How to integrate NamSor MCP with Codex

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With NamSor MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.

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 NamSor MCP in Codex

Run the setup command

Run this command in your terminal to add the Composio MCP server to Codex.

Terminal

It will initiate the authentication in a browser window, authorize Codex to access your Composio account.

Composio authentication page

(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 composio

Verify the connection

Run codex mcp list to confirm Composio appears as a registered MCP server.

bash
codex mcp list

Codex App

Codex App follows the same approach as VS Code.

  1. Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
  2. Fill the header and Key fields with { "x-consumer-api-key" = "ck_*******" }.
  3. The Key is the Composio API key, that you can find on dashboard.composio.dev
  4. Click on Authenticate and authorize Codex to your Composio account and you're all set.
Codex App MCP setup
  1. 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 NamSor MCP server, and what's possible with it?

The NamSor MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your NamSor account. It provides structured and secure access to personal name classification and enrichment, so your agent can parse names, infer gender, identify likely origins, classify diaspora, and estimate residence countries on your behalf.

  • Personal name parsing: Have your agent split full personal names into likely first-name and last-name components.
  • Gender and origin classification: Let the agent infer likely gender, countries of origin, and regions of origin from first-and-last names.
  • Diaspora and residence insights: Direct your agent to classify likely diaspora or ethnicity within a known country, or estimate likely countries and regions of residence.
  • Proper noun classification: Instruct your agent to determine whether proper nouns are likely personal names, brands, places, or other supported types.
  • Account usage monitoring: Have your agent check your NamSor plan, quota, current billing-period usage, limits, and overage summary without exposing your API key.

Conclusion

You've successfully integrated NamSor with Codex using Composio's MCP server. Now you can interact with NamSor 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 NamSor 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 NamSor 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 NamSor MCP server, the agents and LLMs can only access a fixed set of NamSor tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from NamSor 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 NamSor tools.

Yes, absolutely. You can configure which NamSor 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 NamSor data and credentials are handled as safely as possible.
