Overview

AI-generated overview

Remote MCP server that returns aggregated US municipal development impact and water/sewer tap fees for a jurisdiction, with premium fee-breakdown and comparison

What you can do
Look up the aggregated municipal development cost for a US jurisdiction, split into water and sewer versus other impact fees, with a coverage label (free tool). Get line-by-line fee breakdowns by category, per-meter-size water and sewer schedules, and source documents with effective dates. Estimate whole-project or per-unit fees for single-family, multifamily and mixed development. Compare and rank jurisdictions by cost, roll up costs by state, and review dated fee revision history and trends.
When to use it
Useful for real-estate feasibility, pro-forma and site-selection work where an assistant needs an order-of-magnitude municipal impact and utility connection cost for a US city without digging through ordinances and utility schedules. Best for screening high-growth markets; treat results as indicative and verify with the jurisdiction.
Requirements
A remote streamable HTTP endpoint; no local runtime or package needed. The free cost lookup works without a key. Premium tools need a prepaid API key from the provider's card checkout, supplied as the MUNI_DEV_COST_KEY environment variable, or per-call payment via x402 in USDC on Base. Network access required.
Before you install
Premium tools are paid: either a prepaid key purchase or per-call USDC payments, so an agent could spend money automatically. Figures are aggregated and sometimes estimated from regional benchmarks rather than a city's published schedule; the provider states they are indicative and must be verified with the jurisdiction, and are not legal or fee-certification advice. Queries are forwarded to the hosted server.

Installation

In SourceWeft

  1. Open Muni Dev Cost in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

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/io.github.Baneado98%2Fmuni-dev-cost/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.

Read the install guide the agent follows

README

muni-dev-cost 🏗️

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 — the impact/development fees, water & sewer tap (connection) fees and capital-recovery charges a real-estate developer must pay before breaking ground — 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.

Tools

ToolTierWhat you get
get_dev_costsFreeThe aggregated municipal development cost for a jurisdiction (single-family home), split into water+sewer vs other impact, with a per-fee summary and an honest coverage label.
get_fee_breakdownPremiumEvery fee line by line, grouped (Water / Sewer / Transportation / Parks / Drainage), with the per-meter-size schedule and each source + effective date.
compare_jurisdictionsPremiumRank 2–12 markets side by side for site selection — total, water+sewer split, the dollar/% spread and what it costs on a 100-unit project.
get_water_sewer_detailPremiumWater & sewer connection cost by meter size (5/8" → 12") — the single biggest swing in a utility connection budget.
estimate_dev_costPremiumWhole-project fees (fees × units) with per-unit and extended line items, dev-type aware, explicit about exclusions.
list_jurisdictionsPremiumThe full coverage map — every jurisdiction, its depth and data freshness, which publish a per-meter schedule, plus the benchmark states.
get_fee_schedule_sourcePremiumThe published source document + per-fee provenance (published vs estimated) behind a jurisdiction's number — defensible trazabilidad for a pro-forma.
get_cost_trendPremiumThe real dated revision history of a jurisdiction's headline fee (prior years + adopted future steps) with YoY delta and CAGR — never a projection.
compare_by_meter_sizePremiumOne jurisdiction's water/sewer cost across every published meter size, ratioed to the 5/8" residential base.
estimate_by_unitsPremiumMultifamily/mixed fee estimate by LUE (units × LUE-per-unit) — the way cities actually bill MF, so it doesn't overstate fees.
get_total_dev_costPremiumThe grand total across every fee category (water/sewer, transportation, parks, drainage, public-safety, other), bucketed — with honest $0 buckets where a city simply doesn't charge that category.
breakdown_by_fee_categoryPremiumEvery line item within one category (e.g. all of a city's parks fees) with per-meter detail — errors honestly if the city doesn't levy that category.
rank_jurisdictions_by_costPremiumRank the entire covered KB cheapest→priciest by water+sewer or total, with cheapest/median/priciest, the spread, and a site-selection insight — filterable by state/coverage.
summarize_by_statePremiumA state-level roll-up over the whole KB: per state, the city count, min/median/max cost, cheapest/priciest city, and which fee categories are assessed — the map for "which states are cheap/expensive to build in."

1 free + 13 premium tools. The free get_dev_costs is the hook; the 13 premium tools are the depth a feasibility agent can't assemble itself.

Example (free)

POST https://muni-dev-cost-mcp.vercel.app/dev-costs{ "jurisdiction": "Phoenix, AZ" }
🏗️  Phoenix, AZ  ·  coverage 🟢 deep   Municipal development cost, single-family home: $29,322     • Water + sewer (impact + tap): $29,322   Fees included (one line each):     • Wastewater Collection impact fee: $5,127  (per dwelling)     • Wastewater Treatment impact fee: $3,753  (per dwelling)     • Water Transmission impact fee: $14,046  (per dwelling)     • Water Treatment impact fee: $4,387  (per dwelling)     • Water Resource Acquisition fee: $2,009  (per dwelling)

Coverage (honest — regla 7)

We never pass off an estimate as a city's published number.

  • 🟢 deep — the city's own water/sewer fee schedule was ingested, including the per-meter table. Figures are published.
  • 🟡 partial — headline impact figures from public schedules; some categories estimated.
  • 🟠 estimated — 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 — 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 — and the deep KB grows every iteration.

All fee data is sourced from public, government-published fee schedules (works of US municipal government → public domain). Each jurisdiction carries its source URL and effective date. Indicative — verify the exact amount with the jurisdiction. Not legal or fee-certification advice.

Two ways to pay for the premium tools

  • 💳 Card (Stripe) — buy a prepaid API key at /pro/checkout, then set "env": { "MUNI_DEV_COST_KEY": "<key>" }.
  • 🪙 x402 (USDC on Base) — 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 — a moat verified on every build by npm run test:moat.
