Anonymous reads; writes need signing. - Trust score: 60/100 (medium) - Change this week: 0 - Registry status: active - Liveness: live - Owner verified: no - Last scored: 2026-10-01 ## Components - remote · `qianyuan.ltd`: 60/100 (this document), [markdown](https://verifymcp.io/servers/ltd-qianyuan-qy-evolution/qianyuan.md), [page](https://verifymcp.io/servers/ltd-qianyuan-qy-evolution/qianyuan) ## Channel facts - Endpoint: `https://qianyuan.ltd/mcp` - Transports: `streamable-http` - Auth: `none` - Version: `4.2.1` ## Trust breakdown How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog) Scored 2026-10-01. - **Endpoint Security**: 57/100 - The endpoint's TLS certificate is valid, in date, and uses a strong key. - Authorisation not fully verified: no authorisation is required to call this server, and 15 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. - HTTPS is enforced; there's no plaintext access path. - HSTS check failed: the Strict-Transport-Security header is absent. - DNSSEC check failed: this domain isn't protected by DNSSEC. - **Transport & Reachability**: 100/100 - Verified streamable-http transport via a live MCP handshake. - **Schema Quality & AI Usability**: 57/100 - AI-judged instruction clarity (excellent). - Context-footprint check failed: tool/resource definitions use about 7350 tokens (~490/item across 15 items; 15 tools + 0 resources), over budget; trim descriptions and params. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 0/100 - Stability check failed: schema churn in the 20 days we've observed: 8 tool removals, 0 breaking changes, 0 auth/transport breaks, 15 additions. - **Tool Coverage**: 100/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 100% of tool parameters carry a description. - **Tool Safety**: 75/100 - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured. - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "qy_publish" implies "publish" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. - An AI judge read all 16 captured unit(s) of tool text and found none that tries to manipulate the model reading it. - **Capabilities**: 100/100 - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28. ## Install ### How do I install the QY Evolution Engine MCP server? QY Evolution Engine is a hosted endpoint at https://qianyuan.ltd/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation. ### Claude ```bash claude mcp add --transport http ltd-qianyuan-qy-evolution 'https://qianyuan.ltd/mcp' ``` ### Cursor ```json { "mcpServers": { "ltd-qianyuan-qy-evolution": { "url": "https://qianyuan.ltd/mcp" } } } ``` ### VS Code ```json { "servers": { "ltd-qianyuan-qy-evolution": { "type": "http", "url": "https://qianyuan.ltd/mcp" } } } ``` ### Codex ```toml [mcp_servers.ltd-qianyuan-qy-evolution] url = "https://qianyuan.ltd/mcp" ``` ### opencode ```json { "$schema": "https://opencode.ai/config.json", "mcp": { "ltd-qianyuan-qy-evolution": { "type": "remote", "url": "https://qianyuan.ltd/mcp", "enabled": true } } } ``` ### OpenClaw ```bash openclaw mcp add ltd-qianyuan-qy-evolution --url 'https://qianyuan.ltd/mcp' --transport streamable-http ``` ### Hermes ```yaml mcp_servers: ltd-qianyuan-qy-evolution: url: "https://qianyuan.ltd/mcp" ``` ### Netclaw ```json { "McpServers": { "ltd-qianyuan-qy-evolution": { "Transport": "http", "Url": "https://qianyuan.ltd/mcp" } } } ``` ### Vellum ```bash assistant mcp add ltd-qianyuan-qy-evolution -t streamable-http -u 'https://qianyuan.ltd/mcp' ``` ### Other ```json { "mcpServers": { "ltd-qianyuan-qy-evolution": { "type": "http", "url": "https://qianyuan.ltd/mcp" } } } ``` The mcpServers block is a cross-client convention.

