environment-mcp
MCP server that provides tools to access Google Maps Environment APIs for air quality, pollen, and weather data, enabling queries like current conditions, forecasts, and history.

air_quality_current_conditionsGoogle Air Quality API: current conditions at a location (hourly indexes, optional pollutants via extraComputations). POST body matches https://developers.google.com/maps/documentation/air-quality/reference/rest/v1/currentConditions/lookup — requires `location` with latitude and longitude; other opt…
air_quality_forecastGoogle Air Quality API: hourly forecast for a time range or specific hour. POST body matches https://developers.google.com/maps/documentation/air-quality/reference/rest/v1/forecast/lookup — requires `location`; use `period` (startTime/endTime), `dateTime`, or `hours` per API docs.
air_quality_historyGoogle Air Quality API: historical hourly data. POST body matches https://developers.google.com/maps/documentation/air-quality/reference/rest/v1/history/lookup — requires `location`; use `period`, `dateTime`, or `hours` (1–720) per API docs.
pollen_forecastGoogle Pollen API: daily pollen forecast (1–5 days) at a location. See https://developers.google.com/maps/documentation/pollen/forecast
weather_current_conditionsGoogle Weather API: current conditions at a location. See https://developers.google.com/maps/documentation/weather/current-conditions
weather_forecast_daysGoogle Weather API: up to 10 days of daily forecast. See https://developers.google.com/maps/documentation/weather/daily-forecast
weather_forecast_hoursGoogle Weather API: up to 240 hours of hourly forecast. See https://developers.google.com/maps/documentation/weather/hourly-forecast
weather_history_hoursGoogle Weather API: up to 24 hours of historical hourly weather. See https://developers.google.com/maps/documentation/weather/hourly-history
weather_public_alertsGoogle Weather API: public weather alerts intersecting a location. See https://developers.google.com/maps/documentation/weather/weather-alerts
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
GOOGLE_ENVIRONMENT_API_KEYAlternatively use .GOOGLE_MAPS_API_KEYexport ="your-key"Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
9/9 tools missing one or more hints — air_quality_current_conditions (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); air_quality_forecast (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); air_quality_history (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +6 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
Only 0/9 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/9 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
