Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add instructions/ruby0606/mcp-earthquake-server/copilot-instructionsgit clone --depth 1 https://github.com/ruby0606/mcp-earthquake-serverWhat it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.01021 | $0.01021 |
| Opus 5 | $0.00511 | $0.00511 |
| Sonnet 5 | $0.00204 | $0.00204 |
| Haiku 4.5 | $0.00102 | $0.00102 |
Grade C, and why
mcp-earthquake-server copilot-instructions.md scanned grade C with 1 finding against 26 rules in 11 categories โ prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency โ measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

PROJECT STATUS: PRODUCTION READY
COPILOT CONTEXT:
When working on this project:
- Data Sources: Always respect attribution requirements and usage terms
- Global Scope: Support worldwide coordinates, no geographic restrictions
- Error Handling: Implement proper validation for seismological parameters
- Performance: Consider API rate limits and caching strategies
- Scientific Accuracy: Cross-reference multiple sources when possible
- Emergency Use: Note this is for research only, not emergency response
- Data Integrity: Always use real API calls, don't use mock data
COMPLETED MILESTONES:
- Project Requirements Clarified - Global earthquake monitoring via MCP server
- Project Scaffolded - Complete TypeScript MCP server implementation
- Multi-source Integration - IRIS + USGS + GNSS + InSAR data providers
- Global Coverage Implemented - Worldwide earthquake monitoring (no geographic limits)
- Code Review Completed - All critical issues resolved
- Comprehensive Documentation - README, Developer Setup, Research Guide
- Data Attribution Added - Proper citations and usage terms for all sources
- GitHub Repository Live - https://github.com/ruby0606/mcp-earthquake-server
- Testing Validated - Real data retrieval confirmed from all sources
- Production Deployment Ready - MIT licensed, open source distribution
๐ฏ MCP EARTHQUAKE MONITORING SERVER
Repository: https://github.com/ruby0606/mcp-earthquake-server
This is a production-ready Model Context Protocol server providing AI systems with direct access to authoritative earthquake data sources, eliminating hallucinations and ensuring scientific accuracy.

Core Implementation: src/index.ts - Main MCP server with 10 earthquake monitoring tools
Data Providers:
src/providers/iris-provider.ts- IRIS seismological data (FIXED: text format parsing)src/providers/usgs-provider.ts- USGS real-time earthquake feedssrc/providers/gnss-provider.ts- GPS/GNSS crustal deformation datasrc/providers/insar-provider.ts- Satellite radar interferometry data
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mcp-earthquake-server copilot-instructions.md is an instructions file published in the GitHub repository ruby0606/mcp-earthquake-server (1 stars, last pushed 1y ago), licensed MIT. It adds 1,021 tokens to every session, about $0.0051 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
