README

1acre MCP

The official MCP (Model Context Protocol) server for 1acre.in — India's verified land marketplace. Connect Claude Code, Cursor, Claude Desktop, or any MCP-compatible client to look up survey numbers, browse cadastral data, and generate land-intelligence reports on behalf of your 1acre account.

This repository contains the client-side configuration and documentation — how to connect. The server itself runs at https://mcp.1acre.in.

What you can do

Once connected, any MCP client can call these tools as the signed-in 1acre user:

ToolCostDescription
get_token_balanceFreeCheck your token balance, tier allowance, and what each paid tool costs
browse_locationsFreeWalk the location hierarchy (state → district → mandal → village)
list_survey_numbersFreeList survey numbers that exist in a given village
list_available_layersFreeDiscover which map layers (Master Plan, air-funnels, expressways, metro, etc.) cover a lat/lng — metadata only
get_survey_number_reportFreeRe-open a previously generated report by ID — no tokens spent
get_report_coordinatesFreeGet GeoJSON boundary coordinates for a previously generated report
create_sell_listing_intentFreeCapture a "sell my land" intake — returns a pre-filled WhatsApp link to the 1acre listings team
get_layer_info5 tokens per layerFetch feature attributes at a lat/lng inside a paid map layer (zone, permissible height, corridor distance). Misses are free.
list_lands_in_region1 token per pageUp to 10 verified 1acre land listings within a radius of a lat/lng (per page). Empty pages are free.
create_survey_number_report10 tokensGenerate a full land-intelligence report for a specific survey number
identify_parcel_at_point10 tokensIdentify the cadastral parcel at a lat/lng coordinate and generate its report

Paid tools spend from your "1a" token balance. Free tools cost nothing — once a report exists, you can re-open it and pull its boundary coordinates as often as you like without spending another token.

Call get_token_balance first (it's free) to see your live balance and the current per-tool price. A run that would overdraw fails with insufficient_tokens and is recoverable — top up from the My Tokens page on 1acre and retry.

"Tokens" here means 1acre land-intelligence credits — unrelated to the OAuth access tokens your MCP client manages for sign-in.

Quick start — Claude Code

bash
claude mcp add --scope user --transport http 1acre https://mcp.1acre.in/mcp \  --callback-port 8118 \  --client-id eKg8BebDnd09zxwy

Then in Claude Code:

  1. Type /mcp — you'll see 1acre with Needs authentication
  2. Click Sign In
  3. Browser opens 1acre's sign-in page (phone number)
  4. Enter your phone number → receive OTP via SMS → enter code
  5. Consent screen → Allow
  6. 1acre flips to ✓ Connected

Now ask Claude anything land-related: "How many 1acre tokens do I have left?", "What districts does Telangana have?", etc.

Quick start — Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or the equivalent path on your OS:

json
{  "mcpServers": {    "1acre": {      "url": "https://mcp.1acre.in/mcp",      "transport": "http",      "oauth": {        "clientId": "eKg8BebDnd09zxwy",        "callbackPort": 8118      }    }  }}

Restart Claude Desktop. Sign in via the MCP servers dialog.

Quick start — Cursor

Cursor's MCP config lives at ~/.cursor/mcp.json. Add:

json
{  "mcpServers": {    "1acre": {      "url": "https://mcp.1acre.in/mcp"    }  }}

Cursor prompts you to authenticate on first tool call.

Authentication

1acre MCP uses OAuth 2.1 with PKCE. Sign-in is phone-number-based via one-time SMS verification (secure, DLT-compliant for Indian phone numbers).

  • Your phone number becomes your identity.
  • You must have a 1acre.in account first — sign up at 1acre.in with the phone number you plan to use. MCP resolves your Clerk identity to that Account by matching the phone.
  • Sessions are managed by the auth server; your MCP client refreshes tokens automatically.

Registering an OAuth client

Most clients register automatically. 1acre's OAuth provider supports RFC 7591 Dynamic Client Registration at https://clerk.1acre.in/oauth/register — MCP clients that speak DCR (Claude Code, Smithery, and others) discover this from .well-known/oauth-authorization-server and register themselves on first connect. You don't need to do anything, and the --client-id flag in the Quick Start above is only needed if your client can't do DCR.

Manual registration (only if your client doesn't support DCR)

Contact [email protected] with:

  1. Your MCP client name (e.g. "Internal agent X")
  2. The exact callback URL your client will use

You'll receive a client_id (public — safe to commit; PKCE-only, no client secret).

Available at

  • MCP endpoint: https://mcp.1acre.in/mcp
  • Discovery: https://mcp.1acre.in/.well-known/oauth-protected-resource
  • Health: https://mcp.1acre.in/healthz

Costs & limits

  • Free tools (balance check, discovery, hierarchy browse, list survey numbers, sell-listing intent, re-read reports, get coordinates): unlimited
  • Paid tools:
    • get_layer_info — 5 tokens per layer that returns a feature (misses are free)
    • list_lands_in_region — 1 token per non-empty page (10 listings per page; empty pages are free)
    • create_survey_number_report — 10 tokens per report
    • identify_parcel_at_point — 10 tokens per run
  • Rate limits: 60 requests/minute per OAuth access token

Token allowance by account tier:

TierAllowance
Non-premium (regular, free trial, expired premium)100 tokens
Premium — quarterly plan500 tokens
Premium — yearly plan2,000 tokens

Tokens expire 365 days after they are credited — this is a balance, not a lifetime allowance. Purchased top-up packs stack on top of your tier allowance, so a balance above the figures above is normal. get_token_balance is always the source of truth for what's actually spendable.

For higher limits, contact [email protected].
