Get a single CDV data connection by its numeric ID.
AI agents call get_connection to retrieve information from Cloudera Data Visualization 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 metadata about an existing data connection. It performs a query operation (get) that does not modify, execute, delete, or create resources. The action is read-only and has minimal blast radius if misused by an AI agent—at worst, it could expose connection details, but cannot alter infrastructure or trigger operations.
From the tool's definition Tool name 'get_connection' and description 'Get a single CDV data connection by its numeric ID' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Get a single CDV data connection by its numeric ID. It is categorised as a Read tool in the Cloudera Data Visualization MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Cloudera Data Visualization MCP Server MCP server in PolicyLayer and add a rule for get_connection: 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 Cloudera Data Visualization MCP Server. Nothing to install.
get_connection 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 get_connection 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 get_connection. 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.
get_connection is provided by the Cloudera Data Visualization MCP Server MCP server (kevintalbert/cdv-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
