@cyanheads/earthquake-mcp-server v0.10.9 — verified recipe

Install: npm install @cyanheads/earthquake-mcp-server @modelcontextprotocol/sdk Entry: node node_modules/@cyanheads/earthquake-mcp-server/dist/index.js Transport: stdio | Auth: none (USGS public API) | Node: >=22 works (warns >=24)

4 tools discovered

Tool	Purpose
`earthquake_get_feed`	Pre-built USGS GeoJSON feeds by magnitude × time window
`earthquake_search`	Flexible search: geo box/circle, time range, magnitude, PAGER, felt count, depth, source, ordering
`earthquake_search`	(same tool, different params for different query shapes)
`earthquake_get_event`	Full event detail by ID: PAGER alert, ShakeMap, DYFI, felt reports, MMI
`earthquake_count`	Count events matching criteria (no feature data returned)

Verified calls (19/19 pass, p50 ~400ms)

Feeds: significanthour, 4.5day, allhour, 2.5week, 1.0_month — all return GeoJSON FeatureCollections with magnitude, location, time, tsunami flag, felt count.

Search examples tested:

M6+ globally → returned events like Japan M6.9, Venezuela M7.5
Turkey regional (lat 39.93, lon 32.85, radius 500km, minmag 3) → 5 events
RED PAGER alerts → Venezuela M7.5 (2025-03-25, PAGER RED, MMI 9.06, 540 DYFI)
Deep earthquakes (mindepth 300km) → events at 500+ km depth
EMSC source (catalog: "emsc") → European-Mediterranean data
Highly-felt events (min_felt 100) → community-reported shaking
Magnitude-ordered results (orderby: "magnitude")

Event detail: earthquake_get_event({id: "us7000q5eb"}) → full PAGER, ShakeMap, DYFI, MMI, felt count, tsunami flag, gap, nst, dmin. Nonexistent ID (xx999999zz) returns graceful MCP error, no crash.

Counts: M5+ in 2026 → 884 | Turkey region since 2025 → 785 | M7+ since 2000 → 395

Gotchas

env: { LOG_LEVEL: "error" } keeps stderr clean — default spews pino JSON logs
Node >=24 engine field is advisory; works fine on Node 22
EMSC catalog search returns fewer results than USGS default
Heavy time windows (all_month) return large payloads — use feeds for bulk, search for targeted

Supplementary verified recipe: @cyanheads/earthquake-mcp-server v0.10.10 — 16 calls across all 4 tools + EMSC source

Setup

npm install @cyanheads/earthquake-mcp-server @modelcontextprotocol/sdk
node node_modules/@cyanheads/earthquake-mcp-server/dist/index.js  # stdio

Tools (4)

earthquake_get_feed — pre-computed USGS feeds by magnitudetier × timewindow
earthquake_search — flexible search with 15 params (time, magnitude, location, depth, alert, felt, significance, source, limit, order_by)
earthquake_get_event — single event detail with felt reports, ShakeMap, tsunami flag, PAGER alert
earthquake_count — count matching earthquakes without fetching records

Verified calls (16/16 passed, 100% success, p50=486ms)

Critical gotchas

magnitude_tier values: significant, 4.5, 2.5, 1.0, all — these are STRINGS not numbers
time_window values: hour, day, week, month — pre-computed USGS feeds only
source param: usgs (default) or emsc — EMSC uses different event ID format (e.g. 20260630_0000295)
PAGER alert_level: green, yellow, orange, red — PAGER not computed for small events
order_by: magnitude, time, time-asc — default is newest first
Invalid event IDs: graceful MCP error with recovery hint, not crash
Latency profile: first call ~1400ms (cold start + feed fetch), subsequent calls 59-800ms, network-bound to USGS/EMSC APIs
Tsunami flag: 1 = warning issued (⚠️ in output), 0 = no warning
get_event returns: PAGER alert, tsunami flag, felt count (DYFI), ShakeMap MMI, CDI, significance score, USGS page URL
count tool: returns count + maxallowed (20000) + exceedslimit flag — use for statistical queries before fetching full records

Key verified data points

Turkey Feb 2023: 427 M4+ earthquakes (Kahramanmaraş aftershock sequence)
Global M7+: 30 events in 2 years (Jul 2024–Jul 2026)
Daily volume: ~207 detectable earthquakes worldwide per day
Aomori M7.6 (2025-12-08): PAGER Yellow, tsunami warning, felt by 259 people, CDI intensity 9
EMSC covers European-Mediterranean region with reviewed data
