MCP CLI

Use

scripts/mcp.py

from this skill. The calling skill owns the endpoint, transport, tool choice, and investigation workflow.

bash

python3 "$HOME/.agents/skills/mcp-cli/scripts/mcp.py" --transport streamable-http --url "https://approved.kraken.zone/mcp" tools
python3 "$HOME/.agents/skills/mcp-cli/scripts/mcp.py" --transport streamable-http --url "https://approved.kraken.zone/mcp" describe tool_name
python3 "$HOME/.agents/skills/mcp-cli/scripts/mcp.py" --transport streamable-http --url "https://approved.kraken.zone/mcp" call tool_name --args '{"key":"value"}'

Pass credentials by environment-variable reference, never by value:

bash

python3 "$HOME/.agents/skills/mcp-cli/scripts/mcp.py" --transport streamable-http --url "https://mcp.linearb.io/mcp" --header-env "x-api-key=LINEARB_API_KEY" tools

Run with full network access, outside the sandbox; internal endpoints require VPN. Retry one network or certificate failure outside the sandbox before reporting a blocker.

Use only an endpoint fixed by a trusted calling skill.

tools

returns names only;

describe

loads one schema;

call

exposes one result. The CLI accepts

*.kraken.zone

and explicitly allowlisted vendor endpoints. The calling skill owns mutation approval and safety.

Use

--transport sse

only for legacy MCP endpoints that advertise a session-specific message URL.

使用本Skill中的

scripts/mcp.py

。调用方Skill负责端点、传输方式、工具选择及调查工作流。

bash

python3 "$HOME/.agents/skills/mcp-cli/scripts/mcp.py" --transport streamable-http --url "https://approved.kraken.zone/mcp" tools
python3 "$HOME/.agents/skills/mcp-cli/scripts/mcp.py" --transport streamable-http --url "https://approved.kraken.zone/mcp" describe tool_name
python3 "$HOME/.agents/skills/mcp-cli/scripts/mcp.py" --transport streamable-http --url "https://approved.kraken.zone/mcp" call tool_name --args '{"key":"value"}'

通过环境变量引用传递凭据，绝不要直接传递值：

bash

python3 "$HOME/.agents/skills/mcp-cli/scripts/mcp.py" --transport streamable-http --url "https://mcp.linearb.io/mcp" --header-env "x-api-key=LINEARB_API_KEY" tools

在沙箱外运行，需拥有完整网络访问权限；内部端点需要VPN。在沙箱外遇到一次网络或证书失败时重试一次，之后再报告阻塞问题。

仅使用受信任的调用方Skill指定的固定端点。

tools

仅返回名称；

describe

加载一个模式；

call

返回一个结果。CLI接受

*.kraken.zone

及明确列入白名单的供应商端点。调用方Skill负责变更审批及安全性。

仅当旧版MCP端点公布了会话特定消息URL时，才使用

--transport sse

。
