MCP Environment & Installation Manager

Implementation Reference

• src/tools/watcher-tools.ts:19-81 (registration)

  Registers the configure-watcher tool with MCP server, including schema and inline handler function.

  server.tool(
    "configure-watcher",
    {
      watchClaude: z.boolean().optional().describe("Whether to watch Claude for Desktop config"),
      watchCursor: z.boolean().optional().describe("Whether to watch Cursor config"),
      claudeConfigPath: z.string().optional().describe("Path to Claude for Desktop config file"),
      cursorConfigPath: z.string().optional().describe("Path to Cursor config file")
    },
    async ({ watchClaude, watchCursor, claudeConfigPath, cursorConfigPath }, extra) => {
      const config = configService.getInstallationConfig();
      
      const updates = {
        watchers: {
          ...config.watchers
        }
      };
      
      if (watchClaude !== undefined) {
        updates.watchers.claude = {
          ...config.watchers.claude,
          enabled: watchClaude
        };
      }
      
      if (watchCursor !== undefined) {
        updates.watchers.cursor = {
          ...config.watchers.cursor,
          enabled: watchCursor
        };
      }
      
      if (claudeConfigPath !== undefined) {
        updates.watchers.claude = {
          ...config.watchers.claude,
          configPath: claudeConfigPath
        };
      }
      
      if (cursorConfigPath !== undefined) {
        updates.watchers.cursor = {
          ...config.watchers.cursor,
          configPath: cursorConfigPath
        };
      }
      
      const updatedConfig = await configService.updateInstallationConfig(updates);
      
      // Reinitialize watchers with new config
      await watcherService.initializeWatchers();

            }, null, 2)
          }
        ]
      };
    }
  );

• src/tools/watcher-tools.ts:27-80 (handler)

  The main handler logic for the configure-watcher tool: updates watcher configurations in installation config and reinitializes watchers via services.

  async ({ watchClaude, watchCursor, claudeConfigPath, cursorConfigPath }, extra) => {
    const config = configService.getInstallationConfig();
    
    const updates = {
      watchers: {
        ...config.watchers
      }
    };
    
    if (watchClaude !== undefined) {
      updates.watchers.claude = {
        ...config.watchers.claude,
        enabled: watchClaude
      };
    }
    
    if (watchCursor !== undefined) {
      updates.watchers.cursor = {
        ...config.watchers.cursor,
        enabled: watchCursor
      };
    }
    
    if (claudeConfigPath !== undefined) {
      updates.watchers.claude = {
        ...config.watchers.claude,
        configPath: claudeConfigPath
      };
    }
    
    if (cursorConfigPath !== undefined) {
      updates.watchers.cursor = {
        ...config.watchers.cursor,
        configPath: cursorConfigPath
      };
    }
    
    const updatedConfig = await configService.updateInstallationConfig(updates);
    
    // Reinitialize watchers with new config
    await watcherService.initializeWatchers();
    
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify({
            success: true,
            watchers: updatedConfig.watchers
          }, null, 2)
        }
      ]
    };
  }

• src/tools/watcher-tools.ts:21-26 (schema)

  Zod schema defining optional boolean flags for enabling watchers and optional string paths for config files.

  {
    watchClaude: z.boolean().optional().describe("Whether to watch Claude for Desktop config"),
    watchCursor: z.boolean().optional().describe("Whether to watch Cursor config"),
    claudeConfigPath: z.string().optional().describe("Path to Claude for Desktop config file"),
    cursorConfigPath: z.string().optional().describe("Path to Cursor config file")
  },
