Signo MCP server

Signo gives your AI assistant tools to set up agents that watch DeFi positions and alert you on Telegram. An agent can watch an Aave health factor, an LP range, a Pendle maturity or idle cash, and prepare the next step for you to sign.

The assistant only drafts. The wallet owner reviews every draft and signs it in Signo. The assistant never gets wallet keys or spending rights.

This repository is the public listing for Signo's hosted MCP server: its registry entry, setup snippets and example prompts. The server runs at app.signo.fi. There is nothing to install or build.

Tools

No sign-in:

ToolWhat it does
wallet_insights_reportReads a public report on any wallet, with the agents it suggests. Read-only.
signo_draft_agentDrafts a Notify or Prepare agent from plain English. Returns a review link for the owner.
signo_draft_permissionDrafts an inactive Execute permission on X Layer or Arbitrum. The owner authorizes it onchain. Execute is in early access; a wallet without access gets a Prepare draft instead.

With your Signo account, also:

ToolWhat it does
signo_account_agentsLists the agents on your account.
signo_account_agentReads one agent's setup and its last check.
signo_account_agent_historyReads its notifications and Execute runs.
signo_account_agent_statusPauses or resumes it.
signo_account_agent_updateEdits supported fields on Notify and Prepare agents.
signo_account_agent_removeRemoves it and keeps its history.

How a draft becomes an agent

  1. The assistant calls a draft tool and gets a private review link.
  2. The wallet owner opens the link, connects the wallet and links Telegram.
  3. The owner signs once. Only then does the agent run.

An Execute permission sets one action, one token, a limit per firing, a lifetime limit and an expiry. The Signo Shield contract checks every firing against those limits. The owner can revoke it onchain at any time.
