type = "stdio"
command = "npx"
args = ["-y", "chrome-devtools-mcp@latest"]

[mcp_servers.context7]

First, I can confirm that my MCP configuration is correct. I tested it using different versions of Codex, up to v0.120.0, and the AI successfully retrieved the configured MCP and made proper calls. However, starting from v0.121.0 and above, while /mcp can retrieve the MCP and its associated tools, the following calls return empty results:

• Called codex.list_mcp_resources({})
└ {"resources": []}

• Called codex.list_mcp_resource_templates({})
└ {"resourceTemplates": []}

As a result, the AI fails to recognize any MCP resources.

What steps can reproduce the bug?

MCP cannot be used with versions ≥ v0.121.0.

What is the expected behavior?
