents based on templates and company-supplied parameters. The output is a generated compliance policy document. Severity is medium rather than high because: (1) policies are typically reversible/editable documents, (2) output includes a liability disclaimer, and (3) the tool operates within a bounded compliance template corpus (208 templates total).

From the tool's definition Tool generates and returns policy documents in Markdown format by parameterizing compliance templates with company context. Description explicitly states 'parametrize... and return Markdown,' indicating creation of new output artifacts.

Verdict

generate_policy Rate-limited

generate_policy 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.

Register the NORMA MCP Server MCP server in PolicyLayer and add a rule for generate_policy: 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 NORMA MCP Server. Nothing to install.

What risk level is generate_policy? +

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

Can I rate-limit generate_policy? +

Yes. Add a rate_limit block to the generate_policy 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.
