Read documents, signatures, contacts and credits; manage contacts and remove documents.
The publisher's own server: Ably MCP by usefulapi
Connects an assistant to an OKSign e-signature account to read documents, signers, contacts and credits, and to manage contacts and documents.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.usefulapi%2Foksign/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your OKSign credentials.

Connect your OKSign credentials to access your account through usefulapi.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
Pro covers this server only. Subscribe with oksign_upgrade (it returns a Stripe Checkout link). Cancel any time with oksign_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running oksign_upgrade before then undoes the cancel. Or write to [email protected].

Get credits and storage
The account's remaining credits (quantity), when they expire (validuntil), the plan (subscription), whether it is paid, and storage used (account_size) versus the maximum (max_account_size) in bytes. GET /v1/credits/retrieve.
Takes no parameters.
List users
The users of the OKsign account: name, email, mobile, role, status, language and the immutable signerid (use it to tell who signed). GET /v1/users/retrieve.
limitoffsetList email templates
The email templates defined in the account: id, name, subject, HTML body, reminder_days and repeat. GET /v1/email-templates/retrieve.
limitoffsetList contacts
The account's contact list: name, email, mobile, actingas (capacity) and group. GET /v1/contacts/retrieve.
limitoffsetList active documents
Documents in the account's Active Documents tab: docid, filename, creator, createdate, signatures required/valid, orgtoken, status (1 active, 10 briefcase, 11 document in a briefcase, 12 reusable, 14 template), viaapi and signed_docid when signed. OKsign allows this call only once every 3 minutes (429 otherwise). GET /v1/documents/active.
limitoffsetsignedorgtokenfilename_containsList signed documents
Documents uploaded through the API that were signed between two moments: signed_docid, source_docid, filename, signerid, signing source, signature counts, completed fields, credits per signer and timestamp. Keep the window short; OKsign allows this call only once every 3 minutes (429 otherwise). GET /v1/documents/signed.
endrequiredlimitstartrequiredoffsetList email and SMS delivery errors
Email and SMS delivery problems (hard_bounce, soft_bounce, blocked, spam, invalid_email, deferred) for signing invitations sent between two moments: recipient, source_docid, reason, orgtoken and timestamp. Only error events are reported. OKsign allows this call only once every 3 minutes (429 otherwise). GET /v1/webhooks/retrieve.
endrequiredlimitstartrequiredoffsetCheck a document exists
Whether a (signed) document still exists on the platform; returns its filename and whether it is a template. GET /v1/document/exists.
docidrequiredGet signed document metadata
Metadata of a signed document (pass the signed_docid): filename, size, signatures required/valid, who signed, and the values of all completed fields (can contain personal data). Metadata v2. GET /v2/metadata/retrieve.
signed_docidrequiredGet a document's form descriptor
The form descriptor of an uploaded document: its signature and form fields (type, page, position, signer, required, signing options) and the signing URL of each signer. The URLs let their holders sign, so share them only with the signer. GET /v1/formdesc/retrieve.
docidrequiredFind the source or signed copy of a document
Given a source_docid, the signed_docid of its signed copy (absent if not signed yet) and the timestamp; given a signed_docid, the source_docid. An empty result means the document never existed here or was removed. GET /v1/linkedlist/retrieve.
docidrequiredAdd or update contacts
WRITE: add contacts to the account's contact list, or update them when a contact with the same email AND name exists (its other fields are replaced). Existing contacts are never cleared. Contacts OKsign rejects are skipped and reported. POST /v1/contacts/upload.
contactsrequiredRemove contacts
WRITE: permanently remove contacts from the account's contact list. A contact is identified by its email AND name. Cannot be undone (re-add with oksign_upsert_contacts). POST /v1/contacts/remove.
contactsrequiredRemove a document
WRITE: permanently remove a (signed) document from the OKsign platform. This deletes the file and its pending webhook events and cannot be undone. A signed document removed right after its callback may answer 'Too soon': retry later. DELETE /v1/document/remove.
docidrequired100% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
