agentforge-mcp

Stop re-explaining what you want to your AI coding agent.<br/> Hand it one rough sentence — get back a structured, tool-tuned prompt it can execute in one pass.

agentforge.sciscale.org · Quick start · npm

agentforge-mcp is the Model Context Protocol server for AgentForge. One tool, one job: turn a vague request into a sharp one.

Why

You know the loop: you ask your coding agent for something, it misreads the half you didn't spell out, you correct it, it breaks something else, you re-explain. The fix isn't a smarter agent — it's a sharper prompt.

AgentForge does the prompt engineering for you. Give it "add a dark mode toggle that persists" and it:

• extracts the real requirements — the edge cases, the acceptance criteria, the things you'd have forgotten to mention;
• formats for your specific agent — Claude Code wants file:line references, Cursor wants directives, Aider wants tight context;
• quality-checks before returning — every prompt is scored across 12 dimensions before it leaves the engine.

Harness engineering is having a moment — but prompt engineering matters more in the coding-agent era, not less. Tested across 1,000+ real coding cases, projects with AgentForge in the loop reached a deployable state 147% faster.

Quick start

No install — it runs through npx.

1. Get an API key. Sign in at agentforge.sciscale.org, open API keys, and create one. The key is shown once — copy it.

2. Add it to your agent.

Claude Code:

claude mcp add agentforge --env AGENTFORGE_API_KEY=af_your_key -- npx -y agentforge-mcp

Cursor / Windsurf / Claude Desktop — add to your MCP config (~/.cursor/mcp.json, ~/.codeium/windsurf/mcp_config.json, etc.):

{
  "mcpServers": {
    "agentforge": {
      "command": "npx",
      "args": ["-y", "agentforge-mcp"],
      "env": { "AGENTFORGE_API_KEY": "af_your_key" }
    }
  }
}

3. Use it. Ask your agent naturally — "refine this with AgentForge, then build it: add a dark mode toggle that persists."

The tool — agentforge_refine_prompt

Returns the refined prompt, plus its Quality Engine score and your remaining daily usage.

How it works

agentforge-mcp is a thin client — no engine logic ships in this package. Your request goes to the AgentForge API, the hosted engine does the extraction, formatting, and quality-checking, and the prompt comes back. The engine keeps improving without you ever updating this package.

Configuration

Develop

npm install
npm run build      # tsc -> dist/
node dist/index.js # runs on stdio
