Implementation Reference

  • The main handler function that executes the logic for the 'disconnect_redis' MCP tool. It checks if a Redis connection exists, calls disconnect on the service if so, clears the service references, and returns a standardized MCP response with the result.
    private async handleDisconnectRedis() {
      if (!this.redisService) {
        return {
          content: [
            {
              type: 'text',
              text: JSON.stringify({ success: false, error: 'Not connected to Redis' }, null, 2)
            }
          ]
        };
      }
      
      const result = await this.redisService.disconnect();
      this.redisService = null;
      this.backupService = null;
      
      return {
        content: [
          {
            type: 'text',
            text: JSON.stringify(result, null, 2)
          }
        ]
      };
    }
  • Tool registration in the MCP server's tools list. Defines the tool name, description, and input schema (empty object, no parameters required). This is passed to server.setTools().
    {
      name: 'disconnect_redis',
      description: '断开与 Redis 服务器的连接',
      inputSchema: {
        type: 'object',
        properties: {}
      }
    },
  • Dispatch registration in the switch statement of the CallToolRequestHandler. Routes calls to the 'disconnect_redis' tool to its handler method.
    case 'disconnect_redis':
      return await this.handleDisconnectRedis();
  • Input schema for the 'disconnect_redis' tool, defining an empty object (no input parameters required). Part of the tool registration.
    inputSchema: {
      type: 'object',
      properties: {}
    }
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It states the action ('断开连接') but doesn't disclose behavioral traits such as whether this closes all connections, requires specific permissions, has side effects on other operations, or what happens if no connection exists. This is a significant gap for a tool that likely involves network/state changes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence in Chinese ('断开与 Redis 服务器的连接'), which directly conveys the purpose without any waste. It's appropriately sized and front-loaded for a simple tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity of disconnecting from a server (likely involving state changes), no annotations, no output schema, and 0 parameters, the description is incomplete. It lacks details on behavior, return values, or error conditions, making it inadequate for safe and effective use by an AI agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0 parameters with 100% coverage, so no parameter documentation is needed. The description doesn't add parameter details, which is appropriate here, but it also doesn't compensate for any gaps since there are none. Baseline is 4 for zero parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('断开连接' meaning 'disconnect') and the target resource ('Redis 服务器' meaning 'Redis server'), providing a specific verb+resource combination. However, it doesn't differentiate from sibling tools like 'connect_redis' beyond the obvious opposite action, missing explicit comparison.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives or prerequisites. While it's implied to be used after connecting to Redis (given the sibling 'connect_redis'), there's no explicit mention of context, exclusions, or dependencies.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
