Quick Start

Claude Code (Terminal)

npx @aibtc/mcp-server@latest --install

This configures Claude Code and creates the agent's wallet: it prints the Stacks and Bitcoin addresses, a generated password and the 24-word mnemonic once. Write both down. The mnemonic is stored only encrypted (AES-256-GCM) in ~/.aibtc/ on this machine, and the password is not saved anywhere; the agent asks for it to unlock, and you can change it with wallet_rotate_password. If a wallet for the network already exists it is kept. The wallet is only created when the install runs in an interactive terminal (never into a pipe or CI log). Pass --no-wallet to skip it and create or import one from the agent instead.

Restart your terminal, send a little STX to the printed address, and ask the agent to unlock the wallet and make a paid inference call.

Claude Desktop (App)

npx @aibtc/mcp-server@latest --install --desktop

This detects your OS and writes to the correct Claude Desktop config file:

OS	Config Path
macOS	`~/Library/Application Support/Claude/claude_desktop_config.json`
Linux	`~/.config/Claude/claude_desktop_config.json`
Windows	`%APPDATA%/Claude/claude_desktop_config.json`

Restart Claude Desktop after installing.

Other MCP Clients

This is a standard stdio MCP server, so it works with any MCP-compatible client. Claude Code is the default --install target; select another client with a flag:

npx @aibtc/mcp-server@latest --install --cursor     # Cursor
npx @aibtc/mcp-server@latest --install --windsurf   # Windsurf
npx @aibtc/mcp-server@latest --install --gemini     # Gemini CLI
npx @aibtc/mcp-server@latest --install --codex      # OpenAI Codex CLI
npx @aibtc/mcp-server@latest --install --vscode     # VS Code (writes ./.vscode/mcp.json)

Flag	Client	Config written
(none)	Claude Code	`~/.claude.json`
`--desktop`	Claude Desktop	`claude_desktop_config.json` (see path table above)
`--cursor`	Cursor	`~/.cursor/mcp.json`
`--windsurf`	Windsurf	`~/.codeium/windsurf/mcp_config.json`
`--gemini`	Gemini CLI	`~/.gemini/settings.json`
`--codex`	OpenAI Codex CLI	`~/.codex/config.toml`
`--vscode`	VS Code (Copilot agent)	`./.vscode/mcp.json` (project-scoped)

Each installer merges into the existing config — it won't clobber other servers or settings. Restart the client afterward.

OpenRouter (any model)

The clients above are MCP hosts — they connect to this server for you. To drive the tools with an OpenRouter model instead, the server ships a built-in bridge: it spawns itself in server mode, exposes the tools to the model as function tools, and runs the tool-call loop. This is the client-side pattern from OpenRouter's MCP cookbook, packaged into the binary.

export OPENROUTER_API_KEY=sk-or-...
npx @aibtc/mcp-server@latest bridge "what's the STX balance of SP3...?"

Safety flags (this server moves real funds, so the bridge defaults to nothing extra and lets you constrain it):

Flag	Effect
`--read-only`	Expose only read-only tools (no transfer/swap/deploy/etc.)
`--allow a,b`	Force-allow specific tool names (added to the set)
`--block a,b`	Force-remove specific tool names (wins over `--allow`)
`--max-spend-ustx <n>` / `--max-spend-sats <n>`	Cap spend via the server's spend-limit rail (enforced before signing)
`--list-tools`	Print the exposed tool set and exit (no API key needed)
`--model <id>`	OpenRouter model (default `anthropic/claude-3.5-haiku`)
`--network <net>`	`mainnet` or `testnet` (default `mainnet`)
`--max-turns <n>`	Tool-call loop cap (default 10)

# Preview what a read-only session would expose, no key needed:
npx @aibtc/mcp-server@latest bridge --read-only --list-tools

# Read-only chat, plus one explicitly allowed write tool:
npx @aibtc/mcp-server@latest bridge --read-only --allow transfer_stx "send 1 STX to SP3..."

Before any agent loop runs (and on --list-tools), the bridge prints a compact safety receipt to stderr — network, read-only mode, exposed/write/blocked tool counts, the session spend cap, and the number of known x402 endpoints — so the configured execution boundaries are visible up front. It reports boundaries only; it never claims any value moved.

The allowlist is re-enforced at execution time, so a model can never call a tool outside the exposed set. Any MCP-capable agent framework (@openrouter/agent, OpenAI Agents SDK, Claude Agent SDK) can also point at this server directly — the bridge is for driving it through OpenRouter's raw API without adopting a framework.

Testnet Mode

Add --testnet to any install command:

npx @aibtc/mcp-server@latest --install --testnet            # Claude Code, testnet
npx @aibtc/mcp-server@latest --install --cursor --testnet   # Cursor, testnet

Why npx? Using npx @aibtc/mcp-server@latest ensures you always get the newest version automatically. Global installs (npm install -g) won't auto-update.

