fix: separate `codex mcp` into `codex mcp-server` and `codex app-server` (#4471) This is a very large PR with some non-backwards-compatible changes. Historically, `codex mcp` (or `codex mcp serve`) started a JSON-RPC-ish server that had two overlapping responsibilities: - Running an MCP server, providing some basic tool calls. - Running the app server used to power experiences such as the VS Code extension. This PR aims to separate these into distinct concepts: - `codex mcp-server` for the MCP server - `codex app-server` for the "application server" Note `codex mcp` still exists because it already has its own subcommands for MCP management (`list`, `add`, etc.) The MCP logic continues to live in `codex-rs/mcp-server` whereas the refactored app server logic is in the new `codex-rs/app-server` folder. Note that most of the existing integration tests in `codex-rs/mcp-server/tests/suite` were actually for the app server, so all the tests have been moved with the exception of `codex-rs/mcp-server/tests/suite/mod.rs`. Because this is already a large diff, I tried not to change more than I had to, so `codex-rs/app-server/tests/common/mcp_process.rs` still uses the name `McpProcess` for now, but I will do some mechanical renamings to things like `AppServer` in subsequent PRs. While `mcp-server` and `app-server` share some overlapping functionality (like reading streams of JSONL and dispatching based on message types) and some differences (completely different message types), I ended up doing a bit of copypasta between the two crates, as both have somewhat similar `message_processor.rs` and `outgoing_message.rs` files for now, though I expect them to diverge more in the near future. One material change is that of the initialize handshake for `codex app-server`, as we no longer use the MCP types for that handshake. Instead, we update `codex-rs/protocol/src/mcp_protocol.rs` to add an `Initialize` variant to `ClientRequest`, which takes the `ClientInfo` object we need to update the `USER_AGENT_SUFFIX` in `codex-rs/app-server/src/message_processor.rs`. One other material change is in `codex-rs/app-server/src/codex_message_processor.rs` where I eliminated a use of the `send_event_as_notification()` method I am generally trying to deprecate (because it blindly maps an `EventMsg` into a `JSONNotification`) in favor of `send_server_notification()`, which takes a `ServerNotification`, as that is intended to be a custom enum of all notification types supported by the app server. So to make this update, I had to introduce a new variant of `ServerNotification`, `SessionConfigured`, which is a non-backwards compatible change with the old `codex mcp`, and clients will have to be updated after the next release that contains this PR. Note that `codex-rs/app-server/tests/suite/list_resume.rs` also had to be update to reflect this change. I introduced `codex-rs/utils/json-to-toml/src/lib.rs` as a small utility crate to avoid some of the copying between `mcp-server` and `app-server`.

fix: remove mcp-types from app server protocol (#4537) We continue the separation between `codex app-server` and `codex mcp-server`. In particular, we introduce a new crate, `codex-app-server-protocol`, and migrate `codex-rs/protocol/src/mcp_protocol.rs` into it, renaming it `codex-rs/app-server-protocol/src/protocol.rs`. Because `ConversationId` was defined in `mcp_protocol.rs`, we move it into its own file, `codex-rs/protocol/src/conversation_id.rs`, and because it is referenced in a ton of places, we have to touch a lot of files as part of this PR. We also decide to get away from proper JSON-RPC 2.0 semantics, so we also introduce `codex-rs/app-server-protocol/src/jsonrpc_lite.rs`, which is basically the same `JSONRPCMessage` type defined in `mcp-types` except with all of the `"jsonrpc": "2.0"` removed. Getting rid of `"jsonrpc": "2.0"` makes our serialization logic considerably simpler, as we can lean heavier on serde to serialize directly into the wire format that we use now.
