CCXT MCP Server

Instructions

Implementation Reference

• src/index.ts:163-171 (handler)

  The MCP tool handler for 'clear-cache'. Calls clearCache() from utils/cache and returns a success message.

  server.tool("clear-cache", "Clear CCXT cache", {}, async () => {
    clearCache();
    return {
      content: [{
        type: "text",
        text: "Cache cleared successfully."
      }]
    };
  });

• src/utils/cache.ts:108-133 (helper)

  Core implementation of cache clearing logic. When called without arguments (as in the tool handler), clears the entire LRU cache, resets statistics, and logs the action.

  export function clearCache(keyPattern?: string): void {
    if (keyPattern) {
      // Clear all keys matching specific pattern
      const keys = [];
      for (const key of dataCache.keys()) {
        if (typeof key === 'string' && key.includes(keyPattern)) {
          keys.push(key);
        }
      }
      
      // Delete all matching keys from cache
      keys.forEach(key => dataCache.delete(key));
      log(LogLevel.INFO, `Cleared ${keys.length} cache items matching "${keyPattern}"`);
    } else {
      // Clear entire cache
      const size = dataCache.size;
      dataCache.clear();
      log(LogLevel.INFO, `Cleared all ${size} cache items`);
    }
    
    // Update cache statistics
    cacheStats.size = dataCache.size;
    cacheStats.lastCleared = new Date().toISOString();
    cacheStats.hits = 0;
    cacheStats.misses = 0;
  }

• src/index.ts:163-171 (registration)

  Registers the 'clear-cache' tool on the MCP server with empty schema and description 'Clear CCXT cache'.

  server.tool("clear-cache", "Clear CCXT cache", {}, async () => {
    clearCache();
    return {
      content: [{
        type: "text",
        text: "Cache cleared successfully."
      }]
    };
  });
