Signal-first Bitcoin intelligence over MCP. Surfaces leading, non-price indicators — sovereign reserve adoption, Bitcoin/crypto-infra hiring velocity, and network hashrate trend — each with a 0–100 strength, a direction (tailwind/headwind/neutral), a one-line rationale, and primary sources. Tools: scan_signals, get_hiring_signal, get_sovereign_reserves, get_network_signal, get_daily_brew. Resource: coinbucha://methodology. Information, not financial advice.
Scored across 9 tools
Most tools target distinct resources (sovereign reserves, treasury holdings, hiring, network hashrate, daily digest, history, diff), but get_daily_brew, scan_signals, and get_signal_history all return aggreagated signal data at different granularities, which could cause misselection. The retired get_etf_flows is clearly marked but still occupies the surface. Descriptions largely disambiguate the overlap.
Seven of nine tools follow a clean get_<noun> pattern (get_daily_brew, get_etf_flows, get_hiring_signal, get_network_signal, get_signal_history, get_sovereign_reserves, get_treasury_holdings). scan_signals and sovereign_diff deviate with verb-first/compound styles, but remain readable and predictable overall.
Nine tools is well-scoped for a Bitcoin-signals server and each active tool serves a plausible purpose. The retired get_etf_flows is dead weight that adds surface area without functionality, a minor deduction.
Coverage is broad: aggregated feed, digest, per-signal history, sovereign reserves, treasury holdings, hiring, network, and snapshot diffing form a coherent observational surface. The obvious gap is ETF flows, which is explicitly retired, and there is no standalone price or market-data tool, but core workflows are covered.
The day's machine-readable digest of the whole signal set — the CoinBucha Daily Brew. Takes no arguments. Returns { date, btc_price_usd, headline, signals_summary[], attribution, source_terms }, one summary line per signal with its strength, direction and one-line why. Example: {}. CoinGecko values carry attribution: "Powered by CoinGecko" and source_terms. Information, not financial advice. Every answer carries data_contract { source, as_of, status, corrections_url, license }. This server answers bounded questions, one question, one answer; for bulk, history, backfills and scheduled pulls use the CSVs and datapackage.json at https://coinbucha.com/data.

RETIRED: this tool is no longer advertised and serves no flow figures. No spot-Bitcoin-ETF flow source is available that is both key-free and permitted to redistribute, so CoinBucha never had a licensed figure to serve here. It remains callable so existing integrations do not break: it takes no arguments and returns { available: false, status, as_of, date_basis, unit, note, disclaimer }, stating the absence explicitly. Read that absence as absent — never as a zero flow. For live signals use scan_signals, get_sovereign_reserves, get_treasury_holdings, get_hiring_signal, get_network_signal or get_daily_brew. Example: {}. Information, not financial advice. Every answer carries data_contract { source, as_of, status, corrections_url, license }. This server answers bounded questions, one question, one answer; for bulk, history, backfills and scheduled pulls use the CSVs and datapackage.json at https://coinbucha.com/data.

Hiring velocity across tracked Bitcoin and crypto-infrastructure employers, counted from their live ATS boards. Returns { as_of, companies[], note, why, disclaimer }; each company carries company, ticker, category, ats, careers_url, open_roles, open_roles_30d_ago, open_roles_90d_ago and the derived delta_30d, delta_90d and pct_30d. Example: {"company": "coinbase"} for one employer, or {} for every employer tracked. When a company filter matches no tracked employer the response adds coverage_note and tracked_count, saying that the name is outside the tracked set — a limit of coverage, not a finding about whether that company is hiring. Information, not financial advice. Every answer carries data_contract { source, as_of, status, corrections_url, license }.

Bitcoin network hashrate level and trend, derived from difficulty (expected, 2016-block epoch). hashrate_eh = difficulty × 2^32 / 600 s for the epoch in force, read from block headers — an expected rate, not a measured one. Takes no arguments. Returns { as_of, hashrate_eh (exahashes per second), pct_30d, pct_90d, hashrate_source, basis, difficulty, difficulty_height, difficulty_source_url, why, disclaimer }. Example: {}. Information, not financial advice. Every answer carries data_contract { source, as_of, status, corrections_url, license }.

