## Description

Access MCP (Model Context Protocol) servers and their tools, resources, and prompts through the mcpdo CLI, connections it holds extend your capabilities alongside any built-in MCP support. Use this skill for any question or task about MCP servers, connections, or tools (e.g. "what MCP servers am I connected to?", "what MCP tools do I have?"), and whenever a task requires inspecting, testing, or scripting against an MCP server (stdio or HTTP) rather than writing custom client code.

# mcpdo, MCP Inspector connection CLI

Connect to an MCP server once, then run many commands against that named
connection.

```bash
mcpdo servers/list                           # catalog entries you can connect
mcpdo connect entry-name                     # connect a catalog entry
mcpdo connect https://example.com/mcp        # ad-hoc HTTP/SSE target
mcpdo connect node server.js                 # ad-hoc stdio target

mcpdo connections/list                       # open connections
mcpdo @entry-name tools/list
mcpdo @entry-name tools/call <toolName> arg:=value
mcpdo @entry-name resources/list
mcpdo @entry-name resources/read <uri>
mcpdo @entry-name prompts/list

mcpdo --connection entry-name tools/list     # flag form of @entry-name

mcpdo disconnect entry-name
```

The canonical flow is `servers/list` → `connect <entry>` → `@entry <command>`.
Run `mcpdo help` or `mcpdo <command> --help` for the full, authoritative list of
commands and flags (auth management, elicitation controls, daemon control, and
more).
