Get all Spark applications/sessions for a specific Spark job definition
AI agents call get-spark-job-definition-applications to retrieve information from Fabric-Analytics-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries existing Spark job information without creating, modifying, deleting, or executing operations. It merely retrieves metadata about applications/sessions associated with a Spark job definition. The blast radius is low—an AI agent misusing this retrieves data only, with no side effects or resource consumption.
From the tool's definition The tool retrieves Spark applications/sessions for a job definition ('Get all' indicates retrieval, not modification). The verb 'get' and lack of descriptors like 'create', 'delete', 'execute', or 'modify' confirm read-only access.
Documented attack patterns abuse exactly the kind of access get-spark-job-definition-applications gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Fabric-Analytics-MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get-spark-job-definition-applications:
{
"version": "1",
"default": "deny",
"tools": {
"get-spark-job-definition-applications": {}
}
}get-spark-job-definition-applications is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get all Spark applications/sessions for a specific Spark job definition. It is categorised as a Read tool in the Fabric-Analytics-MCP MCP Server, which means it retrieves data without modifying state.
Register the Fabric-Analytics- MCP server in PolicyLayer and add a rule for get-spark-job-definition-applications: 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 Fabric-Analytics-MCP. Nothing to install.
get-spark-job-definition-applications 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-spark-job-definition-applications 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-spark-job-definition-applications. 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-spark-job-definition-applications is provided by the Fabric-Analytics- MCP server (santhoshravindran7/fabric-analytics-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
