Colorado Code MCP server

Colorado Code — Colorado Revised Statutes by citation, topic, and title

Keyless. "C.R.S. 18-3-102" returns murder in the first degree.

Part of Pipeworx — an MCP gateway connecting AI agents to 1704+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

The official site redirects into a wall; a second official route does not

leg.colorado.gov's "C.R.S. Online" link does not host the text itself — it redirects into advance.lexis.com, a JS-rendered, cookie-session SPA whose own next step is a login-capture redirect (CaptureReturnUrl). That is the same class of wall this pack family declines (ASP.NET postback / anti-bot), and it has no stable per-citation URL to probe anyway.

The Office of Legislative Legal Services separately publishes the whole C.R.S. as downloadable files, one per title, on its own plain file server — no login, no JS, keyless:

https://olls.info/crs/crs2026-title-18.htm         (current edition)
https://olls.info/crs-archive/CRS-2015-TITLE-18.htm (a historical edition)

Files are per title, citations are per section — and titles are BIG

A title file holds the whole title plus case-law annotations after every section (Title 18 alone is ~9.5MB), so the section is cut out of it bounded by the next section heading OR the start of the annotations, whichever comes first. Annotations are Lexis's editorial case-law commentary, not the statute, and are never returned — only the statutory text, the Source: amendment history, and Cross references: (all public law).

The cut runs on the raw HTML, not the tag-stripped text, on purpose: a real section heading is the only place a citation is wrapped in NUM.. The per-article mini table-of-contents that precedes every article, and plain cross-references inside OTHER sections' annotations (a citation that happens to land at the start of a text line once tags are stripped), both repeat the same number unbolded — textually indistinguishable from a heading after stripping, never bold in the source.

Three file formats across 27 years of archive

Checked against Title 18 (old enough to exist in every edition):

2025 is declined explicitly (editionformatunsupported) rather than risk a silently wrong parse for one edition out of twenty-seven — almost certainly a one-year migration artifact between the other two generators. If a future year changes format again, costatute will start answering sectionnot_found for a title that exists; the same risk every sibling state pack already takes on the current year alone, just extended here across 25 archived years too.

Topic search is a nearby-heading window, not full hierarchy awareness

co_search runs against the ~18MB General Index (crs2026-index.htm), which is a nested tree — a topic heading followed by indented sub-entries that do not repeat the heading word. Matching only a result line misses that structure, so each query word is matched within a small window of the lines immediately preceding a citation-bearing entry. This works well for short topics (1-3 words: "landlord", "security deposit", "concealed handgun") and gets noisier on long compound phrases, which is why the tool description says so.
