Analyze D1 database schema structure, tables, columns, indexes, and relationships with optional sample data
AI agents call analyze_database_schema to retrieve information from Semantic D1 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 analyzes existing database schema information. While it may include optional sample data retrieval, it performs no writes, deletes, executions, or financial operations. The core function is inspection and metadata querying, which falls squarely in the Read category. Even with sample data access, this remains non-destructive information gathering with minimal blast radius if misused.
From the tool's definition Tool performs 'analyze' and 'introspection' of schema 'structure, tables, columns, indexes, and relationships with optional sample data'.
Attacks that exploit this kind of access
Analyze D1 database schema structure, tables, columns, indexes, and relationships with optional sample data. It is categorised as a Read tool in the Semantic D1 MCP MCP Server, which means it retrieves data without modifying state.
Register the Semantic D1 MCP server in PolicyLayer and add a rule for analyze_database_schema: 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 Semantic D1 MCP. Nothing to install.
analyze_database_schema 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_database_schema 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_database_schema. 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_database_schema is provided by the Semantic D1 MCP server (semanticintent/semantic-d1-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
