Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/help.opportunityzones.www%2Fopportunityzones-help/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Is this address in an Opportunity Zone?
Geocodes a US street address (Census Bureau geocoder, falling back to OpenStreetMap; tract assignment by the FCC Census Block API) and returns its 2018 Opportunity Zone status (2010 tract), its status for the 2027 designation round (2020 tract: eligible, nominated or certified, with source), the rural flags, and Census ACS tract statistics.

latrequiredlonrequiredOne census tract's Opportunity Zone record
Status for an 11-digit census tract GEOID. A 2010 GEOID is checked against the 2018 designations and a 2020 GEOID against the 2027 round; many GEOIDs exist in both vintages. If you already geocoded a property, pass geoid_2010 and geoid_2020 instead of geoid.

83% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
Declare a GitHub repository with a README, or serve resource_documentation in the OAuth protected-resource metadata.
A hosted service is used under its provider's terms, so no license is expected here. This check is left out of the percentage.
