展示HN：PolyMCP技能 – 基于MCP的AI代理的可扩展工具组织
大家好，
我在PolyMCP中添加了一个技能系统，以解决大规模MCP服务器常见的问题。
当工具数量增加时：
- 代理在加载原始模式时消耗令牌
- 工具发现变得嘈杂
- 不同的代理需要不同子集的工具
- 编排逻辑泄漏到提示中
技能是经过整理的、结构化的MCP工具集，并附有文档。代理只加载它们所需的技能，而不是完整的工具模式。
技能是通过从MCP服务器发现工具并自动分类生成的。
示例：从Playwright MCP服务器生成技能：
```
polymcp skills generate --servers "npx @playwright/mcp@latest"
```
HTTP MCP服务器：
```
polymcp skills generate \
--servers "http://localhost:8000/mcp" \
--output ./mcp_skills
```
标准输入MCP服务器：
```
polymcp skills generate \
--stdio \
--servers "npx -y @playwright/mcp@latest" \
--output ./mcp_skills
```
在代理中启用技能：
```python
agent = UnifiedPolyAgent(
llm_provider=llm,
skills_enabled=True,
skills_dir="./mcp_skills",
)
```
好处：
- 更小的代理上下文
- 可扩展到大型工具集
- 代理之间可重用的能力
- 工具访问控制无需更改提示
- 适用于HTTP和标准输入MCP服务器

Hi everyone,
I added a skills system to PolyMCP to solve a common issue with MCP servers at scale.<p>When the number of tools grows:
• Agents burn tokens loading raw schemas
• Tool discovery becomes noisy
• Different agents need different subsets of tools
• Orchestration logic leaks into prompts<p>Skills are curated, structured sets of MCP tools with documentation.
Agents load only the skills they need instead of full tool schemas.<p>Skills are generated by discovering tools from MCP servers and auto-categorizing them.<p>Example: generate skills from a Playwright MCP server:<p>polymcp skills generate --servers "npx @playwright/mcp@latest"<p>HTTP MCP servers:<p>polymcp skills generate \
--servers "http://localhost:8000/mcp" \
--output ./mcp_skills<p>Stdio MCP servers:<p>polymcp skills generate \
--stdio \
--servers "npx -y @playwright/mcp@latest" \
--output ./mcp_skills<p>Enable skills in an agent:<p>agent = UnifiedPolyAgent(
llm_provider=llm,
skills_enabled=True,
skills_dir="./mcp_skills",
)<p>Benefits:
• Smaller agent context
• Scales to large tool sets
• Reusable capabilities across agents
• Tool access control without prompt changes
• Works with HTTP and stdio MCP servers<p>Repo: <a href="https://github.com/poly-mcp/Polymcp" rel="nofollow">https://github.com/poly-mcp/Polymcp</a>
