feat: introduce mcp-server crate (#792) This introduces the `mcp-server` crate, which contains a barebones MCP server that provides an `echo` tool that echoes the user's request back to them. To test it out, I launched [modelcontextprotocol/inspector](https://github.com/modelcontextprotocol/inspector) like so: ``` mcp-server$ npx @modelcontextprotocol/inspector cargo run -- ``` and opened up `http://127.0.0.1:6274` in my browser: ![image](https://github.com/user-attachments/assets/83fc55d4-25c2-4497-80cd-e9702283ff93) I also had to make a small fix to `mcp-types`, adding `#[serde(untagged)]` to a number of `enum`s.

Update cargo to 2024 edition (#842) Some effects of this change: - New formatting changes across many files. No functionality changes should occur from that. - Calls to `set_env` are considered unsafe, since this only happens in tests we wrap them in `unsafe` blocks

Workspace lints and disallow unwrap (#855) Sets submodules to use workspace lints. Added denying unwrap as a workspace level lint, which found a couple of cases where we could have propagated errors. Also manually labeled ones that were fine by my eye.

chore: introduce codex-common crate (#843) I started this PR because I wanted to share the `format_duration()` utility function in `codex-rs/exec/src/event_processor.rs` with the TUI. The question was: where to put it? `core` should have as few dependencies as possible, so moving it there would introduce a dependency on `chrono`, which seemed undesirable. `core` already had this `cli` feature to deal with a similar situation around sharing common utility functions, so I decided to: * make `core` feature-free * introduce `common` * `common` can have as many "special interest" features as it needs, each of which can declare their own deps * the first two features of common are `cli` and `elapsed` In practice, this meant updating a number of `Cargo.toml` files, replacing this line: ```toml codex-core = { path = "../core", features = ["cli"] } ``` with these: ```toml codex-core = { path = "../core" } codex-common = { path = "../common", features = ["cli"] } ``` Moving `format_duration()` into its own file gave it some "breathing room" to add a unit test, so I had Codex generate some tests and new support for durations over 1 minute.

feat: make Codex available as a tool when running it as an MCP server (#811) This PR replaces the placeholder `"echo"` tool call in the MCP server with a `"codex"` tool that calls Codex. Events such as `ExecApprovalRequest` and `ApplyPatchApprovalRequest` are not handled properly yet, but I have `approval_policy = "never"` set in my `~/.codex/config.toml` such that those codepaths are not exercised. The schema for this MPC tool is defined by a new `CodexToolCallParam` struct introduced in this PR. It is fairly similar to `ConfigOverrides`, as the param is used to help create the `Config` used to start the Codex session, though it also includes the `prompt` used to kick off the session. This PR also introduces the use of the third-party `schemars` crate to generate the JSON schema, which is verified in the `verify_codex_tool_json_schema()` unit test. Events that are dispatched during the Codex session are sent back to the MCP client as MCP notifications. This gives the client a way to monitor progress as the tool call itself may take minutes to complete depending on the complexity of the task requested by the user. In the video below, I launched the server via: ```shell mcp-server$ RUST_LOG=debug npx @modelcontextprotocol/inspector cargo run -- ``` In the video, you can see the flow of: * requesting the list of tools * choosing the **codex** tool * entering a value for **prompt** and then making the tool call Note that I left the other fields blank because when unspecified, the values in my `~/.codex/config.toml` were used: https://github.com/user-attachments/assets/1975058c-b004-43ef-8c8d-800a953b8192 Note that while using the inspector, I did run into https://github.com/modelcontextprotocol/inspector/issues/293, though the tip about ensuring I had only one instance of the **MCP Inspector** tab open in my browser seemed to fix things.
