Dartmouth Advisory Partners
A free regulatory change feed for financial regulators in Canada, the United States, the United Kingdom and the European Union, delivered as an MCP connector. No account, no key, no seat licence.
Bellwether collects what financial regulators publish, normalises it into one record shape, and serves it to any MCP client as a set of read-only tools. It holds prior state, so it can tell you that a document was amended after publication and what the earlier text said. That is the difference between detecting change and displaying a list.
It is built for the people who have to keep track: compliance and legal teams, risk and policy functions, analysts covering regulated sectors, and anyone who would otherwise be checking 10 regulator pages by hand.
Coverage begins from when the service first collected each source. It is not a complete historical archive, and the tools say so rather than letting an absence of results look like an absence of regulation.

There is nothing to authenticate and nothing to configure. Adding a connector does not switch it on by itself, so the last step matters. Free plan users are limited to one custom connector. On Team and Enterprise plans an owner adds it for the organization first.
| search_regulatory_changes | What a regulator has published on a topic, or in a window |
| recent_regulatory_changes | What is new across all regulators |
| get_regulatory_change | A full record, plus every revision observed since first collection |
| list_coverage | What is monitored, and how fresh each source is |
All four are read-only. There is no write surface.
10 feeds across 4 jurisdictions. This list is generated from the live source registry, so it is what the connector actually collects rather than what it once intended to.
Not monitored: CIRO (Canada), TPR (United Kingdom), EIOPA (European Union). These are listed rather than quietly omitted, because an absence of results is only meaningful if you know what is being watched.
Bellwether went from a question to a deployed public service in under forty minutes, built by one person who does not write code, working with Claude.
It runs on Cloudflare Workers with a D1 database and a cron trigger every six hours. The ingest normalises 10 feeds into one record shape and hashes each record, so an amendment is detected rather than quietly overwritten. The MCP layer is written against the streamable HTTP transport. There is a test suite, a privacy statement, a custom domain, and an entry in the official MCP Registry under a DNS verified namespace. Hosting costs nothing at this volume.
The source is public under the MIT licence. Read it, fork it, run your own.
The point is not that the tool is clever. It is that the cost of building a working, governed, production system has collapsed, and most of what institutions license today was priced before that happened.
Dartmouth Advisory Partners is software in a service, not software as a service. We do not hand you a licence and wish you luck. You name the outcome. We build the system that produces it, in your environment, and you own what we build.
We work with compliance, risk and investment functions at asset owners, asset managers, OCIOs, pensions, insurers and family offices. Work that is quoted in quarters elsewhere gets delivered here in weeks, and often in days. This page is the evidence, not the exception.
If something here made you think of a problem in your own shop, that is the conversation.
The connector collects no personal data. This page counts visits without cookies or identifiers.
