ACI.dev is an open-source platform that lets AI agents call tools and services through direct functions or a shared MCP server. It is used to connect agents and agentic coding environments with services such as Google Calendar and Slack, while the catalogue entry provides an instruction for working with it.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01270 | $0.01270 |
| Opus 5 | $0.00635 | $0.00635 |
| Sonnet 5 | $0.00254 | $0.00254 |
| Haiku 4.5 | $0.00127 | $0.00127 |
Grade A, and why
aci CLAUDE.md 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.

Project Overview
ACI.dev is an open-source tool-calling platform providing 600+ integrations for AI agents. It serves as infrastructure for Unified MCP (Model Context Protocol) servers and VibeOps automated DevOps workflows. The platform handles multi-tenant authentication, granular permissions, and dynamic tool discovery.
Repository Structure
This is a monorepo with two main components:
backend/- FastAPI server with 600+ integrations (Python 3.12+, PostgreSQL, uv package manager)frontend/- Next.js 15 developer portal (React 19, TypeScript, Tailwind CSS, shadcn/ui)
Essential Development Commands
Backend Commands
cd backend
uv sync # Install dependencies
source .venv/bin/activate # Activate virtual environment
docker compose up --build # Start all services (includes PostgreSQL with pgvector)
docker compose exec runner ./scripts/seed_db.sh # Seed database
# Database management
docker compose exec runner alembic upgrade head # Apply migrations
docker compose exec runner alembic revision --autogenerate -m "description" # Create migration
# Testing and quality
docker compose exec test-runner pytest # Run tests
ruff format . # Format code
ruff check . # Lint code
mypy . # Type checking
# Admin CLI
docker compose exec runner python -m aci.cli --help
docker compose exec runner python -m aci.cli upsert-app --app-file ./apps/gmail/app.json
Frontend Commands
cd frontend
npm install --legacy-peer-deps # Install dependencies (React 19 compatibility required)
cp .env.example .env # Setup environment
npm run dev # Start development server
# Code quality
npm run format # Prettier formatting
npm run lint # ESLint
npm run test # Vitest in watch mode
npm run build # Production build
What this file has done since we first saw it
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.

aci CLAUDE.md is an instructions file published in the GitHub repository aipotheosis-labs/aci (4,889 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 1,270 tokens to every session, about $0.0064 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 2026-08-30.
