Get Hydra user preferences (download paths, Proton settings, etc.)
AI agents call hydra_get_preferences to retrieve information from Hydra Bridge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves user preference settings without side effects. No data is modified, deleted, or executed. It is a pure read operation that queries existing preference state. The blast radius if misused is minimal—an AI agent could learn user configuration but cannot change behavior or access sensitive operations through this tool alone.
From the tool's definition Tool name 'hydra_get_preferences' and description 'Get Hydra user preferences' explicitly indicate a retrieval operation with no modification capability.

Register the Hydra Bridge MCP server in PolicyLayer and add a rule for hydra_get_preferences: 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 Hydra Bridge. Nothing to install.
hydra_get_preferences 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 hydra_get_preferences 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 hydra_get_preferences. 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.
