create-mcp-integration

create-mcp-integration is a skill for Claude Code from richfrem/agent-plugins-skills. It costs 46 tokens per session (336 once invoked), scanned A, original, MIT.

A scaffold for adding an MCP server integration to an existing plugin. MCP is a standard way for an agent to connect to an external service and use selected tools from it.

In plain words
What is it for?
Use it to connect a plugin to services such as databases, GitHub, or Slack through a configured MCP server.
Why use it?
It collects the connection, authentication, transport, and tool details needed for the integration. It then generates configuration and explains how to verify the connection.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

create-mcp-integration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Follow the create-mcp-integration skill workflow to scaffold a new MCP server integration for a Claude Code plugin.

Inputs

  • $ARGUMENTS — optional MCP server name or service description (e.g. postgres, github, slack). Omit to start with discovery.

Steps

  1. If $ARGUMENTS names a server or service, use it to seed Phase 1 discovery
  2. Follow the create-mcp-integration phased workflow: confirm server type (stdio / SSE / streamable-http), authentication method, which tools to expose, configuration fields, then generate the .mcp.json entry and any supporting config
  3. Report the generated configuration and setup instructions

Output

.mcp.json server entry with full configuration (command/url, env vars, allowed tools) and instructions for obtaining credentials and verifying the connection with /mcp.

Edge Cases

  • If $ARGUMENTS is empty: begin with server type selection
  • If the service requires OAuth: document the auth flow steps explicitly
  • Prefer streamable-http transport for new hosted integrations over SSE
  • All MCP server URLs must use HTTPS/WSS — never HTTP/WS
Files

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
