Implementation Reference

• src/index.ts:1268-1315 (handler)

  Handler function for the 'list_projects' tool. Validates input directory, calls findGodotProjects helper, and returns JSON list of projects.

  private async handleListProjects(args: any) {
    // Normalize parameters to camelCase
    args = this.normalizeParameters(args);
    
    if (!args.directory) {
      return this.createErrorResponse(
        'Directory is required',
        ['Provide a valid directory path to search for Godot projects']
      );
    }
  
    if (!this.validatePath(args.directory)) {
      return this.createErrorResponse(
        'Invalid directory path',
        ['Provide a valid path without ".." or other potentially unsafe characters']
      );
    }
  
    try {
      this.logDebug(`Listing Godot projects in directory: ${args.directory}`);
      if (!existsSync(args.directory)) {
        return this.createErrorResponse(
          `Directory does not exist: ${args.directory}`,
          ['Provide a valid directory path that exists on the system']
        );
      }
  
      const recursive = args.recursive === true;
      const projects = this.findGodotProjects(args.directory, recursive);
  
      return {
        content: [
          {
            type: 'text',
            text: JSON.stringify(projects, null, 2),
          },
        ],
      };
    } catch (error: any) {
      return this.createErrorResponse(
        `Failed to list projects: ${error?.message || 'Unknown error'}`,
        [
          'Ensure the directory exists and is accessible',
          'Check if you have permission to read the directory',
        ]
      );
    }
  }

• src/index.ts:729-744 (schema)

  Input schema and registration for the 'list_projects' tool in the ListTools response.

  name: 'list_projects',
  description: 'List Godot projects in a directory',
  inputSchema: {
    type: 'object',
    properties: {
      directory: {
        type: 'string',
        description: 'Directory to search for Godot projects',
      },
      recursive: {
        type: 'boolean',
        description: 'Whether to search recursively (default: false)',
      },
    },
    required: ['directory'],
  },

• src/index.ts:602-660 (helper)

  Core helper function that implements the logic to find Godot projects by searching for 'project.godot' files in directories, supporting recursive search.

  private findGodotProjects(directory: string, recursive: boolean): Array<{ path: string; name: string }> {
    const projects: Array<{ path: string; name: string }> = [];
  
    try {
      // Check if the directory itself is a Godot project
      const projectFile = join(directory, 'project.godot');
      if (existsSync(projectFile)) {
        projects.push({
          path: directory,
          name: basename(directory),
        });
      }
  
      // If not recursive, only check immediate subdirectories
      if (!recursive) {
        const entries = readdirSync(directory, { withFileTypes: true });
        for (const entry of entries) {
          if (entry.isDirectory()) {
            const subdir = join(directory, entry.name);
            const projectFile = join(subdir, 'project.godot');
            if (existsSync(projectFile)) {
              projects.push({
                path: subdir,
                name: entry.name,
              });
            }
          }
        }
      } else {
        // Recursive search
        const entries = readdirSync(directory, { withFileTypes: true });
        for (const entry of entries) {
          if (entry.isDirectory()) {
            const subdir = join(directory, entry.name);
            // Skip hidden directories
            if (entry.name.startsWith('.')) {
              continue;
            }
            // Check if this directory is a Godot project
            const projectFile = join(subdir, 'project.godot');
            if (existsSync(projectFile)) {
              projects.push({
                path: subdir,
                name: entry.name,
              });
            } else {
              // Recursively search this directory
              const subProjects = this.findGodotProjects(subdir, true);
              projects.push(...subProjects);
            }
          }
        }
      }
    } catch (error) {
      this.logDebug(`Error searching directory ${directory}: ${error}`);
    }
  
    return projects;
  }

• src/index.ts:944-945 (registration)

  Dispatch/registration in the CallToolRequestSchema switch statement that routes calls to the list_projects handler.

  case 'list_projects':
    return await this.handleListProjects(request.params.arguments);
