I have set up MCP servers to build a multi-agent auto building and reviewing code. I added mcp in config.toml
[mcp_servers.codex-reviewer]
type = "stdio"
command = "/opt/anaconda3/bin/python3"
args = ["/Users/asuna/.codex/scripts/codex_reviewer_mcp.py"]
env = { PATH = "/opt/anaconda3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin", HOME = "/Users/asuna", CODEX_BINARY = "/Users/asuna/.codex/bin/codex-latest", CODEX_REVIEWER_FRAMEWORK_ROOT = "/Users/asuna/Asuna/study&work/git/agentframework" }
startup_timeout_sec = 300
tool_timeout_sec = 300
but it can't be found, the jsonl file said
resources/list failed: failed to get client: MCP startup failed: timed out handshaking with MCP server after 10s
resources/templates/list failed: failed to get client: MCP startup failed: timed out handshaking with MCP server after 10s
Codex has help me recheck (the python script doesn't have any problem)and claimed that IDE Codex did not read config.toml, but i have reopened my window, even poweroff my mac, but it still failed.
Here are codex output
截至 2026-03-25 20:48 +0800,当前这个 Codex 会话不能访问 codex-reviewer。
证据很直接:
~/.codex/config.toml 里有 codex-reviewer 配置,wrapper 脚本也存在。
但当前会话没有暴露 mcp__codex_reviewer__codex、mcp__codex_reviewer__codex_reply、mcp__codex_reviewer__review_gate。
按服务器名去枚举 codex-reviewer 的 MCP 资源和模板时,都返回 MCP startup failed: timed out handshaking with MCP server after 10s。
What steps can reproduce the bug?
- Register a mcp server like the above text
What is the expected behavior?
