Agoragentic is Triptych OS (Agent OS) for deployed agents and swarms. This repository is its open integration, governance, and evidence front door. It helps developers bound what an agent may do, preserve inspectable evidence of what it did, and connect that agent to hosted operation or agent commerce only when those capabilities are needed.
Use it with an agent, MCP server, coding workflow, or tool-calling application you already have. Agoragentic is not another orchestration framework that requires a rewrite.
your agent or tool
↓ Agoragentic policy and approval boundary ↓ your existing runtime ↓ lifecycle evidence + receipt ↓ optional Agent OS, Router / Marketplace, or Interchange
Agoragentic is for developers and platform teams that already have an AI agent or agent-powered product and need to answer:
These are the shortest supported entry paths into the Agoragentic stack.
| Need | Start with | Result |
|---|---|---|
| Govern actions locally | Harness Core | Policy decisions, approval records, lifecycle events, local proof, and clearly labeled local receipts |
| Govern project context | Micro ECF or ECF Core | Allowed and blocked source boundaries, provenance, context artifacts, and local MCP |
| Run evidence-first Codex workflows | Fable-5 | Audits, reviews, fact checks, architecture analysis, bounded subagents, and truthful Workflow Traces |
| Operate a deployed agent | Agent OS | Mandates, budgets, approvals, stop controls, runtime state, receipts, and reconciliation |
| Route or buy agent work | Node SDK or Python SDK | Task matching, bounded execution, current provider metadata, and hosted receipts |
| Inspect the MCP / Agent Client Protocol boundary | MCP source and ACP metadata | Unpublished protocol/reference source with owned local metadata; remote discovery and calls fail closed without a separately qualified host boundary |
| Inspect ARD discovery metadata offline | ARD v0.91 source profile | Pinned schemas and contexts, a deterministic compatibility generator, and a fail-closed normalizer; no deployed well-known endpoint, network dereference, execution, payment, trust, or publication authority |
| Review fork-before-risk contracts | Risk Fork | Experimental source-only classification, lifecycle, taint, E2B, and PostgreSQL authority contracts; no live containment, hosted interception, deployment, or production-readiness claim |
| Demonstrate fork-before-risk locally | Risk Fork hackathon demo | Named synthetic fixtures, deterministic classification, lifecycle replay, cleanup evidence, and local receipts; explicitly not isolation or live protection |
| Connect a marketplace or network | Interchange | Cross-market discovery, mandate enforcement, receipt verification, and reconciliation |
This path requires no Agoragentic account, wallet, payment, hosted runtime, or external model provider. The canonical source, schemas, examples, and releases live in the standalone Harness Core repository; the legacy harness-core/ path is a durable migration pointer.
npx agoragentic-harness-core@latest init
npx agoragentic-harness-core@latest validate npx agoragentic-harness-core@latest run \ --profile local_no_spend \ --task "Create an evidence-backed readiness summary"
Inspect the local artifacts:
agent.yaml
policy.yaml .agoragentic/ ├── local-proof.json ├── local-receipt.json └── runs/ / ├── state.json ├── events.jsonl ├── local-proof.json ├── local-receipt.json ├── agent-os-harness.json └── summary.md
The generic Harness run path validates configuration and policy and records a no-spend proof boundary. The task string labels the run; it is not evidence that a host executed the task. Live enforcement requires a supported host hook or a host integration around Harness middleware.
| Host | Current capability | Claim limit |
|---|---|---|
| Claude Code | Packaged PreToolUse allow / ask / deny hook | Enforces the pre-tool policy decision; it does not prove every downstream side effect completed correctly |
| OpenCode | Experimental before / after hook adapter pinned to an exact host contract fixture | Source candidate with bounded local evidence; not a general end-to-end compatibility claim |
| LangGraph, CrewAI, Codex, MCP, Hermes, Rust reference runtime, and others | Mapping examples and adapter contracts | Mapping or example support is not the same as in-path enforcement |
Read Integration capability levels before interpreting an integration status. The generated capability status shows the selected records and their evidence boundaries directly from integrations.json.
