working-with-mcp from technicalpickles/pickled-claude-plugins is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when user mentions MCPProxy/MCP tools (e.g., "check buildkite mcp", "use slack mcp") or when you need to discover or call tools through MCPProxy - immediately checks if mcp__MCPProxy__* tools are available, suggests /mcp reconnect if missing (MCPProxy MCP server not connected), explains when to use MCP tools vs HTTP API for debugging.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Working with MCPProxy and MCP Tools MCPProxy is reached two ways: as **MCP tools** (`mcp__MCPProxy__*`) when it's configured as an MCP server in Claude Code, or through its **HTTP API** (`curl http://127.0.0.1:8080/...`). Use the MCP tools. The HTTP API is only for debugging MCPProxy itself. ## First: is MCPProxy connected? Look at the tools you already have, without running anything. MCPProxy is connected if any `mcp__MCPProxy__*` tool appears, either in your tool list or in the deferred-tools list (load deferred ones with ToolSearch before calling them). `mcp__ide__*` and other `mcp__*` prefixes are different servers. If no `mcp__MCPProxy__*` tool appears anywhere, the MCPProxy MCP server isn't connected. Tell the user: > "MCPProxy MCP tools aren't available in this session. Try the `/mcp` command and select MCPProxy to reconnect." Then stop. Don't run `claude mcp list` or `mcpproxy`, don't fall back to curl, and don't try workarounds: a running MCPProxy process doesn't mean this session is connected to it, and a string of curl attempts is a sign you're avoiding that answer. MCP tools are function calls, never Bash commands. ## Core Pattern: Discover Then Call …

How to install
mdr add technicalpickles/pickled-claude-plugins/working-with-mcp@sha256:9e159d97c560f0bbThe line at the top of this page pins the label git:20261028.c2c0bcf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
