How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability66
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1117 tokens (~186/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management3
- Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
convert_tree Convert a behavior tree ~263
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 behavior3 nodes and vice versa).
| Name | Type | Req | Description |
|---|---|---|---|
| to | string | yes | Target format: behavior3, btcpp-v4 or btcpp-v3 |
| tree | – | yes | The tree: behavior3 JSON: {"title": "...", "root": "<id of the first node under the root>", "nodes": {"<id>": {"name": "<node type>", "title": "<optional label>", "children": ["<id>", ...] (composite… |
No output schema declared.
No examples provided.
create_editor_link Open a tree in the editor ~238
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 the validation errors if the tree has any.
| Name | Type | Req | Description |
|---|---|---|---|
| tree | – | yes | The tree: behavior3 JSON: {"title": "...", "root": "<id of the first node under the root>", "nodes": {"<id>": {"name": "<node type>", "title": "<optional label>", "children": ["<id>", ...] (composite… |
No output schema declared.
No examples provided.
get_example Get an example tree ~76
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.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | – | Example id from the list; omit to list them |
No output schema declared.
No examples provided.
list_node_types List built-in node types ~72
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, ...), with descriptions and default properties.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
read_guide Read a behavior tree guide ~91
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). Without a slug, lists the guides.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | – | Guide slug from the list; omit to list them |
No output schema declared.
No examples provided.
validate_tree Validate a behavior tree ~242
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 there are no errors), the trees found, and findings at error, warning or info level.
| Name | Type | Req | Description |
|---|---|---|---|
| tree | – | yes | The tree: behavior3 JSON: {"title": "...", "root": "<id of the first node under the root>", "nodes": {"<id>": {"name": "<node type>", "title": "<optional label>", "children": ["<id>", ...] (composite… |

How do I install the Behavior Trees MCP server?
Behavior Trees is a hosted endpoint at https://www.behaviortrees.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the Behavior Trees MCP server?
Behavior Trees is an MCP server listed in the public MCP registry as io.github.behaviortrees/behaviortrees. Validate, convert (behavior3 JSON, BehaviorTree.CPP XML) and open behavior trees in a visual editor. This page covers its hosted endpoint (https://www.behaviortrees.com/mcp).
Is the Behavior Trees MCP server safe to use?
Behavior Trees scores 74 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Behavior Trees MCP server expose?
Behavior Trees exposes 6 tools: validate_tree, create_editor_link, convert_tree, list_node_types, get_example, read_guide. Their descriptions and schemas cost roughly 982 tokens of context every time the server is loaded.
Does the Behavior Trees MCP server require authentication?
No. We connected to Behavior Trees without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Behavior Trees MCP server still maintained?
Behavior Trees is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
