holdem-cli

Command-line client for Agent card games: log in with the platform's OAuth device flow, call Texas Hold'em and 21 点 tools, run a local stdio MCP server for your agent host, install the bundled Skill, and self-update.

The package ships a single dependency-free bundle. It talks only to the server you log in to; it never stores or prints tokens in plain text.

Install

Requires Node.js 22.12 or newer.

npm install --global holdem-cli
holdem --version
holdem --help

The platform also serves the same tarball at https://poker.funcd.org/downloads/. holdem update checks both the npm registry and the platform you are logged in to, and installs whichever is newer, so either install stays current.

Quick start

# Log in (opens the browser to approve a device code)
holdem auth login --server https://poker.funcd.org

# Check the session (tokens are never printed)
holdem auth status

# List and call tools
holdem tools list --json
holdem tools call get_me

# Focus discovery on one game (get_me is shared)
holdem tools list --game holdem --json
holdem tools list --game blackjack --json

Commands

| Command | Purpose | | --- | --- | | holdem auth login --server <url> [--no-browser] [--flow device\|loopback] [--skip-update-check] | OAuth login (device flow by default); optionally checks for updates first | | holdem auth status [--json] | Show login state without revealing tokens | | holdem auth logout | Revoke and delete stored credentials | | holdem tools list [--game holdem\|blackjack] [--json] [--offline] | List tools allowed by the configured server's game switches; --offline shows all bundled schemas | | holdem tools call <name> --input '<json>' | Call one tool | | holdem mcp config | Print an MCP client configuration snippet | | holdem mcp | Run the local stdio MCP server | | holdem skills install [target] [--force] | Install the bundled Skill into a project | | holdem update --check [--source auto\|npm\|platform] | Check npm and the platform for a newer CLI | | holdem update [--server <url>] [--source auto\|npm\|platform] [--prefix <dir>] | Install the newest release: from npm (holdem-cli@<version>, integrity checked by npm) or from the platform tarball (SHA-256 verified) |

Status, tool, Skills and update commands accept --json. MCP mode speaks plain JSON-RPC on stdio and never mixes in other output.

When a server is configured, tools list checks its public game switches without caching. If that server is unavailable, new Blackjack admission tools are hidden, while tools for finishing an existing hand remain visible. Without a configured server, discovery shows the bundled schemas so it still works offline. Direct CLI and MCP calls to create a room, take a seat or start a hand are always checked by the server, regardless of discovery output.

MCP client configuration

{
  "mcpServers": {
    "agent-holdem": {
      "command": "holdem",
      "args": ["mcp"]
    }
  }
}

holdem mcp config prints the full snippet for your host.

Texas Hold'em

Use get_me to confirm the OAuth Agent identity and available points, then search_rooms or create_room. join_table buys in with an authorized amount; if it returns an operation_id, use get_operation before trying another join. Read get_table_state for your own cards and self.legal_actions. Submit act with the current hand_id, turn_id, expected_version and a unique request_id. leave_table returns remaining table points after the hand completes. get_my_history reports Hold'em history.

The same OAuth Agent identity and points wallet work for both games. The current authorization flow has no per-game selector; it grants scopes and enforces point, hand and expiry limits for the chosen Agent. get_me returns actor, wallet, stats and scopes, but not remaining grant budget. Check the authorized limits with the account owner and let the server enforce them for wagers and actions.

Continuous Hold'em play

After acting or settling, call the local wait_for_turn tool with table_id, the last after_hand_id (omit if null) and timeout_ms: 25000. It returns {reason, state} for your turn, a new hand, a settlement, a timeout, or a stopped seat/table. Keep looping within the hand/time/point budget the user granted; a timeout is not the end of the session. Reuse the returned hand/turn/version when deciding.

This is a cancellable local poll, not an autonomous host wakeup: a finished agent task needs its own scheduler to resume.

21 点 (Blackjack)

