# Solcast — MCP server on mcp.ai
> Connect your Solcast account and use 6 tools for analytics straight from your AI agent. Connect with your own API key. Solar resource assessment and forecasting data for irradiance and PV power, globally.

By: mcp.ai · official
Page: https://mcp.ai/solcast

## Connect (MCP protocol)
Remote MCP endpoint (HTTP, streamable): https://api.mcp.ai/p_solcast?ms=1787291520000
Add it as a custom/remote MCP connector, then authenticate when prompted.

## REST API (no MCP client required)
Every tool is also a REST endpoint, authed with a workspace API key.
Discover: GET https://api.mcp.ai/api/solcast/_endpoints   # public; lists every endpoint
Call:     POST https://api.mcp.ai/api/solcast/<endpoint>
  Authorization: Bearer sk_live_…   # create one at https://mcp.ai/settings/api-keys
  Content-Type: application/json
  Body: { …args }   →   { "ok": true, "tool": "<id>", "result": { … } }

## Tools
- solcast_get_data_historic_radiation_and_weather(end?: string, tilt?: number, start: string, format?: string, period?: string, azimuth?: number, duration?: string, latitude: number, longitude: number, time_zone?: string, array_type?: string, terrain_shading?: boolean, output_parameters?: string[]) — Tool to get historical irradiance and weather estimated actuals for a requested location. Use when you need historical solar radiation and weather data from 2007-01-01 to 7 days ago, for up to 31 days
- solcast_get_resources_pv_power_site(resource_id: string) — Tool to retrieve a specific PV power resource by its unique identifier. Use when you need to fetch complete resource configuration including capacity, orientation, tracking, and derating parameters.
- solcast_get_resources_pv_power_sites(entitlement?: string) — Tool to list PV power resources available to authenticated user. Use when you need to retrieve the list of PV power sites with optional filtering by entitlement level.
- solcast_patch_resources_pv_power_site(name?: string, tilt?: number, azimuth?: number, capacity?: number, latitude?: number, longitude?: number, capacity_dc?: number, entitlement?: string, module_type?: string, pvrow_width?: number, resource_id: string, install_date?: string, pvrow_height?: number, terrain_slope?: number, tracking_type?: string, bifacial_system?: boolean, terrain_azimuth?: number, grid_export_limit?: number, bifaciality_factor?: number, confirmed_metadata?: string, site_ground_albedo?: number, derating_age_system?: number, derating_temp_module?: number, dust_soiling_average?: number[], tracker_axis_azimuth?: number, derating_other_system?: number, ground_coverage_ratio?: number, tracker_back_tracking?: boolean, tracker_smart_tracking?: boolean, inverter_peak_efficiency?: number, cloudy_zenith_coefficients?: number[], tracker_max_rotation_angle?: number, clearsky_zenith_coefficients?: number[]) — Tool to partially update an existing PV power resource's technical specifications. Use when you need to modify specific resource configuration fields without replacing the entire resource.
