Overview

AI-generated overview

A remote MCP endpoint that gives an assistant verified reference facts such as rates, exams, recalls, holidays, and recent changes.

What it does
Databutler is a hosted MCP server reached over streamable HTTP at a fixed remote endpoint. According to its registry description, it supplies verified facts for AI agents covering rates, exams, recalls, holidays, and what has changed since a model's knowledge cutoff. No individual tools are listed in the supplied manifest, so the exact operations are not documented here.
When to use it
Consider it when an assistant needs current, checkable reference facts rather than general knowledge, for example interest or exchange rates, exam information, product recalls, or public holidays. It may also help when answers must account for events after a model's training cutoff.
Requirements
A remote MCP client that supports streamable HTTP, plus network access to the provider's endpoint. The manifest declares no authentication, no environment variables, and no headers, and no local package or runtime is needed.
Before you install
The manifest declares no authentication, so requests are not tied to a verified account; avoid sending sensitive or personal data through the endpoint. The server is third-party hosted, so queries leave your machine. No tools are listed, so verify what it can read or change before relying on it.
