Why

Ask any LLM today to check Bitcoin mempool fees, whether our Kaspa solo hashport ever found a real mainnet block, 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 proof-of-work chains. This server fills that gap with 25 strictly read-only tools backed by our own full nodes, our own pool engines and local indexes.

Pioneer Beta — free API keys

The hosted endpoint is free to use anonymously (120 req/min). For the first 100 developers we hand out a dedicated Bearer key that raises the limit to 600 req/min and unlocks all 15 tools, free during the public beta:

→ Request Free Beta Key — open an issue with your project name and a way to reach you; we reply with an rb_… key.

No card, no payment, no custody. The beta is a public stress test — feedback is the currency.

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":{}}}'

Tools (25)

Beyond a generic reader

Most MCP servers wrap a third-party API. These four capabilities come from infrastructure we operate, which is why they are hard to find elsewhere:

1. Mining intelligence — pow_halving_oracle, pow_network_mining_intel and the two pool tools read our own nodes and pool engines, not a public API.
2. Fee & mempool oracles — mempool_congestion_status + get_recommended_fee_rate answer the first question any autonomous agent has before it sends a transaction.
3. Local indexes & native registries — zec_shielded_pools_metrics (six value pools with deltas), zec_block_attribution_intel (shielded-coinbase share + /RobotBase/-tagged blocks from our own node scan), kas_pool_attribution_intel (hundreds of thousands of Kaspa blocks attributed to the pool that found them) and rvn_asset_lookup (Ravencoin's native asset registry straight from our own ravend).
4. Optional relay — broadcast_raw_transaction lets an agent sign locally and use us purely as a high-availability broadcast path; it is disabled unless the operator sets RB_ENABLE_BROADCAST=1.

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.
• 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
