📝 WalkthroughWalkthroughAdds and registers an async Qwen Code CLI provider. The provider discovers executables, manages persistent state, configures MCP, probes authentication, streams JSON events, resumes sessions, handles timeouts and cancellation, and documents setup and operation. ChangesQwen Code provider integration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The new Qwen Code bot can expose tools beyond a turn’s requested allowlist, continue after MCP setup fails, block other bot work during setup, leak timed-out processes, and show duplicate responses. These concrete security, reliability, and user-facing issues make the PR unsafe to merge until they are fixed or explicitly accepted by the owner. Sequence Diagram(s)sequenceDiagram

In `@bot/qwen_code.py`:
- Around line 223-233: Update the version-probe exception handling around
proc.communicate in the relevant probe method so that an asyncio.TimeoutError
terminates proc and awaits proc.wait() before caching and returning the
unavailable ProviderStatus; preserve the existing handling for OSError and the
normal successful probe path.
- Around line 281-285: Update QwenCodeProvider’s per-turn execution flow around
_ensure_mcp_configured and argv construction to enforce turn.allowed_tools for
every turn, including when persistent MCP configuration enables all tools. Apply
the allowlist through an isolated per-turn or process-scoped mechanism that
cannot leak across concurrent turns, while preserving existing resume-token
handling.
- Around line 263-269: The _ensure_mcp_configured flow must check the qwen mcp
add subprocess result, return its setup error to the turn when the command
fails, and log successful registration only on a successful exit; retain
automatic HTTP/HTTPS detection without adding a transport flag. In
bot/qwen_code.py lines 263-269, update the subprocess handling accordingly. In
docs/qwen-code-bot.md lines 172-175, update the documentation to reflect that
registration failures are returned before the turn and success is logged only
after successful registration.
- Around line 253-268: Update _ensure_mcp_configured and its caller send so the
two MCP subprocess operations no longer block the event loop; use asynchronous
subprocess execution with timeout handling or dispatch the existing blocking
work to a worker thread, while preserving the current already-configured check
and MCP add behavior.
- Around line 277-280: Update the argument construction around argv to include
--include-partial-messages, then adjust the response processing to track
content_block_delta output and suppress matching final assistant text blocks.
Preserve normal final-text handling when no matching partial content was
emitted.
In `@docs/qwen-code-bot.md`:
- Line 9: Specify fenced-code languages in the documentation: mark the
architecture diagram fence as text and the JSONL example fence as json,
resolving both MD040 warnings.

Move MCP setup off the event loop.
send() calls synchronous _ensure_mcp_configured() before starting the Qwen process. Two sequential subprocess.run() calls can block the event loop for up to 20 seconds. Use asyncio.create_subprocess_exec() with asyncio.wait_for(), or run the blocking calls in a worker thread.

Qwen Code official documentation qwen mcp add --transport default stdio HTTP
💡 Result:
The default transport for the qwen mcp add command is stdio [1][2][3]. However, the command includes an auto-detection feature that influences how the transport is determined [4][5]: * Auto-Detection: If the [commandOrUrl] argument starts with http:// or https://, the system automatically selects the http transport, even if the --transport flag is not explicitly provided [4][5]. * Explicit Flag: If you provide the --transport flag (e.g., --transport http, --transport sse, or --transport stdio), it will override the automatic detection [4]. In summary, while the CLI documentation identifies stdio as the default [2][3], the command is designed to intelligently switch to http when a URL is detected [4][5].

Handle failed MCP registration before starting the turn. qwen mcp add auto-detects HTTP for an http:// or https:// URL, so the transport flag is not required. However, _ensure_mcp_configured ignores the add command's exit status and logs success after failure. Return the setup error to the turn and log success only when the command exits successfully.

Qwen Code headless stream-json --include-partial-messages content_block_delta assistant output format documentation
💡 Result:
In Qwen Code, headless mode with --output-format stream-json is designed for real-time monitoring of agent execution, outputting line-delimited JSON objects [1][2][3]. When --include-partial-messages is enabled, the CLI emits additional incremental events, including content_block_delta, to facilitate real-time UI updates [1][2][3]. The content_block_delta event structure for partial assistant messages is as follows [4][5]: { "type": "content_block_delta", "index": number, "delta": { "type": "text_delta" | "thinking_delta" | "input_json_delta", // Field depends on the type: // "text": string (for text_delta) // "thinking": string (for thinking_delta) // "partial_json": string (for input_json_delta) } } The parentToolUseId is also tracked for these events to differentiate between the main agent and subagents [4]. Beyond the delta events, other partial message stream events include message_start, content_block_start, content_block_stop, and message_stop [2][5]. This stream-json output ensures that incremental progress, such as thinking processes or tool call arguments, is visible before the final message is complete [4][6]. Usage example: qwen -p "Write a Python script" --output-format stream-json --include-partial-messages [1][2]

Qwen Code stream-json include-partial-messages final assistant event duplicate text output
💡 Result:
In Qwen Code, the --include-partial-messages flag is used in conjunction with --output-format stream-json to emit real-time stream events—such as message_start, content_block_delta, and message_stop—for UI updates and monitoring [1][2]. Regarding duplicate text output or event issues, Qwen Code has addressed several causes of duplication through specific updates: 1. Stream Retries: Previously, retries on failed streaming attempts could result in duplicated output because the UI did not discard content from the failed attempt. PR #1704 introduced a fix to track and remove streamed history items when a retry occurs, preventing these duplicates [3][4]. 2. Tool Call Results: Duplicate tool call results in the UI were linked to improper handling of stream chunks (specifically when finishReason and usageMetadata arrived in separate chunks), causing the system to incorrectly re-yield responses. A fix involving a finishYielded flag was implemented to ensure that once a merged finish response is yielded, subsequent trailing chunks do not trigger duplicate tool executions [5]. 3. Provider Replay: Some OpenAI-compatible providers may re-emit tool-call IDs that have already been handled. While Qwen Code suppresses re-execution of these tools, the internal logic for creating responses can sometimes synthesize and re-send redundant tool responses back to the provider, leading to recursive loops in specific configurations [6]. For developers encountering duplicate output, it is recommended to ensure the environment is updated to a version containing these fixes (e.g., post-February/March 2026) and, for headless runs, to utilize safety limits like --max-session-turns or --max-tool-calls to prevent loops from cumulative or deterministic providers [7][6].

