Multivendor Device Query

Query network devices on platforms NetClaw's Cisco- and Juniper-specific servers cannot reach — MikroTik RouterOS, VyOS, SONiC, Nokia SR Linux, Extreme, Huawei, Dell, Ubiquiti EdgeOS, and roughly eighty more.

MCP server: multivendor-cli-mcp (results identify themselves as multivendor-cli)

Decide which server to use FIRST

This skill is wrong for most Cisco and Juniper work. Check here before using it:

| Your device | Use | |---|---| | Cisco IOS / IOS-XE / NX-OS / IOS-XR | pyats-* skills — ~2000 Genie parsers, state diffing | | Juniper Junos | junos-network skill — PyEZ/NETCONF | | Streaming telemetry, any vendor | gnmi-telemetry skill | | No direct reachability | radkit-remote-access skill | | Anything else | this skill | | "Compare X across Cisco and Arista and Nokia" | this skill (read-only) |

That last row is the exception worth understanding. NAPALM returns one shape across vendors, so this is the only server that can answer a genuinely cross-vendor question. It answers those read-only, even on Cisco and Juniper.

Configuration writes on Cisco and Juniper are refused, naming the correct server. That is deliberate, not a limitation: one write path per platform is what makes "verify the change" mean something. Reads may overlap between servers; writes may not.

Tools

| Tool | Purpose | |---|---| | server_info | Server identity, read-only vs write mode, which platforms have destructive-syntax modelling | | check_command_policy | Would this command be permitted? Answers without touching a device | | list_devices | Inventory, with the source that answered and why | | check_device_readiness | Is this device resolvable, authenticable, and mine to act on? Contacts nothing |

Workflow

1. list_devices — confirm the device is in inventory and see owning_server. If that is

pyats or junos-mcp, stop and use that server for single-device work.

1. check_device_readiness — verify credentials resolve and check what this server may do.

Run this before anything else on a new device: it separates not in inventory from credentials missing from owned by another server, which need three different fixes.

1. check_command_policy — before an unusual command, confirm it passes policy.

Reading the results

source_used names which inventory source answered: live_sot, generated, or operator. When it is not live_sot, fallback_reason says why — treat those results as potentially stale.

credential_path says vault or environment. Both are supported; Vault is not required.

status: refused with owning_server means routing sent you elsewhere. This is a successful call, not an error — read refused_reason and use the named server.

Safety

Read-only by default; write tools are absent from the tool list unless an operator sets MULTIVENDOR_WRITE_ENABLED. Command filtering is enforced server-side, so it cannot be bypassed by rephrasing a request. Evaluation order: chaining (;, &&, ||, >, <) is rejected first, then per-platform destructive verbs, then the read-only allowlist.

Chaining is checked first because show version; write erase begins with an allowlisted verb.

A single | is fine — on network devices that is a display filter, not a shell pipe.

Environment variables

See .env.example for the full set. MULTIVENDOR_INVENTORY_SOURCE, MULTIVENDOR_INVENTORY_PATH, MULTIVENDOR_USERNAME/MULTIVENDOR_PASSWORD, MULTIVENDOR_WRITE_ENABLED. Never put credentials in an inventory file — the server rejects inventory records containing credential-shaped fields.

Caveat worth knowing

Netmiko also drives Fortinet, PAN-OS and Check Point, so this server gives CLI-level reach to them. That is not equivalent to their dedicated API integrations — FortiManager's policy-package model and Panorama's device groups have no CLI equivalent. Do not treat CLI reach as full vendor support.

Caveat: CLI reach is not full vendor support

netmiko also drives Fortinet, Palo Alto PAN-OS and Check Point, so this server gives CLI-level reach to them today. That is not equivalent to their dedicated API integrations:

| Vendor | What CLI gives you | What it does NOT give you | |---|---|---| | Fortinet | FortiOS CLI reads | FortiManager policy packages, ADOM model, install preview | | Palo Alto | PAN-OS CLI reads | Panorama device groups, templates, commit validation | | Check Point | GAiA CLI reads | Management API policy layers, threat intel |

Roadmap items R3 (Fortinet) and R4 (Palo Alto) are still needed. Do not treat CLI reach as completing them.
