Domain MCP servers
Specialized public intelligence. Turns a public dataset into a queryable, agent-ready domain expert.
Example · ADVmcp, 5500mcp
A Domain server turns a public dataset into something an agent can actually query.
The datasets are already public. Form ADV is on the SEC's site. Form 5500 is on the Department of Labor's. Anyone can download them. What nobody can do quickly is ask a question in plain language and get back the filed answer, with the filing date attached, without writing a scraper first.
That is the work: ingestion, normalization, a tool surface that maps to real questions rather than to database columns, and the discipline to report filed values exactly as filed. A Domain server that improves the numbers it returns has stopped being useful for the thing people use it for.
The role is distinct from Source because a Source hands back a provider's feed, while a Domain server has done editorial work on a public corpus. It is distinct from Composition because it answers within its own dataset and does not reach outward.
ADVmcp and 5500mcp are the Domain servers in this directory. Both are free and neither requires authentication.
