About seismic-mcp
seismic-mcp is an MCP server for querying earthquake reports from 20 seismic agencies. It reconciles reports across sources and highlights differences in magnitude, location, and depth for research and situational awareness; it is not an early-warning system.
Key features
- 01Parallel queries to 20 seismic agencies
- 02Cross-agency event matching
- 03Prime-report selection
- 04Magnitude, location, and depth discrepancy detection
- 0560-second TTL cache
- 06HTTP interface with map and comparison view
Use cases
- 01Review reports from multiple agencies for one earthquake
- 02Inspect differences between agency readings
- 03Browse recent events by agency
- 04Manually inspect earthquake reports on a map
MCP support
Exposes seven MCP tools for finding and retrieving events, comparing sources, finding discrepancies, and listing agency information. It also provides the same functionality through an HTTP frontend.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.

Details
From the project READMEseismic-mcp
A unified Model Context Protocol server for global earthquake data. Queries 20 seismic agencies in parallel; matches cross-agency reports of the same earthquake; surfaces magnitude and location discrepancies so AI agents can see what one feed alone would hide.
Status
Working:
- 20 agencies wired up. FDSN-event: USGS, EMSC, IRIS, INGV, GeoNet, GFZ, NOA, IPGP, NCEDC, SCEDC, ISC, SED, BMKG, NIEP, RESIF, KNMI, NRCAN. Custom (non-FDSN): JMA (Japan), AFAD (Türkiye), IMO (Iceland).
- Cross-agency reconciliation. Spatiotemporal clustering, prime-report selection (local authority > EMSC for Europe > USGS), discrepancy detection (magnitude/location/depth spread). Reviewed bulletins trump preliminary.
- Seven MCP tools:
find_events,get_event,compare_sources,find_discrepancies,list_recent_by_agency,get_agency_info,list_agencies. - TTL cache (60 s) with in-flight de-dup: repeated queries are sub-100 ms.
- 57 unit tests covering parsers, matching, prime-selection, authorities, reconciliation, and cache.
- HTTP frontend for manual inspection: form + Leaflet map + side-by-side compare drawer.
Not yet built: EMSC eventid mapping (cross-references USGS/EMSC IDs for tighter matching), populated known_aliases.json, multi-region per-event authority (KOERI alongside AFAD for Türkiye).
Safety
Reports earthquake data from multiple seismic agencies for research, journalism, situational awareness, and curiosity. It is NOT an early-warning system. All earthquake reports arrive AFTER shaking has already occurred where it was felt. For earthquake preparedness and emergency response, consult official local authorities (USGS ShakeAlert, JMA Earthquake Early Warning, etc.). Preliminary magnitudes and locations are routinely revised by reporting agencies; never make safety decisions based on a single reading.
Run
As an MCP server (Claude Desktop, VS Code, etc.)
Once published to PyPI, no checkout is needed — uvx fetches and runs it:
uvx seismic-mcp
Add to claude_desktop_config.json — Windows path is %APPDATA%\Claude\claude_desktop_config.json, macOS ~/Library/Application Support/Claude/claude_desktop_config.json:
{
"mcpServers": {
"seismic": {
"command": "uvx",
"args": ["seismic-mcp"]
}
}
}
To run from a local checkout instead (development):
uv sync
uv run python server.py
Restart Claude Desktop. The tools appear under the seismic-mcp server in the tools menu.
As a web frontend (manual inspection)
uv run python web.py
Then open http://127.0.0.1:8765/. Same code paths as the MCP server, just exposed over HTTP with a small UI.
Tests
uv run pytest

Comments
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
