What is the HUD Fair Market Rents MCP Server?
Connect directly to the U.S. Department of Housing and Urban Development (HUD) API to retrieve critical housing and economic data through natural conversation. This server provides comprehensive access to Fair Market Rents (FMR) and Income Limits (IL) across the United States.
What you can do
- Geographic Discovery — List all states, counties, and metropolitan areas with their corresponding FIPS and CBSA codes.
- Fair Market Rents (FMR) — Fetch detailed rent data for specific counties or metro areas, or retrieve entire statewide datasets for comparative analysis.
- Income Limits (IL) — Access median income data and limits for very low, extremely low, and low-income families by entity ID.
- MTSP Data — Retrieve Multifamily Tax Subsidy Project income limits for specific housing projects.
- Historical Analysis — Query data for specific years to track housing market trends.

Why Cursor?
Cursor's Agent mode turns HUD Fair Market Rents into an in-editor superpower. Ask Cursor to generate code using live data from HUD Fair Market Rents and it fetches, processes, and writes. all in a single agentic loop. 8 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

Frequently asked questions
How do I find the specific ID for a county to get its rent data?
First, use the list_states tool to get the state code, then use list_counties with that code. This will provide you with the 10-digit FIPS code (entity ID) needed for the get_fmr_data tool.
Can I retrieve rent data for an entire state at once?
Yes! Use the get_state_fmr_data tool and provide the two-letter state code (e.g., 'NY' for New York). It will return FMR data for all metro areas and counties within that state.
What is the difference between IL and MTSP data?
IL data (get_il_data) refers to general Income Limits for housing assistance, while MTSP data (get_mtsp_il_data) specifically targets Multifamily Tax Subsidy Projects. Both can be queried using the same entity IDs.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
