RouterOS Command Tree & /console/inspect

Overview

RouterOS organizes all configuration and commands in a hierarchical tree. Every path in the CLI (like /ip/address/add) corresponds to a node in this tree. The /console/inspect REST endpoint lets you programmatically explore the entire tree — this is how tools like restraml (RAML/OpenAPI schema generator) and rosetta (MCP command lookup) build their databases.

The Command Tree Structure

RouterOS's command hierarchy has four node types:

Tree Example

/ (root dir)
├── ip/ (dir)
│   ├── address/ (path)
│   │   ├── add (cmd)
│   │   │   ├── address (arg) — "IP address"
│   │   │   ├── interface (arg) — "Interface name"
│   │   │   └── disabled (arg) — "yes | no"
│   │   ├── set (cmd)
│   │   ├── remove (cmd)
│   │   ├── get (cmd)
│   │   ├── print (cmd)
│   │   └── export (cmd)
│   ├── route/ (path)
│   │   └── ...
│   └── dns/ (path)
│       ├── set (cmd)
│       ├── cache/ (path)
│       │   ├── print (cmd)
│       │   └── flush (cmd)
│       └── ...
├── interface/ (dir)
│   └── ...

/console/inspect API

Endpoint

POST /rest/console/inspect

Requires basic authentication. Available on all RouterOS 7.x versions.

Request Types

Listing Children

// List children of /ip
const children = await fetch(`${base}/console/inspect`, {
  method: "POST",
  headers: { ...authHeaders, "Content-Type": "application/json" },
  body: JSON.stringify({
    request: "child",
    path: "ip",
  }),
}).then(r => r.json());

// Response:
// [
//   { "type": "child", "name": "address",    "node-type": "path" },
//   { "type": "child", "name": "arp",        "node-type": "path" },
//   { "type": "child", "name": "cloud",      "node-type": "path" },
//   { "type": "child", "name": "dhcp-client", "node-type": "path" },
//   { "type": "child", "name": "dns",        "node-type": "path" },
//   { "type": "child", "name": "route",      "node-type": "path" },
//   ...
// ]

Getting Syntax Help

// Get description for /ip/address/add → address argument
const syntax = await fetch(`${base}/console/inspect`, {
  method: "POST",
  headers: { ...authHeaders, "Content-Type": "application/json" },
  body: JSON.stringify({
    request: "syntax",
    path: "ip,address,add,address",   // comma-separated path
  }),
}).then(r => r.json());

// Response:
// [{ "type": "syntax", "text": "IP address" }]

Path Format

The path field uses comma-separated segments (not slashes):

• Root: "" (empty string)
• /ip: "ip"
• /ip/address: "ip,address"
• /ip/address/add: "ip,address,add"
• /ip/address/add → address arg: "ip,address,add,address"

When using the JavaScript Array.toString() method, this comma-separated format is produced naturally from an array: ["ip", "address", "add"].toString() → "ip,address,add".

Tree Traversal Pattern

To walk the entire tree recursively:

async function walkTree(path = [], tree = {}) {
  const children = await fetchInspect("child", path.toString());

  for (const child of children) {
    if (child.type !== "child") continue;

    const childPath = [...path, child.name];
    tree[child.name] = { _type: child["node-type"] };

    // For args, fetch the syntax description — but NOT inside dangerous subtrees
    if (child["node-type"] === "arg") {
      if (DANGEROUS_PATHS.some(p => childPath.includes(p))) continue;

      const syntax = await fetchInspect("syntax", childPath.toString());
      if (syntax.length === 1 && syntax[0].text.length > 0) {
        tree[child.name].desc = syntax[0].text;
      }
    }

    // Recurse into this child (child enumeration is safe even in dangerous subtrees)
    await walkTree(childPath, tree[child.name]);
  }

  return tree;
}

Dangerous Paths — Conservative Skip Policy

Old RouterOS versions can deadlock the REST server when scripting-keyword paths are queried for syntax/completion via /console/inspect. Crawlers conservatively skip syntax lookups inside subtrees containing any of these names:

where, do, else, rule, command, on-error

These are RouterOS scripting constructs. Treat the six-path list as a conservative crawler skip policy, not a timeless crash invariant: live probing in tikoci/restraml (MikroTik support case SUP-127641) isolated the confirmed deadlock to bare do with request=syntax/completion on RouterOS ≤7.20.8 — the other five paths return [] instantly there — and found it fixed by 7.21.4. (The original six-path folklore came from sequential probing: once do hangs the server, every path tested after it appears to crash too.) Enumerating children (child request) is safe on all tested versions, as are nested paths like ["do","command"].

