Health Canada Drugs

Health Canada Drugs — the Canadian Drug Product Database

Every drug authorised for sale in Canada: DIN, brand name, active ingredients with strengths, dosage form, route, market status and the company behind it.

Part of Pipeworx — an MCP gateway connecting AI agents to 1881+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Scope — Canada, and only Canada

This is Canadian marketing authorisation. US approvals and labels are openfda and dailymed; the two are separate regulatory acts and a drug can be authorised in one and not the other. Tools are prefixed health_canada_* so they never win a generic drug question.

Tools

Tool	Answers
health_canada_search_drugs	Is Tylenol approved in Canada? — brand-name search, returns DINs
health_canada_drug_detail	What is DIN 01933655? — ingredients, strengths, form, route, status
health_canada_drugs_by_ingredient	Which Canadian drugs contain acetaminophen?

Data source

• https://health-products.canada.ca/api/drug/ — Health Canada Drug Product Database.

Things the next person would otherwise rediscover

• An unrecognised filter is silently ignored and returns the ENTIRE 15 MB database, with HTTP 200 and the drug you asked about somewhere inside it. The query parameter is brandname; the JSON field is brand_name. Measured: ?brandname=ACTIFED → 3,576 bytes; ?brand_name=ACTIFED → 15,040,036 bytes; ?search=ACTIFED → 15,040,036 bytes. Matching the response field name is the natural guess and it is the wrong one. This pack whitelists the working parameters and throws rather than send an unknown one.
• id= means different things on different endpoints. On /drugproduct/, /activeingredient/, /status/, /form/ and /route/ it is the drug code. On /company/ it is the company code. Drug 11685 is ACTIFED PLUS CAPLET (Glaxo Wellcome); company 11685 is DERMAL DEFENSE, INC. of Michigan. Passing a drug code to /company/ returns a real record for an unrelated firm with nothing to signal the switch — so the company is read from the drug's own record and /company/ is never called with a drug code here.
• The upstream returns a bare object for a single hit and an array otherwise. Code that assumes an array drops every single-result lookup.
• DIN leading zeros are significant — 01933655 is not 1933655.
• No working company-name filter. Both companyname and company_name return the full 1.4 MB company list, so company search is deliberately not offered rather than shipped as a 1.4 MB-per-call tool.
• A "Cancelled Post Market" status is not a safety withdrawal — Health Canada retains records for products no longer marketed, for any reason.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "health-canada-drugs": {
      "url": "https://gateway.pipeworx.io/health-canada-drugs/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/health-canada-drugs/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1881+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/health_canada_search_drugs \
  -H 'Content-Type: application/json' \
  -d '{"brand_name":"ACTIFED"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/health_canada_search_drugs. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "health-canada-drugs": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-health-canada-drugs"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-health-canada-drugs

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Health Canada Drugs data" })

The gateway picks the right tool and fills the arguments automatically.