Tool Profiles

Every tool definition is loaded into the model's context, so --install writes AIBTC_TOOLS=core: a lean core of 24 tools: wallet (including wallet_rotate_password; wallet_export is in the wallet group so the mnemonic isn't one call away), balances, STX/BTC/sBTC transfers, x402 (list_x402_endpoints, probe_x402_endpoint, execute_x402_endpoint) and earning (earning_opportunities, bounty_list/get/submit, identity_register).

Add groups with AIBTC_TOOLS=core,defi,ordinals in the server's env (the core is always included), or load everything with AIBTC_TOOLS=all / --profile full. If AIBTC_TOOLS is not set at all, every tool is loaded, so configs written by earlier versions keep all their tools:

npx @aibtc/mcp-server@latest --install --profile full   # writes AIBTC_TOOLS=all

Group	Tools
`wallet`	Wallet management extras, encrypted credential store
`stacks`	Stacks transactions, contracts, tokens, NFTs, chain queries, nonce tools
`sbtc`	sBTC deposit/withdraw, Styx BTC→sBTC
`bitcoin`	Bitcoin L1 UTXOs, mempool watch
`lightning`	Lightning (Spark) wallet and L402 payments
`stacking`	PoX stacking, dual stacking, StackSpot
`defi`	ALEX, Zest, Bitflow, Jingswap, yield hunter/dashboard, Tenero analytics
`pillar`	Pillar smart wallet
`ordinals`	Inscriptions, runes, PSBT, ordinals marketplace/P2P, taproot multisig
`bns`	BNS names
`identity`	ERC-8004 identity and reputation, message signing
`social`	Nostr, AIBTC inbox
`earn`	Bounty board (create, accept, pay, my views)
`legion`	AIBTC News Legion, At Stake side legions (El Salvador)
`markets`	Stacks prediction market, At Stake market
`dev`	Scaffolding, OpenRouter, settings, inference marketplace, arXiv

The server's instructions list the groups that are off, so the agent can tell you which one to enable. The OpenRouter bridge starts from the full set and narrows it with its own --read-only/--allow/--block flags.

Manual Configuration

If you prefer to configure manually, add the following to your client's config file. The -y flag stops npx from prompting for confirmation.

Claude Code / Claude Desktop / Cursor / Windsurf / Gemini CLI — mcpServers JSON:

{
  "mcpServers": {
    "aibtc": {
      "command": "npx",
      "args": ["-y", "@aibtc/mcp-server@latest"],
      "env": {
        "NETWORK": "mainnet"
      }
    }
  }
}

VS Code (.vscode/mcp.json) — uses a servers key and a typed entry:

{
  "servers": {
    "aibtc": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@aibtc/mcp-server@latest"],
      "env": { "NETWORK": "mainnet" }
    }
  }
}

OpenAI Codex CLI (~/.codex/config.toml) — TOML, not JSON:

[mcp_servers.aibtc]
command = "npx"
args = ["-y", "@aibtc/mcp-server@latest"]

[mcp_servers.aibtc.env]
NETWORK = "mainnet"

Zed (settings.json) — uses a context_servers key:

{
  "context_servers": {
    "aibtc": {
      "source": "custom",
      "command": "npx",
      "args": ["-y", "@aibtc/mcp-server@latest"],
      "env": { "NETWORK": "mainnet" }
    }
  }
}

Cline / Roo Code (VS Code extension) — add the same mcpServers JSON block above via the extension's MCP settings panel (the exact cline_mcp_settings.json path varies by OS and VS Code build).

Any other MCP client works too — point it at npx -y @aibtc/mcp-server@latest over stdio with NETWORK in the env.

Giving Claude a Wallet

--install creates a wallet for you (see Quick Start). If you installed with --no-wallet, configured the client by hand, or want another wallet, the agent can create or import one:

Example Conversation

You: What's your wallet address?

Claude: I don't have a wallet yet. Would you like to assign me one?
        I can either create a fresh wallet or you can import an existing one.

You: Create a new wallet called "agent-wallet"

Claude: What password should I use to protect the wallet?

You: use "secure123password"

Claude: I now have a wallet! My address is ST1ABC...XYZ

        IMPORTANT: Please save this recovery phrase securely:
        "word1 word2 word3 ... word24"

        This phrase will NOT be shown again. It's the only way to recover
        the wallet if the password is forgotten.

You: Send 10 STX to ST2DEF...

Claude: Done! I've sent 10 STX to ST2DEF...
        Transaction: 0x123...