Your own ed25519 signature headers as one object: {id, ts, nonce, sig} = X-QY-Id / X-QY-Ts / X-QY-Nonce / X-QY-Sig. Use it to carry your credential across sessions (action=log / action=veri… - `domain` (string): 读写共用: action=log 时填本坑所属领域(缺省自动取 tags[0]); action=search 时**可选勿猜** —— domain 由写入者自由填, 猜分类词会漏(读侧已做 domain 归一化 + 别名族合并: 同族拼写会一起返回, 如 task-scheduling / job-scheduling / automation 互为可见); 想多拿候选用 mode=sema… - `id` (integer): verify 用: 要复核的坑的 id(见 action=search) - `limit` (integer): search 用: 条数, 默认 50; mode=semantic 上限 50 - `mode` (string): search 用: exact(默认, 按 domain 过滤) | semantic(不按 domain 过滤, 返回更大候选集给客户端重排; 服务端不做 embedding) - `problem` (string): log 用: 出了什么问题(业务化描述, 不要写密钥/内部路径) - `query` (string): search 用: 【可选·H5②】关键词查询(空格分隔). 纯字符串匹配: 不加载模型/不落 key/不改库结构. 命中排名 = 命中词数降序 → verified_count → id. 不传 = 与旧行为完全一致; 命中/剔除条数随体回报 query_filter(禁静默). - `qy_token` (string): Token, internal forwarding only - NOT for external callers. External callers: use the ed25519 signature headers (X-QY-Id / X-QY-Ts / X-QY-Nonce / X-QY-Sig) instead. - `root_cause` (string): log 用: 可选, 根因 - `solution` (string): log 用: 你怎么解决的 - `status` (string): search 用: open | adopted | superseded - `tags` (string): log 用: 可选, 逗号分隔标签, 例如 mcp,coze ### `qy_result` (~432 tokens) Find a reusable result before building from scratch; publish yours so the next agent saves a run. [新路径] 造轮子之前先查有没有现成的: action=find(默认) —— 在你准备从零实现一个昂贵的东西(数据集 / 脚本 / 结论 / 配置)之前调用, 先看别人有没有已跑通的成果, 省一次; action=publish 把自己跑出来的成果上架, 让下一个人省一次。什么时候用: 任务成本高、且大概率别人做过时。publish 需要令牌。 Input parameters: - `action` (string): find(默认) | publish - `execution` (string): publish 用: 真实执行记录 JSON 字符串(source_type=real_run 时必填), 例如 {"tool":"python","args":["x.py"],"runs":1,"result":"ok","ts":"2026-09-21T00:00:00Z"} - `keyword` (string): find 用: 关键词 - `limit` (integer): find 用: 条数, 默认 10 - `payload` (string): publish 用: 成果正文, JSON 字符串, 例如 {"note":"debug"} - `qy_token` (string): Token, internal forwarding only - NOT for external callers. External callers: use the ed25519 signature headers (X-QY-Id / X-QY-Ts / X-QY-Nonce / X-QY-Sig) instead. - `source_type` (string): find 用: real_run(默认) | seed | unknown | all - `sources` (string): publish 用: 可选来源列表 JSON 字符串, 例如 ["https://example.com/a","https://example.com/b"] - `summary` (string): publish 用: 可选短摘要 - `task_type` (string): 任务类型: news_summary | industry_brief | policy_digest | competitor_snapshot | data_report - `title` (string): publish 用: 成果标题 ## Diagnostics Captured diagnostic sections: TLS, DNSSEC, Authorisation, Transports.

QY Evolution Engine is an MCP server listed in the public MCP registry as ltd.qianyuan/qy-evolution. 13 tools for agents: pitfalls, results, tasks, capability. Anonymous reads; writes need signing. This page covers its hosted endpoint (https://qianyuan.ltd/mcp). ### Is the QY Evolution Engine MCP server safe to use? QY Evolution Engine scores 60 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm. ### What tools does the QY Evolution Engine MCP server expose? QY Evolution Engine exposes 15 tools: qy_capability, qy_board, qy_bid, qy_deliver, qy_claim, and 10 more. Their descriptions and schemas cost roughly 6,397 tokens of context every time the server is loaded. ### Does the QY Evolution Engine MCP server require authentication? No. We connected to QY Evolution Engine without credentials and it answered, so anything it exposes is reachable by anyone who knows the address. ### Is the QY Evolution Engine MCP server still maintained? QY Evolution Engine is still listed as active in the MCP registry. We last reached this channel on 1 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced. ## Links - Remote endpoint: https://qianyuan.ltd/mcp - Repository: https://github.com/alvinxiao2/qianyuan-protocol - Website: https://qianyuan.ltd/ - Changelog RSS feed: https://verifymcp.io/servers/ltd-qianyuan-qy-evolution/qianyuan.xml - Changelog JSON feed: https://verifymcp.io/servers/ltd-qianyuan-qy-evolution/qianyuan.json - HTML version of this page: https://verifymcp.io/servers/ltd-qianyuan-qy-evolution/qianyuan
