Kiro

Connect Kiro IDE or Kiro CLI to Ternary using Kiro's MCP configuration. Kiro requires Ternary's OAuth client metadata URL.

Before you start

You need:

• An existing Ternary account
• Access to at least one Ternary tenant
• Kiro configured to allow the Ternary MCP server

Step 1: Add Ternary

Open Kiro (the IDE or the CLI uses the same config format). In the IDE, the fastest path is:

1. Open the Command Palette.
   • macOS: Cmd + Shift + P
   • Windows/Linux: Ctrl + Shift + P
2. Search for MCP.
3. Choose Kiro: Open user MCP config for every workspace, or Kiro: Open workspace MCP config for this project only.

You can also open the Kiro panel and select the Open MCP Config icon.

Kiro stores this in a file:

• Every workspace: ~/.kiro/settings/mcp.json in your home folder
• This workspace only: .kiro/settings/mcp.json in the project folder

If the file does not exist yet, Kiro creates it. If it already has other MCP servers, add the "ternary" block inside "mcpServers" instead of replacing the whole file.

Paste the configuration for the region where your Ternary tenant is hosted:

{
  "mcpServers": {
    "ternary": {
      "url": "https://core-api.ternary.app/mcp",
      "oauth": {
        "clientMetadataUrl": "https://core-api.ternary.app/oauth/client-metadata.json"
      }
    }
  }
}

{
  "mcpServers": {
    "ternary": {
      "url": "https://core-api.eu.ternary.app/mcp",
      "oauth": {
        "clientMetadataUrl": "https://core-api.ternary.app/oauth/client-metadata.json"
      }
    }
  }
}

Save the file. Kiro reconnects when you save.

Step 2: Authenticate

After you save, Kiro should connect to Ternary and open a browser sign-in page.

If it does not:

• In the IDE, open the Kiro panel, find ternary, and connect or re-authenticate it.
• In the CLI, run /mcp auth and select ternary.

Then:

1. Sign in with your existing Ternary credentials.
2. Approve the access request.
3. Return to Kiro.

Organization-managed registries

In that case, ask your Kiro administrator to add Ternary to the company's MCP registry. They can use this entry:

{
  "servers": [
    {
      "server": {
        "name": "ternary",
        "title": "Ternary",
        "description": "Ternary technology-spend data.",
        "version": "1.0.0",
        "remotes": [
          {
            "type": "streamable-http",
            "url": "https://core-api.ternary.app/mcp"
          }
        ]
      }
    }
  ]
}

{
  "servers": [
    {
      "server": {
        "name": "ternary",
        "title": "Ternary",
        "description": "Ternary technology-spend data.",
        "version": "1.0.0",
        "remotes": [
          {
            "type": "streamable-http",
            "url": "https://core-api.eu.ternary.app/mcp"
          }
        ]
      }
    }
  ]
}

Step 3: Verify the connection

Confirm that Ternary appears as an available MCP server and that its tools are enabled.
