Credible supports Cursor, VS Code, and Claude Code (running in VS Code) as IDEs for building semantic models. The Credible Extension connects your IDE to the Credible platform, giving the AI agent the tools and context it needs to help you build, validate, and publish semantic models. The steps below use Cursor as the example, but the same workflow applies to VS Code and Claude Code in VS Code.

​
Prerequisites

  • Cursor, VS Code, or VS Code with Claude Code installed (latest version recommended)
  • Credible organization set up by an admin
  • Database connections configured — Your organization admin should have set up connections to your data sources. See Connect to Your Data.

​
What the Credible Extension Provides

The Credible Extension configures your IDE workspace with everything the agent needs for semantic modeling:
  • Credible-Modeling MCP server — A project-scoped MCP server that gives the agent access to your data warehouse metadata, so it can discover tables, suggest modeling approaches, and look up Malloy syntax
  • Modeling skills — Slash commands (e.g., /malloy-model, /malloy-discover, /credible-publish) that guide the agent through common workflows. The agent uses these automatically based on context
  • Cursor rules — Malloy-aware coding rules that help the agent write correct Malloy syntax and follow best practices
  • Managed database connections — Access connections configured in the Credible App without storing credentials locally
  • Credible Service Panel — Browse your organization’s projects, connections, and published packages
Installing the Credible Extension also installs the Malloy extension, which provides:
  • Syntax highlighting & compilation checks for .malloy, .malloynb, and .malloysql files
  • Schema | Explore | Preview buttons above any source definition
  • Run | Show SQL buttons above any query or run statement

​
Installation

​
Install the Credible Extension & Log In

  1. In Cursor or VS Code, go to the Extensions view (Cmd+Shift+X on Mac, Ctrl+Shift+X on Windows/Linux), search for Credible, and install the extension — select Auto Update when prompted
  2. Open the Explorer (Cmd+Shift+E on Mac, Ctrl+Shift+E on Windows/Linux), expand the Credible panel at the bottom of the sidebar, and click Login — then follow the steps in your browser
  3. Back in your IDE, select your organization from the list (if you only belong to one, it’s selected automatically), then select your project

​
Enable the Credible-Modeling MCP Server

The Credible Extension writes a workspace-scoped MCP config (.cursor/mcp.json or .vscode/mcp.json) that points to a project-specific modeling MCP server. After logging in, you’ll see a pop-up prompting you to enable it — click through to turn it on. Pop-up prompting to enable the Credible-Modeling MCP server If you dismissed the pop-up or your agent can’t access MCP tools, follow the steps for your IDE:
  1. Open Cursor Settings (Cmd+Shift+J on Mac, Ctrl+Shift+J on Windows/Linux)
  2. Navigate to Tools & MCP
  3. Find Credible-Modeling and toggle it on
  4. If the agent still can’t call MCP tools, reload the window (Cmd+Shift+P → “Reload Window”)
Every time you change projects, the extension updates the MCP config. You may need to re-enable the server using the steps above.

​
Credible Service Panel

The Credible Service Panel shows your organization’s structure. Find it at the bottom of the Explorer view (Cmd+Shift+E on Mac, Ctrl+Shift+E on Windows/Linux): Credible Service Panel in Cursor Here you can view:
  • Projects: Logical groupings of related packages and connections
  • Connections: Managed database connections (no local credentials needed)
  • Packages: Published semantic models with version history
The extension automatically discovers connections in your project, eliminating the need to store database credentials locally.
The sidebar may be hidden by default in Cursor:
  1. Open the Explorer panel (Cmd+Shift+E) (or Ctrl+Shift+E on Windows/Linux)
  2. Look for the Credible panel at the bottom of the explorer sidebar
The Credible Extension can be configured via the Command Palette (Cmd+Shift+P) or clicking icons in the Credible Service panel:
  • Disable Credible: Turn off the extension for this workspace
  • Refresh: Reload projects, connections, and packages
  • Select Organization: Choose from your available organizations (auto-selects if you only belong to one)
  • Sign Out: Log out of Credible
Click on a project to switch projects — you’ll see a list of available projects in the command palette.
