Indiana Code MCP Server

Indiana Code

Indiana Code by citation, plus full-text topic search and historical (per-year) annual editions. Keyless.

Part of Pipeworx — an MCP gateway connecting AI agents to 1865+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Source (fleet #2724)

The Indiana General Assembly's code viewer (iga.in.gov) is a React SPA. Its own JS bundle names its data source directly (REACT_APP_API_URL), and the page a title renders fetches one plain document per title per year:

https://iga.in.gov/ic/<year>/Title_<N>.html

One document per TITLE, not per section — Title_9.html (Motor Vehicles) is ~5.9 MB and contains all of Title 9's ~2,300 sections for that year. <year> is the same field the SPA calls in_code_year — this is the historical- version capability: in_code_section's year argument fetches the exact same shape for a past year (e.g. 2018), rather than needing a separate archive API. Measured 2026-10-06: Title 9 has real content back to 2017; some titles' earliest year differs, so a request for a year with no archived content returns year_or_title_not_found rather than a hardcoded floor.

The upstream needs a browser-shaped User-Agent. A bare UA (including a plain "Mozilla/5.0") gets HTTP 200 with a 691-byte SPA shell — silent emptiness, not an error. Mozilla/5.0 (compatible; pipeworx-mcp-indiana-code/1.0; +https://pipeworx.io) — the same honest bot-UA convention this repo already uses elsewhere (19hz, fed-comms) — passes; no Referer, cookie, or JS challenge needed. Confirmed with a plain curl, outside any browser.

Citation lookup

in_code_section resolves a citation (e.g. "9-21-5-5", "32-31-3-6") by locating its boundary marker — a section-classed element keyed by the citation itself — in the title document. Every title/article/chapter/section in the source carries the same marker shape, so one boundary scan finds a section's exact start and end regardless of its depth in the hierarchy.

For the current code, it tries a pre-fetched bundle first (scripts/ingest-indiana-statutes.mjs, written to the shared pipeworx-datasets R2 bucket at statutes/in/<title>.json — one bundle per title, 37 total) and falls back to a live fetch if the bundle is missing. For an explicit year different from the bundle's own ingested year, it always goes live — the pre-fetched bundle only ever holds the current code; historical years are not pre-ingested because the live path is not throttled (unlike mcps/north-carolina-code's per-section path on ncleg.gov).

Each section's trailing "As added by..."/"Amended by..." note (and any "[Pre-<year> Recodification Citation: ...]" line) is split out into its own history field rather than left inside text — the amendment-history capability the task asked for, same split mcps/california-code makes for its own trailing enactment parenthetical.

Topic search

in_code_search answers questions no citation lookup can — "landlord retaliatory eviction", "oversized vehicle permit" — via FTS5 in the shared SEARCH_SHARD Durable Object (workers/gateway/src/search-shard.ts, shard name in-statutes; no new Cloudflare binding, per docs/gateway-text-binding-limit.md). Search hits carry a citation and heading; call in_code_section with the section from a result for the full text.

Coverage

All 37 Indiana Code titles that exist as separate documents (Title 7 is fully folded into 7.1 and returns no separate content; Titles 17/18/19 are "REPEALED" stubs with a marker and zero sections — both kept as real, zero-section results rather than treated as missing). 77,780 sections ingested across 37 titles for the 2026 code.

Refresh

node scripts/ingest-indiana-statutes.mjs — re-run periodically (the General Assembly convenes annually; there is no daily-freshness need). No schedule is wired up: dispatch by hand, following the same pattern as scripts/ingest-nc-statutes.mjs.

Data source

Official state legislature site (iga.in.gov). Indiana statutes are public record; no reuse restriction was found on the title bulk-document paths used here.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "indiana-code": {
      "url": "https://gateway.pipeworx.io/indiana-code/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/indiana-code/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1865+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/in_code_section \
  -H 'Content-Type: application/json' \
  -d '{"section":"9-21-5-5"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/in_code_section. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Run it from npm

@pipeworx/mcp-indiana-code is a local stdio bridge to the Pipeworx gateway: your MCP client starts it with npx, and it forwards every call to the same https://gateway.pipeworx.io/indiana-code/mcp endpoint shown above. It needs network access; there is no offline mode.

{
  "mcpServers": {
    "indiana-code": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-indiana-code"]
    }
  }
}

Without a key it calls anonymously, capped at 50 calls a day. A free account raises that to 200 a day: get a key at https://pipeworx.io/signup and add "env": { "PIPEWORX_API_KEY": "<your key>" } to the server entry. The key is sent as a Bearer token, the same way a hosted connection sends it, so calls are metered and billed exactly as they are there.

It lists only this pack's tools by default. Set PIPEWORX_META_TOOLS=1 to also list ask_pipeworx and the other gateway-wide tools.

Behind an HTTPS proxy: Node's built-in fetch does not read HTTPS_PROXY by default. Newer Node releases honour it when NODE_USE_ENV_PROXY=1 is set; check your Node version's documentation.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Indiana Code data" })

The gateway picks the right tool and fills the arguments automatically.
