Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`FIBER_API_URL` Optional	Base URL of the FIBER deployment (e.g., https://api.fiber.ac or http://localhost:8000 for self-hosted).
`FIBER_API_KEY` Required, secret	Bearer token for the FIBER API. Role determines which tools work: viewer (24 read tools), operator (+write), admin (all).
`FIBER_ENABLE_WRITE` Optional	Set to 1 to expose write tools: demo trigger, NCCL ingest, RMA create. Defaults to read-only for safety.
`FIBER_MCP_TOOLS_ALLOWLIST` Optional	(v1.0.2) Optional CSV of tool names. When set, only these tools are exposed — letting operators scope autonomous agents to a minimum surface (e.g. 'fiber_health,fiber_cluster_overview,fiber_list_alerts'). Empty = all tools exposed (default).
`FIBER_HTTP_TIMEOUT` Optional	Per-request HTTP timeout in seconds. Increase if running Digital Twin Monte Carlo with iterations>1000.
