6sense remote MCP server connector
The 6sense remote Model Context Protocol (MCP) connector in Mark (Optimizely Agent Platform) brings account intelligence from the 6sense Revenue Marketing Platform into Mark. Mark retrieves 6sense insights so you can research accounts, analyze campaigns, and prepare for meetings without leaving your workflow.
Beta
6sense Model Context Protocol (MCP) is in beta.
The connector is read-only and provides the same data available through Revvy AI. Use it to review account insights and engagement, track 6sense Qualified Account (6QA) trends, analyze keyword and ad campaign performance, monitor website activity, and discover account segments. It does not modify 6sense data or include company and contact enrichment.
The 6sense remote MCP is managed by 6sense. For details, see 6sense Model Context Protocol (MCP) in the 6sense documentation.
First, a Mark administrator must Connect the 6sense remote MCP to Mark. After connecting the MCP server, individual Mark users and agent builders can log in to 6sense to access their information from Mark. Administrators only need to connect the 6sense remote MCP once.
Connect the 6sense remote MCP to Mark
Note
The first person to connect a third-party service to Mark should be an administrator of that service. Administrator access installs the complete set of tools, so Mark adds every available tool. If a non-administrator connects the service first, Mark installs only the tools that account can access.
Mark administrators connect and grant access to 6sense from Mark. After granting access, administrators select which tools to enable in Mark and optionally customize their display names.
Add 6sense connection
As a Mark administrator, complete the following steps:
- Go to Connectors in Mark.
- (Optional) Enter 6sense in the search bar to filter the connectors list.
- Click Connect on the 6sense tile.

- Log in to your 6sense account.

- Configure the connector.

- Click Allow access.
A confirmation message displays and you can close the pop-up window.
Configure Mark tools
After adding the 6sense connection, Mark prompts you to select which tools to enable and optionally customize their display names.
As a Mark administrator, complete the following steps:
- Deselect any tools you do not want to add to Mark.
- (Optional) Update any tool's display name.

- Click Finish.
The 6sense tile displays Connect on the Connectors tab for Mark users to authenticate with their personal accounts.
To update the available tools or names, see Update tools.
Authenticate with 6sense
Each Mark user and agent builder logs in to 6sense individually to access their 6sense data from Mark. User-level authentication ensures you access only the data your 6sense account is authorized to view. When you have access to multiple 6sense instances, Mark keeps each instance's data isolated.
Before you begin, confirm that a Mark administrator has connected 6sense. Until an administrator connects it, the 6sense tile displays Contact admin instead of Connect and you cannot select it.
To authenticate, complete the following steps in Mark:
- Go to Connectors.
- (Optional) Enter 6sense in the search bar to filter the connectors list.
- Click Connect on the 6sense tile.
- Log in to 6sense.
After you connect to 6sense, the 6sense connector tools your administrator added become available in Mark chat, agents, and workflows.
6sense connector tools
The 6sense connector tools are available in Mark after an administrator connects 6sense and you log in. The available tools depend on which tools your administrator enabled. For a full list of available tools and actions, see 6sense Model Context Protocol (MCP) in the 6sense documentation.
Update tools
To rename, add, or remove tools, a Mark administrator must delete the 6sense tools registry and re-add it. To do so, complete the following steps:
- Follow the steps in Delete a tool registry.