The conservative approach (used in the example above) skips the entire arg when any ancestor matches a dangerous path, and pairs every request with a short timeout on old or unknown versions. The actual rest2raml.js implementation matches this pattern.

const DANGEROUS_PATHS = ["where", "do", "else", "rule", "command", "on-error"];

CLI Command → REST Verb Mapping

RouterOS CLI commands map to HTTP verbs in the REST API:

Key insight: REST PUT = create, PATCH = update. This is the opposite of many REST API conventions where PUT is idempotent update and POST is create.

RAML/OpenAPI Schema Generation

When generating API schemas from the command tree:

1. Walk the tree to collect all paths, commands, and arguments
2. For each cmd node:

- get → generates both GET /path (list) and GET /path/{id} (single) - add → generates PUT /path with arg-based request body - set → generates PATCH /path/{id} with arg-based request body - remove → generates DELETE /path/{id} - Other commands → POST /path/command

1. For each arg under a command, generate request body properties or query parameters
2. The desc field from syntax lookups becomes the description

The .proplist and .query Parameters

All POST-based command endpoints accept two special parameters:

• .proplist — selects which properties to return (like SQL SELECT)
• .query — filter expression array (like SQL WHERE)

These are RouterOS REST API conventions, not standard REST patterns.

Output Formats

The inspect tree can be converted to multiple schema formats:

inspect.json (Raw Output)

The raw tree as returned by recursive /console/inspect calls. Each node has:

{
  "address": {
    "_type": "path",
    "add": {
      "_type": "cmd",
      "address": { "_type": "arg", "desc": "IP address" },
      "interface": { "_type": "arg", "desc": "Interface name" }
    },
    "set": { "_type": "cmd", ... },
    "print": { "_type": "cmd", ... }
  }
}

RAML 1.0 (schema.raml)

Converted to RAML 1.0 resource/method notation:

/ip:
  /address:
    get:
      queryParameters: ...
      responses: ...
    put:
      body:
        application/json:
          properties:
            address: { type: any, description: "IP address" }
    /{id}:
      get: ...
      patch: ...
      delete: ...

OpenAPI 3.0 (openapi.json)

Standard OpenAPI 3.0 schema generated from the same inspect tree (7.21.1+).

The inspect.json Data Model

Each version's inspect.json is the canonical source of truth for that RouterOS version's command tree. It captures:

• Every navigable path in the CLI hierarchy
• Every executable command at each path level
• Every argument (parameter) for each command
• Syntax descriptions for arguments

Tools can parse inspect.json offline without needing a live router — set INSPECTFILE env var and the schema generator will use the cached file instead of querying a router.

Common Patterns for Working with the Tree

Finding Commands at a Path

// Given an inspect.json node for /ip/address
const node = inspectData.ip.address;

// Commands are children with _type === "cmd"
const commands = Object.entries(node)
  .filter(([key, val]) => val._type === "cmd")
  .map(([key]) => key);
// → ["add", "set", "remove", "get", "print", "export", ...]

Finding Arguments for a Command

// Arguments of /ip/address/add
const addCmd = inspectData.ip.address.add;
const args = Object.entries(addCmd)
  .filter(([key, val]) => val._type === "arg")
  .map(([key, val]) => ({ name: key, description: val.desc }));
// → [{name: "address", description: "IP address"}, ...]

Traversing Directories

// Directories and paths (navigable children)
const children = Object.entries(node)
  .filter(([key, val]) => val._type === "dir" || val._type === "path")
  .map(([key]) => key);

Performance Notes

• Full tree traversal takes many minutes against a live router (thousands of HTTP requests,

each a separate POST to /console/inspect). With KVM acceleration the CHR responds quickly, but the sheer number of sequential requests adds up.

• Each /console/inspect call is a separate HTTP request — no batch API
• Use INSPECTFILE for development/testing to avoid repeated live queries
• The tree is version-specific — different RouterOS versions have different command sets
• Extra packages (container, iot, zerotier, etc.) add additional command tree branches

Additional Resources

• MikroTik's new manual site has a browsable CLI Reference at

<https://manual.mikrotik.com/docs/CLI%20Reference/>;. It exposes command menus, flags, argument names, and types by package/path (for example, /docs/CLI%20Reference/system/ip/address). Treat it as the human-readable companion to /console/inspect; when it disagrees with a live router, /console/inspect from that router wins.
