## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: estimate_self_employed_tax (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cpp_self_employed (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); gst_hst_registration_check (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,303 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 1,303 tokens to load them all
- tool set hash: 3e2c57a39308c42ce0ee5512e9755400
- badge: [![protogrid quality](https://protogrid.dev/badge/ca.freelancertax/freelancertax.svg)](https://protogrid.dev/servers/ca.freelancertax/freelancertax)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `cpp_self_employed`: Compute self-employed CPP contributions for a given year: base + enhanced contributions, CPP2 (second ceiling), total payable, and the tax-deduction vs tax-credit split that goes on the T1 (Schedule 8). Quebec residents pay QPP instead — use estimate_self_employed_tax with province QC for QPP.
- `estimate_self_employed_tax`: Estimate a Canadian self-employed (sole proprietor) person's full tax bill: federal tax, provincial tax, CPP/QPP (incl. CPP2/QPP + QPIP for Quebec), total, after-tax income and effective rate. Fully verified provinces: ON, BC, AB, MB, SK, NS, NB, QC. Other provinces/territories return an honest federal+CPP-only partial estimate flagged supported:false.
- `get_tax_deadlines`: Upcoming CRA tax deadlines for Canadian freelancers / self-employed individuals (filing, payment, GST/HST, RRSP, quarterly instalments), each on its CRA effective date with the weekend next-business-day rule applied. Also available as a subscribable calendar feed.
- `gst_hst_registration_check`: Check whether a Canadian small business / freelancer must register for GST/HST under the $30,000 small-supplier tests (single-quarter test and rolling four-quarter test), with the exact mechanics of when to charge and the registration deadline. Set is_rideshare true for taxi/ride-share drivers (they must register from the first fare).
- `gst_quick_method_compare`: Compare the GST/HST Quick Method against the regular method for a Canadian small business: eligibility (revenue ceiling + excluded professions), remittance under each method, and which one keeps more money. Annual figures.
- `instalment_plan`: Determine whether a Canadian individual must pay quarterly income-tax instalments (the $3,000 / $1,800-Quebec net-tax-owing tests) and compute all three CRA payment options (no-calculation, prior-year, current-year) as quarterly schedules with a suggested no-interest choice. Per the CRA's instalment calculation chart, 'net tax owing' EXCLUDES CPP contributions and EI premiums payable — pass those separately as cpp_payable and they are added to the instalment amounts only (chart line 24), never to the threshold test.
