Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00074 | $0.02041 |
| Opus 5 | $0.00037 | $0.01020 |
| Sonnet 5 | $0.00015 | $0.00408 |
| Haiku 4.5 | $0.00007 | $0.00204 |
Grade A, and why
agents scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agents
Overview
Four AI agent document types stored as JSON inside Mendix MPR files:
| Type | CREATE keyword | Notes |
|---|---|---|
| Model | create model |
GenAI model configuration; required by Agent |
| Knowledge Base | create knowledge base |
KB source; referenced by Agent body |
| Consumed MCP Service | create consumed mcp service |
MCP tool server; referenced by Agent body |
| Agent | create agent |
Orchestrates model + tools + prompts |
Requires: Mendix 11.9+ and the full agent-editor marketplace stack (7 modules) —
AgentEditorCommons depends transitively on the other six, so all must be installed:
| Module | Role |
|---|---|
GenAICommons |
Core AI types (Request/Response, DeployedModel, Tool, KnowledgeBase) |
MxGenAIConnector |
Mendix Cloud AI backend, model config, embeddings |
AgentCommons |
Agent management (versioned agents, tools, KBs, MCP) |
AgentEditorCommons |
Bridge to the Studio Pro Agent Editor extension |
MCPClient |
MCP server connections, tool discovery/execution |
ConversationalUI |
Chat widgets, tool-approval UI, trace monitoring |
Encryption |
Provides the 32-char key models/KBs reference |
Install them with mxcli marketplace install <id> -p app.mpr (or via Studio Pro). Also
register ASU_AgentEditor as an after-startup microflow.
Syntax
Model
create model Module.MyModel (
Provider: MxCloudGenAI, -- default, can omit
key: Module.ApiKeyConst -- must be a String constant
);
Provider is free-form, and nothing validates it. MDL passes the value
straight through; MxCloudGenAI is only the default applied when you omit the
property, not the only accepted value. Provider: OpenAI parses, writes, and
round-trips through describe model — as does Provider: TotallyMadeUp.
That means a typo is caught by nothing in the headless path. Agent Editor
documents are stored as custom blobs, and mxbuild contains no agent-editor
strings at all, so mx check and the build both stay green and the fault
surfaces only when Studio Pro opens the document.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

agents is a skill published in the GitHub repository mendixlabs/mxcli (115 stars, last pushed 2d ago), licensed Apache-2.0. It adds 74 tokens to every session and 2,041 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
