Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (4)

`get_document_status`	Check the status of a document previously sent for signature: overall state (sent/completed/declined/expired/voided), per-recipient progress (pending/viewed/signed), and the signed PDF download URL once complete. Requires a SignSimple API key.
`list_documents`	List the 25 most recent documents sent from the connected SignSimple account, with status and signed-PDF URLs where complete. Requires a SignSimple API key.
`list_templates`	List SignSimple's free, professionally drafted document templates (NDA, lease, contractor agreement, liability waiver, bill of sale, promissory note). Returns each template's info page and direct PDF URL — pass the PDF URL to send_for_signature as document_url to send one. No API key needed.
`send_for_signature`	Send a PDF document for legally binding electronic signature via SignSimple (free, unlimited). Provide the PDF as a fetchable URL or base64, plus recipient name(s) and email(s). Each recipient is emailed a secure signing link; signature and date fields are placed automatically unless custom fields are given. Works with the free templates from list_templates (pass their pdf URL as document_url). Requires a SignSimple API key (create one at https://signsimple.app/profile).

Schemas: list_tools.
