add-mcp

add-mcp is a command for Claude Code, Cursor from AlexFischman/mcp-skill-creator-agency. It costs 0 tokens per session (4,629 once invoked), scanned A, a copy of add-mcp, MIT.

A setup command for connecting an Agency Swarm agent to an MCP server. MCP, or Model Context Protocol, is a standard way for agents to use outside tools and data.

In plain words
What is it for?
Use it to connect an agent to remote web services, streaming HTTP or event servers, local scripts, command-line tools, or GitHub-hosted servers.
Why use it?
It removes the need to work out how different MCP server types and connection methods fit into the agent.

Command for Claude CodeCursor

Written for Cursor and Claude Code: installed under .cursor/, but also a Claude Code command (commands/*.md).

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is git clone <repository-url> ./mcp_servers/<server-name>.

Good fit Use it to connect an agent to remote web services, streaming HTTP or event servers, local scripts, command-line tools, or GitHub-hosted servers.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

add-mcp 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 11d 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.

Origin

This is a copy

89% identical to add-mcp — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

MCP Server Creation Task

Your task is to add Model Context Protocol (MCP) server to an Agency Swarm agent. MCP servers expose external tools and data sources to agents through a standardized protocol.


Quick Reference: MCP Server Types

Server Type When to Use URL Pattern Class to Use
Hosted Remote Publicly accessible web service Any public URL HostedMCPTool
Hosted Remote (OAuth) Publicly accessible web service with OAuth Any public URL MCPServerStdio + mcp-remote
Streamable HTTP HTTP streaming server Ends in /mcp MCPServerStreamableHttp
SSE Server-Sent Events server Ends in /sse MCPServerSse
Local/Stdio GitHub repo, local script, or CLI tool GitHub URL or local path MCPServerStdio

Step-by-Step Process

Step 1: Determine Server Type

If user provides a URL:

  • Check if it's a public/internet-accessible URL:
    • Requires OAuth authentication? → Use mcp-remote with MCPServerStdio
    • No authentication or token-based auth? → Use HostedMCPTool
  • Check if URL ends with /mcp → Use MCPServerStreamableHttp (or HostedMCPTool if public)
  • Check if URL ends with /sse → Use MCPServerSse (or HostedMCPTool if public)

If user provides a GitHub URL or mentions "local":

  • Use MCPServerStdio

If unclear, ask:

  1. Is this a publicly accessible URL? (HostedMCPTool or mcp-remote)
  2. Does it require OAuth authentication? (Use mcp-remote)
  3. Is this a local server you'll run? (MCPServerStdio, MCPServerSse, or MCPServerStreamableHttp)
  4. What's the server endpoint URL? (check /mcp or /sse suffix)
  5. Which agent do you want to add this MCP server to?

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.
