⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (SKILL.md not found in repo tree). The test below is what we measured on Jul 21, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.
Fetched SKILL.md and spot-checked 3 bundled files via raw GitHub (references/server-types.md, references/authentication.md, examples/stdio-server.json — all HTTP 200); example JSONs are real and valid, using ${CLAUDE_PLUGIN_ROOT}/${DATABASE_URL} correctly. For output I wrote two .mcp.json files for the same task (bundle a local Postgres stdio server + hosted Sentry SSE). Baseline (no skill) hardcoded an absolute path, embedded DB creds in the DSN (postgres://admin:pass123@...), hardcoded a Sentry token, and used http://; following the skill produced ${CLAUDE_PLUGIN_ROOT} paths, ${DATABASE_URL} env var, OAuth-based "type":"sse" with no token, and https:// — four concrete security/portability fixes. Noted but not penalized: I could not verify against live Claude Code whether plugin .mcp.json omits the top-level "mcpServers" wrapper (skill's examples do) or the exact mcp__plugin_... tool-naming format.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 5/5
- Output vs. baseline 7/10
- Docs & honesty 4/5
What Mcp Integration does
A documentation skill that guides configuring Model Context Protocol servers inside Claude Code plugins: choosing a transport (stdio, SSE, HTTP, WebSocket), writing .mcp.json or inline plugin.json entries, using ${CLAUDE_PLUGIN_ROOT} and env-var substitution, and pre-allowing MCP tools. Triggers when the user asks to add an MCP server, configure MCP in a plugin, use .mcp.json, or set up Model Context Protocol.
How to install Mcp Integration
Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
Commands — how to trigger Mcp Integration
-
/mcp-integrationReference for bundling MCP servers (stdio/SSE/HTTP/ws) into Claude Code plugins
It also activates on plain-language prompts like these:
-
Add an MCP server to this plugin -
Configure .mcp.json for an SSE connection -
Connect an external service via Model Context Protocol
Frequently asked questions
- Is the Mcp Integration skill free?
- Yes. The skill itself is free from tzachbon/smart-ralph. SkillProof publishes the install command and an independent test verdict at no cost.
- Does Mcp Integration work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 21, 2026. Verdict: Tested · Works.

- What is the Mcp Integration SkillProof Score?
- 8.4/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 7/10, docs & honesty 4/5.
- How do I install Mcp Integration?
- Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
- Can I use Mcp Integration with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
- The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
