Sizing Sheet MCP server

Which MCP servers are Sizing Sheet's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry nameloan.fhamultifamily/fhamultifamily-loanverified in the MCP registry

The registry name sits under fhamultifamily.loan. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: estimate the maximum FHA-insured loan for a property; compare which FHA multifamily program fits a deal; check the per-unit statutory loan limit for a property.
  • Checked on 4 of the 7 days it takes to judge reliability.

Once connected

  • For "estimate the maximum FHA-insured loan for a property", the likely first call is size_loan.
  • For "compare which FHA multifamily program fits a deal", the likely first call is choose_program.
  • For "check the per-unit statutory loan limit for a property", the likely first call is get_limits_and_costs.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • choose_program

    Runs the three-question FHA multifamily program chooser from fhamultifamily.loan/chooser: returns the likely program (223(f), 221(d)(4) new construction or substantial rehab, 223(a)(7), 241(a), or "not FHA yet"), the reason, and the…

  • size_loan

    Estimates the maximum FHA 223(f) or 221(d)(4) loan the way HUD Form 92264-A does, with the fhamultifamily.loan sizer: statutory limit (2026 per-unit limits x high-cost %), loan to value or cost, debt service coverage with 0.25% MIP, the…

  • get_limits_and_costs

    HUD's 2026 FHA multifamily rulebook as the site publishes it: per-unit statutory limits by bedroom (Section 207/223(f)/220, 221(d)(4) or 231; elevator and non-elevator) with the high-cost amount for a state, loan-to-value and coverage…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "fhamultifamily-loan": {
      "type": "http",
      "url": "https://fhamultifamily.loan/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http fhamultifamily https://fhamultifamily.loan/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://fhamultifamily.loan/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
