WHAT IT DOES

What import_vectors does on Mcpg

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

RISK

Why import_vectors is rated Medium

The tool loads external vector data into a PostgreSQL database, which is a write operation that modifies database state. While reversible (can be deleted), the scope could be large (bulk import) and impact production systems. Classified as Write rather than Destructive since imports are typically reversible.

From the tool's definition Tool name 'import_vectors' on a PostgreSQL MCP server indicates data insertion/loading. The name directly suggests bulk data import operations.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs import_vectors safely

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

import_vectors Rate-limited

import_vectors 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 Mcpg, apply this rule, and every import_vectors call is checked against it from then on.

FAQ

Questions about import_vectors

What does the import_vectors tool do? +

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

How do I enforce a policy on import_vectors? +

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

What risk level is import_vectors? +

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

Can I rate-limit import_vectors? +

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

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

import_vectors is provided by the Mcpg MCP server (pypi:mcpg). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
