01 · Install Socrata MCP Server

before you install - you'll need

Set MCP_TRANSPORT_TYPE, MCP_LOG_LEVEL before connecting.

Claude Code

claude mcp add cyanheads-socrata-mcp-server --transport http https://socrata.caseyjhand.com/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "cyanheads-socrata-mcp-server": {
      "url": "https://socrata.caseyjhand.com/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

03 · What Socrata MCP Server can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can list known Socrata-powered government open-data portals with domain, organization name, and approximate dataset count, search for datasets across all Socrata portals or scope to one portal via the Discovery API, fetch full metadata and typed column schema for a dataset by ID - required before writing SoQL queries, and execute a SoQL query against any dataset: search, select, where, group, having, order, with DataCanvas spillover.
