Get a single CDV segment by its numeric ID.
AI agents call get_segment 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 data (a segment) based on an identifier. It has no side effects and does not create, modify, delete, or execute anything. It fits the Read category definition: 'retrieves or queries data; no side effects (search, list, get, fetch).' The severity is low because misuse would only expose existing data without enabling destructive or financial harm.
From the tool's definition Tool name is 'get_segment' and description states 'Get a single CDV segment by its numeric ID' — this is a retrieval operation with no modification, deletion, or execution of code.
Attacks that exploit this kind of access
Get a single CDV segment 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_segment: 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_segment 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_segment 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_segment. 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_segment 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.
