Codex MCP: give Codex paid tools

Add o11 to the Codex CLI as a remote MCP server. Codex can then find, price, and call paid tools from one wallet with a spending limit.

    Ask your agent to find a search tool, show its price, and check your balance without running it.

Questions

What is the o11 MCP server URL for Codex?
https://go.o11.ai/mcp. It is a remote HTTP MCP server. Codex signs in through your browser, and you choose which wallet and card it may use.
Which tools can Codex use through o11?
Every tool in the o11 catalog, including web search (Exa, Tavily, Brave Search, Perplexity), scraping (Firecrawl, Apify), SEO data (DataForSEO), people data (Apollo, Hunter), and voice and video generation.
How does Codex pay for tools?
Each call is paid from your o11 wallet. o11 quotes the price before a call runs, and the card’s allowance caps what Codex can spend. You can change or revoke access at any time.
Do I need separate accounts for each provider?
No for most tools. o11 calls them on its own accounts and charges your wallet per call. You can also connect your own provider accounts where supported.
