6 tools offered to AI assistants
validate_tree· Checks a behavior tree for errors: missing or dangling children, nodes with two parents, cycles, decorators with more than one child, leaves with children, unknown node names, and BehaviorTree.CPP import problems. Returns valid (true when tcreate_editor_link· Returns a url that opens the tree in the behaviortrees.com editor in the user's browser, auto-laid-out and editable, with no account needed. The tree travels inside the link (the URL fragment), so nothing is uploaded or stored. Fails with tconvert_tree· Convert between behavior3 JSON and BehaviorTree.CPP XML (v4 for ROS 2 Jazzy and Groot2, v3 for ROS 2 Humble), the same way the editor imports and exports. Returns the converted text and any issues (BT.CPP has no equivalent for some behaviorlist_node_types· The built-in behavior3 nodes a tree can use without declaring them: composites (Sequence, Priority = selector/fallback, MemSequence, MemPriority), decorators (Inverter, Repeater, MaxTime, ...) and leaves (Wait, Succeeder, Failer, ...), withget_example· Complete, working example trees (enemy patrol, cooldown-gated attacks, robot navigation with recovery, and more) to learn the format from or start with. Without an id, lists the examples; with an id, returns that tree as behavior3 JSON.read_guide· Practical guides from behaviortrees.com/learn as Markdown: what behavior trees are, node types, blackboards, debugging, structuring large trees, and behavior trees in Unity, Unreal, Godot, Python and robotics (BehaviorTree.CPP, ROS 2, Nav2)
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
