limit | integer | — | Maximum number of results to return (1-50, default 20) |

Parameters from the server's own tool schema.
Why group_search is rated Low
group_search is a read-only retrieval operation. It queries publicly available group metadata on Telegram without creating, modifying, deleting, or executing any actions. The tool only returns informational results (title, member count, preview availability). While search results could theoretically be used for monitoring or outreach preparation, the tool itself performs no side effects beyond data retrieval.
From the tool's definition Tool performs a search query that "returns matching groups with title, member count, and whether messages can be previewed." The description explicitly states it "Searches for public groups or channels" and returns metadata.
Attacks that exploit this kind of access
The rule that runs group_search safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Dialogbrain, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For group_search, this is the rule to start with:
group_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 Dialogbrain, apply this rule, and every group_search call is checked against it from then on.

group_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 group_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 group_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.
group_search is provided by the Dialogbrain MCP server (https://api.dialogbrain.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
