# Telnyx MCP Apps

> Discover experimental app-specific Streamable HTTP MCP surfaces for focused Telnyx workflows.

MCP Apps are app-specific Model Context Protocol (MCP) surfaces for focused Telnyx workflows. Each app exposes a Streamable HTTP MCP endpoint with a narrower tool set than the canonical Telnyx API MCP server.

Use MCP Apps when an MCP client or scanner needs to discover focused, app-specific Telnyx tools. Use the [canonical Telnyx API MCP endpoint](/development/mcp/remote-mcp) when you need the broader Telnyx API action MCP surface at `https://api.telnyx.com/v2/mcp`.

<Callout type="info">
  MCP Apps are experimental app-specific MCP surfaces. Discover available apps from the catalog before connecting to an app endpoint.
</Callout>

## Catalog endpoint

Discover the available MCP Apps from the catalog:

```http theme={null}
GET https://api.telnyx.com/v2/mcp/apps
Authorization: Bearer <TELNYX_API_KEY>
```

The catalog requires a Telnyx API key in the `Authorization` header using Bearer authentication.

## App MCP endpoints

Each catalog entry has a slug. Connect MCP clients to an app-specific Streamable HTTP MCP endpoint with this URL pattern:

```text theme={null}
https://api.telnyx.com/v2/mcp/apps/{slug}/mcp
```

For example, the `voice-monitor` app endpoint is:

```text theme={null}
https://api.telnyx.com/v2/mcp/apps/voice-monitor/mcp
```

## Available apps

The current catalog includes:

* `number-intelligence` — **Number Intelligence**: Phone-number analysis using Telnyx Number Lookup and read-first readiness signals.
* `usage-cost-explorer` — **Usage & Cost Explorer**: Balance, usage reports, billing groups, and guarded billing controls.
* `voice-monitor` — **Voice Monitor**: Read-only active-call monitoring, call timelines, call status, and recording discovery.

## Safety notes

* MCP Apps are app-specific. The available tools and side-effect risk depend on the selected app and tool.
* Current apps are designed around read-first workflows where possible.
* Billing controls are guarded, but review tool descriptions and requested actions before approving any MCP tool call that can change account or billing state.
* These app-specific endpoints are distinct from the canonical all-API MCP endpoint at `https://api.telnyx.com/v2/mcp`.
