create_tensor_descriptor · Tensorus MCP: Risk & Policy

WHAT IT DOES

What create_tensor_descriptor does on Tensorus MCP

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

WHY IT NEEDS A POLICY

Why create_tensor_descriptor needs a policy

This tool creates a new descriptor object in the Tensorus tensor database, which is a reversible write operation. It does not execute arbitrary code, delete data irreversibly, move money, or merely read existing data.

From the tool's definition Tool name 'create_tensor_descriptor' and description 'Create a new tensor descriptor' indicate data creation.

Verdict

create_tensor_descriptor Rate-limited

create_tensor_descriptor 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Tensorus MCP, so you can run agents against it safely.

FAQ

Questions about create_tensor_descriptor

What does the create_tensor_descriptor tool do? +

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

How do I enforce a policy on create_tensor_descriptor? +

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

What risk level is create_tensor_descriptor? +

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

Can I rate-limit create_tensor_descriptor? +

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

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

create_tensor_descriptor is provided by the Tensorus MCP server (tensorus/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
