MCP Tool Response Caching Layer: Claude Code Prompt

Create a caching middleware for MCP tools that stores deterministic results and invalidates on write operations

Write the TypeScript response caching middleware for the MCP server in [YOUR_PROJECT].

Requirements:
**Cache store**: In-memory Map by default. Use Redis if REDIS_URL is set.
**Cache key**: MD5 hash of tool name plus JS
TLDR

Response caching middleware for MCP tools. Caches results of deterministic tools (like list_tables and describe) with configurable TTLs and automatically invalidates cache on write operations.

How to use

  1. 1

    Replace [YOUR_PROJECT] with the specific project name to ensure the generated TypeScript middleware is tailored to your application's context.

  2. 2

    Follow up by defining CACHE_TTLS in your environment variables to control the caching duration for each tool, ensuring optimal performance for your MCP server.

  3. 3

    Try implementing the bypass flag force_refresh boolean in your requests to test cache behavior and ensure that your middleware functions as intended during development.
