AI agents call analyze_source_structure to retrieve information from Insight Digger MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and inspects data source structure (schema, fields, metadata) without creating, modifying, or deleting anything. It is a Read operation. Severity is medium rather than low because: (1) it may expose sensitive schema details about enterprise data sources that could inform further attacks, and (2) an AI agent with repeated access could map an organization's entire data architecture.
From the tool's definition Fetches and analyzes the structure of a given data source; described as a key step for discovering data source schema/metadata without modification

Fetches and analyzes the structure of a given data source. This is a key step after selecting a source. 🔄 Auto-Cached: apiUrl and jwtToken are automatically provided from authentication. Only provide the. It is categorised as a Read tool in the Insight Digger MCP MCP Server, which means it retrieves data without modifying state.
Register the Insight Digger MCP server in PolicyLayer and add a rule for analyze_source_structure: 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 Insight Digger MCP. Nothing to install.
analyze_source_structure 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 analyze_source_structure 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 analyze_source_structure. 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.
analyze_source_structure is provided by the Insight Digger MCP server (sandsiv/data_narrator_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
