WHAT IT DOES

What bulk_index does on Ncp

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

RISK

Why bulk_index is rated Medium

Indexing is a write operation that creates or modifies data (index structures) but is reversible—indexes can be rebuilt or deleted without data loss. The 'bulk' aspect increases the blast radius to medium severity, as a misconfigured bulk operation could index large quantities of unintended documents or overwrite existing indexes.

From the tool's definition Tool name is 'bulk_index' with description 'Bulk index documents'. Indexing modifies data structures (creates or updates indexes) in a reversible manner.

RECOMMENDED RULE

The rule that runs bulk_index safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ncp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For bulk_index, this is the rule to start with:

bulk_index Rate-limited

bulk_index 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Ncp, apply this rule, and every bulk_index call is checked against it from then on.

What risk level is bulk_index? +

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

Can I rate-limit bulk_index? +

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

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