ReadyAgents Core

ReadyAgents is a free, self-hosted Apache-2.0 local one-shot agent workflow engine plus MCP toolkit: clone it, bring your own keys; always-on packs are waitlisted and not for sale. 1.0 means every run can be recorded, replayed offline, forked, diffed, and frozen into a regression test — with a written stability contract.

Site: readyagents.dev. Repo: github.com/readyagentsdev/readyagents-core.

Tried it? Open an I-ran-this issue. We are not launching. We are listening.

This repository is the free core. You keep the provider account and the bill. Install with pip install readyagentsdev, or from this clone.

60-second start

Requires Python 3.11–3.14 on Linux, macOS, or Windows. Current version is 1.5.1. Install with pip install readyagentsdev, or from this clone.

git clone https://github.com/readyagentsdev/readyagents-core.git
cd readyagents-core
python -m venv .venv
source .venv/bin/activate   # Windows: .venv\Scripts\activate
pip install -e .
readyagents run examples/calc_pipeline.yaml
readyagents runs list
readyagents doctor

readyagents run examples/calc_pipeline.json is the same graph.

Or from PyPI (the wheel does not ship examples/):

pip install readyagentsdev
readyagents new my-flow

What it does

• Define agent workflows as YAML or JSON (nodes + edges)
• Run agent, tool, condition, transform, approval, parallel, include, and foreach nodes. Agent nodes may declare a tools: allowlist for a bounded tool-use loop.
• Persist after every node and resume a paused or failed run from the last successful node
• Inspect past runs: readyagents runs list / show / replay / report (local HTML)
• Record, replay offline, fork, diff, and freeze a run into an eval fixture (time machine)
• Optional agent firewall: taint, tool policy, MCP pinning (security model, policy) — defence in depth, not a solution to prompt injection
• Scaffold a starter: readyagents new my-flow (basic, approval, research, pipeline, review, foreach, agent-tools, gated)
• Builtin tools with zero extra servers: now, calc, json_get, list_dir, read_file, write_file, optional http_get
• Optional MCP client and server (readyagents mcp serve, readyagents mcp probe) with official tasks and MRTR approvals
• Extra node types and tools via Python entry points (readyagents.packs)
• Per-node token/cost, budgets, --estimate / --max-spend caps, local spend ledger, model fallback, JSON logs
• External approval injection (readyagents decide) and outbound pause notify
• Secrets / RBAC / PII-redaction hooks and an append-only, hash-chained audit trail; readyagents evidence writes a local pack of a run — evidence, not legal compliance or certification (compliance)
• Pydantic output_schema on agent nodes; opt-in local LLM cache
• readyagents.testing helpers, recorded LLM mocks, and a tiny eval harness

Install extras

LLM and MCP extras are optional.

pip install "readyagentsdev[openai]"
pip install "readyagentsdev[anthropic]"
pip install "readyagentsdev[mcp]"
pip install "readyagentsdev[all]"

From a clone, the same extras are pip install -e ".[openai]" (and anthropic / mcp / all). The optional [otel] extra is not included in [all]; it starts no collector (see observability.md).

Then cp .env.example .env and paste your own keys. Core workflows that only use builtin tools do not need extras, keys, or Node.js.

docker compose run --rm readyagents run examples/calc_pipeline.yaml
make smoke

What is not in this repository

Always-on packs are waitlisted and not for sale.

Always-on / continuous workers are not in Core. The optional readyagents-pack-continuous distribution (separate repository, not a Core extra) can run configured workflows from an explicit foreground command. Installing Core still starts no scheduler or listener.

Hosted control plane. Hosted recovery and remote run stores. SSO, multi-tenant teams, billing.

The core has persist, resume, and approval pauses for a local one-shot. It does not run always-on.
