How to Connect Dodo Payments to Codex
Query your Dodo Payments data directly from Codex using Sequel’s MCP server. Ask questions in plain English, with no SQL, no dashboards, and no context switching.
Short answer
Connect Dodo Payments to Sequel, then add Sequel's MCP server to Codex using the config on this page. Codex can then query your live Dodo Payments data in plain English, with no connector code and no CSV exports. Both steps take a few minutes.
Everything you can ask Codex about your Dodo Payments data.
Ask in plain English — Sequel translates it into a Dodo Payments query, runs it, and Codex hands back the answer. No SQL, no dashboards, no CSV exports.
- What was our total revenue last month, by currency?
- How many active subscriptions do we have and how many are set to cancel at the next billing date?
- Show payments that failed this week with their error codes.
- Which products drove the most revenue this quarter?
- List refunds in the last 30 days and the reason for each.
How it works
Three steps to get started
Connect Dodo Payments to Sequel
In your Sequel dashboard, go to Connections and add Dodo Payments. Sequel handles authentication and schema discovery automatically.
Add Sequel to the agent
Copy the Sequel MCP configuration into Codex's settings file (shown below). Swap in your API key from Settings → API Keys.
Ask Codex about your data
Restart Codex and start asking questions. "What was our total revenue last month, by currency?" — and get a real answer backed by live Dodo Payments data.
Why Codex
What Codex does with your Dodo Payments data
Grounded answers from real data
Codex with Sequel queries your actual databases before generating code or explanations. Every schema reference, column name, and data shape is verified against what's really there.
Terminal-native data access
No context switching — Codex can pull database data mid-session to inform code generation, write migrations based on actual schemas, and validate assumptions without leaving the terminal.
Agentic data workflows
Codex's multi-step agent can chain Sequel tool calls together: discover schema, sample data, run analysis, then generate code — all in one automated flow.
Configuration
Add Sequel to Codex
Place this in ~/.codex/config.yaml and replace sql_your_api_key with a key from Settings → API Keys.
~/.codex/config.yaml
mcp_servers:
sequel:
type: http
url: https://api.sequel.sh/mcp
headers:
Authorization: "Bearer sql_your_api_key"Install
Install Dodo Payments MCP in Codex
Pick your app and Sequel installs itself: a one-click link where the client supports it, that client’s own few steps where it doesn’t. Every route signs in with your Sequel account over OAuth, so there is no API key to copy and nothing to keep in sync.
Already have an MCP client?
https://api.sequel.sh/mcp
Add it as a remote (streamable HTTP) server and sign in when prompted. Skills come with it; nothing else to install. Manual setup per client
Add Sequel to Codex
Terminal
codex mcp add sequel --url https://api.sequel.sh/mcp
- 1Run the command in your terminal. It writes the server to ~/.codex/config.toml.
- 2Run codex mcp login sequel and sign in in the browser.
- 3Start Codex and ask a question.

Frequently asked questions
How do I connect Dodo Payments to Codex?
You need two things: (1) connect Dodo Payments to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to Codex using the setup shown above. Once both are done, Codex can query your Dodo Payments data directly.
What Dodo Payments data can Codex access?
Codex can access any data available through your Dodo Payments connection in Sequel. Use Sequel's search tool to discover available metrics and dimensions, then execute queries to pull the data you need.
Is my Dodo Payments data sent to Codex's servers?
Query results are returned to Codex as context within your conversation. Only the data you explicitly ask about is retrieved. Sequel never stores your query results permanently — they exist only for the duration of the tool call.
Do I need a Sequel account?
Yes. You need a Sequel account to connect Dodo Payments and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to Dodo Payments and generate an API key from Settings → API Keys.
Can I connect multiple Dodo Payments accounts?
Yes. Sequel supports multiple connections of the same type. If you have multiple Dodo Payments accounts or properties, add each as a separate connection in Sequel. Codex will be able to query all of them.
How do I configure Sequel for Codex CLI?
Add the Sequel MCP server to ~/.codex/config.yaml as shown above. Create the file if it doesn't exist. Replace `sql_your_api_key` with a real key from Settings → API Keys, then restart Codex.
Does Codex CLI support HTTP MCP servers?
Yes. Codex CLI supports MCP over HTTP (Streamable HTTP transport). The `type: http` field in the config tells Codex to use this transport when connecting to Sequel.
Can I limit which databases Codex can access?
Sequel MCP is scoped to your organization's connected data sources. You can create separate API keys for different environments and revoke them at any time from Settings → API Keys.
Is this the same as the original OpenAI Codex model?
No — Codex CLI is OpenAI's agentic terminal coding tool, separate from the original Codex language model. It uses the latest OpenAI models (GPT-4o and o-series) with MCP tool support.
How do I connect Dodo Payments to Sequel?
In the Dodo Payments dashboard go to Developer → API Keys, add a key with 'Enable write access' unchecked, and paste it into Sequel. Pick 'test' if the key was created in test mode. That's it; no OAuth and nothing to install.
Can Sequel change anything in my Dodo Payments account?
No. Sequel only calls list and read endpoints, and we recommend a read-only key so the credential itself cannot create refunds, products or subscriptions.
Are amounts in dollars or cents?
Dodo Payments returns every amount in the currency's smallest unit (cents for USD, yen for JPY). Sequel's agent knows this and divides before reporting, and never sums across currencies without saying so.
Does it work with test mode?
Yes. Test mode is a separate environment with its own keys; choose 'test' when connecting and Sequel will query test.dodopayments.com instead of live.
