Radius MCP and web search

Radius runs an MCP server that lets Pi set up and manage Radius for you. It exposes Radius API operations as tools, including organization settings, members, groups, budgets, models, analytics, artifacts, and web search.

Set up Radius MCP in Pi

When /login radius finishes, Pi asks whether to configure the Radius MCP server in ~/.pi/agent/mcp.json. Choose Yes. Pi adds the server, configures it to use your Radius login, and reloads the session to connect it.

If you skipped that step, add this configuration to ~/.pi/agent/mcp.json:

{
  "mcpServers": {
    "radius": {
      "url": "https://radius.pi.dev/mcp",
      "auth": { "provider": "radius" }
    }
  }
}

Run /reload in a running session to connect the server. Use /mcp to inspect its tools or reconnect.

You can also authorize the server separately from your Radius provider login:

pi mcp add radius --url https://radius.pi.dev/mcp
pi mcp login radius

Web search is powered by Parallel Web Systems and is off by default. An organization owner or admin can turn it on by asking Pi or using the organization's Web search page.

See Pricing and billing for the available web search options, prices, and data-retention details.

Once search is enabled, ask Pi to search the web; it can use the Radius web-search operation through MCP, or through this extension:

pi install npm:@earendil-works/pi-radius-web-search
