- 02Draft monitoring agents in plain English
- 03Draft execution permissions for owner approval
- 04List and inspect account agents
- 05Pause, resume, edit, or remove agents
- 06Review notifications and execution history
Use cases
- 01Check DeFi positions in a wallet
- 02Monitor an Aave health factor or LP range
- 03Draft position alerts or follow-up actions

MCP support
It exposes tools for public wallet reports, agent drafts, and execution-permission drafts; its account endpoint also supports managing account agents. The server uses Streamable HTTP.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Tools
3| Parameter | Type | Required | Description |
|---|---|---|---|
| wallet | string | No | Optional. The owner's EVM (0x…) or Solana address, when you know it: then only that wallet can claim the draft. Omit it and the draft is bound to the first wallet that signs on the review page. |
| request | string | Yes | The complete condition or recurring schedule in plain English, 8 to 2000 characters, and for Prepare the action to run when it fires. There is no clarification round trip: an ambiguous or unwatchable request is a 422 with the reason, so rephrase and call again. |
| autonomy | enum | No | notify (default): the owner is told when it fires. prepare: the action in the request is stored and pre-planned on fire as an unsigned plan for the owner to sign. A request that includes an action must explicitly choose prepare; otherwise it is refused as autonomy_mismatch, not silently downgraded. Execute is not available here; it needs a Shield mandate.notify | prepare |
Details
From the project READMESigno 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.
Addresses
| Address | Sign-in | Tools |
|---|---|---|
https://app.signo.fi/api/mcp | None | 3 tools: read a public wallet report, draft an agent, draft an Execute permission |
https://app.signo.fi/api/mcp/account | Your Signo account (OAuth, wallet sign-in) | The same 3, plus 6 to list, read, pause, resume, edit and remove your own agents |
Both speak MCP over Streamable HTTP. Official MCP Registry name: fi.signo/signo.

Tools
No sign-in:
| Tool | What it does |
|---|---|
wallet_insights_report | Reads a public report on any wallet, with the agents it suggests. Read-only. |
signo_draft_agent | Drafts a Notify or Prepare agent from plain English. Returns a review link for the owner. |
signo_draft_permission | Drafts 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:
| Tool | What it does |
|---|---|
signo_account_agents | Lists the agents on your account. |
signo_account_agent | Reads one agent's setup and its last check. |
signo_account_agent_history | Reads its notifications and Execute runs. |
signo_account_agent_status | Pauses or resumes it. |
signo_account_agent_update | Edits supported fields on Notify and Prepare agents. |
signo_account_agent_remove | Removes it and keeps its history. |
How a draft becomes an agent
- The assistant calls a draft tool and gets a private review link.
- The wallet owner opens the link, connects the wallet and links Telegram.
- 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.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
