Common questions
Is Agentsim MCP safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.33.3) reached the registry 38 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

agentsim-mcp
Availability: Live SMS is self-serve for owned public HTTPS services after exact-origin verification and an allow policy. Hobby includes 10 live US SMS sessions per UTC month, with one active live session per account and no card required. Builder is $99/month and includes 50 live US SMS sessions. Checkout shows tax and renewal terms before payment, and existing agreements keep their terms. Check current access and channel support before using live examples.
MCP server that exposes AgentSIM challenge tools to AI coding assistants: Codex CLI, Claude Code, Cursor, Windsurf, and any other MCP-compatible host. Primary tools: open_challenge, wait_for_verdict. Aliases: provision_number, wait_for_otp.
Setup
For Codex CLI, follow Connect Codex. It covers key handling, the SMS wait timeout, and browser access. Then use the complete phone sign-in prompt.
Claude Code
claude mcp add agentsim -e AGENTSIM_API_KEY=asm_live_xxx -- uvx agentsim-mcpClaude Desktop
Add to ~/Library/Application Support/Claude/claude_desktop_config.json:
{"mcpServers": { "agentsim": { "command": "uvx", "args": ["agentsim-mcp"], "env": { "AGENTSIM_API_KEY": "asm_live_xxx" } } } }
Cursor / Windsurf
Add agentsim-mcp as a stdio MCP server with AGENTSIM_API_KEY in the environment config.
Remote (no install)
Connect directly to the hosted MCP server without installing anything locally:
{"mcpServers": { "agentsim": { "type": "streamable-http", "url": "https://mcp.agentsim.dev/mcp", "headers": { "x-api-key": "asm_live_..." } } } }
The hosted endpoint uses stateless HTTP and does not issue mcp-session-id headers. The session_id returned by AgentSIM tools identifies a challenge and remains valid across tool calls.
Tools
Control-Plane Nouns (Recommended)
| Tool | Description | |||
|---|---|---|---|---|
identify_agent | Add a stable agent ID to the console without opening a challenge, sending SMS, or using allowance | |||
open_challenge | Open an authentication challenge session for a required owned service_url; accepts channel (sms_otp \ | email_otp \ | magic_link \ | webauthn_required), returns session ID + identifier |
wait_for_verdict | Long-poll for the challenge verdict — returns structured outcome including otp_code, magic_link, or webauthn_required; policy denial fails on open | |||
get_messages | Read SMS metadata and parsed codes; reading codes consumes them | |||
release_number | Release a session early (allocation returned to pool) | |||
list_numbers | List all active sessions for this account |
Legacy Aliases (Backward Compatibility)
| Tool | Maps to | Description |
|---|---|---|
provision_number | open_challenge(channel=sms_otp) | Provision a temporary programmable US number for SMS OTP — kept for backward compatibility |
wait_for_otp | wait_for_verdict | Legacy wait with automatic extension after timeout by default; number may be unchanged |
Auth
For stdio, set AGENTSIM_API_KEY in the process environment. For hosted HTTP, every request must send its own x-api-key; the server validates and forwards that caller-scoped key. Get a key at console.agentsim.dev.
