LLM integration

Fountain is built to be consumed by AI coding tools. Every instance exposes machine-readable discovery endpoints so any agentic IDE can learn the full API from a single fetch.

Drop-in skill for Claude Code

mkdir -p ~/.claude/skills/fountain
curl -fsSL https://founta.inevitable.fyi/skill > ~/.claude/skills/fountain/SKILL.md

After that, telling Claude "spin up a researcher agent on Fountain and have it audit the auth module" Just Works.

Discovery endpoints

Endpoint	Content	Best for
/llms.txt	Concise API summary (~500 tokens)	Context-constrained models
/llms-full.txt	Full API reference	Deep tool-calling agents
/skill	Claude Code / Cursor skill file	IDE skills

curl https://founta.inevitable.fyi/llms.txt
curl https://founta.inevitable.fyi/llms-full.txt

Self-hosted instances

curl -fsSL https://your-fountain.example.com/skill > ~/.claude/skills/fountain/SKILL.md

MCP server (coming soon)

Fountain will ship a first-party MCP server exposing all four primitives as tools:

{
  "mcpServers": {
    "fountain": {
      "command": "npx",
      "args": ["-y", "@fountain/mcp-server"],
      "env": {
        "FOUNTAIN_TOKEN": "ft_your_api_key",
        "FOUNTAIN_ENDPOINT": "https://founta.inevitable.fyi"
      }
    }
  }
}

Using the API from an agent

1. Load the skill from /skill at session start
2. Authenticate with a Fountain API key stored in the agent's environment
3. Use the CLI or REST API to spin up sub-agents

Example prompt:

Please:
1. Create a Fountain conversation using the "security-auditor" agent
2. Set the prompt to: "Audit apps/fountain/lib/fountain_web/controllers/ for OWASP Top 10 issues"
3. Stream the output and report findings
