## Summary
This PR extends the existing managed `mcp_servers` identity requirement
so that one name-qualified rule can use either:
- the released exact command or URL identity;
- an exact stdio executable with an exact-length, ordered argument
matcher list; or
- a direct MCP URL matcher.
Matcher-based rules stay under the released `identity` key and use the
same `McpServerRequirement` abstraction and `mcp_servers.<server_name>`
namespace.
## Behavior
Policy activation and name qualification are unchanged:
- If `mcp_servers` is absent, ordinary configured MCP servers remain
unrestricted.
- If `mcp_servers` is present, a server needs a matching same-name
requirement.
- `mcp_servers = {}` continues to deny every configured MCP server.
- Existing exact identity requirements keep their released semantics.
Plugin-bundled MCP servers use the same requirement shapes under
`plugins.<plugin_name>.mcp_servers.<server_name>`. Top-level non-empty
rules continue to govern only ordinary configured servers; plugin rules
remain explicitly plugin-scoped. The existing globally empty
`mcp_servers = {}` plugin kill switch is preserved.
Requirements layers continue to use the existing regular TOML merge
behavior. Atomic replacement of named MCP requirements is intentionally
out of scope here and is tracked independently in #30118.
## Requirement contract
The released exact identity contract remains valid:
```toml
[mcp_servers.docs.identity]
command = "codex-mcp"
[mcp_servers.remote.identity]
url = "https://example.com/mcp"
```
Command identities continue to check only `command`; they do not inspect
arguments, `cwd`, `env`, or `env_vars`.
A command matcher uses an exact executable plus an exact-length, ordered
argument list. Each argument position supports `exact`, `prefix`, or
full-value `regex` matching:
```toml
[mcp_servers.internal_mcp_proxy.identity]
command = { executable = "company-cli", args = [
{ match = "exact", value = "mcp" },
{ match = "exact", value = "proxy" },
{ match = "exact", value = "--server" },
{ match = "regex", expression = '^https://[A-Za-z0-9-]+\.mcp\.internal\.example\.com(?::443)?(?:/.*)?$' },
] }
```
Direct streamable HTTP MCP definitions can use the same value matcher
types through `identity.url`:
```toml
[mcp_servers.internal_http.identity]
url = {
match = "regex",
expression = '^https://[A-Za-z0-9-]+\.mcp\.internal\.example\.com(?:/.*)?$',
}
```
Plugin-bundled MCP matchers use the same contract inside the
plugin-qualified allowlist:
```toml
[plugins."sample@test".mcp_servers.internal_mcp_proxy.identity]
command = { executable = "company-cli", args = [
{ match = "exact", value = "mcp" },
{ match = "exact", value = "proxy" },
] }
```
Regexes are validated while managed requirements are loaded, and regex
matching must cover the complete value. Command matchers constrain only
the executable and arguments.
## Why
Enterprise administrators need to allow MCP servers by executable and
positional-argument shape, including fixed arguments plus constrained
values such as internal MCP URLs passed to a proxy.
## Validation
- `just fmt`
- `git diff --check`
- `just test -p codex-config` (198 passed)
- `just test -p codex-core mcp_servers_by_matchers --lib` (2 passed)

Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
Using Codex with your ChatGPT plan
