VyMCP

MCP server for VyOS routers, powered by VyManager.

VyMCP lets AI agents read and manage VyOS routers through the VyManager API — inheriting VyManager's authentication, RBAC, audit, and commit-confirm safety. It never talks to routers directly.

Status: alpha. Runs local (stdio) or as a shared hosted server (http); interfaces may change.

Install

pipx install git+https://github.com/Community-VyProjects/VyMCP   # provides `vymcp`

Or pip install . from a clone, or run the Docker image ghcr.io/community-vyprojects/vymcp (attached, with -i).

Related MCP server: MikroMCP

Configure

Set environment variables (see .env.example):

VYMANAGER_VERIFY_SSL (default true) and VYMANAGER_TIMEOUT (default 30) are optional.

Hosted deployment (shared server)

Run one VyMCP that many engineers connect to over HTTP, each authenticating with their own VyManager token per request:

docker compose up -d          # see docker-compose.yml

Set VYMANAGER_BASE_URL and VYMCP_PUBLIC_URL in the compose file. Engineers point their MCP client at https://<vymcp>/mcp with Authorization: Bearer vym_…. Terminate TLS at a reverse proxy and run a single replica (the pending-change store is in-memory).

Tools

• Read (always): list_instances, list_features, get_capabilities, get_config.

• Write (only when VYMANAGER_ENABLE_WRITES=true): describe_feature_operations + propose_operations cover ~86 features; apply_change / confirm_change / discard_changes / get_pending_changes drive the rollout.

Writes are safe by design: off by default, capped to the token's scope, and gated by a propose → apply flow. apply_change requires explicit confirmation and rides VyManager's commit-confirm auto-rollback (a lockout safety net) — it never auto-confirms.
