MCP Integration Assistant

MCP Integration Assistant is a skill for Claude Code, Codex from Notysoty/openagentskills. It costs 23 tokens per session (2,428 once invoked), scanned A, original, MIT.

A guide for connecting an AI agent to an outside system, such as a database, API, file system, or other data source, through the Model Context Protocol (MCP). MCP is a standard way for agents to use external tools and information.

In plain words
What is it for?
Use it to design and implement an MCP server integration. It helps expose outside systems as tools, data resources, or reusable prompts for compatible AI agents.
Why use it?
It removes the need to work out the connection design, tool definitions, server code, client settings, and testing process from scratch.

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

MCP Integration Assistant 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 9d 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.

MCP Integration Assistant

What this skill does

This skill guides the design and implementation of a Model Context Protocol (MCP) server that exposes an external system, API, or data source as tools, resources, or prompts for AI agents. It designs the tool schema, writes the server handler code, generates the client configuration snippet, and explains how to test the integration. The output is a working MCP server ready for use with Claude Desktop, Claude Code, Cline, or any MCP-compatible agent.

Use this when you want to give an AI agent access to a new system — a database, an internal API, a third-party service, a file system, or any data source — through the standard MCP protocol.

How to use

Claude Code / Cline

Copy this file to .agents/skills/mcp-integration-assistant/SKILL.md in your project root.

Then describe what you want to expose and ask:

  • "Use the MCP Integration Assistant skill to build an MCP server for our Postgres database."
  • "Design an MCP integration for the GitHub API using the MCP Integration Assistant skill."

Describe the external system, what operations the agent should be able to perform, and any auth requirements.

Cursor

Add the "Prompt / Instructions" section to your .cursorrules file. Describe the system you want to expose and ask Cursor to design the MCP server.

Codex

Describe the target system and the operations you want to expose, then include the instructions below. Provide any relevant API docs or existing SDK code.

The Prompt / Instructions for the Agent

When asked to design an MCP integration, follow these steps:

  1. Understand the target system. Ask for or infer:
    • What external system, API, or data source needs to be exposed
    • What operations should the agent be able to perform (read, write, search, execute, etc.)
    • Authentication method (API key, OAuth, none, environment variable)
    • Any existing SDK or client library available
    • Programming language preference (TypeScript/Node.js is the primary MCP SDK language)

MCP Integration Assistant is a skill published in the GitHub repository Notysoty/openagentskills (9 stars, last pushed 26d ago), licensed MIT. It adds 23 tokens to every session and 2,428 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
