Set up

Add Sigma to GitHub Copilot CLI in four steps

Admins approve the server once. Everyone in GitHub Copilot CLI then gets it through the same governed connection.

  1. 1

    Add Sigma to Runlayer

    Sigma isn’t in the Runlayer catalog yet, so an admin adds it by its MCP server URL.

    Adding a connector manually
  2. 2

    Connect GitHub Copilot CLI to Runlayer

    Users add the Runlayer Plugin to GitHub Copilot CLI by following Runlayer’s setup guide. GitHub Copilot CLI reaches Sigma’s 7 tools through the Runlayer Plugin’s search and execute tools instead of listing each one.

  3. 3

    Sign in to Sigma

    Sign in the way Sigma requires. Runlayer holds the credentials so they stay out of the client’s configuration.

  4. 4

    Use Sigma from GitHub Copilot CLI

    Sigma’s approved tools appear in GitHub Copilot CLI. Every call is checked against policy and recorded.

Tools

7 Sigma tools in GitHub Copilot CLI

Runlayer policy decides which of these GitHub Copilot CLI users can call.

  • Begin session

    REQUIRED — You MUST call this tool before using any other Sigma tool in a conversation.

  • Call agent

    Call a Sigma workbook agent with a message or conversation.

  • Describe

    Inspect the schema of a Sigma data source.

  • List documents

    Browse a named document collection in the Sigma workspace.

  • List workbook agents

    List the workbook agents you can edit across your organization

  • Query

    Execute a SQL query against a Sigma data source and return the results.

  • Search

    Search across the entire Sigma workspace to discover workbooks, data models, data model elements, and tables.

Control

What Runlayer can see and stop in GitHub Copilot CLI

Some controls apply to every client at the gateway. Others depend on what GitHub Copilot CLI exposes to Runlayer.

  • Gateway policy (available)

    Every Sigma call from GitHub Copilot CLI passes through Runlayer, where your policies can allow, alert, mask, or block it.

  • Audit trail (available)

    Each call is recorded with the user, GitHub Copilot CLI as the client, the tool, and the policy and scanner decisions.

  • Client hooks (available)

    Capture supported prompts, reasoning, local and MCP tool calls, responses, and scanner decisions in real time.

  • Stop a call before it runs (available)

    Runlayer can deny a tool call or permission request before GitHub Copilot CLI runs it.

  • Block output after it runs (available)

    Runlayer can block a tool’s output before GitHub Copilot CLI’s model sees it.

  • Redact output in place (available)

    Runlayer can mask sensitive parts of a successful tool’s output in GitHub Copilot CLI and pass the rest through.

In GitHub Copilot CLI

  • When a tool fails, Runlayer records the error but cannot replace it.
