Codex

Codex supports Streamable HTTP MCP servers in ~/.codex/config.toml. The same configuration is shared by the Codex CLI and IDE extension.

Use the full MCP URL from Setup:

https://mcp.vrplatform.app/?api_key=<api-token>

Add &team_id=<team-id> only if you want a default team for the session.

CLI Setup

Add the server with the Codex CLI:

codex mcp add vrt --url "https://mcp.vrplatform.app/?api_key=<api-token>"

Start Codex and run /mcp to confirm that the vrt server connected.

Config File Setup

You can also edit ~/.codex/config.toml directly:

[mcp_servers.vrt]
url = "https://mcp.vrplatform.app/?api_key=<api-token>"
default_tools_approval_mode = "prompt"
tool_timeout_sec = 60

Read-Only Setup

For read-only Codex workflows, disable the mutation tool:

[mcp_servers.vrt]
url = "https://mcp.vrplatform.app/?api_key=<api-token>"
default_tools_approval_mode = "prompt"
disabled_tools = ["vrt_api_mutation"]
tool_timeout_sec = 60

This keeps documentation search, team lookup, OpenAPI resources, and API reads available while preventing write-capable MCP calls.
