# How I’d use a Wealthsimple MCP

The Wealthsimple MCP workflows I would use: read-only financial context, strategy monitoring, explicit approvals and permissions enforced by Wealthsimple.

Danny, this is something I’d genuinely use. I already use agents for research, coding and daily work, and I’d love to connect them to Wealthsimple through an official MCP server.

The appeal is being able to build my own workflows around my accounts, using the agents I choose, while Wealthsimple enforces what they can access and do. I’d start with two workflows.

## Everyday finances, starting read-only

“What changed since payday, what bills are coming up, and how much cash is left after keeping the buffer I chose?”

The agent would read only the Wealthsimple chequing, card and investment accounts I authorized, then give me a breakdown with dates and the records behind its numbers. It should distinguish available cash from invested assets, separate pending from posted transactions, and account for existing commitments without double-counting them.

I’d also want a clear distinction between confirmed upcoming payments and bills estimated from past activity. Missing accounts, stale data or uncertain amounts should be visible, not quietly filled in by the model.

That alone would be a useful first release. No trading or money movement required.

Later, I’d want to ask it to prepare a payday plan: cover bills, keep my buffer, and propose what to save or invest. I’d review the amounts, source and destination accounts, fees, currency conversion and timing in Wealthsimple before anything moves.

For a fixed routine I approve, Wealthsimple should run the rule and report the result. An LLM shouldn’t have to remember to send money every Friday.

## A strategy-monitoring and trading workflow

I’d like to build an agent that monitors a strategy I’ve chosen, checks my holdings and open orders, and proposes a trade when my conditions match. I’d want a paper-trading environment to test that workflow before using real money.

The agent would explain what triggered the proposal and request an order preview from Wealthsimple. That preview should show the exact security and account, whether I’m buying or selling, the quantity, order type, any limit price, order duration, estimated fees and currency conversion. Wealthsimple should validate account eligibility, the trading session, settled cash and buying power rather than relying on the agent’s checks.

I’d approve the exact order in Wealthsimple, not just say yes in chat. That approval should be single-use and time-limited. Changing the order details should require fresh approval, and Wealthsimple should recheck the relevant conditions before submission.

After submission, the agent should report the actual status: open, partially filled, filled, rejected, cancelled or expired, with settlement tracked separately. I don’t want “submitted” presented as “done.”

Retries need the same care. Each action should have a stable request identifier, with Wealthsimple preventing duplicate execution. After a timeout, the agent should reconcile the original request, not place another trade because it missed the response.

## Permissions enforced by Wealthsimple

Reading accounts, preparing proposals, executing trades and moving money should be separate permissions. I’d want to choose the accounts, permitted assets, order types, per-action and cumulative limits, and when access expires. The agent should never be able to increase its own limits or approve its own requests.

Those restrictions need to hold even when the agent makes a mistake or follows a misleading instruction. A web page, document or transaction description should never count as authorization to trade or change permissions.

For multiple agents, I’d separate research, planning and execution, with distinct credentials and an overall shared allowance. Wealthsimple should enforce that allowance across pending and completed actions within the defined period. Two agents must not each spend the same remaining budget because they ask at the same time.

I’d also want to revoke access in Wealthsimple and see which agent accessed which data, what it proposed, what I approved and what actually happened.

Eventually, I’d be interested in unattended trading under a small, explicit mandate: no margin or external withdrawals, restricted assets, clear price and spending limits, and an expiry date. I’d need a way to block new orders immediately and see which existing orders remain open or have been successfully cancelled. That is a later step, not a launch requirement. These controls restrict the agent’s authority; they don’t guarantee it won’t lose money.

## Canadian accounts need Canadian context

CAD and USD should always be explicit. For registered accounts, I’d want the relevant contribution and withdrawal effects surfaced before approval, with account-specific rules rather than a generic “transfer money” action.

The interface should distinguish Wealthsimple’s own contribution records from my total contribution room across institutions. When information needed to establish room is missing, an automatic contribution should pause and ask me to resolve it, not proceed with an invented safe amount.

## Make it straightforward to build and connect

For developers, I’d want a small set of well-documented tools, structured results, timestamps, useful errors and a sandbox with test data and simulated order outcomes. A coding agent should be able to build and test a workflow without access to my real accounts.

I’d like the same core interface to work across compatible agents, with examples for Hermes, Cursor and Codex, rather than requiring one particular assistant.

Connecting should use Wealthsimple sign-in and scoped consent, not passwords or authentication codes pasted into chat. I should be able to grant only the data a workflow needs and understand what gets shared with my chosen agent or model provider. Read-only access still deserves careful privacy controls.

## Where I’d start

My first priority is excellent read-only access. Add a developer sandbox and paper-trading support before live order execution, then introduce orders approved in Wealthsimple. Expand money movement and standing permissions only after those foundations work reliably.

The value for me is the freedom to build around Wealthsimple without handing an agent unrestricted control of my finances. I’d be happy to walk through these workflows and help test an early version.
