Implementation Reference
- src/lib/firebase/storageClient.ts:10-51 (handler)Core handler function implementing the storage_list_files tool logic: lists files and directories in Firebase Storage bucket with pagination, generates signed URLs for files and console links for directories, returns JSON-formatted result.
export async function listDirectoryFiles(path?: string, pageSize: number = 10, pageToken?: string): Promise<{ content: { type: string , text: string }[] }> { const prefix = path ? (path === '' ? '' : (path.endsWith('/') ? path : `${path}/`)) : ''; const [files, , apiResponse] = await admin.storage().bucket().getFiles({ prefix, delimiter: '/', maxResults: pageSize, pageToken }); const nextPageToken = apiResponse.nextPageToken as string || undefined; const fileNames = await Promise.all(files.map(async (file) => { const [signedUrl] = await file.getSignedUrl({ action: 'read', expires: Date.now() + 1000 * 60 * 60 // 1 hour }); return { type: "file", name: file.name, downloadURL: signedUrl }; })); const projectId = getProjectId(); const bucketName = admin.storage().bucket().name; const directoryNames = (apiResponse.prefixes || []).map((prefix:string) => { //const encodedPrefix = encodeURIComponent(prefix).replace(/'/g, '%27').replace(/%20/g, '+'); const tmpPrefix = prefix.replace(/\/$/, ''); const encodedPrefix = `~2F${tmpPrefix.replace(/\//g, '~2F')}`; const consoleUrl = `https://console.firebase.google.com/project/${projectId}/storage/${bucketName}/files/${encodedPrefix}`; return { type: "directory", name: prefix, url: consoleUrl }; }); const result = { nextPageToken: nextPageToken, files: [...fileNames, ...directoryNames], hasMore: nextPageToken !== undefined }; return { content:[ { type: "text", text: JSON.stringify(result,null,2) } ] } } - src/index.ts:196-208 (schema)Input schema definition for the storage_list_files tool, specifying optional directoryPath parameter.
