Set up

Add Sigma to Goose in four steps

Admins approve the server once. Everyone in Goose 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 Goose to Runlayer

    Users add the Runlayer Plugin as a Goose extension; Goose has no native plugin install. Goose 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 Goose

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

Tools

7 Sigma tools in Goose

Runlayer policy decides which of these Goose 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 Goose

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

  • Gateway policy (available)

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

  • Audit trail (available)

    Each call is recorded with the user, Goose 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 before Goose runs it.

  • Block output after it runs (available)

    Runlayer can block a tool’s output before Goose’s model sees it.

  • Redact output in place (not available)

    Goose cannot apply masking, so Runlayer blocks output it would otherwise mask. The gateway still applies policy to the call.
