Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Read documents, signature requests and templates; send, cancel and resend requests in SignRequest.
These three are never merged into one score: opinions, measurements and popularity are different things.

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
signrequest_list_documentsList documents of the team with status, signers state and signing log links. API: GET /documents/.
signrequest_get_documentGet one document by uuid: status, signrequest with all signers, signing log, attachments, and temporary download links (pdf). API: GET /documents/{uuid}/.
signrequest_search_documentsSearch documents by free text, name, signer email or status. API: GET /documents-search/.
signrequest_list_signrequestsList signature requests (the sent requests with their signers). API: GET /signrequests/.
signrequest_get_signrequestGet one signature request by uuid, with each signer's viewed, signed, declined and forwarded state. API: GET /signrequests/{uuid}/.
signrequest_list_templatesList document templates (use a template uuid with signrequest_send_document). API: GET /templates/.
signrequest_get_templateGet one template by uuid, with its signer placeholders. API: GET /templates/{uuid}/.
signrequest_list_teamsList the teams the token can see (name, subdomain, sandbox flag). API: GET /teams/.
signrequest_get_teamGet one team by subdomain. API: GET /teams/{subdomain}/.
signrequest_list_team_membersList team members with admin, owner and active flags. API: GET /team-members/.
signrequest_list_eventsList document events (sent, viewed, signed, declined, cancelled, bounced) and their callback delivery state. API: GET /events/.
signrequest_send_documentWRITE: creates a document and e-mails a signature request to the signers right away (not undoable except with signrequest_cancel_signrequest). Give exactly one source: a template uuid, a public file_from_url, or base64 file_from_content with file_from_content_name. API: POST /sig
signrequest_cancel_signrequestWRITE: cancels a signature request that is not fully signed or declined. Signers who have not signed can no longer open the document. Not undoable. API: POST /signrequests/{uuid}/cancel_signrequest/.
signrequest_resend_signrequest_emailWRITE: sends the signature request e-mail again as a reminder to every signer who did not sign yet but already got the e-mail. API: POST /signrequests/{uuid}/resend_signrequest_email/.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.2.3) reached the registry yesterday.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

Use your SignRequest account from Claude, Cursor, or any MCP client. Read documents, signature requests, templates, teams and events, and send, cancel or resend signature requests. Hosted, no local install: connect with your own credentials.

Add only the URL. 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 SignRequest credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/signrequest/
On first connect you provide a SignRequest team API token (SignRequest → Team settings → API). The server validates it and stores it per user. No keys go in config files.
