What the publisher says

From the RuleStack MCP repository's README, as published. We do not edit it. Read it on GitHub

OpenLookup

MCP server from Compound Labs. Eleven read-only lookup tools backed by live public data — no API key, no signup, nothing to sign up for.

mcp-name: tech.thecompound/openlookup

OpenLookup was published on npm as compound-mcp until 2026-10-02. That package is deprecated and points here. Install openlookup instead.

Most OpenLookup tools answer questions that a model cannot answer correctly from its training cutoff. The underlying facts change after training, including current model costs, library maintenance, and whether someone has published a skill you plan to write.

Compliance

lookupadareport(domain)

OpenLookup looks up a US local-government domain in the [CivicBinder Municipal Web Accessibility Index](https://civicbinder.org/ada). The index uses axe-core scans of local-government .gov websites and grades them A–F against WCAG 2.1 AA. The index applies the April 26, 2027 ADA Title II deadline to communities of 50,000+ and the April 26, 2028 deadline to smaller communities and special districts.

The tool returns the grade, violation counts (total / serious / critical), the top failing rules, the entity's deadline, and the public report page (https://civicbinder.org/ada/). The full index is also published as an open dataset at [civicbinder.org/ada/dataset.json](https://civicbinder.org/ada/dataset.json).
