What matrix_rank does on UnClick
AI agents invoke matrix_rank to trigger actions in UnClick. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
| Parameter | Type | Required | Description |
|---|---|---|---|
matrix | array | Yes | 2D number array (max 100x100) |
Parameters from the server's own tool schema.
Why matrix_rank is rated High
This tool executes a mathematical computation (Gaussian elimination) on provided input data. It has no side effects on external systems, data stores, or finances. Severity is low because misuse only results in incorrect mathematical output, not system compromise or data loss.
From the tool's definition 'Compute the rank of a matrix using Gaussian elimination with partial pivoting' — runs a numerical algorithm/computation
Attacks that exploit this kind of access
The rule that runs matrix_rank safely
PolicyLayer is an MCP gateway: it sits between your AI agents and UnClick, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For matrix_rank, this is the rule to start with:
matrix_rank stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect UnClick, apply this rule, and every matrix_rank call is checked against it from then on.
Questions about matrix_rank
Compute the rank of a matrix using Gaussian elimination with partial pivoting. It is categorised as a Execute tool in the UnClick MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
matrix_rank accepts 1 parameter: matrix. Required: matrix. The full parameter table on this page comes from the server's own tool schema.
Register the UnClick MCP server in PolicyLayer and add a rule for matrix_rank: 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 UnClick. Nothing to install.
matrix_rank is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the matrix_rank 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.
Set action: deny in the PolicyLayer policy for matrix_rank. 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.
matrix_rank is provided by the UnClick MCP server (@unclick/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
