// WHEN AI AGENTS USE THIS TOOL

AI agents invoke source_db_analyzer to trigger processes or run actions in AWS DynamoDB MCP Server. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

// WHY ENFORCE A POLICY ON SOURCE_DB_ANALYZER

source_db_analyzer can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.

// RECOMMENDED POLICY

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

What does the source_db_analyzer tool do? +

Analyzes source database to extract schema and access patterns for DynamoDB modeling. WHEN TO USE: Call this tool when the user selects "Existing Database Analysis" option after invoking the `dynamodb_data_modeling` tool. This extracts schema and query patterns from an existing relational database to accelerate DynamoDB data model design. IMPORTANT: Always ask the user which execution mode they prefer before calling this tool. Execution Modes: - self_service: Generates SQL queries for user to run manually, then parses their results. - managed (MySQL only): Database connection via RDS Data API or hostname. Supported Databases: MySQL, PostgreSQL, SQL Server, Oracle Output: Generates analysis files (schema structure, access patterns, relationships) in Markdown format. These files feed into the DynamoDB data modeling workflow to inform table design, GSI selection, and access pattern mapping. Returns: Analysis summary with file locations and next steps.. It is categorised as a Execute tool in the AWS DynamoDB MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on source_db_analyzer? +

Add a rule in your Intercept YAML policy under the tools section for source_db_analyzer. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the AWS DynamoDB MCP Server MCP server.

What risk level is source_db_analyzer? +

source_db_analyzer is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit source_db_analyzer? +

Yes. Add a rate_limit block to the source_db_analyzer rule in your Intercept 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.

How do I block source_db_analyzer completely? +

Set action: deny in the Intercept policy for source_db_analyzer. 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.

What MCP server provides source_db_analyzer? +

source_db_analyzer is provided by the AWS DynamoDB MCP Server MCP server (awslabs.dynamodb-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
