  "summary": "Backblaze B2 is automatable today through the B2 Native API. This record is B2 Cloud Storage, not Backblaze Computer Backup. GET https://api.backblazeb2.com/b2api/v4/b2_authorize_account returns an authorization token and an apiUrl such as https://api001.backblazeb2.com for later calls. The request uses HTTP Basic. The username is the application key ID and the password is the application key, joined as applicationKeyId:applicationKey and Base64-encoded. Master and standard application keys both work. Multi-bucket keys require this v4 authorize call. The application key guide says the returned authorization token expires after 24 hours and is limited to that key's capabilities. Standard keys can be limited to buckets, a file prefix, read or write, and a duration. b2_create_key, b2_delete_key, and b2_list_keys manage keys. The cloud-storage page says you can start building with no credit card, and it documents free egress up to three times average monthly stored data and free API transactions. B2 Overdrive is a paid high-throughput tier. Backblaze Labs publishes github.com/backblaze-labs/b2-mcp and calls it the official B2 MCP server, with native B2, S3-compatible, and report tools. The Backblaze Labs organization says its projects are exploratory and not production-supported. Destructive actions are gated in the server. A general B2 CLI, a language SDK, and connector catalogs were not opened. Computer-use viability is unassessed. The Native API scores 8 and is the best path. The Labs MCP server scores 5.\n"
