What gts_search does on Crow
AI agents call gts_search to retrieve information from Crow without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why gts_search is rated Low
This tool performs read-only queries across the fediverse to retrieve account, hashtag, and status information. There are no side effects, data modification, code execution, or irreversible operations. The rate limit (60/hour) is standard for public search APIs. The primary risk is information disclosure or enumeration, which is low severity given the data queried is typically public on federated social platforms.
From the tool's definition Tool description explicitly states 'Search accounts / hashtags / statuses' and mentions 'Remote queries resolve via WebFinger.' Search operations retrieve data without modification. Rate-limiting indicates the operation is query-based, not mutative.
Attacks that exploit this kind of access
The rule that runs gts_search safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Crow, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For gts_search, this is the rule to start with:
gts_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 Crow, apply this rule, and every gts_search call is checked against it from then on.

gts_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 gts_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 gts_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.
gts_search is provided by the Crow MCP server (kh0pper/crow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
