check_status
Check the current status of an envelope. Returns the envelope details including recipient signing status, document availability, and timestamps.
LABSCO SUMMARY
The audit certificate having its own download is the detail that matters — a signed PDF without its trail is a document, not evidence.
E-signature is only worth anything because of the audit record, and plenty of integrations expose the signed file while leaving the certificate somewhere in a web UI. Here it is a separate call, with an archive option that bundles both. The other thing this surface does well is state: every tool names the envelope state it requires, so an agent working a queue knows that voiding needs a sent envelope and deleting does not work on one — which is the difference between a clean refusal and a batch that half-completes. Worth remembering what create_and_send actually does: it sends. A signature request goes to a real person the moment that call returns.
What it is
An e-signature client covering the envelope lifecycle: create and send, track status, download the signed output and its audit trail, plus templates, webhooks and embeddable signing.
What you get
- create_and_send does the whole opening move in one call — envelope, PDF, signer, sent — while send_envelope covers the case where a draft already exists.
- check_status returns recipient signing state, and list_envelopes filters by status so a queue can be worked.
- Three download paths with different contents: the signed PDF, the audit certificate with its full trail, and a ZIP archive containing both plus related documents.
- The state machine is enforced and each tool says so: download_signed needs a completed envelope, void_envelope needs a sent one, and delete_envelope only accepts drafts and voided envelopes.
- get_embed_url returns a signing URL for an iframe, so signing can happen inside your own product.
- Webhooks are managed here rather than in a console — create, list and delete, with deletion stopping events immediately.
- Templates hold pre-placed fields, and create_from_template can pre-fill values and send in the same call.
Requirements
SIGNFORGE_API_KEY.
Setup effort
One command plus a key — SIGNFORGE_API_KEY="<YOUR_SIGNFORGE_API_KEY>" npx -y @signforge/mcp-server
USE CASES
01
Getting a document signed from where you already are
Create the envelope with the PDF and signer and send it in one call, then check the recipient's signing state rather than waiting for an email.
02
Collecting the evidence, not just the document
Download the signed PDF and its audit certificate — or the archive containing both and everything related to the envelope.
03
Sending the same agreement repeatedly
Work from a template with its fields already placed, pre-filling the values that change and sending in the same call.
04
Stopping something already in flight
Void an envelope that has been sent, which cancels the pending signatures, and delete only what is still a draft or already voided.
05
Signing inside your own product
Generate an embeddable signing URL for an iframe, and register a webhook so envelope events arrive without polling.
15 tools
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
create_and_send
Create an envelope with a PDF document, add a signer, and send it for e-signature. Returns the envelope ID and a signing URL. Provide either a local file path (pdf_path) or base64-encoded PDF content (pdf_base64).
create_from_template
Create an envelope from a template. Optionally pre-fill field values and send immediately. The template's fields will be mapped to the provided recipients.
create_webhook
Create a webhook to receive real-time notifications for envelope events. Events include: envelope.sent, envelope.viewed, envelope.signed, envelope.completed, envelope.expired, envelope.voided, envelope.declined.
delete_envelope
Permanently delete an envelope. Only draft and voided envelopes can be deleted.
delete_webhook
Delete a webhook by its ID. The webhook will stop receiving events immediately.
download_archive
Download a ZIP archive containing the signed PDF, audit certificate, and all related documents for a completed envelope.
download_certificate
Download the audit certificate PDF for a completed envelope. The certificate contains the full audit trail with timestamps and IP addresses.
download_signed
Download the signed PDF document for a completed envelope. The envelope must be in 'completed' status. Saves the file to the specified output path.
get_embed_url
Generate an embeddable signing URL for an envelope. This URL can be embedded in an iframe for in-app signing experiences.
list_envelopes
List your envelopes with optional filtering by status. Returns envelope summaries including titles, statuses, and recipient information.
list_templates
List your reusable document templates. Templates contain pre-placed fields and can be used to quickly create envelopes.
list_webhooks
List all configured webhooks for your account.
send_envelope
Send a draft envelope for signing. The envelope must be in 'draft' status with at least one recipient and one field configured.
void_envelope
Void (cancel) an active envelope. The envelope must be in 'sent' status. All pending signatures will be cancelled and signers will be notified.
