How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Supply Chain Security32
Provenance & Transparency45
Schema Quality & AI Usability68
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 2408 tokens (~218/item across 11 items; 11 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 11 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Install

How do I install the io.github.matematicsolutions/us-eli-mcp server?

io.github.matematicsolutions/us-eli-mcp runs locally as a PyPI package, launched with uvx us-eli-mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 11 exposed · ~1,155 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
us_coverage ~102

Declare what this connector covers, how it is sourced, and what it does NOT cover. Call this before telling a user that the law "does not contain" something, and whenever a search comes back empty: the absence may be a gap in this connector rather than in the law. Every gap carries a fallback saying where to look instead. Returns: ``Coverage`` with families, an as-of note, and a non-empty list of known gaps.

Input schema present but exposes no named parameters.

NameTypeReqDescription
as_of_notestringyesStates what the dates mean, and what they do not promise.
familiesarray
known_gapsarrayNever empty. An empty list would mean 'not checked', not 'no gaps'.

us_get_federal_register_doc ~57

Fetch full metadata for one Federal Register document.

us_search_bills ~119

List US federal bills of a given congress and bill type.

NameTypeReqDescription

Common questions

What is the io.github.matematicsolutions/us-eli-mcp server?

io.github.matematicsolutions/us-eli-mcp is listed in the public MCP registry as io.github.matematicsolutions/us-eli-mcp. US law MCP: bills, US Code, Federal Register, executive orders, case law (state+federal), eCFR. This page covers its PyPI package (us-eli-mcp).

Is the io.github.matematicsolutions/us-eli-mcp server safe to use?

io.github.matematicsolutions/us-eli-mcp scores 63 out of 100 on VerifyMCP. We recorded 2 known advisories against it as of 20 September 2026. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the io.github.matematicsolutions/us-eli-mcp server expose?

io.github.matematicsolutions/us-eli-mcp exposes 11 tools: us_search_bills, us_get_bill, us_list_code_packages, us_get_code_package, us_search_federal_register, and 6 more. Their descriptions and schemas cost roughly 1,155 tokens of context every time the server is loaded.

Is the io.github.matematicsolutions/us-eli-mcp server still maintained?

io.github.matematicsolutions/us-eli-mcp is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the io.github.matematicsolutions/us-eli-mcp server under?

io.github.matematicsolutions/us-eli-mcp declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
