assinafy

assinafy_check_fields

Prepare template values or collect field placements. list finds reusable definitions; get inspects one field; validate checks values without creating a document. Match definitions to template placement field_id, ask about ambiguous names, and check each validation result's success before requesting signatures.

assinafy_delete_document

Delete a document only when the user's instruction explicitly authorizes deletion. Inspect its current state first; Assinafy enforces which documents may be deleted.

assinafy_download_document

Retrieve bytes only when needed. artifact downloads original (default), certificated, certificate-page, pades or bundle; wait for certificated status and artifact availability before downloading the signed PDF. page downloads a preview using a page_id returned by find_documents. Results contain base64 bytes.

assinafy_find_documents

Find a document or check signing progress. Use list to search; get to inspect status, assignment, signer IDs and artifacts; activities for the event timeline; notifications for WhatsApp delivery history. Read before retrying a send or following up. 100% signatures does not mean certification is finished.

assinafy_find_signers

Resolve a recipient to a workspace signer ID. list searches the directory; get inspects a known signer. Check exact contact details and ask about ambiguous matches before sending invitations.

assinafy_find_templates

Discover saved templates before requesting signatures. list returns roles, pages, field_id and placement labels; get inspects one template where the compatibility endpoint is supported. Match field names with check_fields. Template authoring stays in Assinafy.

assinafy_follow_up_assignment

Follow up on an existing assignment after checking find_documents. resend sends a reminder to one authorized pending signer and may consume notification credits. set_expiration changes the expiry using an explicit RFC 3339 timestamp. Use returned document, assignment and signer IDs; never repeat a reminder just because progress is unchanged.

assinafy_place_fields

Open a visual editor to place signature, initials, date and input fields on a metadata_ready document, then send it with method collect. Takes the from_document arguments except method and entries. Sends nothing by itself: in apps-capable hosts the user places fields and presses Send; other clients get page sizes and field IDs as text to build entries.

assinafy_prepare_document

Prepare a PDF before requesting signatures. upload accepts PDF bytes and returns a document ID without invitations. rename changes a document's name before an assignment exists. Continue with find_documents and request_signatures action from_document.

assinafy_request_signatures

Send a document for signature using exactly one source. from_pdf uploads new PDF bytes, waits for processing and creates or reuses email signers. from_document uses an existing document_id and signer IDs; inspect the document first and do not repeat an existing assignment. from_template generates a document and assignment from a saved template; discover roles and field IDs first. These actions send invitations and can consume credits: use recipients authorized by the user. After a partial failure, inspect the retained document ID and continue from_document instead of uploading again.

assinafy_review_signature_request

Preview a request_signatures from_document call without sending anything: same arguments, checked against the document and signers. Use it when the user wants to review before sending. Apps-capable hosts render a card whose Send button performs the request; other clients get the summary as text, and the request is sent only after the user confirms.

assinafy_save_signer

create adds a workspace contact without sending invitations; find_signers first to avoid duplicates. update corrects a shared contact subject to Assinafy's verification restrictions. Changing an unverified channel invalidates old links; follow up only after the correction succeeds and the user has authorized a reminder.

assinafy_show_document

Show a status card for one known document: its status, who has signed, who is still pending and when it expires. Apps-capable hosts render it with a reminder button; other clients get the same summary as text. Resolve the document with assinafy_find_documents first.

assinafy_verify_document

Verify a signed document using its actual Assinafy SHA-1 signature hash. Public lookup; requires no workspace connection and sends no credential upstream.

Assinafy — questions

Answers built from our own checks of this server.

What can Assinafy do?

It exposes 14 tools, read directly from the server on our last check. Among them: assinafy_check_fields, assinafy_delete_document, assinafy_download_document, assinafy_find_documents, assinafy_find_signers, assinafy_find_templates and 8 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Assinafy working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 533 ms. The bar chart above shows every period we have measured.

How do I connect Assinafy?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Assinafy need an API key?

No. Assinafy completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 14 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Assinafy?

It answers our handshake in 533 ms on average, which is faster than 23% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Assinafy open source?

Yes — it is published under the MIT licence and 3 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
