All limitations / Review context
Do extracted figures retain source provenance and uncertainty labels as filing schemas change?
The bounded review of the publisher's documented Signal8 SEC filing extractions and dilution-intelligence tools and release notices identified no disclosed material condition preventing an accurately scoped public tracking entry. The resource's operational permissions remain uncertainty; this assessment does not certify installation safety.
- Read-oriented research integration; outputs should not be treated as investment guarantees.
- Primarily read/search/analysis against financial/SEC data.
- Signal8 API key.
- Queries/results transit Signal8 APIs and hosted filing/derived-intelligence stores.
- Sensitive access: Financial/SEC/company intelligence, API key
- Installation, client compatibility and comprehensive security have not been independently audited. Authentication and access depend on the configured services.
- Runtime behavior, dependencies and undisclosed vulnerabilities were not independently audited.
- Documented tool authority and any remote data handling must be checked before installation or use.
- Tool inventory, client matrix and permissions completeness were not requirements for this Radar tracking review.
- Requires Signal8 API key/credits.
- Archive coverage before October 2021 can be incomplete.
- Some extracted tools are intentionally disabled/not registered.
- Tool availability should be treated as live.

Suggested checkUser-side suggested check (not executed): inspect registered tools/connection and perform publisher-supported read-only status/list operations. Do not send, purchase, publish, delete, sign, trade or alter data as a smoke test.
Remove / uninstall / revoke
MCP100 setup guideGeneric client guidance (not publisher-specific uninstall): unregister MCP entry in the chosen client. If installed globally, remove the npm package separately. Revoke provider access separately through account controls, where supported. This does not erase local data or revoke funds/credentials automatically.
Unregister the named MCP entry from the actual host separately from removing a global npm install; no claim that either revokes remote credentials.
Remove local stored keys/tokens and revoke or rotate corresponding provider authorization using documented provider account controls if available; exact procedure not verified for this package. Wallet private keys cannot be revoked.
