Build what your agent can do.

Define tools, compose workflows, test and run them. MCP servers, REST APIs, and CLI commands in one config, one UI, one audit log.

Factorly is a local runtime for agent tool chains. It manages tool calls, injects credentials from an encrypted vault, enforces governance rules, and logs everything. Your agent sees workflows, tools, and data. Secrets stay secret.

Install

Install with your package manager of choice:

brew install factorly-dev/tap/factorly
  # or: npm install -g factorly
  # or: pip install factorly
  # or: go install github.com/factorly-dev/factorly@latest

Quick Start

Then, define your tools, secure your credentials, and sync with your agent:

# 1. Configure your tools or install a blueprint (41 services: GitHub, Slack, Stripe, Linear, Gmail, ...)
factorly init
factorly blueprint install github

# 2. Store your credentials in the encrypted vault
factorly vault set GITHUB_TOKEN ghp_xxxxxxxxxxxx

# 3. Connect to your agent (auto-detects Claude Code, Cursor, Codex)
factorly sync

# 3. Optional, start the UI
factorly ui

Your agent connects to Factorly as a single MCP server or CLI and sees every tool you've configured. Credentials never leave the vault.

What It Does

Define — one config, every protocol, 40+ blueprints included

Test — Try tools in the UI, see the response, iterate before giving your agent access

Compose — workflows with per-step policies, deterministic sequences

Govern — vault, policies, audit log. Built in, not bolted on.
