Arcgis Tigard

What Arcgis Tigard does

Arcgis Tigard provides MCP access to City of Tigard, Oregon open geospatial datasets published through ArcGIS. It is intended for agents that need to discover and inspect local GIS layers before retrieving structured records. Covered subject areas include parcels, zoning, parks, and city services.

The Arcgis Tigard MCP server exposes three pack-specific tools. search_datasets finds datasets by keyword and returns identifying details such as the dataset name, summary, record count, owning organization, and Feature Service URL. That URL becomes the input for the other two tools.

How it works

A typical workflow starts with search_datasets, using a term such as parcels or parks. After selecting a result, call layer_info to examine its fields, geometry type, record count, and capabilities. Use query_layer when you need the actual attribute rows and geometry.

Queries support a SQL-like where expression, a comma-separated out_fields list, order_by, limit, and offset. To inspect a sample without narrowing the records, use where="1=1" with out_fields="*". Results from query_layer contain attribute rows and geometry when supplied by the ArcGIS layer.

Setup and configuration

The Arcgis Tigard MCP server can be connected through the Pipeworx streamable HTTP endpoint:

{
  "mcpServers": {
    "arcgis-tigard": {
      "url": "https://gateway.pipeworx.io/arcgis-tigard/mcp"
    }
  }
}

It can also run locally over stdio with the published package:

{
  "mcpServers": {
    "arcgis-tigard": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-arcgis-tigard"]
    }
  }
}

The local mode does not require a Pipeworx account and exposes only this pack's tools. The gateway endpoint adds shared Pipeworx meta-tools, including ask_pipeworx, discover_tools, search_within, and memory-related tools.

Tools and capabilities

• Search Tigard GIS datasets by keyword.
• Retrieve dataset summaries, ownership, counts, and service URLs.
• Inspect layer fields, data types, geometry, record totals, and capabilities.
• Query Feature Service or Map Service layers by URL.
• Filter, sort, paginate, and select fields in query results.
• Return GIS attribute rows with geometry.

Limitations and notes

Arcgis Tigard is an independent, unofficial integration and is not affiliated with, endorsed by, or published by the City of Tigard or the upstream ArcGIS provider. query_layer and layer_info require a layer URL, so dataset discovery normally comes first. The gateway connection lists shared Pipeworx tools in addition to the three pack tools; the local stdio connection does not. The available data and layer behavior depend on the City of Tigard ArcGIS services.
