Use Synoptic MCP for SEC stream research

Inspect the canonical SEC stream first

Search the catalog for SEC and inspect stream 01JSPH2HZMMND30770DECW091Q. Our public probe returned SEC Edgar Filings | GOV Releases with an ACTIVE state and API access enabled. It also found delayed and non-API variants, making the exact ID important.

The catalog description labels this stream NO DELAY. No independent delivery timing was measured. The package-only wording conflicts with one structured flag, so check current entitlement inside the product before planning access.

Use the actual tool arguments

Three tool-call argument objects, not a JSON-RPC envelope. Only the first public metadata lookup succeeded in the anonymous publication test; the two authenticated examples were not run.

Keep pagination and evidence explicit

The live tool schema lists nextToken for get_stream_posts history and nextOffset for search_stream_posts text results. Reuse the history token with unchanged date bounds, and use the text-search offset according to its own result. Do not assume the two pagination systems are interchangeable.

Return the post ID, stream ID, createdAt and source metadata when present. Follow the original source link to verify any substantive filing claim. A post mentioning a quarterly filing does not establish a parsed XBRL observation or a complete copy of its exhibits.

Use another interface for continuous monitoring

A stored-post MCP call reads existing content. If the requirement is continuous delivery, use a separate reader on the documented WebSocket API with persistence, reconnect handling and a recovery plan. The assistant conversation alone is not a long-running monitor.

Start with the public connection check, then authenticate only for the required reading task. If you need the wording of an entire 10-K or a structured financial table, use official SEC data or a filing-focused connector that documents and passes that acceptance case.
