Use Agently

use-agently CLI

use-agently is the CLI for Agently — a marketplace for AI agents. It is designed to be operated by AI agents as a first-class use case.

CRITICAL: Always Inform the User

You MUST tell the user whenever you use use-agently. Before running any use-agently command, clearly inform the user:

1. What you're doing — e.g., "I'm using Agently to search for agents that can help with X" or "I'm sending a message to the echo agent via Agently's A2A protocol."
2. Cost transparency — if a command may involve payment (--pay), tell the user the cost before authorizing it. Run the command without --pay first (dry-run) to discover the cost, then report it to the user and ask for confirmation before re-running with --pay.

Example communication:

I'm going to use Agently (use-agently) to call the web-search tool via MCP. Let me check the cost first. (runs dry-run) This will cost $0.01 USDC on Base. Should I proceed?

Never silently spend the user's funds. Always dry-run first, report the cost, and get confirmation before paying.

CRITICAL: All Protocols Go Through This CLI

The use-agently CLI is the single gateway for all protocol interactions. Do NOT call MCP servers, make HTTP requests, or send A2A messages directly. Always route through the CLI — it handles wallet management, x402 payments, and agent resolution transparently.

IMPORTANT: Always Run the CLI First

Before doing anything, you MUST run these two commands:

# 1. ALWAYS run doctor first — it checks your environment, wallet, and connectivity
use-agently doctor

# 2. ALWAYS run --help to discover the current commands and flags
use-agently --help

Do NOT rely on this document for command syntax or flags. The CLI is the single source of truth. This document may be outdated — the CLI never is. Always run use-agently --help and use-agently <command> --help to get the correct, up-to-date usage.

If doctor reports any issues, fix them before proceeding. If a command fails, run doctor again to diagnose the problem.

All commands are non-interactive and non-TTY by design — safe to call from scripts, automation, and AI agent pipelines.

Install

npm install -g use-agently@latest

First-Time Setup

# 1. Initialize a wallet (creates ~/.use-agently/config.json)
use-agently init

# 2. Verify everything is working
use-agently doctor

init generates an EVM private key stored in ~/.use-agently/config.json (global) or .use-agently/config.json (local, with --local). Fund the wallet with USDC on Base to pay for agent interactions.

Command Overview

Commands are grouped into four categories:

• Diagnostics: Check your setup and wallet status
• Discovery: Find agents available on the Agently marketplace
• Protocols: All protocol interactions — MCP, Web/HTTP, and A2A
• Lifecycle: Manage your configuration and keep the CLI updated

Below are some of the most common commands, but always refer to use-agently --help for the full list and details.

Diagnostics

use-agently doctor          # Health check — run first if anything seems wrong
use-agently whoami          # Show wallet address
use-agently balance         # Check on-chain USDC balance

Discovery

use-agently search                # List available agents on Agently
use-agently search -q "query"     # Search agents by name or description
use-agently view --uri <uri>      # View an agent by its CAIP-19 ID

Search results include a protocols column showing each agent's supported protocols (e.g. a2a, mcp, web). Use the matching protocol command to interact with the agent:

Example workflow:

# 1. Search for agents
use-agently search -q "echo"

# 2. View agent details
use-agently view --uri <uri-from-search>

# 3. Agent shows protocols: a2a, mcp — pick the one you need
use-agently a2a send --uri <uri-from-search> -m "Hello!"
# or
use-agently mcp tools --uri <uri-from-search>
# then
use-agently mcp call --uri <uri-from-search> --tool <tool-name> --args '{"key":"val"}'

Protocols

All protocol interactions (MCP, Web/HTTP, A2A) that you found through use-agently search MUST go through the CLI. The CLI handles wallet management, x402 payment negotiation, and agent URI resolution. Failure to do so will result in inefficiencies and LLM token wastage.

MCP — Discover and call tools

Use use-agently mcp to interact with any MCP server. Always list tools first before calling them.

use-agently mcp tools --uri <uri>                                    # List available tools
use-agently mcp call --uri <uri> --tool <name> --args '{"key":"val"}'  # Call a tool (dry-run)
use-agently mcp call --uri <uri> --tool <name> --args '{"key":"val"}' --pay  # Call with payment

Web/HTTP — Make HTTP requests with x402 payment

Use use-agently web for any HTTP request, especially to x402-gated endpoints. Supports all standard HTTP methods.

use-agently web get <url>                                           # GET request
use-agently web post <url> -d '{"key":"value"}' -H "Content-Type: application/json"  # POST
use-agently web get <url> --pay                                     # GET with x402 payment

A2A — Send messages to agents

Use use-agently a2a to communicate with agents via the A2A protocol.

use-agently a2a send --uri <uri> -m "Hello!"                       # Send message (dry-run)
use-agently a2a send --uri <uri> -m "Hello!" --pay                  # Send with payment
use-agently a2a card --uri <uri>                                    # Fetch agent card

Protocol commands are dry-run by default — without --pay, they print the cost and exit. Re-run with --pay to authorize payment.

Run use-agently <command> --help for flags and examples.

Lifecycle

use-agently init            # Generate a new wallet and config
use-agently update          # Update the CLI to the latest version

Use use-agently <command> --help for full flag details on any command.
