At a Glance
Any MCP-compatible assistant can ask. appRules decides what actually happens.
AI assistants have become where people work — business users in assistants such as Claude Desktop, developers in Cursor and Windsurf, and Microsoft 365 teams building agents in Copilot Studio. Assistants like these can call external tools through the Model Context Protocol (MCP), the open standard for connecting AI assistants to the systems around them.
appRules exposes its workflow execution engine as a native MCP Server. That means MCP-compatible assistants can discover appRules workflows, invoke them in natural language, and receive their results — while every action on enterprise systems still runs through governed appRules workflows, with validated inputs, tested actions, and a tamper-proof record of every step.
Examples of MCP-Compatible Assistants
| Assistant | Who Uses It | How Teams Could Use appRules |
|---|---|---|
| Claude Desktop | Business users and knowledge workers | Ask in plain language for a governed workflow to run — for example, checking a customer record, running a data-quality review, or starting a scheduled process — and get the results back in the conversation |
| Cursor | Developers | Invoke appRules workflows from the editor while building — for example, running a validation workflow against test data without leaving the IDE |
| Windsurf | Developers | Call the same governed workflows from Windsurf's agent, with every action still validated, executed, and logged by appRules |
| Microsoft Copilot Studio | Microsoft 365 agent builders | Give Copilot Studio agents governed appRules workflows as tools, so Microsoft agents can act on enterprise systems through appRules |
These are examples of popular assistants that support MCP; any MCP-compatible client can connect the same way. Because support for custom MCP servers depends on each assistant's plan, version, and configuration, we recommend confirming connectivity in your own environment.
How It Works
Expose
Make selected appRules workflows available through the appRules MCP Server — no middleware and no custom integration code.
Discover
The assistant sees the available workflows as tools it can call, each with its inputs and purpose.
Invoke
A user asks in natural language, and the assistant calls the right workflow with the right inputs.
Govern and Return
appRules validates the inputs, runs only tested actions, logs every step, and returns the results to the assistant.
Why Route AI Assistants Through appRules
The Assistant Asks, appRules Acts
The assistant supplies the intelligence; appRules holds the authority. No assistant writes to your CRM, ERP, or databases directly — it calls a governed workflow that does. See Contain the Model.
One Governed Path, Every Assistant
Whether a request comes from Claude Desktop, Cursor, Windsurf, or a Copilot Studio agent, it runs through the same Conditions, the same validated Actions, and the same rules.
Standards-Based, Not Custom-Built
MCP is an open standard, so one appRules MCP Server serves every compatible assistant — instead of a separate integration for each tool your teams adopt.
Control and Evidence
Tamper-proof logs record every invocation and its outcome, authorized users can pause or cancel any run mid-task, and sensitive records stay locked with the Secure button.
Choosing the Right Tool for Each Job
Let AI assistants handle
Conversation, reasoning, writing, research, and coding — and turning what a person asks for into a request for the right workflow.
Let appRules handle
Every action on enterprise systems — reading and writing CRM, ERP, HR, and database records — with GuardRailed Automation, a mature rules engine, and tamper-proof evidence of every run.
