Connect MCP with Cerebrum
The recommended way to connect an MCP server is to ask Cerebrum in chat. Describe the server you want to add, and the agent will guide you through the required details. MCP connections are personal to your Ardor account. Once connected and enabled, the server becomes available to your agent sessions.
Ask Cerebrum to connect MCP
Start with a message such as “Connect our Jira MCP server”, “Add an MCP server for Metabase”, or “Help me set up this MCP endpoint.”
Provide connection details
Cerebrum may ask for the server URL, namespace, transport, and authentication method.
Complete authorization
If the server uses OAuth, follow the authorization link. If it uses a token or custom headers, provide the credentials when Cerebrum asks for them.
Let Cerebrum test the server
Cerebrum checks the connection and reads the available tools, resources, and prompts.
- “Connect an MCP server named
docsathttps://mcp.example.comusing Streamable HTTP.” - “Add our analytics MCP server. It uses OAuth.”
- “Set up a Jira MCP connection with bearer token authentication.”
- “Check whether the new MCP server exposes prompts or resources.”
Connection Fields
| Field | What it means |
|---|---|
| Name | A readable label for the connection in settings. |
| Namespace | A short prefix Ardor uses to distinguish this server’s tools and resources from other MCP servers. |
| Server URL | The URL of the remote MCP server. |
| Transport | The protocol used to connect. Ardor supports Streamable HTTP and SSE. |
| Auth | The authentication method for this server: none, bearer token, custom headers, or OAuth. |
Use MCP in Chat
Once a connection is enabled, Cerebrum can use its MCP tools while you talk to the agent. You can ask in plain language; you do not need to call the tool manually. Examples:- “Use our docs MCP server to find the latest onboarding guide and summarize it.”
- “Check the analytics MCP server for yesterday’s signup count.”
- “Create a Jira issue for the bug we just discussed.”
- “Read the customer record from the CRM MCP server and explain the renewal risk.”
Reference MCP Resources
Some MCP servers expose resources, such as documents, schemas, saved queries, dashboards, or records. You can reference these resources from the chat composer with@, the same way you reference Ardor objects.
Choose MCP resources
Select the MCP resource group and pick the resource you want Cerebrum to inspect.
Use MCP Prompts
If an MCP server exposes prompts, they appear in the slash command picker.
MCP prompts are useful for reusable workflows owned by the external system, such as support triage, query generation, incident review, or domain-specific analysis.
Use MCP Apps in the UI
Some MCP tools can return an interactive MCP App instead of only text. When this happens, Ardor shows an MCP App card directly in the chat. An MCP App can be a dashboard, picker, editor, visualization, form, or another small interface supplied by the MCP server. You can interact with it without leaving the agent session.Ask for something interactive
Ask Cerebrum for a task that the connected MCP server supports, such as exploring a dashboard, choosing records, or working with a visual query tool.
Cerebrum calls the MCP tool
The tool returns an MCP App resource. Ardor detects it and renders an MCP App card in the conversation.
MCP Apps can explicitly share UI state, such as selected records or filters, back to the chat session. If the agent does not understand what you selected, describe it in your next message or ask the app to apply the current selection if it supports that action.
Manage MCP in Settings
The MCP settings page is a reference and management surface. Use it when you want to inspect existing connections or make a direct change without asking the agent. Go to Settings -> Account -> MCP Servers to see each connection’s status, auth type, available tools, resources, prompts, and enabled state.
Add a Server Manually
Connect or authorize
For no-auth, bearer token, or custom header connections, click Connect MCP. For OAuth connections, click Continue to OAuth and complete the authorization flow.
Connection Actions
| Action | Use it when |
|---|---|
| Enabled switch | Temporarily hide or restore a server for agent runs. |
| Auth | Update bearer token or custom header credentials. |
| Authorize | Complete or refresh OAuth authorization. |
| Test | Refresh the server catalog and check whether tools, resources, and prompts are reachable. |
| Delete | Remove the connection and stored credentials from your account. |
Troubleshooting
The MCP server does not appear in chat
The MCP server does not appear in chat
Ask Cerebrum to check the MCP connection. You can also open Settings -> Account -> MCP Servers, confirm that the connection is enabled, and click Test.

Cerebrum used the wrong server

Mention the server namespace in your request, or reference an MCP resource from the
@ picker so the agent has a clear target.An MCP App card shows an error

The app resource may be unavailable, the server may have returned an error, or the app may require authorization. Test the connection and update credentials if needed.
The agent does not understand what I selected in an MCP App
The agent does not understand what I selected in an MCP App
Ask the app to send or apply the current selection if it has that control. Otherwise, describe the selection in your next message.