Dated strength history for one CoinBucha signal, newest first. Returns { as_of, signal_type, title, unit, count, points[], truncated, available_points, tier_window_points, freshness, why, disclaimer, cite }, where each point carries date, signal_strength (0-100) and direction (tailwind | headwind | neutral). Example: {"signal_type": "network_hashrate", "days": 30}. signal_type is one of sovereign_adoption, hiring_velocity, corporate_treasury, network_hashrate. Anonymous and free-tier callers receive the most recent points only and are told so by truncated and available_points; no figure is ever altered or interpolated to fit a window. A history question beyond that window is a bulk question: data_contract.bulk_url names the CSV of the signal's dated figures. Observational data; information, not financial advice. Every answer carries data_contract { source, as_of, status, corrections_url, license }. This server answers bounded questions, one question, one answer; for bulk, history, backfills and scheduled pulls use the CSVs and datapackage.json at https://coinbucha.com/data.
| Name | Required | Description | Default |
|---|---|---|---|
| days | No | How many of the most recent dated points to return (1-90) | |
| signal_type | Yes | Which signal's history to return |
Nation-state Bitcoin holdings, ranked largest first. Returns { as_of, btc_price_usd, count, sovereigns[], disclaimer, attribution, source_terms }; each row carries country_name, country_code, holdings_btc, status, tier (1 = largest holders), framework, sources[], its own as_of, and source_quality (primary = confirmed against the state's own publication; secondary = reported, not confirmed at source — derived from that row's sources[]). Filter by country name or ISO code, or by tier. Example: {"country": "US"} or {"tier": 1} — call with {} for the full ranking. CoinGecko values carry attribution: "Powered by CoinGecko" and source_terms. Information, not financial advice. Every answer carries data_contract { source, as_of, status, corrections_url, license }. This server answers bounded questions, one question, one answer; for bulk, history, backfills and scheduled pulls use the CSVs and datapackage.json at https://coinbucha.com/data.

Bitcoin held on the balance sheets of tracked public companies, in aggregate and by largest holder. Takes no arguments. Returns { as_of, total_btc, company_count, total_value_usd, top[], why, disclaimer, attribution, source_terms }, where top[] lists the largest holders as { name, symbol, btc }. Example: {}. CoinGecko values carry attribution: "Powered by CoinGecko" and source_terms. Information, not financial advice. Every answer carries data_contract { source, as_of, status, corrections_url, license }.

Ranked cross-signal feed of CoinBucha's leading, non-price Bitcoin indicators. Returns { as_of, btc_price_usd, count, signals[], disclaimer, attribution, source_terms }, where each signal carries id, type, title, value, unit, signal_strength (0-100), direction (tailwind | headwind | neutral), a one-line why, sources[] and its own as_of. Optional filters narrow by strength, direction or signal type. Example: {"min_strength": 70, "direction": "tailwind"} — call with {} for the full ranked list. CoinGecko values carry attribution: "Powered by CoinGecko" and source_terms. Observational data; information, not financial advice. Every answer carries data_contract { source, as_of, status, corrections_url, license }.

What changed between two frozen, immutable sovereign-reserve snapshots. Takes optional { from, to } snapshot dates (YYYY-MM-DD); defaults to the two newest. Returns { status, as_of, from, to, counts, added[], removed[], changed[], envelope[], disclaimer, cite }, where each changed row carries country_code, country_name, source_quality { from, to } and changes[] of { field, basis (reported | derived), from, to }. With fewer than two snapshots it returns status "insufficient_snapshots" and diff: null — not an empty diff. Example: {"from": "2026-09-04", "to": "2026-10-01"}. CoinGecko values carry attribution: "Powered by CoinGecko" and source_terms. Information, not financial advice. Every answer carries data_contract { source, as_of, status, corrections_url, license }.
