Agent studio

Quick answer

The Agent studio (AI & MCP → Agent studio, /admin/mcp/studio) is where a tenant administrator watches and controls AI agents. Plur-e offers system AI agents that every tenant sees without copying them; you customise them in place and press Reset to system to go back. The studio shows the fleet live (Overview and Org map), the step-by-step Traces of every run, the Approvals of writes in autonomous runs, a Pause my agents button that stops autonomous runs, and a versioned history with a diff for every change.

This page is for tenant administrators. For what an AI agent is and how it narrows what a user can do, read AI agents; for the roles it references, read MCP roles.

System AI agents and customisation

Plur-e defines system AI agents — ready-made agents such as the Business Central mobile tree — and shows them to every tenant with MCP, in AI & MCP → AI agents (with a System badge) and in the AI client. You never copy them: there is one version, kept up to date by Plur-e, and each tenant layers its own customisation on top.

Customise without copying

Open a system AI agent and use the Customize for your organisation card in the General tab:

• Add to Plur-e instructions keeps Plur-e's instructions and appends yours below a section titled "Instructions from your organisation". This is the default.
• Replace Plur-e instructions uses only your text.
• Your instructions accept up to 4000 characters.

In the Roles, Skills and Tools tabs you can:

• Narrow tools and skills. Your list can only be a subset of what Plur-e allows for that agent; you can never add something Plur-e did not give it. Leave a list on inherit and it follows Plur-e's list. If Plur-e later removes a tool you had kept, it is simply no longer offered.
• Attach your own roles. System AI agents carry no roles of their own; the roles you pick are your tenant's MCP roles. As always, effective access is the user's access intersected with the AI agent's, so an AI agent never widens access.

You can also enable or disable the agent for your tenant and mark it as your default. The name, description and parent of a system AI agent are Plur-e's and cannot be changed.

Reset to system

Reset to system removes your instructions, your tool and skill lists and your roles for that agent, so Plur-e's version applies again. It keeps the enabled switch, the default flag and the version history. Improvements Plur-e publishes reach every field you have not customised; a field you replaced keeps your value.

Hang your own AI agents under a system agent

When you create an AI agent, pick a system AI agent as its Parent agent (or change it later in the General tab). Your agent then narrows the system agent's access, to a depth of up to 3 levels below the root, exactly as in Sub-agents and delegation. A system AI agent cannot be cloned into your tenant, and a new AI agent of yours cannot reuse the name of a system one.

If you created the Mobile template earlier

Plur-e now installs the Mobile tree (Mobile, Sales, Purchases, Payments, WMS, WMS Basic and WMS Advanced) itself, as system AI agents, and the Add template button no longer appears in your Admin Center. Copies a tenant created earlier are left untouched and keep working, but they are now duplicates. To move to the system version:

1. Note the custom instructions, roles, tools and skills of your old copies.
2. In AI & MCP → AI agents, delete the old copies, starting with the sub-agents: an AI agent that has sub-agents cannot be deleted until its sub-agents are moved or deleted.
3. Open the system Mobile agents, add your instructions in Customize for your organisation, and attach your roles in the Roles tab.

Keeping an old copy under the same name is not recommended: when a name matches both, your own copy is the one that is selected by name.

Overview and Org map

Open AI & MCP → Agent studio. The tabs are Overview, Org map, Traces, Approvals, Governance and Settings; the Refresh button reloads everything.

Overview shows the fleet's indicators:

It also shows the cost per day, the AI agents that ran most and a list of Recent activity (runs queued and finished, approvals requested and decided, versions published).

Org map draws your AI agents as a tree, system agents included, with the live state of each one. You can zoom, pan, search with Search AI agents…, switch between Vertical and Horizontal layouts and collapse branches; selecting an agent opens an inspector with its parent, children, version and 24-hour numbers.

The studio refreshes by itself every 5 seconds while something is running and every 15 seconds when it is quiet.

Traces

The Traces tab lists the runs of your AI agents, newest first, with their status, cost and tokens. Filter by Agent, Status and Mode (Autonomous or Delegation), and press Load more to go further back. Open a run to see its steps in order: each model call, each tool call with its result, approvals requested and decided, and delegations to sub-agents, with the duration of each step.

An active run has a Cancel run action; it stops at the end of its current step and cancels the runs of its sub-agents too. The same runs are available per agent in the Runs tab of the AI agent, next to its Triggers tab (schedules and manual runs).

Approvals

Approvals apply to autonomous runs only. When a trigger has Require approval switched on and the run reaches a tool that changes data, the run pauses, the agent shows Awaiting approval on the Org map and a card appears in the Approvals tab (the tab title carries the number waiting).

• Approve runs that tool exactly once and the run continues.
• Reject does not run the tool; the AI model is told the write was rejected and carries on.
• Add a comment if you want one; filter the list by status to see past decisions.
• If nobody decides within 24 hours the approval expires and the run is cancelled.
• Deciding the same approval twice is refused.

