MCP

SEC data your AI agents can trust

The 3spread MCP server puts our standardized, source-traceable filings one tool call away, so assistants and agents answer from the filing itself instead of guessing.

Ground agent workloads in verified data

Every tool call returns the filer's own reported figures, standardized and traceable back to the source. Your agents work from verified numbers instead of inventing them.

  • Every value traces back to the filing it came from
  • Reconciled to the filer's own reported totals before it is served
  • Point in time, so answers do not silently change under a restatement
  • Zero generative AI in the data itself

Agentic access to best-in-class fundamental data

One connection exposes the full 3spread catalog as tools: fundamentals, ownership, fund holdings, and the filings behind them. Agents discover what they need and fetch it, with no glue code in between.

  • Search and fetch across every filing family
  • One standardized schema, so results join cleanly
  • The same data the REST API serves, with no separate pipeline

What agents do with it

Investment research

Ask for a filer's fundamentals or insider activity and get an answer grounded in the filing, not a guess.

Screening and monitoring

Point an agent at the whole universe to flag new filings, insider trades, and ownership changes as they land.

Due diligence

Pull the exact figures and sections behind a name, with the provenance attached to every number.

Analysis and modeling

Feed standardized, point-in-time data into an agent that builds a model or checks one against the source.
