bootstrap · Ebony Enriching MCP: Risk & Policy

WHAT IT DOES

What bootstrap does on Ebony Enriching

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

WHY IT NEEDS A POLICY

Why bootstrap needs a policy

Bootstrap initializes a new lab notebook structure at a configured location. This is a Write operation as it creates new filesystem storage structures. It could overwrite existing state if run on an already-initialized instance, but the description suggests it sets up an empty structure, implying initial creation.

Verdict

bootstrap Rate-limited

bootstrap 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 bootstrap

What does the bootstrap tool do? +

Initialize an empty EbonyEnriching at the configured. It is categorised as a Write tool in the Ebony Enriching MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on bootstrap? +

Register the Ebony Enriching MCP server in PolicyLayer and add a rule for bootstrap: 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 Ebony Enriching. Nothing to install.

What risk level is bootstrap? +

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

Can I rate-limit bootstrap? +

Yes. Add a rate_limit block to the bootstrap 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 bootstrap completely? +

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

bootstrap is provided by the Ebony Enriching MCP server (parkviewlab/ebony-enriching). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
