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. Tagged 1.9.0 is the connector suite (pip install readyagentsdev). This checkout also has Unreleased A2A and memory — clone and pip install -e . to try those; they are not on the 1.9.0 tag.

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, foreach, a2a, and memory 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

  • Small governed connector set (rest, sql, object_storage, message, ingest) plus readyagents connectors catalog — connectors

  • Optional MCP client and server (readyagents mcp serve, readyagents mcp probe) with official tasks and MRTR approvals

  • Optional A2A serve/probe and type: a2a delegation (Unreleased on this checkout; 0.3 JSON-RPC projection; remote content untrusted; not certification)

  • Optional memory (type: memory, local JSON/SQLite, BM25, TTL/forget) — Unreleased on this checkout; untrusted; delayed injection and scope escape first; not a quality claim

  • 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

CLI

Command

Purpose

readyagents init

Execute (or --estimate without running). --stream is opt-in Unreleased

readyagents batch PATH --input-file FILE [--concurrency N] [--max-spend USD] [--out FILE]

Foreground: one workflow, many JSONL/CSV rows (opt-in; Unreleased)

readyagents attest RUN_ID

Data-residency attestation (technical evidence, not legal compliance)

readyagents bundle --out DIR

Offline wheel set for pip install --no-index --find-links

readyagents resume RUN_ID [--approve NODE] [--reject NODE] [--decision-file FILE] [--policy PATH]

Resume a paused or failed run

readyagents policy check PATH

Validate a firewall policy file (fail closed)

readyagents policy explain PATH [--policy PATH]

Show which tools each node may call and why

readyagents evidence RUN_ID [--out DIR]

Local evidence pack (not a compliance certificate)

readyagents audit verify [--file PATH]

Walk the hash-chained audit trail

readyagents spend [--since DATE] [--by day|workflow|model|actor|label]

TokenOps: aggregate the local spend ledger (informational vs the provider invoice)

readyagents graph PATH

Deterministic Mermaid routing (executes nothing)

readyagents decide RUN_ID [--file FILE | --node ID --decision approve] [--token-file JWT] [--actor NAME] [--reason TEXT]

Inject an approval; --actor stays the default, --token-file identifies

readyagents approvals list [--role ROLE] [--actor NAME] [--expiring-within 1h]

Queue of paused gates the caller may see

readyagents delegate --from A --to B --until TS [--scope ROLE]

Time-bounded, single-hop, revocable approval delegation

readyagents delegations list | revoke ID

List or revoke local delegations

readyagents identity verify --token-file JWT

Verify an assertion against local trust anchors

readyagents identity whoami

Workload fingerprint (never the private key)

readyagents runs list

List persisted runs

readyagents runs show RUN_ID

readyagents runs replay RUN_ID

New run from stored inputs

readyagents runs delete RUN_ID --yes

readyagents connectors list / show / test

readyagents sign / verify / lock / sbom / trust

Docs

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). The optional [sign] extra (Ed25519 artifact signatures) and [jwt] extra are also not in [all]. Unsigned default runs never import them.

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.
