And MCP makes the experience even better. With Teltel MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Teltel with - [OpenAI Agents SDK](https://composio.dev/toolkits/teltel/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/teltel/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/teltel/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/teltel/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/teltel/framework/openclaw) - [Hermes](https://composio.dev/toolkits/teltel/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/teltel/framework/cli) - [Google ADK](https://composio.dev/toolkits/teltel/framework/google-adk) - [LangChain](https://composio.dev/toolkits/teltel/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/teltel/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/teltel/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/teltel/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/teltel/framework/crew-ai) ## TL;DR ### Why use Composio? Apart from a managed and hosted MCP server, you will get: - CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool responses: Handle them to minimise context rot. - Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need. ## Connect Teltel to Codex ### How to install Teltel MCP in Codex ### Run the setup command Run this command in your terminal to add the Composio MCP server to Codex. ```bash codex mcp add composio --url https://connect.composio.dev/mcp ``` ## What is the Teltel MCP server, and what's possible with it? The Teltel MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Teltel account. It provides structured and secure access to your telecom data, so your agent can retrieve call logs, manage SMS messages, access user records, and handle inbound SMS events automatically. - Comprehensive call log retrieval: Quickly fetch and filter detailed lists of your recent and historical calls, including duration, status, and time for easy reporting or analysis. - SMS message management: Effortlessly access sent and received SMS logs, filter messages by sender, recipient, status, or date, and keep your communications organized. - User directory synchronization: Retrieve up-to-date lists of all users in your Teltel account, making it simple to manage contact center agents or team members. - Automated inbound SMS handling: Set up your agent to receive and process incoming SMS via webhook, so you never miss an important customer message or support request. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `TELTEL_CREATE_AUTODIALER_CUSTOM_STATUS` | Create Autodialer Custom Status | Tool to create a custom status for autodialer contacts.

With a standalone Teltel MCP server, the agents and LLMs can only access a fixed set of Teltel tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Teltel and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Codex? Yes, you can. Codex fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Teltel tools. ### Can I manage the permissions and scopes for Teltel while using Tool Router? Yes, absolutely. You can configure which Teltel scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Teltel data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
