RobotBase MCP Server

Read-only multi-chain data for AI agents — the first MCP server covering all five classic non-EVM chains: Bitcoin · Monero · Zcash · Dogecoin · Litecoin.

免鉴权 · 无追踪 · 只读 ｜ 面向 AI Agent 的五大经典公链数据接口

Why

Ask any LLM today to check Bitcoin mempool fees, a Monero transaction, or the Zcash shielded-pool supply and it has nowhere to look: the MCP ecosystem is rich for EVM/Solana and nearly empty for the classic non-EVM chains. This server fills that gap with 16 strictly read-only tools backed by full nodes.

Works with Claude Desktop, Cursor, VS Code (remote MCP), and any MCP client supporting Streamable HTTP (2025-06-18). No API key needed.

curl -s https://robotbase.cc/mcp -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call",
       "params":{"name":"btc_fee_estimates","arguments":{}}}'

   MCP server (dependency-free Python, this repo)
            ├── BTC  : Bitcoin Core RPC + electrs (address/tx index)
            ├── XMR  : monerod restricted RPC + whitelisted full-RPC helper
            ├── ZEC  : Zebra RPC (valuePools → shielded-pool supply)
            ├── DOGE : Dogecoin Core RPC
            ├── LTC  : Litecoin Core RPC
            └── meta : gateway service aggregation

Privacy & limits

• No auth for anonymous use; optional X-API-Key header (or ?key=) raises the limit.

• Anonymous 120 req/min per IP; with API key 600 req/min per IP (X-MCP-Plan / X-RateLimit-Limit response headers).

• Audit stores only a truncated SHA-256 of the client IP — never query parameters.

• Read-only: no trading, signing, custody, or write methods. BTC transactions are looked up with txindex; XMR uses a whitelisted method list.

• Responses are trimmed to ~3.8 KB per call to protect LLM context.

Self-hosting (this repo)

server.py is a dependency-free reference implementation that talks to your own nodes. Configure everything with environment variables:

export RB_BIND=0.0.0.0            # bind address (default 127.0.0.1)
export RB_PORT=8090               # listen port
export RB_BTC_RPC_URL=http://127.0.0.1:8332
export RB_BTC_RPC_USER=btcrpc
export RB_BTC_RPC_PASS=...
export RB_BTC_DASHBOARD=http://127.0.0.1:8600/api/node   # optional
export RB_ELECTRS_HOST=127.0.0.1  # electrs for btc_address_summary
export RB_ELECTRS_PORT=50001
export RB_XMR_RPC=http://127.0.0.1:18089/json_rpc
export RB_XMR_HELPER=http://127.0.0.1:18085/rpc           # whitelisted full RPC
export RB_ZEC_BASE=http://127.0.0.1:8080                  # status API with /api/chaininfo
export RB_DOGE_BASE=http://127.0.0.1:8080
export RB_LTC_BASE=http://127.0.0.1:8080
