MCP Client Configuration Server

Instructions

Implementation Reference

• src/index.ts:239-251 (handler)

  Handler implementation for the 'get_configuration_path' tool. Validates the client parameter and returns the computed configuration path using the getConfigPath helper.

  case 'get_configuration_path': {
    const client = validateClient(args.client);
    const configPath = getConfigPath(client);
    
    return {
      content: [
        {
          type: 'text',
          text: configPath,
        },
      ],
    };
  }

• src/index.ts:127-140 (registration)

  Tool registration in the ListTools response, including name, description, and input schema.

  {
    name: 'get_configuration_path',
    description: 'Get the path to the configuration file for a specific client',
    inputSchema: {
      type: 'object',
      properties: {
        client: {
          type: 'string',
          description: 'Client name (cline, roo_code, windsurf, claude)',
        },
      },
      required: ['client'],
    },
  },

• src/index.ts:18-53 (helper)

  Core helper function that computes the configuration file path based on the client type and operating system platform (Windows/macOS).

  const getConfigPath = (client: ClientType): string => {
    const platform = os.platform();
    const homeDir = os.homedir();
    
    if (platform === 'win32') {
      // Windows paths
      switch (client) {
        case 'cline':
          return path.join(homeDir, 'AppData', 'Roaming', 'Code', 'User', 'globalStorage', 'saoudrizwan.claude-dev', 'settings', 'cline_mcp_settings.json');
        case 'roo_code':
          return path.join(homeDir, 'AppData', 'Roaming', 'Code', 'User', 'globalStorage', 'rooveterinaryinc.roo-cline', 'settings', 'cline_mcp_settings.json');
        case 'windsurf':
          return path.join(homeDir, 'AppData', 'Roaming', 'WindSurf', 'mcp_settings.json');
        case 'claude':
          return path.join(homeDir, 'AppData', 'Roaming', 'Claude', 'claude_desktop_config.json');
        default:
          throw new McpError(ErrorCode.InvalidParams, `Unsupported client: ${client}`);
      }
    } else if (platform === 'darwin') {
      // macOS paths
      switch (client) {
        case 'cline':
          return path.join(homeDir, 'Library', 'Application Support', 'Code', 'User', 'globalStorage', 'saoudrizwan.claude-dev', 'settings', 'cline_mcp_settings.json');
        case 'roo_code':
          return path.join(homeDir, 'Library', 'Application Support', 'Code', 'User', 'globalStorage', 'rooveterinaryinc.roo-cline', 'settings', 'cline_mcp_settings.json');
        case 'windsurf':
          return path.join(homeDir, '.codeium', 'windsurf', 'mcp_config.json');
        case 'claude':
          return path.join(homeDir, 'Library', 'Application Support', 'Claude', 'claude_desktop_config.json');
        default:
          throw new McpError(ErrorCode.InvalidParams, `Unsupported client: ${client}`);
      }
    } else {
      throw new McpError(ErrorCode.InternalError, `Unsupported platform: ${platform}`);
    }
  };

• src/index.ts:56-67 (helper)

  Helper function to validate the client parameter against supported types.

  const validateClient = (client: unknown): ClientType => {
    if (typeof client !== 'string') {
      throw new McpError(ErrorCode.InvalidParams, 'Client must be a string');
    }
    
    const validClients: ClientType[] = ['cline', 'roo_code', 'windsurf', 'claude'];
    if (!validClients.includes(client as ClientType)) {
      throw new McpError(ErrorCode.InvalidParams, `Invalid client: ${client}. Must be one of: ${validClients.join(', ')}`);
    }
    
    return client as ClientType;
  };

• src/index.ts:130-139 (schema)

  Input schema definition for the get_configuration_path tool, specifying the required 'client' string parameter.

  inputSchema: {
    type: 'object',
    properties: {
      client: {
        type: 'string',
        description: 'Client name (cline, roo_code, windsurf, claude)',
      },
    },
    required: ['client'],
  },