Qwen Code official documentation MCP includeTools excludeTools tool filtering configuration scope
💡 Result:
In Qwen Code, tool filtering for Model Context Protocol (MCP) servers is managed using the includeTools and excludeTools configuration options [1][2]. These settings allow you to control exactly which tools are exposed to the model from a specific MCP server [1][3]. Configuration Scope and Behavior The includeTools and excludeTools options are defined within the mcpServers object in your configuration (e.g., settings.json) [1][4]. includeTools: A whitelist of tool names to include [1][2]. If specified, only the tools listed here will be available [3][4]. If not specified, all tools provided by the server are enabled by default [1][3]. excludeTools: A blacklist of tool names to exclude [1][2]. Tools listed here will not be available to the model, even if they are exposed by the MCP server [2][3]. Precedence: The excludeTools list takes precedence over includeTools [1][2]. If a tool name is present in both lists, it will be excluded [2][3]. Example Configuration You can filter tools for a specific MCP server as shown below: { "mcpServers": { "my_server": { "command": "python", "args": ["-m", "my_mcp_server"], "includeTools": ["safe_tool", "data_processor"], "excludeTools": ["dangerous_tool"] } } } In addition to per-server tool filtering, Qwen Code also supports global MCP server management through the mcp.allowed and mcp.excluded lists in your settings [1][4]. These allow you to enable or disable entire MCP servers based on exact names or glob patterns (e.g., "puppeteer") [1][4]. When a server matches both global lists, the mcp.excluded list takes precedence [1][4].

💡 Result:
In Qwen Code, includeTools and excludeTools are used to filter which tools are exposed by an MCP server to the model [1][2]. These settings can be configured either by directly editing your settings.json file or by using the qwen mcp CLI [1][3]. Configuration Logic: - includeTools: Defines an allowlist. If specified, only the tools listed here will be available [1][2]. If omitted, all tools provided by the server are enabled by default [1][2]. - excludeTools: Defines a denylist. Tools listed here are blocked from being used, even if they are otherwise exposed by the server [1][2]. - Precedence: excludeTools takes precedence over includeTools. If a tool is present in both lists, it will be excluded [1][2][4]. Using CLI (qwen mcp add): You can apply these filters when adding a server using the --include-tools and --exclude-tools flags [1][2][3]. Both flags accept a comma-separated list of tool names [1][3]. Example: qwen mcp add my-server python -m my_mcp_server --include-tools tool_a,tool_b --exclude-tools tool_c Configuration via settings.json: You can also manually add these fields to the server entry in your settings.json [1][2]: { "mcpServers": { "my-server": { "command": "python", "args": ["-m", "my_mcp_server"], "includeTools": ["tool_a", "tool_b"], "excludeTools": ["tool_c"] } } }

Enforce turn.allowed_tools for each turn.
TurnRequest.allowed_tools is passed by the API but ignored by QwenCodeProvider. Qwen Code enables all MCP tools when includeTools and excludeTools are absent. The persistent qwen mcp add configuration therefore does not enforce a turn-specific allowlist. Use an isolated per-turn configuration or another process-scoped mechanism that applies the allowlist without cross-turn races.

* feat: Qwen Code bot provider (ported from #316) * rework: harden the Qwen Code provider and share the CLI turn core The ported provider gains the isolation and correctness the Claude provider already had. Tool lockdown: instead of a bare CLI with its full built-in toolset, turns run against a project-scoped .qwen/settings.json inside the bot's working directory — ComfyTV MCP server only (httpUrl transport, trusted), allowMCPServers pinned, every built-in shell/file/web tool excluded — written by a plain file write, replacing the `qwen mcp add` subprocess that polluted the user's global config, blocked the event loop, and registered the HTTP endpoint without a transport. Both providers now share bot/_cli_common.py (stream parser, spawn env, kill-tree, and the activity-based turn loop with 10-minute idle and 4h hard caps), so Qwen doesn't reintroduce the 30-minute turn cutoff and future fixes land once. The Qwen parser streams assistant text blocks as deltas but suppresses them once real stream deltas appear, guarding against doubled text across CLI versions. ProviderCaps grows an attachments flag: Qwen declares no attachment support, the send endpoint rejects attachments for such providers, and the composer hides its attach controls for their chats. With two providers available the ➕ button now asks which engine a new chat should use. Docs fold the standalone Chinese write-up into the bot guide (both languages, provider table + isolation notes). Needs a live check on a machine with qwen installed: settings-file tool exclusion names, -y approval flag, --resume, and the HTTP MCP transport key are implemented against qwen-code documentation. * fix: slim qwen MCP toolset to core loop and raise LLM request timeout * feat: Codex bot provider and MCP resource bridge (ported from #319) * rework: harden the Codex provider and drop the resource bridge * fix: codex headless MCP approvals via auto_review reviewer + AGENTS.md orientation --------- Co-authored-by: MuAIGC <yiyiyi676767@163.com> Co-authored-by: Pengjingyu1992 <pjy262443031@gmail.com>
