SwiftSign MCP

Official MCP server for SwiftSign enabling AI agents to handle e-signatures. It supports minting sandbox keys, sending PDFs for signing, tracking envelope status, and downloading sealed results with integrity hashes. It provides both local npx installation and remote HTTP transport options for integration with AI coding tools.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

swiftsign_send_envelope
Advertised by the server during the last successful anonymous check.
Advertised destructiveOpen-world

Send a document for e-signature. Accepts PDF as base64, recipients, and field placement. Sandbox keys (sk_test_) send immediately (watermarked test mail). LIVE keys create a DRAFT and return it for human review unless confirm: true — nothing is emailed until confirmed. Field placement: page+x+y (percent, top-left origin) OR an anchor string, not both. After everyone signs, retrieve the sealed PDF with swiftsign_download_signed_pdf.
