Alpaca Trading API integration for Model Context Protocol (MCP)
Nothing to run from here
Tallyfern Rates (Canada) is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http tallyfern-rates-canada-mcp https://mcp.tallyfern.com/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
5 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Apply the CRA's $30,000 small-supplier tests (single calendar quarter and four consecutive calendar quarters) to taxable revenue by calendar quarter. Says whether the person must register for the GST/HST, when they stop being a small supplier, the effective date of registration, and headroom for next quarter. Most businesses only (not charities/public service bodies).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| quarters | array | yes | Consecutive calendar quarters, no gaps (use 0 for quarters with no sales). |
| taxiOrRideshare | boolean | no | True if self-employed taxi or commercial ride-sharing driver (must register regardless). |
Current GST/HST rate for a Canadian province or territory (or all 13), with the PST/QST rate CRA lists for reference. From CRA's 'Charge and collect the GST/HST' table.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| province | string | no | Province or territory code or name, e.g. "ON", "Ontario", "QC", "Yukon". |
CRA reasonable per-kilometre allowance rates for employer-paid vehicle allowances (2026 default; 2025 also available): first 5,000 km and after, provinces vs territories. Optionally calculates the allowance for a number of business kilometres.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| year | number | no | Calendar year (2026 or 2025). Default 2026. |
| province | string | no | Province or territory code or name, e.g. "ON", "Ontario", "QC", "Yukon". |
| kilometres | number | no | Business kilometres in the calendar year, to calculate an allowance. |
CRA simplified-method rates (latest published tax year): flat meal rate per meal and maximum per day, and vehicle cents/km by province or territory where travel begins. These apply to moving expenses, northern residents deductions and medical travel, not to employer per-diems. Optionally calculates amounts.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| province | string | no | Province or territory where the travel begins. |
| kilometres | number | no | Kilometres driven, to calculate a vehicle amount (needs province). |
| meals | integer | no | Number of meals. |
| days | integer | no | Number of days (caps meals at the daily maximum). |
Plain-language basics for Ontario businesses: the 13% HST rate, the $30,000 small-supplier threshold, the 29-day registration deadline and place-of-supply rule, with CRA sources.

Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 0.2.0.
