Install Backblaze B2 MCP Server in Continue

What you need first

• Continue, installed.
• Node.js, which gives the npx command the server starts with.
• Your own values for YOUR_B2_APPLICATION_KEY_ID,YOUR_B2_APPLICATION_KEY.

Steps

1. Open ~/.continue/config.yaml. On Windows it is %USERPROFILE%\.continue\config.yaml.
2. Add this entry. If the file already has mcpServers, add only the item from - name on.

mcpServers:
  - name: "b2-mcp"
    type: stdio
    command: "npx"
    args:
      - "-y"
      - "@backblaze-labs/[email protected]"
    env:
      "B2_APPLICATION_KEY_ID": "YOUR_B2_APPLICATION_KEY_ID"
      "B2_APPLICATION_KEY": "YOUR_B2_APPLICATION_KEY"

3. Replace YOUR_B2_APPLICATION_KEY_ID,YOUR_B2_APPLICATION_KEY with your own values.
4. Save the file and restart Continue.

Check it worked

Ask Continue: List the tools of b2-mcp.

If it does not start

spawn npx ENOENT

Node.js is not on the PATH that Continue sees. Install it, or write the full path of npx in the config.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.

Nothing changes after a restart

The file is not valid YAML any more. Check that the entry is indented like the lines around it.
