Looks up a Bitcoin address: balance, totals, recent transactions and counterparties

Community-packaged from github.com/osintverse-community/btc-address: the registry's community pins the upstream release; the tool is its authors' work. Maintain that project? Claim this package.

Run

Through ot mcp, an agent calls run_tool with this; ot asks you before anything that goes online or touches a target. Set it up: ot mcp install claude (or cursor, vscode, codex, gemini).

{"tool":"osintverse-community/btc-address","target":"1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa","input_type":"crypto_address"}

Or just say: "Run osintverse-community/btc-address on 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa with OTInstaller." The registry's read-only MCP server at api.otinstaller.com/mcp can find tools without installing anything.

ot run osintverse-community/btc-address --address 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa --format table
ot install osintverse-community/btc-address

Docker image in a read-only container · talks to blockstream.info · no key · up to 1 min. The first ot run installs the tool after asking once. The example value is the registry's own test input, so this command has run. Drop --format table for JSON.
