Compare SEC EDGAR MCP servers by verified scope

Capabilities are not interchangeable

Reviewed 2026-11-14. This is a scope comparison, not a ranking. We do not repeat provider archive-size, accuracy or speed claims as independently verified facts. Check current account terms and licensing on the provider’s own site.

Pick according to the output you need

For a question about the wording of a risk-factor section, begin with a connector documenting report or section retrieval. For a structured financial value, require a tool returning unit, period and accession context. For the stream of incoming event posts, a stream-oriented connector and delivery API may fit.

The SEC’s own free JSON and document access remain the source baseline. A third-party MCP wrapper may reduce integration work, but the protocol itself does not guarantee complete history, correct parsing or an accurate model answer.

Run the same acceptance case on each candidate

• Resolve one known company and retain its CIK.
• Retrieve a known accession and the relevant report or exhibit.
• Ask for one exact passage and verify it against the original document.
• Ask for one financial observation with unit, period and accession.
• Try a missing filing and confirm the server returns an explicit error or absence.
• Check pagination, amendments, oldest available history and account limits.
• Record the date, tool arguments and raw response before scoring the answer.

Avoid an unsupported winner

We have not run those acceptance cases against every listed connector. A vendor feature page establishes what the vendor documents, not what our account reproduced. Until the cases are executed, use the table to shortlist rather than to infer a quality or cost winner.

Synoptic owns this publication. Its MCP connector is presented with the same boundary: public metadata operations were verified, while authenticated filing-post reading and source-document analysis were not.
