Implementation Reference

• src/mcp-server.ts:395-418 (handler)

  The handler function that executes the reinitialize_indexer tool logic. It optionally updates the working directory and config, then calls the typeIndexer.initialize() method, returning a success message.

  private async handleReinitializeIndexer(workingDir?: string) {
    try {
      if (workingDir) {
        this.config = WorkspaceDetector.detectProjectConfig(workingDir);
        this.typeIndexer = new TypeIndexer(this.config);
      }
      
      await this.typeIndexer.initialize();
      
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify({
              message: "Type indexer reinitialized successfully",
              config: this.config
            }, null, 2)
          }
        ]
      };
    } catch (error) {
      throw new Error(`Failed to reinitialize indexer: ${error instanceof Error ? error.message : String(error)}`);
    }
  }

• src/mcp-server.ts:189-202 (registration)

  Registration of the reinitialize_indexer tool in the ListTools response, including name, description, and input schema definition.

  {
    name: "reinitialize_indexer",
    description: "Reinitialize the type indexer (useful after package installations)",
    inputSchema: {
      type: "object",
      properties: {
        workingDir: {
          type: "string",
          description: "Optional working directory to reinitialize from"
        }
      },
      additionalProperties: false
    }
  }

• src/mcp-server.ts:252-255 (registration)

  The switch case in CallToolRequest handler that routes the reinitialize_indexer tool call to the handleReinitializeIndexer method after argument validation.

  case "reinitialize_indexer": {
    const reinitArgs = this.validateArgs<ToolArguments["reinitialize_indexer"]>(args);
    return await this.handleReinitializeIndexer(reinitArgs.workingDir);
  }

• src/mcp-server.ts:26-26 (schema)

  TypeScript interface definition for the tool arguments used in validateArgs for type safety.

  reinitialize_indexer: { workingDir?: string };