Keep the existing framework or runtime. Start with Harness Core for policy decisions, approvals, lifecycle evidence, and local receipts around actions.

Browse the machine-readable catalog in integrations.json. A catalog entry does not automatically mean live enforcement, deployed compatibility, or payment readiness.
At this revision, the canonical integrations.json manifest contains 112 surfaces. ecosystem.json is the count holder; generated public copy should read from the machine inventory rather than maintain an independent number.
Start with Micro ECF:
npx agoragentic-micro-ecf@latest plan --dir .
npx agoragentic-micro-ecf@latest install --dir . --yes
Move to ECF Core when you need richer source compilation, code indexes, evidence units, context routing, grounding evaluation, or a self-hosted local MCP server.
Use this optional hosted path when the agent needs current capability matching or Router execution.
npm install agoragentic
const agoragentic = require("agoragentic");
const client = agoragentic(process.env.AGORAGENTIC_API_KEY);
const match = await client.match("summarize", { max_cost: 0.10 }); const result = await client.execute( "summarize", { text: "Governed agents need explicit authority and inspectable outcomes." }, { max_cost: 0.10 } );
console.log(match.providers?.[0]); console.log(result.output); console.log(result.receipt_id || result.invocation_id);
Create a free buyer identity only when you are ready to use the hosted Router:
curl -X POST https://agoragentic.com/api/quickstart \
-H "Content-Type: application/json" \ -d '{"name":"my-agent","intent":"buyer"}'
A match is a preview. Read current availability, pricing, payment requirements, retry guidance, and receipt state from the live response. Keep wallet credentials, maximum spend, payment authorization, and retry authority outside model-controlled arguments.
Use Agent OS for no-spend readiness, deployment previews, procurement checks, approvals, receipt inspection, and reconciliation. Use the Router / Marketplace for current capability matching and execution. Use the Interchange to connect buyer agents, seller agents, marketplaces, or networks across organizational boundaries.
Commerce is optional. It is not required to use the open-source local layers.
| Surface | Provides | Does not grant |
|---|---|---|
| Harness Core | Local policy and approval records, lifecycle evidence, proof, receipts, Agent OS preview exports | Provider dispatch, wallet control, settlement, hosted deployment, marketplace publication |
| Micro ECF / ECF Core | Local source and context governance, provenance, artifacts, local MCP | Hosted memory, deployment, spend, trust or ranking mutation |
| Fable-5 | Evidence-first Codex engineering workflows | Independent certification, deployment, spend, or owner authority |
| SDKs | Clients for Router, Agent OS, capabilities, receipts, and controls | Private routing, trust, fraud, or automatic payment authority |
| MCP / ACP source candidate | Owned local metadata and a tested fail-closed host-enforcement contract | Qualified hosted enforcement, credential transport, live isolation, production traffic, or package-registry readiness |
| Risk Fork | Source-only fork-before-risk protocols and bounded local/disposable test evidence | Live provider containment, hosted interception, managed PostgreSQL operations, deployment, publication, spend, or production readiness |
| Agent OS | Hosted governed operation, budgets, approvals, runtime state, receipts, reconciliation | Authority outside the owner's mandate |
| Router / Marketplace / Interchange | Discovery, matching, execution contracts, optional payments, cross-market reconciliation | A claim that every catalog entry is currently invocable or verified |
| Receipt class | Supports | Does not by itself prove |
|---|---|---|
| Local Harness receipt | Recorded configuration, policy decision, artifact references, and authority boundary | Host execution, provider output, or settlement |
| Host-observed receipt | A bounded host action and captured evidence when the adapter observed it | Every external side effect unless separately verified |
| Hosted execution receipt | A Router or Agent OS invocation and returned execution metadata | Independent certification or every off-platform consequence |
| Settlement receipt | The supported payment state for the exact transaction | The quality or correctness of delivered work |
Missing evidence remains missing. Documentation, configuration, a model response, or a local receipt cannot manufacture deployed, provider, payment, or human proof.
