adr · Kb MCP: Risk & Policy

WHAT IT DOES

What adr does on Kb

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

WHY IT NEEDS A POLICY

Why adr needs a policy

ADR (Architecture Decision Record) tools typically create or update decision record documents, which would be a Write operation. However, the description is empty, so this is inferred from common convention and the server context of 'note storage' and 'persistent knowledge'. Confidence is low due to lack of description.

From the tool's definition Tool name 'adr' likely refers to Architecture Decision Records; description is empty and uninformative.

Verdict

adr Rate-limited

adr 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.

FAQ

Questions about adr

What does the adr tool do? +

adr. It is categorised as a Write tool in the Kb MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on adr? +

Register the Kb MCP server in PolicyLayer and add a rule for adr: 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 Kb. Nothing to install.

What risk level is adr? +

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

Can I rate-limit adr? +

Yes. Add a rate_limit block to the adr 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.

How do I block adr completely? +

Set action: deny in the PolicyLayer policy for adr. 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 adr? +

adr is provided by the Kb MCP server (okash1n/kb). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
