feat: add MCP server for GitHub Copilot integration with deck.gl/luma.gl ecosystem

[Copilot]

Adds a specification-compliant MCP (Model Context Protocol) server so organizations can expose strata's AI utilities to GitHub Copilot and any MCP-capable assistant via a single org-level config.

New: src/mcp/

• tools.ts — 5 tool definitions wrapping existing pure AI utilities:
  • geocode_location → lng/lat + deck.gl view state via Nominatim
  • calculate_date_range / parse_relative_date → Unix ms timestamps from explicit or relative date expressions
  • get_activities_info → spatiotemporal activity summary + suggested map view
  • resolve_timestamps → resolves relative date strings in noodles ProjectModification[] to concrete timestamps
• server.ts — JSON-RPC 2.0 over stdio; implements initialize, tools/list, tools/call
• index.ts — type exports for consumers embedding tool definitions directly

Package changes

• bin.strata-mcp → ./dist/mcp/server.js — runnable as npx --package=@new-heat/strata strata-mcp
• exports["./mcp"] + typesVersions.mcp subpath added
• @types/node added to devDependencies (scoped via /// <reference types="node" /> in server.ts only)

Org config

.github/copilot/mcp.json — the only file organizations need to copy:

{
  "mcpServers": {
    "strata": {
      "command": "npx",
      "args": ["--yes", "--package=@new-heat/strata", "strata-mcp"]
    }
  }
}

No new runtime dependencies. All 5 tools have unit tests (25 total).

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• npm.duckdb.org
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node /home/REDACTED/work/strata/strata/node_modules/.bin/node-pre-gyp install --fallback-to-build (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
