readyagents/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.

Site: readyagents.dev. Repo: github.com/readyagents/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 readyagents, or from this clone.

60-second start

Requires Python 3.11+. Current version is 0.8.2. Install with pip install readyagents, or from this clone.

First-run clip: watch the 60-second run

git clone https://github.com/readyagents/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 run examples/calc_pipeline.json is the same graph.

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

pip install readyagents
readyagents new my-flow

HITL next: docs/first-ten-minutes.md.

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)
• 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)
• Extra node types and tools via Python entry points (readyagents.packs)
• Per-node token/cost, budgets, model fallback, JSON logs
• External approval injection (readyagents decide) and outbound pause notify
• Secrets / RBAC / PII-redaction hooks and an append-only audit trail
• Pydantic output_schema on agent nodes; opt-in local LLM cache
• readyagents.testing helpers, recorded LLM mocks, and a tiny eval harness

CLI

Command	Purpose
readyagents init	Write .env from .env.example if missing
readyagents new [name] [--template basic|approval|research|pipeline|review|foreach|agent-tools|gated]	Scaffold workflow + README + .env.example
readyagents validate PATH	Schema-validate a workflow
readyagents eval PATH	Score a keyless fixture suite (exit 0/1)
readyagents run PATH [--input KEY=VALUE] [--dry-run] [--approve NODE] [--reject NODE] [--decision-file FILE] [--actor NAME] [--pack PATH]	Execute
readyagents resume RUN_ID [--approve NODE] [--reject NODE] [--decision-file FILE]	Resume a paused or failed run
readyagents decide RUN_ID [--file FILE | --node ID --decision approve]	Inject an external approval decision and resume
readyagents runs list	List persisted runs
readyagents runs show RUN_ID	Node timeline + stored state (inspect is an alias)
readyagents runs report RUN_ID	Local HTML summary of a run
readyagents runs replay RUN_ID	New run from stored inputs
readyagents runs delete RUN_ID --yes	Delete one local run record
readyagents runs gc --yes	Prune succeeded/failed/cancelled runs (paused kept)
readyagents mcp serve	Stdio MCP server (builtin tools)
readyagents packs [--pack PATH]	List installed / local packs
readyagents version	Print version

Examples (no keys unless noted)

File	What it shows
examples/calc_pipeline.yaml	Builtin tools, transform, condition

examples/support_triage.yaml	Classify then branch (needs a key)
examples/code_review.yaml	read_file + review (needs a key)
examples/agent_tools.yaml	Agent tools: [calc] (needs a key; --dry-run is keyless)
examples/foreach_calc.yaml	Sequential foreach + calc (no keys)
examples/json_mutate.yaml	json_set / json_merge (no keys)
examples/list_dir.yaml	Builtin list_dir (no keys, no MCP, no Node)

Install extras

LLM and MCP extras are optional.

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

From a clone, the same extras are pip install -e ".[openai]" (and anthropic / mcp / all).

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 and schedulers. 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.
