Paper forex trading for Agent Zero through the ReadyTrader-FOREX MCP server.
Installing the plugin installs the ReadyTrader-FOREX server into the plugin's own folder, registers it with Agent Zero's MCP client, and adds a paper-trading skill. Your agent can then read FX rates, candles, the economic calendar, a market brief and news, run backtests and risk checks, and place paper orders against a simulated FX account (USD cash, 30:1 leverage). The server always runs the paper profile — paper mode, trading halted, live execution disabled, every broker client that has a paper/sandbox/practice switch set to it, no broker keys — and the plugin has no switch that changes that.
Requires Agent Zero v2.13 or later (plugin system with lifecycle hooks), Git in the Agent Zero environment, network access to GitHub and PyPI during installation, and a ReadyTrader-FOREX version from its public-release update (PR #5, September 2026, or later). Earlier releases cannot start the way Agent Zero launches MCP servers, and installation refuses them.
Open Plugins in Agent Zero and click Install (the Plugin Hub). Either tab works; each runs
the plugin's install() hook:
- Git: enter
https://github.com/up2itnow0822/a0-readytrader-forex-plugin. - ZIP: download this repository as a ZIP and upload it.
Installation takes a few minutes. install():
- clones ReadyTrader-FOREX into
usr/plugins/readytrader_forex/server(branchmainby default) and installs its requirements intoserver/.venvwith Agent Zero's own Python (3.12+); - starts the server once over MCP stdio, checks that it offers the tools the skill uses, and checks
that it answers a brokerage-account call (
start_brokerage_private_ws) withpaper_mode_not_supported, i.e. that it runs in paper mode (this proves paper mode, not which server version it is); - adds an entry named
readytrader_forexunder Settings → MCP/A2A → External MCP Servers, pointing at that server with the paper profile. The name is fixed: the skill calls the tools asreadytrader_forex.<tool>. Your other servers are kept as they are (the settings JSON is saved back as{"mcpServers": {...}}, so comments and formatting in it are not kept), and nothing is written if any earlier step fails.
The server checkout gets an empty .env so ReadyTrader-FOREX does not read Agent Zero's own
usr/.env (your model API keys and UI password).
Copying the folder into usr/plugins/ by hand does not run install(); use the Git URL or ZIP
installer. (If you did copy it, open the plugin's settings and click Save: that runs the same
setup.)
Upgrading from 1.0.0: uninstall 1.0.0 first, then install this version. 1.0.0 has no install hook, so an in-place update would not set up the server.
Open a new chat and ask, for example, "What is EURUSD at, and what is on the economic calendar?" or
"Paper-buy 300 EURUSD after a risk check." The agent sees the server's 29 tools as
readytrader_forex.<tool> and the readytrader-forex-paper skill, which gives it the procedure: take
the rate from get_stock_price, read the account with get_paper_account, run validate_trade_risk
with the order's USD value and continue only when it allows the trade, then place a market order in
units without a price (the server fills it at its market rate and repeats the risk check against the
account). Each order may be at most 5% of equity; the limit applies to each order, not to the
position, so several orders can build a larger one. The paper account and order history are kept
in usr/plugins/readytrader_forex/data.
Paper orders fill at once: the entry sets ReadyTrader-FOREX' approval mode to auto, because in
approve_each mode the server holds even paper orders for an operator approval that no agent can
give. Approvals exist for live orders, and this plugin never enables live trading.
Asking for a live trade gets a refusal. Live trading is an operator process run on ReadyTrader-FOREX itself, with its own broker keys and approvals, never through this plugin.
The plugin's settings screen (Settings → External, or the plugin's entry under Plugins) holds
the server repository and version (branch, tag or full commit SHA) and the start-up and tool-call
timeouts. The paper profile and the MCP server name (readytrader_forex) are not settings.
