Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.

Permissions Found in Source Code

Found by scanning the linked source code. This listing connects to a hosted endpoint, so none of this runs on your machine: it describes what the server software does where it is hosted.

file_system

Applies to the server that hosts this plugin, not to your machine.

HTTP Network Access

Connects to external APIs or services over the internet.

How to Connect

Remote Plugin

No local installation needed. Your AI client connects to the remote endpoint directly.

Add this to your MCP configuration to connect:

{
  "mcpServers": {
    "io-github-321zz321-computefirst": {
      "url": "https://computefirst.net/mcp"

ComputeFirst agent skill

Instructions for Claude Code, Codex, Grok, and other autonomous agents to use ComputeFirst for deterministic computation: search → read the versioned contract → execute. Free, no API key or sign-up. Live-verified catalog: 456 tools (2026-10-16).

Install the Claude Code skill and MCP connection from this repository's marketplace:

/plugin marketplace add 321zz321/computefirst-skill
/plugin install computefirst@computefirst

Or add the MCP connection alone:

claude mcp add --transport http computefirst https://computefirst.net/mcp

Codex ~/.codex/config.toml:

[mcp_servers.computefirst]
url = "https://computefirst.net/mcp"

For Codex skill discovery, copy skills/computefirst/ into .agents/skills/computefirst/ or ~/.agents/skills/computefirst/, preserving references. Client setup and sources cover Claude Code, Cursor, VS Code, generic MCP clients, and plain HTTP.

Read the skill for selection rules, exact requests, limits, and six actual API results. AGENTS.md provides condensed guidance. The full MCP route exposes gateway tools; /mcp/chatgpt offers 40 named operations with smaller limits.

Verify with Node.js 22+ and network access:

node scripts/verify-examples.mjs

The script reads the documented requests/results directly and fails on drift. It also checks discovery and both MCP routes. No dependencies, credentials, or reporting calls. MIT license.
