List all values in a LevelDB sublevel (e.g. !games! to list all games)
AI agents call hydra_leveldb_values 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.
The 'List all values' function clearly performs data querying without creating, modifying, or deleting content. However, severity is medium rather than low because LevelDB is Hydra's core data store, and enumerating all values in the database could expose sensitive information (game libraries, user preferences, auth tokens, download history) to an AI agent or attacker.
From the tool's definition Tool name is 'hydra_leveldb_values' and description states 'List all values in a LevelDB sublevel' — this is a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List all values in a LevelDB sublevel (e.g. !games! to list all games). It is categorised as a Read tool in the Hydra Bridge MCP Server, which means it retrieves data without modifying state.
Register the Hydra Bridge MCP server in PolicyLayer and add a rule for hydra_leveldb_values: 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_leveldb_values 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_leveldb_values 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_leveldb_values. 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.
hydra_leveldb_values is provided by the Hydra Bridge MCP server (kleirrampage45/hydra-bridge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