Saving applies the settings at once: the server is moved to the chosen version, checked, and the
MCP entry is registered again. A version change can take a few minutes. If any step fails, the
settings are not saved, a notification names the step, and the server goes back to the version it
was on (a server folder the setup had to create is moved aside as server.failed-* instead of being
left behind the MCP entry). Saving again without changes re-runs the setup, which also repairs it (for
example after an Agent Zero upgrade changed its Python), and makes Agent Zero reload the server's tools.
The MCP settings must be strict JSON for any of this: the plugin will not rewrite settings with
comments or trailing commas, because that could drop what you wrote.
To choose a setting before the first install (for example a server version), give Agent Zero the environment variable
A0_SET_readytrader_forex__<setting>, e.g. A0_SET_readytrader_forex__server_ref=v1.2.3 (in
usr/.env, or -e for the Docker container), and restart Agent Zero. The install uses it while no
settings have been saved; once you save the settings screen, the saved values win. (The screen's
Reset to default shows the plugin's own defaults, not the preset.)
The server repository is code the plugin runs: the setup clones it, installs its requirements and
starts its app/main.py with Agent Zero's Python. Leave it at ReadyTrader-FOREX, or point it only at
a fork you trust.
- A newer plugin version: installed from the Plugin Index, use Update on the plugin's Plugin
Hub page; it re-runs
install()and keeps the paper wallet. Installed from a Git URL or ZIP (Agent Zero offers no Update button for those), uninstall and install again; that resets the settings and the paper wallet. - A newer server version: set it in the settings and save.
- Uninstall removes the
readytrader_forexMCP entry, then Agent Zero deletes the plugin folder, including the server and the paper wallet. If the MCP settings cannot be read, the uninstall still goes ahead and the log says which entry to remove by hand.
- Install or save fails: the message names the step (cloning, fetching the version, installing requirements, starting the server, the paper-mode check). Check that Agent Zero can reach GitHub and PyPI, then try again.
- A start-up error naming a missing module (
No module named 'app',pydantic_settings): the server version predates ReadyTrader-FOREX' public-release update, whose releases cannot start the way Agent Zero launches MCP servers. Set a newer server version. - "the server did not show that it runs in paper mode": the server answered the paper-mode check
with something other than
paper_mode_not_supported, so the plugin did not register it. Set a ReadyTrader-FOREX version with PR #5 or later. - "An MCP server named ... already exists (Agent Zero calls it readytrader_forex)": you have your
own entry with that name, or one Agent Zero treats as the same (it lowercases names and turns other
characters into
_). Remove or rename it, then install again (or save the plugin settings). The plugin cannot use another name: its skill calls the tools asreadytrader_forex.<tool>, and with another name those calls would reach your server instead. - No tools in the chat: open Settings → MCP/A2A → External MCP Servers and check the entry's status and tool count. An Agent Profile with a custom tool policy can block MCP tools. Saving the plugin settings re-runs the setup.
- Market data errors behind a proxy: Agent Zero starts MCP servers with a minimal environment
(no proxy variables). Add
HTTPS_PROXY(andNO_PROXY, or a CA bundle variable if your proxy needs one) to thereadytrader_forexentry'senvin the MCP settings. The setup keeps only these variables there (any letter case):HTTP_PROXY,HTTPS_PROXY,NO_PROXY,ALL_PROXY,SSL_CERT_FILE,SSL_CERT_DIR,REQUESTS_CA_BUNDLE,CURL_CA_BUNDLE,WEBSOCKET_CLIENT_CA_BUNDLE,TZ,LANG,LC_ALL. Anything else you add (broker or provider keys, other ReadyTrader settings) is removed the next time the setup runs, and the paper-profile and data-path variables are always reset. - Projects: a project whose own MCP settings define a server Agent Zero also calls
readytrader_forexuses that server instead of this one inside that project. - Slow first call: Agent Zero starts the server afresh for every call; allow a few seconds.
python -m pip install -r requirements-dev.txt
