Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With the Better proposals MCP integration, Codex can track sent and signed proposals, fetch quotes and templates, create companies and proposal covers, and check your brand settings, all without leaving the terminal or the app, whichever you prefer.

How to integrate Better proposals MCP with Codex
Connect Codex to Better proposals MCP. List all proposals sent this month, create a new company profile, and more using natural language, with authentication handled for you.
Api Key
Better Proposals is a web-based tool for crafting and sending professional proposals. It helps teams impress clients and close deals faster with slick, easy-to-use templates.

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 1700+ 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 Better proposals 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_*******" }Try it
Ask Codex for a Better proposals task. The first time, Composio asks you to connect your Better proposals account.
For example, ask it to:
- "List all proposals sent this month"
- "Create a new company profile"
- "Show available proposal templates for selection"
What is the Better proposals MCP server, and what's possible with it?
The Better Proposals MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Better Proposals account. It provides structured and secure access to your proposals, quotes, companies, templates, and settings, so your agent can track proposal progress, review quotes, inspect templates, create companies, and check account settings on your behalf.
- Proposal tracking: Have your agent list proposals, count them, retrieve specific proposal details, and find proposals that are new, opened, sent, signed, or paid.
- Quote review: Instruct your agent to list available quotes and retrieve the details of a specific quote.
- Company management: Let the agent create new companies, list existing companies, and retrieve details about a specific company.
- Template and document setup: Direct your agent to inspect templates and document types, create new document types, or add proposal cover designs.
- Workspace configuration lookup: Have your agent retrieve account and brand settings, review supported currencies, and list custom merge tags.
Conclusion
You've successfully integrated Better proposals with Codex using Composio's MCP server. Now you can interact with Better proposals 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 Better proposals operations
- Managed authentication through Composio
- Access to 20,000+ tools across 1700+ apps for cross-app workflows
- CodeAct workbench for complex tool chaining
Next steps:
- Try asking Codex to perform various Better proposals 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 Better proposals MCP server, the agents and LLMs can only access a fixed set of Better proposals tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Better proposals 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 Better proposals tools.
Yes, absolutely. You can configure which Better proposals 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 Better proposals data and credentials are handled as safely as possible.
