Yousign MCP server

What the model can do

Yousign (Youtrust) e-signature: signature requests by status, name, label or date with their signers and who has signed, contacts and templates. Can create a draft request and add or remove its signers, change it, send it for signing, remind a signer or approver, pause, resume, reactivate, cancel or delete it, and create, change or delete a contact.

Acts, when you ask

These change something in Yousign. The model is told to use them only when you ask for exactly that, and each one is granted by name: per team on a shared connection, by the owner on a personal one.

Connect it

First connect Yousign on Dashboard → Connections, then add Memtro to your client once. The Yousign tools appear alongside the tools of everything else you have connected; nothing is configured per connector.

Who may use it

The key identifies the person, and the server offers that person the tools they may use everywhere else in Memtro. A shared Yousign connection is used by the teams an administrator granted it to, tool by tool, on the Permissions page; a personal connection is used by its owner alone, and its tools that act stay off until the owner allows them. See Teams and permissions and Connectors.

Ask it like this

• › Has the Northwind renewal contract been signed yet?
• › Which signature requests are still waiting on someone, and on whom?
• › Who signed the Brightwave Ltd NDA, and when?
• › Which requests expired or were declined last month?
• › Remind the Northwind finance director to sign the renewal

Questions

Is this an official Yousign MCP server?

No. It is Memtro's MCP server with Memtro's Yousign connector behind it: the connector reads Yousign through its API with the credentials you connect on Dashboard → Connections, and Yousign publishes nothing here. The same endpoint carries every other system you connect and Memtro's memory tools.

What does it cost?

Nothing on top of Memtro. One price per organisation by its number of users, from $50 a month for up to 10 users after a 7-day free trial, with every connector, the MCP server, jobs and memory included. You bring your own model keys.

Can it change anything in Yousign?

Only when you ask, and only what it has been granted: create a draft signature request (stays a draft, with email delivery off, until somebody sends it in Yousign); create a contact; send a Yousign signature request for signing (activate it); cancel a Yousign signature request; remind a signer to sign; remind an approver to approve; add a signer to a Yousign signature request; remove a signer from a Yousign signature request; change a Yousign signature request's name, delivery, order, expiry or decline setting; delete a Yousign signature request; pause a Yousign signature request; resume a paused Yousign signature request; reactivate an expired Yousign signature request with a new expiry; change a Yousign contact; delete a Yousign contact. Every other tool reads, searches or lists. An administrator grants each acting tool by name per team, and a personal connection acts only after its owner allows it.

Which clients work?

Any MCP client that speaks Streamable HTTP: Claude Code, Cursor, Claude Desktop, OpenCode, Codex, Zed, Windsurf, Cline and the Anthropic and OpenAI SDKs. There is no local process to run; the server is remote and authenticated with your key.
