How to integrate Tpscheck MCP with Codex
Connect Codex to Tpscheck MCP. Check if this number is tps registered, verify marketing call compliance for list, and more using natural language, with authentication handled for you.
Api Key
Tpscheck is a real-time service for verifying UK phone numbers against TPS and CTPS registers. It helps prevent unwanted marketing calls and ensures compliance with UK telemarketing laws.

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.
How to install Tpscheck MCP in Codex
Run the setup command
Run this command in your terminal to add the Composio MCP server to Codex.
It will initiate the authentication in a browser window, authorize Codex to access your Composio account.
(Optional) Authenticate with OAuth
To authenticate manually, run the login command to open a browser window and authorize Codex to access your Composio account.
bash
codex mcp login composioVerify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
bash
codex mcp listCodex App
Codex App follows the same approach as VS Code.
- Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
- Fill the header and Key fields with
{ "x-consumer-api-key" = "ck_*******" }. - The Key is the Composio API key, that you can find on dashboard.composio.dev
- Click on Authenticate and authorize Codex to your Composio account and you're all set.
- Restart and verify if it's there in
.codex/config.toml
bash
[mcp_servers.composio]
url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }What is the Tpscheck MCP server, and what's possible with it?
The Tpscheck MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Tpscheck account. It provides structured and secure access to UK phone number verification services, so your agent can instantly check TPS/CTPS registration, validate numbers, determine their type, and identify providers on your behalf.
- Real-time TPS/CTPS registration checks: Instantly verify if any UK phone number is listed on the Telephone Preference Service (TPS) or Corporate TPS, ensuring compliance with marketing regulations.
- Phone number validity verification: Quickly determine if a phone number is valid and active before using it for outreach or communication purposes.
- Number type and classification detection: Identify whether a number is mobile, landline, or business, helping tailor your contact strategy accordingly.
- Location and provider lookup: Retrieve geographic and telecom provider information for any UK number to better understand and segment your contact lists.
Conclusion
You've successfully integrated Tpscheck with Codex using Composio's MCP server. Now you can interact with Tpscheck directly from your terminal, VS Code, or the Codex App using natural language commands.
Key benefits of this setup:
- Seamless integration across CLI, VS Code, and standalone app
- Natural language commands for Tpscheck operations
- Managed authentication through Composio
- Access to 20,000+ tools across 1000+ apps for cross-app workflows
- CodeAct workbench for complex tool chaining
Next steps:
- Try asking Codex to perform various Tpscheck operations
- Explore cross-app workflows by connecting more toolkits
- Build automation scripts that leverage Codex's AI capabilities

FAQ
Frequently asked questions
With a standalone Tpscheck MCP server, the agents and LLMs can only access a fixed set of Tpscheck tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Tpscheck and many other apps based on the task at hand, all through a single MCP endpoint.
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 Tpscheck tools.
Yes, absolutely. You can configure which Tpscheck 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.
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 Tpscheck data and credentials are handled as safely as possible.
