Use Backblaze B2 from Claude Code, Cursor or Codex

Connect Backblaze B2 in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Backblaze B2 operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs
