  • scan_signalsRanked cross-signal feed of CoinBucha's leading, non-price Bitcoin indicators.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    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 }. 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.

  • get_daily_brewThe day's machine-readable digest of the whole signal set — the CoinBucha Daily Brew.No findings

    Why it is in this group

    • The name "get_daily_brew" says "get": a word for reading.
    Description, as the server wrote it
    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.

  • get_etf_flowsRETIRED: this tool is no longer advertised and serves no flow figures.No findings

    Why it is in this group

    • The name "get_etf_flows" says "get": a word for reading.
    Description, as the server wrote it
    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.

  • get_hiring_signalHiring velocity across tracked Bitcoin and crypto-infrastructure employers, counted from their live ATS boards.No findings

    Why it is in this group

    • The name "get_hiring_signal" says "get": a word for reading.
    Description, as the server wrote it
    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 }. 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.

  • get_network_signalBitcoin network hashrate level and trend, derived from difficulty (expected, 2016-block epoch).No findings

    Why it is in this group

    • The name "get_network_signal" says "get": a word for reading.
    Description, as the server wrote it
    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 }. 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.

  • get_signal_historyDated strength history for one CoinBucha signal, newest first.No findings

    Why it is in this group

    • The name "get_signal_history" says "get": a word for reading.
    Description, as the server wrote it
    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. Beyond that window: a cut answer carries `more`, naming the per-call x402 route /api/paid/signal-history (every signal's full series in one call, USDC) and whether it is open now; or data_contract.bulk_url names the free 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.

  • get_sovereign_reservesNation-state Bitcoin holdings, ranked largest first.No findings

    Why it is in this group

    • The name "get_sovereign_reserves" says "get": a word for reading.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "get_treasury_holdings" says "get": a word for reading.
    Description, as the server wrote it
    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 }. 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.

  • sovereign_diffWhat changed between two frozen, immutable sovereign-reserve snapshots.No findings

    Why it is in this group

    • The name "sovereign_diff" says "diff": a word for reading.
    Description, as the server wrote it
    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. The whole frozen series in one call: the per-call x402 route /api/paid/sovereign-snapshots (USDC); the per-date snapshot files stay free. 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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
