README

us-eli-mcp

MCP server for US law with verifiable citations. Five sources behind ten read-only tools:

Congress.gov API - the federal legislative process: bills as they move through committees and floor votes.
GovInfo API - enacted law text as published packages: US Code, Statutes at Large, CFR annual editions, Federal Register issues.
Federal Register API - full-text search over 1,003,504 FR documents (1994-2026, live-verified 2026-07-07), including 8,513 presidential documents (1,550 executive orders). Keyless.
CourtListener search API - full-text search over 8,294,123 court opinions (live-verified 2026-07-07). The headline value is STATE case law (California, New York, Texas, ...), which no federal source covers. Keyless, ~5 requests/min anonymous.
eCFR API - the CURRENT Code of Federal Regulations: section-level full-text search over 412,846 sections plus per-section amendment history. Keyless.

What this is not

State legislation (all 50 states) - see LegiScan, a free-tier aggregator (30,000 queries/month) not wrapped here.
A federal case-law workhorse - for heavy federal case-law research the mature MIT-licensed wrappers (blakeox/courtlistener-mcp, john-walkoe/courtlistener_citations_mcp) remain the recommendation; the case-law tools here exist primarily for state courts. See SOURCES.md.

Tools

Tool	Purpose
`us_search_bills`	List bills by congress (e.g. `118`) and type (`hr`, `s`, `hres`, ...)
`us_get_bill`	Full detail + latest action for one bill
`us_list_code_packages`	List GovInfo packages in a collection (`USCODE`, `CFR`, `FR`, `STATUTE`)
`us_get_code_package`	Metadata + download links (PDF/XML/TXT) for one package
`us_search_federal_register`	Full-text search over FR documents; filter rules, notices, executive orders
`us_get_federal_register_doc`	One FR document with its official citation (e.g. `91 FR 41591`)
`us_search_case_law`	Full-text search over 8M+ opinions; `court` filter (e.g. `cal`, `ny`, `scotus`)
`us_get_case`	One opinion cluster by `cluster_id`
`us_search_cfr_sections`	Full-text search over the current CFR (eCFR)
`us_get_cfr_section_history`	Amendment history of one CFR section (e.g. 15 CFR 744.3)

Every response carries lex_uri (a resolvable API URL), human_readable_citation (the official convention: "H.R. 1, 118th Congress", "91 FR 41591", "People v. Miranda-Guerrero, 519 P.3d 1004 (California Supreme Court 2022)", "15 CFR § 744.3") and source_url (the public page). Reporter citations are taken verbatim from the source and never fabricated; when none exists the docket number is used instead.

Install

pip install us-eli-mcp

Configuration

Env var	Default
`US_ELI_API_KEY`	`DEMO_KEY` (shared, low rate limit - get your own free key at api.congress.gov/sign-up)
`US_ELI_GOVINFO_API_KEY`	reuses `US_ELI_API_KEY` (same api.data.gov key family)
`US_ELI_CACHE_DIR`	`~/.matematic/cache/us-eli`
`US_ELI_AUDIT_DIR`	`~/.matematic/audit`
`US_ELI_BASE_URL`	`https://api.congress.gov/v3`
`US_ELI_GOVINFO_BASE_URL`	`https://api.govinfo.gov`
`US_ELI_FR_BASE_URL`	`https://www.federalregister.gov/api/v1` (keyless)
`US_ELI_COURTLISTENER_BASE_URL`	`https://www.courtlistener.com/api/rest/v4` (keyless)
`US_ELI_ECFR_BASE_URL`	`https://www.ecfr.gov/api` (keyless)

The Federal Register, CourtListener and eCFR tools need no key at all.
