btc-public-data

Local MCP server plus CLI wrapping public Bitcoin APIs. No keys. No private data.

Eight tools, same interface for the CLI and MCP tools/list / tools/call:

  • get_fees — mempool.space recommended sat/vB

  • get_mempool — backlog count, vsize, total fees

  • get_hashrate — network hashrate and difficulty

  • get_network — tip height from mempool.space and Blockstream, difficulty, prices

  • get_tx — Blockstream public tx summary

  • get_address — Blockstream watch-only address stats

  • get_lightning — Lightning nodes, channels, capacity, typical fees

  • snapshot — one-call dashboard

Second source is Blockstream Esplora so tip / tx / address can be checked independently. HTTP GETs use a 15s TTL cache and retry 429 / 5xx.

Run

bun src/cli.ts list
bun src/cli.ts snapshot
bun src/cli.ts get_fees
bun src/server.ts
bun test
