Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.01196 |
| Opus 5 | $0.00000 | $0.00598 |
| Sonnet 5 | $0.00000 | $0.00239 |
| Haiku 4.5 | $0.00000 | $0.00120 |
Grade A, and why
mcp-integration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
集成 MCP
MCP(Model Context Protocol)让智能体调用外部服务提供的工具。管理员在“扩展 → MCP”中添加远程服务器,智能体配置再决定哪些服务器进入运行时。
支持的传输方式
| 传输方式 | 适用场景 |
|---|---|
streamable_http |
新的远程 MCP 服务 |
sse |
仍提供 SSE 接口的远程服务 |
stdio |
仅限代码维护的系统内置 MCP |
管理接口只接受 streamable_http 和 sse。Yuxi 不允许通过 HTTP 请求创建任意本地 stdio 进程;历史用户 stdio 配置会被禁用,应迁移为远程服务。
添加远程 MCP
在“扩展 → MCP”点击“添加 MCP”,填写稳定标识、名称、传输方式和 URL。例如:
{
"slug": "custom-remote-mcp",
"name": "Example MCP",
"transport": "streamable_http",
"url": "https://example.com/mcp"
}
管理接口对应:
POST /api/system/mcp-servers
Authorization: Bearer <admin-token>
Content-Type: application/json
{
"slug": "custom-remote-mcp",
"name": "Example MCP",
"transport": "streamable_http",
"url": "https://example.com/mcp",
"description": "提供示例查询工具"
}
需要认证的远程服务可以配置 HTTP headers、连接超时和 SSE 读取超时。凭证会随着连接请求发送,请只配置必要的 header,并把管理接口限制在可信的管理员范围。
添加后先点击“测试连接”,确认能发现工具,再把服务器状态设为“已添加”。状态关闭时,服务器记录仍保留,但不会进入运行时。
让智能体使用 MCP
在智能体配置的 MCP 字段中选择已添加的服务器:
- 未显式配置时,使用当前用户可见的全部已启用服务器;
- 显式选择后,只使用选择项;
- MCP 工具仍会在执行处使用当前用户身份和服务器配置;
- 管理员可以在 MCP 详情页单独禁用某个工具。
MCP 配置从 PostgreSQL 读取,工具对象按配置哈希缓存。修改连接配置或工具禁用列表后,下一次运行会使用新的配置键。
添加内置 stdio MCP
stdio MCP 等价于在 API/worker 容器内启动一个进程,只适合经过代码审查且必须本地运行的系统能力。远程服务可以承载时,优先使用 SSE 或 Streamable HTTP。
开发者在 service.py 的 _DEFAULT_MCP_SERVERS 中添加固定定义:
_DEFAULT_MCP_SERVERS = {
"example-mcp": {
"command": "npx",
"args": ["-y", "@scope/[email protected]"],
"transport": "stdio",
"description": "说明具体能力和使用场景",
"icon": "🧩",
"tags": ["内置"],
},
}
command、args 和 env 必须是代码中的固定值,包版本必须锁定;不能从 HTTP 请求、数据库字段或不受信任的环境拼接。env 只放非敏感固定值,密钥不能提交到代码或同步到数据库。
API/worker 启动时会把内置定义同步到数据库。新内置 MCP 默认未添加,管理员需要在管理页启用;内置项的连接配置由代码维护,不能删除或通过页面改成其他进程。
验证新内置 MCP:
docker compose up -d --build api worker
docker compose logs --tail=100 api worker
然后在管理页添加并测试工具。测试只确认连接和工具发现,不要在没有隔离和授权的情况下执行文件写入、Shell 或其他副作用。
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mcp-integration is an agent published in the GitHub repository xerrors/Yuxi (6,591 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,196 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
