listDatabases
AI agents call listDatabases to retrieve information from ArangoDB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool lists databases, which is a read-only query operation that retrieves metadata about available databases. No data is created, modified, deleted, or executed. The empty description is compensated by the clear semantics of the tool name ('list') and the server's documented capability to 'list databases and collections.' Severity is low because database enumeration alone poses minimal risk unless used to…
From the tool's definition Tool name 'listDatabases' and server purpose of 'enabling interaction with ArangoDB databases, allowing users to perform queries, list databases and collections through natural language' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
listDatabases. It is categorised as a Read tool in the ArangoDB MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ArangoDB MCP Server MCP server in PolicyLayer and add a rule for listDatabases: 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 ArangoDB MCP Server. Nothing to install.
listDatabases 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 listDatabases 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 listDatabases. 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.
listDatabases is provided by the ArangoDB MCP Server MCP server (lucas-deangelis/arango-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
