wFirma MCP

Unofficial, read-only MCP server for the wFirma API v2 (api2.wfirma.pl). Gives MCP-compatible AI assistants typed, read-only access to company data, invoices, contractors, expenses, and payments — with credentials that never leave your machine and no commercial middleware between you and wFirma.

Not affiliated with wFirma. "wFirma" is a trademark of its respective owner.

Tools (9, all read-only)

ToolEndpoint
wfirma_list_companiesGET /user_companies/find
wfirma_list_invoicesGET /invoices/find
wfirma_get_invoiceGET /invoices/get/{id}
wfirma_list_contractorsGET /contractors/find
wfirma_get_contractorGET /contractors/get/{id}
wfirma_list_expensesGET /expenses/find
wfirma_get_expenseGET /expenses/get/{id}
wfirma_list_paymentsGET /payments/find
wfirma_get_paymentGET /payments/get/{id}

Every company-scoped tool requires the internal companyId returned by wfirma_list_companies. A Polish NIP is not accepted as a company id.

Why read-only

The server intentionally contains no add, edit, delete, send, fiscalization, KSeF, or payment-mutation operation. The full list of excluded categories, reviewed against the official documentation at doc.wfirma.pl, is recorded in coverage-manifest.json. If you need writes, use wFirma's own tooling — not this server.

Setup

Credentials

wFirma API keys are created in your wFirma panel (Integrations → API). Required environment variables:

  • WFIRMA_ACCESS_KEY
  • WFIRMA_SECRET_KEY
  • WFIRMA_APP_KEY

See .env.example. Never commit real values.

Build
pnpm install
pnpm build      # → dist/index.js (self-contained esbuild bundle)
pnpm test       # all HTTP traffic is mocked; no live account needed
Claude Desktop / any stdio MCP client
{
  "mcpServers": {
    "wfirma": {
      "command": "node",
      "args": ["/absolute/path/to/wfirma-mcp/dist/index.js"],
      "env": {
        "WFIRMA_ACCESS_KEY": "your-access-key",
        "WFIRMA_SECRET_KEY": "your-secret-key",
        "WFIRMA_APP_KEY": "your-app-key"
      }
    }
  }
}
Claude Code / Cursor (scope: project)
claude mcp add wfirma -- node /absolute/path/to/wfirma-mcp/dist/index.js

Design notes

  • No runtime dependencies beyond the MCP SDK and zod. The client uses Node's stdlib https with a hard 20s timeout and a bounded response-size guard.
  • Fail-closed error taxonomy. Missing credentials, non-numeric company ids, oversized responses, and auth failures each raise a distinct wfirma_* error code instead of a generic failure.
  • No PII in logs. Tool parameters are never logged.
  • Coverage manifest. coverage-manifest.json maps every tool to its endpoint, risk class, and the test that proves it; a CI test enforces the manifest stays in sync with the source.
