What Arcgis Delawareco MCP server does

Arcgis Delawareco MCP server gives MCP-compatible clients access to Delaware County, Indiana open geospatial datasets exposed through ArcGIS. The catalog covers areas such as parcels, addresses, zoning, and public works. Agents can first search for a relevant dataset, then use the returned service URL to inspect or query its layer.

The service is an independent, unofficial integration and is not affiliated with, endorsed by, or published by the upstream data provider. It is useful for workflows that need structured county GIS records rather than a general-purpose geospatial search engine.

How it works

A typical request starts with search_datasets, which accepts a keyword and returns matching dataset names, summaries, record counts, owner or organization details, and a Feature Service URL. That URL becomes the input for the other tools.

layer_info describes the selected layer before querying it. The response includes field names and types, geometry type, total record count, and supported capabilities. This helps an agent determine which attributes can be requested and how the layer is structured.

query_layer retrieves rows from an ArcGIS Feature Service or Map Service layer. It supports a SQL-like where expression, comma-separated out_fields, order_by, limit, and offset. Results include attributes and geometry. To inspect sample records, use a condition such as 1=1 together with out_fields set to *.

Setup and configuration

Arcgis Delawareco MCP server can be connected through the hosted endpoint:

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

The hosted connection does not require an account for the first calls. Its endpoint also exposes shared Pipeworx meta-tools in addition to the pack-specific tools. The exact tool scope is reported by the MCP initialize response.

For a local connection, run the package with npx:

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

The local process communicates over stdin and stdout and exposes only this pack's three tools. No environment variables or Pipeworx account are specified for this setup.

Tools and capabilities

Arcgis Delawareco MCP server exposes:

• search_datasets: Finds Delaware County GIS datasets by keyword and returns service URLs for follow-up operations.
• query_layer: Retrieves filtered layer records, selected attributes, and geometry with ordering and pagination controls.
• layer_info: Reports a layer's schema, geometry type, record count, and capabilities.

The hosted gateway can also accept direct HTTP tool calls, while the local package speaks MCP directly. Agents may additionally use the gateway's ask_pipeworx routing tool when connected through the hosted endpoint.

Limitations and notes

This integration is limited to the Delaware County, Indiana ArcGIS data exposed by the provider. It does not document write or mutation operations; the listed tools search, inspect, and query data. Results depend on the availability and schema of each ArcGIS service.

The hosted endpoint lists shared gateway tools alongside the three pack tools, so its displayed tool count is larger than the local package's count. Use the local stdio option when only the Delaware County tools are wanted, or use the hosted endpoint when gateway routing is useful. The package is licensed under MIT.