Wallet States

State	What Claude Says	What To Do
No wallet	"I don't have a wallet yet"	Use `wallet_create` or `wallet_import`
Locked	"My wallet is locked"	Use `wallet_unlock` with password
Ready	"My address is ST..."	Claude can perform transactions

Session Management

By default, the wallet auto-locks after 15 minutes
You can change this with wallet_set_timeout (set to 0 to disable)
Use wallet_lock to manually lock the wallet
Use wallet_unlock when you need Claude to transact again

Wallet Storage

Claude's wallets are stored locally on your machine:

~/.aibtc/
├── wallets.json       # Wallet index (names, addresses - no secrets)
├── config.json        # Active wallet, settings
└── wallets/
    └── [wallet-id]/
        └── keystore.json  # Encrypted mnemonic (AES-256-GCM + Scrypt)

Security:

AES-256-GCM encryption with Scrypt key derivation
Password required to unlock
Mnemonics never stored in plaintext
File permissions set to owner-only (0600)

Bitcoin L1 Support

Each wallet automatically derives both a Stacks address and a Bitcoin address from the same mnemonic using BIP39/BIP32 standards.

Derivation Paths (BIP84):

Mainnet: m/84'/0'/0'/0/0 (Bitcoin coin type 0)
Testnet: m/84'/1'/0'/0/0 (Bitcoin testnet coin type 1)

Address Format:

Mainnet: bc1q... (Native SegWit P2WPKH)
Testnet: tb1q... (Native SegWit P2WPKH)

Capabilities:

Full Bitcoin L1 transaction support (send BTC)
Balance and UTXO queries via mempool.space API
Fee estimation (fast/medium/slow)
P2WPKH (native SegWit) transactions for optimal fees

Example:

You: Create a wallet called "my-wallet"
Claude: I've created a wallet with:
        Stacks address: ST1ABC...
        Bitcoin address: bc1q...

You: Send 50000 sats to bc1q...
Claude: Done! Transaction broadcast: abc123...

Both addresses are derived from the same recovery phrase, making it easy to manage both Layer 1 (Bitcoin) and Layer 2 (Stacks) assets.

Configuration

Environment Variable	Description	Default
`NETWORK`	`mainnet` or `testnet`	`mainnet`
`AIBTC_TOOLS`	`core`, `core,<group,...>`, or `all` (see Tool Profiles). `--install` writes `core`	all tools when unset
`CLIENT_MNEMONIC`	(Optional) Pre-configured mnemonic	-
`HIRO_API_KEY`	(Optional) Hiro API key for higher rate limits	-
`SPEND_LIMIT_ENABLED`	Set `false` to disable the wallet spending limit	`true`
`SPEND_LIMIT_DAILY_USTX` / `SPEND_LIMIT_SESSION_USTX`	STX spend cap per day / per unlock (micro-STX)	`50000000` (50 STX)
`SPEND_LIMIT_DAILY_SATS` / `SPEND_LIMIT_SESSION_SATS`	BTC spend cap per day / per unlock (sats)	`50000`
`AIBTC_ALLOW_BLIND_SIGN`	Allow `schnorr_sign_digest` to sign raw digests (a signed sighash spends outside the spending limit)	off

Note on NETWORK: The --install command writes NETWORK=mainnet by default (pass --testnet to use testnet). If you omit NETWORK from your config entirely, the runtime fallback is also mainnet.

Note on spending limits: A default-on safety rail meters every STX, sBTC and BTC spend (transfers, contract calls, sponsored transactions, x402/L402 auto-payments, Bitcoin broadcasts, psbt_sign) against a cumulative per-session and per-day cap, so a single bad instruction or a malicious endpoint can't drain the wallet. A spend over the cap is blocked before it is signed or broadcast, and the agent is told to ask you. Raise the caps via the env vars above, or disable with SPEND_LIMIT_ENABLED=false. The limit runs inside the server: it does not contain an agent with shell access to your machine, so keep spend tools out of your client's auto-approve list. See SECURITY.md.

Note: CLIENT_MNEMONIC is optional. The recommended approach is to let Claude create its own wallet. HIRO_API_KEY is optional but recommended for production use — without it, you may hit Hiro's public rate limits (429 responses). Get a key at platform.hiro.so.

Security Notes

Claude's wallet is stored encrypted on YOUR machine
Password is never stored - only the encrypted keystore
Mnemonics shown only once at creation
Auto-lock after 15 minutes (configurable)
Transactions signed locally before broadcast
Spending limit (default-on): outbound spends are capped per session and per day so a single bad instruction can't drain the wallet — see Configuration
Secret-scanning pre-commit hook: contributors get a hook (auto-installed via npm install) that blocks committing a seed phrase or private key
For mainnet: Fund with small amounts first

See SECURITY.md for the full wallet-key protection model and key-leak recovery steps.

Advanced: Pre-configured Mnemonic

For automated setups where Claude needs immediate wallet access, add the CLIENT_MNEMONIC environment variable to your MCP server config (in ~/.claude.json for Claude Code, or claude_desktop_config.json for Claude Desktop):

{
  "mcpServers": {
    "aibtc": {
      "command": "npx",
      "args": ["@aibtc/mcp-server@latest"],
      "env": {
        "CLIENT_MNEMONIC": "your twenty four word mnemonic phrase",
        "NETWORK": "testnet"
      }
    }
  }
}

This bypasses the wallet creation flow - Claude has immediate access to transact.