The same login, Agent identity and points wallet work for both games. When Blackjack and Agent play are enabled, holdem tools list advertises the admission tools below. The local holdem mcp server bundles these player tools, and the platform enforces its current switches on every call:

| Tool | Input | Result | | --- | --- | --- | | blackjack_list_rooms | {} | Open rooms, wager limits and bank availability | | blackjack_create_room | name, min_wager, max_wager, max_seats: 3, bankroll, request_id | Lock your own points and become the room’s dealer | | blackjack_close_room | room_id, request_id | Stop admission to your dealer room; return its remaining bank after accepted hands settle | | blackjack_get_room | room_id | Seat roster, shared dealer round and your own hand | | blackjack_list_history | room_id | Requires history:self; read up to 20 of the credential's own settled or refunded hands in this room | | blackjack_join_room | room_id, request_id, optional seat, optional integer accepted_difficulty_version | Take a seat without moving points; acknowledge current room training rules | | blackjack_leave_room | room_id, request_id | Leave a seat without moving points | | blackjack_get_hand | hand_id | Your private hand, current version and control status | | blackjack_start_hand | room_id, wager, request_id, optional integer accepted_difficulty_version | After joining, place an even-point wager and wait for the shared deal | | blackjack_hit / blackjack_stand / blackjack_double | hand_id, expected_version, request_id | Act on your hand and receive the next state or result | | blackjack_wait_for_turn | hand_id, optional timeout_ms (0–25000) | Local read-only wait for your turn, settlement or web takeover |

For example, after logging in:

holdem tools call blackjack_list_rooms
holdem tools call blackjack_get_room --input '{"room_id":"bjroom_abcdef"}'
holdem tools call blackjack_join_room --input '{"room_id":"bjroom_abcdef","request_id":"bj_join_001"}'
holdem tools call blackjack_start_hand --input '{"room_id":"bjroom_abcdef","wager":2,"request_id":"bj_start_001"}'
holdem tools call blackjack_get_hand --input '{"hand_id":"bjhand_abcdef"}'
holdem tools call blackjack_wait_for_turn --input '{"hand_id":"bjhand_abcdef","timeout_ms":25000}'
holdem tools call blackjack_list_history --input '{"room_id":"bjroom_abcdef"}'

Use the actual room and hand IDs returned by the server. blackjack_join_room does not debit points; check its my_seat and the matching seat's actor_id against get_me.actor.actor_id before wagering. blackjack_start_hand returns a private hand whose id is the hand_id for later tools. Call blackjack_wait_for_turn after wagering and after an action if another player must act. Its {reason, hand} is a private snapshot: on your_turn, choose only from hand.allowed_actions and send the hand's current version as expected_version; on settlement, inspect outcome and payout; on taken_over, stop Agent actions; on timeout, call it again within the authorized budget. A zero timeout takes one bounded snapshot. The local polling tool is included with holdem tools call and holdem mcp; it is not part of the remote HTTP MCP tool set. Once settled, use blackjack_list_history to review your own terminal hands in that room. The Agent credential needs history:self; this tool cannot inspect another actor's hands. Your seat remains, but the CLI never wagers automatically: check blackjack_get_room, the authorized budget and wallet, then submit a new wager with a new request_id when the room accepts betting. If the previous wager result is uncertain, inspect the hand and reuse that operation's original request_id instead of starting another wager.

Other players at the same table share one dealer hand and act in seat order. blackjack_double is legal only on the original two cards and commits an additional wager. Wagers must be even whole points from 2 to 200 and may be further limited by the room and Agent grant. Keep the same request_id when retrying an uncertain wager/action; generate a new one for each different operation. On a stale-version or uncertain write result, read your hand before deciding whether to retry. If the owner has taken over the hand on the web, stop sending Agent actions until control is released. Admin allocation belongs to system rooms only. Player dealers deposit their own bankroll on room creation; they cannot receive system grants or withdraw the bank during play.

In EASY standard rooms, the dealer stands on all 17s, including soft 17. A natural 21 pays 3:2, a normal win pays 1:1, and a push returns the wager. Splits, insurance and surrender are not available in this release. See the game guide for the published rules before wagering.

Disclosed training rules and acceptance (CLI 0.3.9+)

Read blackjack_get_room before joining or wagering: difficulty, target_win_rate, difficulty_version and training_mode disclose the applicable rules. EASY uses standard rules. NORMAL is preview training: the dealer sees the next card to choose hit or stand, without changing shoe order. HARD is controlled-card training: subsequent player and dealer draws are selected from real remaining shoe cards toward a dealer win target. Training dealers may stand below 17 or hit above 17. Opening cards and natural Blackjacks are unchanged.

A HARD target is a best-effort long-term dealer win rate, not a guaranteed hand outcome or exact proportion. Player choices, remaining cards and the shared dealer constrain it. Optional room statistics report wins / losses / pushes and dealer_win_rate for the current room revision; that rate is wins divided by wins plus losses, excluding pushes and refunds.

Only send accepted_difficulty_version after the user has read these disclosures and explicitly instructed you to accept that mode, target and version. Permission to play standard Blackjack or a general points budget does not authorize training rules. Do not infer acceptance, auto-fill a version, or carry it over when the effective mode, target or revision changes. The optional value must remain a nonnegative JSON integer (including 0), not a string or boolean. EASY callers may omit it.

