How an agent connects · 3 tips

/api/tools/backblaze.json/tools/backblaze.mdMCP get_tool {"slug":"backblaze"}

  • Use the official MCP server: npx -y @backblaze-labs/b2-mcp (MCP 2026-07-28, stdio).
  • A human must create the account and an application key (web console > App Keys); after that B2 is reachable by API, the b2 CLI, S3 or MCP.
  • Fetch docs as Markdown with Accept: text/markdown.
