Pilot and Roll Out
MCP Workspace is available to a limited set of customers. Moveworks is validating the experience and gathering feedback, so capabilities and limits may change. To request access, register your interest.
Try a new server with a small pilot audience before you give it to everyone. A pilot shows whether the assistant picks the server’s tools for real requests, and whether sign-in and results work, before the server competes with the rest of your tool environment.
- Choose a server for an app or use case you do not already cover, and review the tools it exposes.
- Set a small pilot audience in Launch Configuration.
- Test the requests that users need to complete.
- Confirm that the assistant uses the MCP tool, then widen access when failures are diagnosable.
Start after you connect the server and Preview Tools returns its tools.
Choose What to Pilot
How the Assistant Picks a Tool
For each request, the assistant chooses from the MCP servers, Tool Studio plugins, and Enterprise Search available to that user. When more than one tool could handle the request, the assistant can choose the wrong tool or stop before it reaches the MCP server.
For example, Enterprise Search can answer a broad Notion request before a Notion MCP tool is considered, or an existing Linear plugin can win over a new Linear server. Design around the overlap before you expand access.
Start with New Apps and Use Cases
Connect MCP servers for apps and use cases that you do not already cover. A new app or a new use case gives the assistant a clearer choice.
If a server overlaps with an existing tool, expect selection issues. Reduce that overlap before you make the server available broadly.
Keep the Tool Environment Lean
- Preview a server’s tools and review the inventory before you enable it. A single server can expose dozens or hundreds of tools.
- Add servers deliberately. Confirm one works before you connect the next.
- Disable a server that you are not actively using so it does not compete for selection.
The assistant narrows to a relevant set of tools for each request, so raw tool count matters less than overlap and very large individual servers. There is no published hard limit, but treat a server with well over a hundred tools as higher risk and pilot it carefully.
Set the Pilot Audience
After you publish the server, two settings control who can use it. The Enabled toggle turns an MCP server on or off. Launch Configuration controls which users can reach an enabled server. Start with a defined pilot audience instead of launching a new server broadly.

MCP Workspace controls access at the server level. You cannot allow or block individual tools inside a server. Review the full tool inventory before you enable the server, especially when it exposes write actions.
MCP tools run in the Universal Assistant. Productivity Assistant support is not available during Controlled Availability.
Connecting a server does not change upstream permissions. With per-user authorization, the server enforces the employee’s access. With application credentials, it enforces the application’s access. Launch Configuration still controls which employees can reach the server.
What Users Do the First Time
For per-user authorization, the first time a user asks the assistant to use a connected app, the assistant can prompt them to sign in within the conversation. After they complete sign-in, later requests can use the server without prompting again. Ask each pilot user to complete this sign-in when prompted.

If a server works for some users but not others, check their audience access, upstream permissions, and sign-in. If a stored token fails, use the authentication recovery steps.
Test with Real Requests
Ask pilot users to name the app and the item they need. Specific requests make it easier for the assistant to select the intended tool.
Use these request types in the pilot:
For bulk actions and multi-app work, name the apps and state each intended step. The assistant does not automatically compose a complex cross-app workflow from a vague goal, and one MCP tool call does not automatically trigger a tool on another server.
Validate the Connection Before Rollout
Use the requests your employees need, including the slowest retrieval and the cases most likely to fail.
Check Which Tool Ran
Use More info > Reveal AI Reasoning on a response to check whether the assistant called an MCP tool. MCP tool calls use the format mcp__<server>__<tool>.
If the assistant selects a plugin or Enterprise Search instead, you have a tool-selection issue. See Use Temporary Testing Levers Carefully. If it selects the expected MCP tool but the result is wrong or the call fails, find the MCP tool call log and work through Troubleshooting.
Use Temporary Testing Levers Carefully
You may need to change the surrounding tool environment to understand a pilot result. These are testing levers, not permanent configuration.
Enterprise Search provides functionality that users may rely on. If an MCP server only works with it off, reduce the overlap between the MCP tools and Enterprise Search instead.
Widen Access
Keep the tested requests, unexpected results, and server or connector changes with the pilot record. Use that evidence to decide whether to widen the Launch Configuration audience, improve the server, or build a plugin instead. Widen the audience only when the assistant uses the MCP tool for the pilot requests and failures are diagnosable.
