@agnt-id/frameworks

Agent framework plugins for .agnt name resolution — LangChain, CrewAI, and ElizaOS.

Drop-in tools that let your agents resolve .agnt names, reverse-lookup addresses, and discover other agents — in whichever framework you use.

Install

npm i @agnt-id/frameworks @agnt-id/resolve

Or install everything at once:

npm i @agnt-id/sdk

LangChain

import {
  AgntResolveTool,
  AgntReverseTool,
  AgntDiscoverTool,
} from "@agnt-id/frameworks/langchain";

const tools = [
  new AgntResolveTool(),
  new AgntReverseTool(),
  new AgntDiscoverTool(),
];

// Use with any LangChain agent
const agent = createToolCallingAgent({ llm, tools, prompt });

Each tool follows the LangChain StructuredTool pattern with name, description, schema, and _call().

| Tool | Input | Description | |------|-------|-------------| | AgntResolveTool | { name: string } | Resolve a .agnt name | | AgntReverseTool | { address: string } | Address to name lookup | | AgntDiscoverTool | { query?: string, skill?: string, domain?: string } | Discover agents |

Custom Gateway

new AgntResolveTool({ gateway: "https://api.agnt.id", chainId: "eip155:8453" });

CrewAI

import {
  AgntResolveTool,
  AgntReverseTool,
  AgntDiscoverTool,
} from "@agnt-id/frameworks/crewai";

const tools = [
  new AgntResolveTool(),
  new AgntReverseTool(),
  new AgntDiscoverTool(),
];

// Use with CrewAI agents
const agent = new Agent({ role: "resolver", tools });

Each tool follows the CrewAI BaseTool pattern with name, description, and _run().

ElizaOS

import { agntPlugin } from "@agnt-id/frameworks/eliza";

const plugin = agntPlugin();

// Register with ElizaOS runtime
runtime.registerPlugin(plugin);

The plugin exposes 3 actions:

| Action | Description | |--------|-------------| | resolve_agnt | Resolve a .agnt name | | reverse_agnt | Address to name lookup | | discover_agnt | Discover agents by query |

Custom Options

agntPlugin({ gateway: "https://api.agnt.id", chainId: "eip155:8453" });

Sub-path Imports

Each framework has its own entry point to keep your bundle lean:

import { ... } from "@agnt-id/frameworks/langchain";
import { ... } from "@agnt-id/frameworks/crewai";
import { ... } from "@agnt-id/frameworks/eliza";

Or import everything from the root:

import {
  LangChainResolveTool,
  CrewAIResolveTool,
  agntPlugin,
} from "@agnt-id/frameworks";
