Agent tools

The services used by NativeExpress provide tools that let your coding agent inspect and configure your accounts.

Service	What your agent can do	Setup instructions
RevenueCat	Configure projects, products, entitlements and offerings; inspect purchases	AI toolkit
Supabase	Query data, manage migrations and deploy edge functions	MCP server
Expo	Read Expo guidance and work with EAS builds	Agents
Sentry	Inspect issues, stack traces and performance data	Sentry MCP
PostHog	Query analytics and manage project resources	MCP
OneSignal	Manage users, segments and messages	MCP
Superwall	Manage projects, paywalls, products and campaigns	MCP

Follow the vendor’s installation instructions for your agent. A skill provides instructions; an authenticated MCP connection provides account access. Installing skills alone does not connect the vendor account.

MCP server addresses

Service	Address
Supabase	`https://mcp.supabase.com/mcp`
Sentry	`https://mcp.sentry.dev/mcp`
OneSignal	`https://api.onesignal.com/mcp/oauth`
Superwall	`https://superwall-mcp.superwall.com/mcp`

The following example connects Supabase. Replace <your-project-ref> with your project reference. The URL scopes the connection to that project and makes database queries read-only.

Claude Code


claude mcp add --scope project --transport http supabase "https://mcp.supabase.com/mcp?project_ref=<your-project-ref>&read_only=true"

Open /mcp in Claude Code to authenticate.

Cursor

Add this server to your project’s MCP settings:

.cursor/mcp.json


{
  "mcpServers": {
    "supabase": {
      "url": "https://mcp.supabase.com/mcp?project_ref=<your-project-ref>&read_only=true"
    }
  }
}

Authenticate when Cursor prompts you.

Codex


codex mcp add supabase --url "https://mcp.supabase.com/mcp?project_ref=<your-project-ref>&read_only=true"
codex mcp login supabase

After connecting, ask your agent to list the project’s tables. If you need it to apply a migration, configure write access for the intended development project before starting that task.

Account and project scope

These tools use the permissions of the account you authenticate with. Scope connections to the project you are working on when the vendor supports it. For OneSignal tests, specify your test device or segment before sending.

Vendor configuration and app configuration are separate. If your agent creates an entitlement called premium in RevenueCat, it must also update the app and server entitlement settings described in function secrets. Run yarn skills:doctor to inspect configuration, then test the affected feature.
