Connect OpenAI Codex to a Webex MCP server.

anchorToken-based (WCIT)

Codex supports MCP elicitation, so you can authenticate with a WCIT token. Additional OAuth scopes required by specific tools are requested at runtime during tool calls — no integration setup needed.

Generate WCIT Token

Generate a WCIT token to connect using token-based authentication. The WCIT is issued with only the spark:mcp scope, which allows you to connect to the MCP server. Additional scopes required by specific tools are requested at runtime via MCP elicitation during tool calls.

Generate Token

Add the MCP server configuration

Open or create your Codex configuration file at ~/.codex/config.toml. Add an entry for the Webex MCP server:

[mcp_servers.YOUR_MCP_SERVER_NAME]
enabled = true
url = "YOUR_MCP_SERVER_URL"
http_headers = {"Authorization" = "Bearer YOUR_TOKEN"}

Replace YOUR_TOKEN with your WCIT token.
