What will the city and utility charge me to build here?
muni-dev-cost is an MCP server (and a pay-per-call x402 API) that gives an AI
agent the municipal development cost for a US jurisdiction β the
impact/development fees, water & sewer tap (connection) fees and
capital-recovery charges a real-estate developer must pay before breaking
ground β aggregated and normalized from public, government-published fee
schedules into one comparable number.
For a real-estate development-feasibility / pro-forma agent, this number is load-bearing and, today, costs weeks of manual digging across municipal ordinances, utility fee schedules and county portals. We do the aggregation so your agent doesn't have to.
// add to your MCP client config
{ "mcpServers": { "muni-dev-cost": { "command": "npx", "args": ["-y", "muni-dev-cost-mcp"] } } }
Tools
1 free + 13 premium tools. The free
get_dev_costsis the hook; the 13 premium tools are the depth a feasibility agent can't assemble itself.

{ "jurisdiction": "Phoenix, AZ" }
ποΈ Phoenix, AZ Β· coverage π’ deep
Municipal development cost, single-family home: $29,322
β’ Water + sewer (impact + tap): $29,322
Fees included (one line each):
β’ Wastewater Collection impact fee: $5,127 (per dwelling)
β’ Wastewater Treatment impact fee: $3,753 (per dwelling)
β’ Water Transmission impact fee: $14,046 (per dwelling)
β’ Water Treatment impact fee: $4,387 (per dwelling)
β’ Water Resource Acquisition fee: $2,009 (per dwelling)
Coverage (honest β regla 7)
We never pass off an estimate as a city's published number.
- π’ deep β the city's own water/sewer fee schedule was ingested, including
the per-meter table. Figures are
published. - π‘ partial β headline impact figures from public schedules; some categories estimated.
- π estimated β the exact city isn't in our deep KB yet, so figures are a regional benchmark, clearly marked. Use as order-of-magnitude only.
Coverage today: 130 jurisdictions across 38 states β 109 deep (own per-meter/per-LUE schedule ingested) + 21 partial. Dense in the high-growth markets a feasibility agent actually screens: TX (18), CO (18), FL (18), NC (16), CA (11), plus AZ, GA, WA, OR and more. From the cheapest covered market (Mobile, AL ~$1,000) to the priciest (Erie, CO ~$78,350), ranked and queryable. Any US city not yet ingested returns an honest state benchmark estimate β and the deep KB grows every iteration.
All fee data is sourced from public, government-published fee schedules (works of US municipal government β public domain). Each jurisdiction carries its source URL and effective date. Indicative β verify the exact amount with the jurisdiction. Not legal or fee-certification advice.
Two ways to pay for the premium tools
- π³ Card (Stripe) β buy a prepaid API key at
/pro/checkout, then set"env": { "MUNI_DEV_COST_KEY": "<key>" }. - πͺ x402 (USDC on Base) β AI agents pay per call automatically; no signup.
The free get_dev_costs works with no key.
How it stays a moat
The aggregation engine, the normalized fee knowledge base and the accumulating
per-jurisdiction cache run server-side. The npm package is a thin client:
it forwards your call to the hosted server and renders the response. The fee data
and the premium logic never ship in the tarball β a moat verified on every build
by npm run test:moat.
