Part of the AWS Pricing MCP Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call get_pricing_service_codes to retrieve information from AWS Pricing MCP Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_pricing_service_codes only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Get AWS service codes available in the Price List API. **PURPOSE:** Discover which AWS services have pricing information available in the AWS Price List API. **PARAMETERS:** - filter (optional): Case-insensitive regex pattern to filter service codes (e.g., "bedrock" matches "AmazonBedrock", "AmazonBedrockService") **WORKFLOW:** This is the starting point for any pricing query. Use this first to find the correct service code. **RETURNS:** List of service codes (e.g., 'AmazonEC2', 'AmazonS3', 'AWSLambda') that can be used with other pricing tools. **NEXT STEPS:** - Use get_pricing_service_attributes() to see what filters are available for a service - Use get_pricing() to get actual pricing data for a service **NOTE:** Service codes may differ from AWS console names (e.g., 'AmazonES' for OpenSearch, 'AWSLambda' for Lambda).. It is categorised as a Read tool in the AWS Pricing MCP Server MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for get_pricing_service_codes. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the AWS Pricing MCP Server MCP server.
get_pricing_service_codes 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_pricing_service_codes 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.
Set action: deny in the Intercept policy for get_pricing_service_codes. 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_pricing_service_codes is provided by the AWS Pricing MCP Server MCP server (awslabs.aws-pricing-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
