Codex CLI 0.44.0版本支持了streamable http mcp，但是有一点需要注意

从0.44.0版本开始，在config.toml文件中很容易就能添加streamable http类型的mcp了

简单配置如下：

[mcp_servers.figma]
url = "http://127.0.0.1:3845/mcp"

如果mcp服务器需要验证，那么加上这一行就行

[mcp_servers.figma]
url = "http://127.0.0.1:3845/mcp"
bearer_token = "<token>"

但是有一点需要特别注意，由于现在还在实验阶段，需要在顶层配置中添加这条语句

experimental_use_rmcp_client = true

有些人可能不知道什么是顶层配置，包括codex的官方仓库都有人发了issue，我这里放个样例，一看就懂

model_provider = "cliproxyapi"
model = "gpt-5-codex"
disable_response_storage = true
approval_policy = "never"
sandbox_mode = "danger-full-access"
model_reasoning_effort = "high"

experimental_use_rmcp_client = true

[model_providers.cliproxyapi]
name = "cliproxyapi"
base_url = "https://AAA.BBB/v1"
wire_api = "responses"

[mcp_servers.context7]
command = "npx"
args = ["-y", "@upstash/context7-mcp"]

[mcp_servers.serena]
url = "http://127.0.0.1:9121/mcp"
