Create / sign in to your Byul account
- Go to https://byul.ai and sign up or log in. (docs.byul.ai)
Open the Byul API Dashboard and locate your API key
- In the dashboard (Account / API Dashboard), your API key is generated and displayed. Copy it to your clipboard. (docs.byul.ai)
Confirm the API key format
- The key begins with the byul_ / byul_v2 prefix (for example: byul_xxxxxxxxx or byul_v2_xxxxx). Keep this exact string. (docs.byul.ai)
Open the FastMCP connection interface in your client
- Click the "Install Now" button you already have to add environment variables via the FastMCP connection UI.
Add the environment variable
- In the FastMCP env entry form:
- Key / Name: BYUL_API_KEY
- Value: paste the API key you copied from the Byul dashboard
- Save the entry in the FastMCP connection interface.
- In the FastMCP env entry form:
Restart / (re)launch the MCP provider if required
- Restart the MCP server or your LLM client so the new environment variable is picked up (the MCP server reads env vars at launch).
Verify the server starts and the key works
- Launch the MCP (or run a quick tool call). If the key is missing you would see an error like "Missing BYUL_API_KEY environment variable" — if no error appears, try a simple news_fetch to confirm responses. (docs.byul.ai)
Follow security best practices
- Do not hardcode the key in source code or client-side code; store it as BYUL_API_KEY in the FastMCP env settings. Rotate keys periodically and restrict access as needed. (docs.byul.ai)
