ContextNest ships connector packages for eight agent frameworks. Every package is an outbound, retrieval-only client that reads approved context from a hosted Community Nest over its public REST API — it just exposes that retrieval through whatever idiom the target framework uses (a knowledge source, a tool, a toolset, a retriever, a workflow node). This page lists each package, its status, and how it pulls context. For the shared connector design and licensing, see [Connectors](https://nest.promptowl.ai/d/promptowl-documents/platform/connectors/connectors).

## Framework support matrix

| Framework | Status | How it pulls context |
| --- | --- | --- |
| LlamaIndex | ✅ Supported | Retriever reading from the nest REST API |
| LangChain | ✅ Supported | Retriever reading from the nest REST API |
| CrewAI | ✅ Supported | Knowledge source |
| Google ADK | ✅ Supported | Toolset |
| Vercel AI SDK | ✅ Supported | Tool |
| OpenAI Agents SDK | ✅ Supported | Tool |
| n8n | ✅ Supported | Community node |
| Dify | 🔶 Partial | Tool plugin (needs live `.difypkg` validation) |

All eight read from the nest's public REST API. None bundles the ContextNest engine, and none writes back to the nest — retrieval only.

## Status legend

- ✅ **Supported** — connector is available and functional.
- 🔶 **Partial** — connector exists but has an outstanding validation gap. For Dify, the tool plugin still needs live `.difypkg` validation before it can be marked fully supported.

## Installation

Install names and pinned versions are not yet confirmed for this draft. Each connector is distributed for its framework's native package ecosystem (for example, a Python package for LlamaIndex, LangChain, CrewAI, Google ADK, and OpenAI Agents SDK; a JavaScript/TypeScript package for the Vercel AI SDK; a community node for n8n; and a plugin package for Dify). Confirm the exact identifiers against the Connectors repository before publishing.

## Prerequisites

Each connector reads from a published, readable nest. Before wiring up a framework, publish and expose the nest — see [Publishing a Nest](https://nest.promptowl.ai/d/promptowl-documents/platform/publishing/publishing-a-nest). Only approved snapshots are returned, per [Governance & Stewardship](https://nest.promptowl.ai/d/promptowl-documents/platform/governance/governance-stewardship).
