About this skill

mcp-google-map — Project Knowledge

Overview

This skill contains everything needed to develop, maintain, and extend the @cablate/mcp-google-map MCP server. Reading these files gives you full context on architecture, API specifics, domain knowledge, and the reasoning behind design decisions.

For the agent skill (how to USE the tools), see skills/google-maps/SKILL.md.


Quick Orientation

Aspect Summary
What MCP server providing Google Maps tools for AI agents
Stack TypeScript, Node.js, Express, MCP SDK, Zod
Tools 18 tools (14 atomic + 4 composite)
Transports stdio, Streamable HTTP, standalone exec CLI
APIs Places API (New), Directions, Geocoding, Elevation, Timezone, Weather, Air Quality, Static Maps, Search Along Route

Reference Files

File Content When to read
references/architecture.md System architecture, 3-layer design, transport modes, tool registration flow, 9-file checklist, code map Start here when onboarding. Also read when adding new tools.
references/google-maps-api-guide.md All Google Maps API endpoints used, pricing, coverage limits, rate limits, common gotchas, Places New vs Legacy When debugging API errors, evaluating new APIs, or checking costs
references/geo-domain-knowledge.md GIS fundamentals — coordinates, distance, geocoding, place types, spatial search, map projection, Japan-specific knowledge When making tool design decisions that involve geographic concepts
references/decisions.md 10 Architecture Decision Records (ADR) with context and rationale When asking "why was X built this way?" or considering changes to existing design

How to Add a New Tool

See references/architecture.md § "9-File Tool Change Checklist" for the complete procedure. Summary:

  1. Create src/tools/maps/<toolName>.ts (NAME, DESCRIPTION, SCHEMA, ACTION)
  2. Register in src/config.ts
  3. Add exec case in src/cli.ts
  4. Add to tests/smoke.test.ts (expectedTools + API call test)
  5. Update README.md (count + table + exec list + project structure)
  6. Update skills/google-maps/SKILL.md (Tool Map)
  7. Update skills/google-maps/references/tools-api.md (params + chaining)
  8. Check server.json and package.json descriptions

When to Update This Skill

Trigger What to update
Architecture change references/architecture.md
New Google Maps API integrated references/google-maps-api-guide.md
New design decision made references/decisions.md (add ADR)
New GIS concept relevant to tools references/geo-domain-knowledge.md