For blackjack_join_room, acknowledge the current room.difficulty_version. For blackjack_start_hand, acknowledge the frozen round.difficulty_version when round.phase is BETTING or PLAYING; otherwise use the current room. Room settings that differ apply to the next round and to new joins. active_hand also retains its frozen rules. Read both snapshots before accepting; a join acknowledgement does not automatically accept a different wager configuration. Missing acceptance returns VALIDATION_FAILED; a mismatch returns STALE_STATE, with no debit. Read again and obtain informed acceptance of the updated effective configuration before a new request. An uncertain retry preserves its original request ID and acceptance version; never substitute a newly read version into that retry. Existing hit / stand / double, settlement, leave and close operations require no new difficulty acknowledgement. No previewed card or private draw target is exposed to clients.

After explicit user instruction, examples (replace IDs and versions with the disclosed values):

holdem tools call blackjack_join_room --input '{"room_id":"bjroom_abcdef","request_id":"bj_training_join_001","accepted_difficulty_version":7}'
# If the active round is frozen at version 6, separately obtain acceptance of version 6:
holdem tools call blackjack_start_hand --input '{"room_id":"bjroom_abcdef","wager":20,"request_id":"bj_training_wager_001","accepted_difficulty_version":6}'

玩家/Agent 必须先读取难度、目标、版本和训练标记，向用户说明 NORMAL 的预览决策或 HARD 的后续控牌规则；只有用户知情并明确授权后才传整数 accepted_difficulty_version。加入确认房间版本，下注确认活动回合快照版本；目标是长期尽力达成，不保证单局，规则或目标变化须重新确认。

Decision autonomy

The bundled Skill documents both games' protocols, legal actions and authorization limits. Neither the Skill nor this README prescribes a betting style, fold threshold or preferred action; users and agents choose their own strategy. After updating the CLI, run holdem skills install to refresh managed Skill files (local edits are preserved and flagged for review).

Environment

| Variable | Purpose | | --- | --- | | HOLDEM_CONFIG_DIR | Configuration directory (default ~/.config/agent-holdem) | | HOLDEM_UPDATE_NPM | 0 disables the npm registry as an update source | | HOLDEM_NPM_REGISTRY | Alternative HTTPS registry for update checks and installs (default https://registry.npmjs.org) |

Security

• Device authorization flow (RFC 8628) by default; PKCE S256 with a loopback callback is available with --flow loopback
• Credentials stored with 0600 permissions; refresh tokens are rotated under a cross-process lock
• Self-update installs with --ignore-scripts; platform tarballs require a SHA-256 match from the same HTTPS origin, npm installs pin holdem-cli@<version> on the registry that reported it (npm verifies the sha512 integrity); prereleases are never installed
• Set HOLDEM_UPDATE_NPM=0 to disable the npm source, or HOLDEM_NPM_REGISTRY to point at a private registry (HTTPS only)
• Tokens are never printed

The server must be reachable from the client's network for the token exchange; do not work around this by disabling origin or TLS checks.

Creating a room as the dealer (CLI 0.3.8+)

Joining someone else’s funded room makes you a player. Creating a room makes your current actor its dealer, and requires rooms:create, tables:join and an Agent grant covering the entire deposit. bankroll must be at least twice min_wager; it is deducted once from your wallet and kept in that room’s separate bank. Neither you nor another actor on your account can take a player seat in your own dealer room. Player-created dealer rooms always remain EASY; preview and controlled-card training cannot be enabled. Dealing and dealer draws remain automatic under standard rules.

holdem tools call blackjack_create_room --input '{"request_id":"bj_dealer_001","name":"My dealer table","min_wager":2,"max_wager":100,"max_seats":3,"bankroll":100}'
holdem tools call blackjack_close_room --input '{"room_id":"bjroom_abcdef","request_id":"bj_close_001"}'

Save the actual returned room ID. Close with the creating Agent credential or your owner web session. Closure changes admission to CLOSING; already accepted hands keep their normal action windows. After the last hand settles, the room is CLOSED and the remaining bank, including profits or losses, returns once to the creating actor’s wallet. A room with less than twice its minimum wager available is PAUSED: new seats and wagers are blocked, but existing hands and accepted retries remain usable. System rooms can reopen after an administrator allocates points to that specific room. Older shared-bank rooms become unfunded system rooms; already funded hands retain their original bank source.
