What de_bruijn does on UnClick
AI agents invoke de_bruijn 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 |
|---|---|---|---|
k | number | Yes | Alphabet size (2-10) |
n | number | Yes | Substring length (1-10) |
Parameters from the server's own tool schema.
Why de_bruijn is rated High
This tool performs a computation/algorithm execution to generate a mathematical sequence. It doesn't read external data, write/modify state, or perform destructive/financial actions. It executes a combinatorial generation algorithm based on input parameters. Severity is low as it only produces a computed output with no side effects on external systems.
From the tool's definition Generate a de Bruijn sequence B(k,n) containing every k-ary substring of length n exactly once.

The rule that runs de_bruijn 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 de_bruijn, this is the rule to start with:
de_bruijn 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 de_bruijn call is checked against it from then on.
Questions about de_bruijn
Generate a de Bruijn sequence B(k,n) containing every k-ary substring of length n exactly once. 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.
de_bruijn accepts 2 parameters: k, n. Required: k, n. 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 de_bruijn: 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.
de_bruijn 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 de_bruijn 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 de_bruijn. 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.
de_bruijn 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.
