Indiana Code MCP

Public home: Open Indiana Law (open-indiana-law/indiana-code). Preferred site will be openindianalaw.org (not live yet). Live unofficial MCP: mcp.indianacle.com. This copy is unofficial and is not legal advice.

Dated, unofficial copies of the Indiana Code (2017–2026) as a local MCP server. Search, citation resolve, as-of text, version history, outline browse, and public-law clause lookup.

This is an access layer, not an official publication, and not legal advice. Verify every citation at iga.in.gov.

The older IGA-API / opinions server in src/mcp_server.py is historical and is not wired to any database. Use python -m indiana_law.mcp_server.

Tools

Every answer includes unofficial, snapshot, dates, flags, and a disclaimer.

Setup

python3 -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"

# Point at a built store (this checkout already has one):
export INDIANA_LAW_DB="$PWD/data/store/indiana-code.db"

Rebuild from the official JSONL already on disk: docs/REBUILD.md. Coverage limits: NOT_COVERED.md.

python -m pytest tests
INDIANA_LAW_DB=data/store/indiana-code.db python scripts/smoke_mcp.py

Run the MCP server (stdio)

export INDIANA_LAW_DB=/absolute/path/to/indiana-code.db
python -m indiana_law.mcp_server

Cursor

Add to ~/.cursor/mcp.json (or the project MCP config):

{
  "mcpServers": {
    "indiana-code": {
      "command": "python",
      "args": ["-m", "indiana_law.mcp_server"],
      "env": {
        "INDIANA_LAW_DB": "/absolute/path/to/indiana-code.db",
        "PYTHONPATH": "/absolute/path/to/indiana-law/src"
      }
    }
  }
}

If you installed the package into a venv, use that venv's python and you can drop PYTHONPATH.

Hosted prototype

A hosted, unofficial instance of this server runs at https://mcp.indianacle.com (Streamable HTTP endpoint https://mcp.indianacle.com/mcp, with a landing page at the root and the terms at /terms). It is an early prototype with known gaps; see NOT_COVERED.md and the terms page, and verify every citation at iga.in.gov. It is not legal advice. Opening /mcp in a browser shows a JSON 406 error: that is the machine protocol, not a broken site. For how it is hosted, see docs/DEPLOY.md.
