What bfs_search does on UnClick
AI agents call bfs_search to retrieve information from UnClick without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
edges | array | Yes | Array of edges |
start | string | Yes | Start node |
target | string | — | Optional target node to find path to |
directed | boolean | — | Whether the graph is directed (default true) |
Parameters from the server's own tool schema.
Why bfs_search is rated Low
This tool performs a graph traversal algorithm that retrieves information (shortest path, visit order, reachable node count) without modifying the underlying graph structure or triggering external operations. It is a pure read operation with no side effects, data modification, or resource consumption beyond computation.
From the tool's definition Breadth-first search on a graph. Finds shortest unweighted path, visit order, and reachable node count.
Attacks that exploit this kind of access
The rule that runs bfs_search 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 bfs_search, this is the rule to start with:
bfs_search is read-only, so it stays allowed. 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 bfs_search call is checked against it from then on.
Questions about bfs_search
Breadth-first search on a graph. Finds shortest unweighted path, visit order, and reachable node count. It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
bfs_search accepts 4 parameters: edges, start, target, directed. Required: edges, start. 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 bfs_search: 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.
bfs_search is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the bfs_search 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 bfs_search. 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.
bfs_search 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.
