List all databases/dashboards in the organization. Returns dashboard and view UUIDs that can be used with get_database_data. Probes known entity types (spaces, clients) plus any custom entities you specify.
AI agents call list_databases to retrieve information from Fusebase MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates databases/dashboards—a read-only operation with no side effects. It gathers organizational metadata (dashboard/view UUIDs) to enable downstream queries. While enumeration could support reconnaissance in a malicious agent scenario, the severity remains low because it only returns existing data structures without modifying, destroying, or committing resources.
From the tool's definition Tool performs list/query operations ('List all databases/dashboards') and returns identifiers for use with other tools. No data modification, deletion, or external execution described.

List all databases/dashboards in the organization. Returns dashboard and view UUIDs that can be used with get_database_data. Probes known entity types (spaces, clients) plus any custom entities you specify. It is categorised as a Read tool in the Fusebase MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Fusebase MCP Server MCP server in PolicyLayer and add a rule for list_databases: 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 Fusebase MCP Server. Nothing to install.
list_databases 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 list_databases 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 list_databases. 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.
list_databases is provided by the Fusebase MCP Server MCP server (ryan-haver/fusebase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_databases is one line of Fusebase MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