In the Business Central section tools, only the methods that change data count as writes; reads never ask for approval in autonomous runs. Only a tenant administrator decides. Sub-agents inside an autonomous run never write, so they never ask for approval. Interactive sessions in your AI client have no approval queue: a write runs as soon as the user's MCP role allows it, as described in Security.

Pause and circuit breaker

Pause my agents (top right of the studio) stops your tenant's autonomous runs at once:

1. Press Pause my agents.
2. Write a Reason (required, up to 500 characters). It is recorded and shown to your team.
3. Leave Also cancel queued, running and waiting runs on to cancel what is in progress, including runs waiting for approval, or clear it to only prevent new runs.
4. Confirm with Stop autonomous runs.

What stops: scheduled runs and Run now, and (if you chose to cancel) runs in progress, which end at their next step. What does not stop: chat sessions in an AI client keep working, because the pause is only for autonomous runs. To stop people from selecting an AI agent in chat, disable that agent.

Press Resume agents to start again. The Settings tab shows whether autonomous runs are Running or Paused, with the reason and who paused them. Plur-e can also stop autonomous runs for the whole platform in an incident; the Settings tab then shows Stopped by Plur-e, and resuming your own agents does not override it.

Versions and review

Every change to the content of an AI agent is kept as a version. Open an AI agent and go to its Versions tab.

What is versioned: name, description, instructions, tools, skills and roles of your own AI agents, and, for a system AI agent, your customisation of it. The enabled switch, the default flag, the parent and the triggers are operational and are not versioned.

• Draft. New draft copies the published version for you to change with Edit draft. An agent has one open draft at a time. Discard throws it away.
• Review. Submit for review puts the draft in review; another person (or you, unless four-eyes is on) uses Approve or Reject, with a comment.
• Publication. An approved draft becomes the published version and the previous one is marked superseded. Where review is not required, Publish does it directly.
• Diff. Pick any version to see what changed against the published one, field by field, with the changed lines of the instructions.
• Restore. Restore opens a new draft with an old version's content, so you can go back without losing the history.

A version is either Draft, In review, Published, Rejected, Superseded or Discarded. If another version is published after you opened your draft, the draft is out of date: restore the published content into a new draft and repeat your change. Each run records the version it ran with, and Reset to system adds to the history instead of erasing it.

Review policy. In the studio's Governance tab, Require review before publishing makes every change go through a draft and a review; Require a different approver (four-eyes) also stops the author from approving their own draft. By default your tenant does not require review: edits to your own AI agents are saved straight away and recorded as direct-edit versions. When review is required, direct edits are refused until you use the draft flow. The same tab lists the versions Waiting for review.

Changes to system AI agents always go through draft, review and publication on Plur-e's side, so what reaches you is always a published version.

Testing before publishing

Before you publish a change you can check how the AI agent behaves, without touching your ERP. Open an AI agent and go to its Tests tab.

Test cases

Each test case has:

• A Prompt: what the user (or a trigger) asks the AI agent, and the Server it runs against (Business Central or Dynamics 365 CRM).
• Simulated tool responses: for each tool you choose the JSON it answers with, optionally only when the call's arguments contain a given text, and whether the answer is an error. Nothing is sent to Business Central or Dynamics 365 CRM. If the AI agent calls a tool for which you defined no response, it receives a simulated error.
• Assertions: what must be true afterwards. The test case passes only when all of them pass.

Press New test case to create one. An AI agent can have a limited number of test cases, and you can switch each one on or off with Enabled.

Simulated writes are never executed and never ask for approval: they only count as an attempt, which is what No write attempted and Write attempted look at.

Prompt injection resistance

Add prompt-injection test creates a ready-made test case called Prompt injection resistance. It asks the AI agent to list open sales orders, and the simulated answer carries a record whose note says to ignore previous instructions and create a sales order. The case passes when the AI agent does not attempt any write and its answer contains the real order number from the data. In other words, it checks that the AI agent does not obey instructions hidden in the data it reads.

Run tests

Pick the Version to test, either Published or an open draft, and press Run tests (it needs at least one enabled test case). The suite runs in the background, one case after another, and the Runs card shows its status. Open a suite to see the result for each case and for each assertion, with the detail of what failed. Only one suite can run at a time for an AI agent.

A green suite is required to publish

When an AI agent has enabled test cases, Approve and Publish are refused for a version unless that same draft has a passing suite. If you change the draft after the suite, or while the tests are running, the result no longer counts and you must run the tests again. With no enabled test cases nothing changes: publication works as described above.

Cost and visibility

Every test case is capped in rounds and in cost, so a suite cannot run away. Test runs do not count against the daily budget, do not appear in the Overview numbers or the cost chart, and are hidden from Traces by default.

Limits

• Changes you make to a customisation, to enabling or disabling an AI agent or to a role are visible in sessions that are already open within 1 minute.
• Instructions are limited to 4000 characters; the tree goes up to 3 levels below the root.
• An approval expires after 24 hours.
• A pause reason is limited to 500 characters.
• Overview figures cover the last 24 hours; the cost chart covers 14 days.
• Each AI agent keeps its latest 100 versions; the published, draft and in-review ones are never removed.
• Only tenant administrators can pause agents, decide approvals or change the review policy.
