DevNet sandbox

Cisco DevNet provides a public always-on SD-WAN sandbox you can point this MCP at without needing your own vManage.

Connection details

Field Value
Host sandbox-sdwan-2.cisco.com
Port 443
Username devnetuser
Password RG!_Yw919_83
TLS verify false (self-signed)
Auth use_jwt: true (modern JWT endpoint) — fall back to false if Cisco rolls the sandbox back to an older release

Reservation page: https://developer.cisco.com/sdwan/sandbox/ — check the listed version there and pick the matching folder under specs/.

Fastest path: no clone

active_version: "20.18" is the built-in default, so once you set the host and credentials a one-liner with uvx connects straight away (the host is also the default, but it's shown explicitly here so the example is self-contained):

VMANAGE_HOST=sandbox-sdwan-2.cisco.com \
VMANAGE_USERNAME=devnetuser VMANAGE_PASSWORD='RG!_Yw919_83' \
  VMANAGE_VERIFY_SSL=false uvx catalyst-sdwan-super-mcp

VMANAGE_VERIFY_SSL=false is required here because the sandbox serves a self-signed certificate (the table above) — the bundled sdwan-mcp.yaml sets it for the source-checkout flow, but a uvx run from an arbitrary directory has no config file, so pass it on the command line.

From a source checkout

The repo's sdwan-mcp.yaml ships pointing at this host with active_version: "20.18". Just set credentials in .env:

cp .env.example .env
cat >> .env <<'EOF'
VMANAGE_USERNAME=devnetuser
VMANAGE_PASSWORD=RG!_Yw919_83
EOF

Then:

uv run sdwan-mcp

If the sandbox version differs from the default, override at the command line (drop the uv run prefix when using an installed CLI or uvx catalyst-sdwan-super-mcp):

uv run sdwan-mcp --version 20.15

Heads-up

  • The sandbox warms up on demand. The first request may take 30–60 seconds and return 503 while the lab spins up. Retry.
  • It's shared. Treat it as read-mostly — don't break it for the next person.
  • Sandbox versions drift over time. The bundled specs cover 20.15, 20.16, and 20.18; if DevNet rolls forward, add a new spec folder (see specs/README.md).
