accounted-mcp

Connect Claude Desktop, Claude Code, or another stdio MCP client to your Accounted bookkeeping account.

This zero-dependency bridge forwards JSON-RPC over stdio to the hosted Accounted MCP server. New connections receive the accounted_* tool namespace. Existing gnubok-mcp configurations remain supported separately.

Setup

1. Create an API key in Accounted under Settings > API.
2. Add the bridge to your MCP client:

{
  "mcpServers": {
    "accounted": {
      "command": "npx",
      "args": ["-y", "accounted-mcp"],
      "env": {
        "ACCOUNTED_API_KEY": "gnubok_sk_test_...",
        "ACCOUNTED_CLIENT": "claude-desktop"
      }
    }
  }
}

The credential value retains the legacy gnubok_sk_* wire prefix for backward compatibility. Only the MCP integration is being renamed in this release.

Environment variables

Variable	Required	Default	Description
ACCOUNTED_API_KEY	yes	none	Your existing Accounted API key.
ACCOUNTED_URL	no	Accounted hosted MCP endpoint	Override for self-hosted Accounted. The bridge adds tool_namespace=accounted when omitted.
ACCOUNTED_CLIENT	no	none	Telemetry-only distribution marker such as claude-desktop.

The API key scopes determine which tools are visible and callable. Write tools stage pending operations for explicit approval before anything is booked.

OAuth connector (no API key, no account needed up front)

Clients with OAuth support connect directly without this bridge and without an existing API key. The sign-in screen lets a new user create the Accounted account (BankID or e-mail), and company setup then continues in the conversation through the onboarding skill and accounted_create_company:

https://app.accounted.se/api/extensions/ext/mcp-server/mcp?tool_namespace=accounted

# Claude Code
claude mcp add --transport http accounted \
  "https://app.accounted.se/api/extensions/ext/mcp-server/mcp?tool_namespace=accounted"

# OpenAI Codex
codex mcp add accounted --url \
  "https://app.accounted.se/api/extensions/ext/mcp-server/mcp?tool_namespace=accounted"

Claude.ai and Claude Desktop: Settings > Connectors > Add custom connector, paste the URL, then in step 2 choose:

• Authentication: "Required when the server asks." Claude auto-detects "None" because the server answers the handshake without credentials; with "None" the first company-scoped call shows an error instead of the sign-in.
• OAuth client: "No client ID, register one automatically" (DCR). The server does not advertise Anthropic's hosted client metadata (CIMD) yet.
• No additional headers; transport stays Streamable HTTP.

The connector works before you connect (documentation tools); the first company-scoped call opens the sign-in prompt, where a new user creates the account.

Compatibility

The legacy gnubok-mcp package, environment variables, endpoint behavior, and gnubok_* tool aliases remain supported. Existing installations do not need to change.

Releasing

The package is published to npm by the Publish MCP bridges to npm workflow (.github/workflows/npm-publish.yml), never by hand:

1. Bump version in packages/accounted-mcp/package.json.
2. Merge the change to main.
3. The workflow compares the new version with the registry and, if it is not there yet, runs npm publish --provenance --access public. A version that already exists on npm is skipped, so other package.json edits are harmless.

The workflow needs the repository secret NPM_TOKEN: an npm granular access token with read and write access to accounted-mcp and gnubok-mcp, with two-factor bypass enabled so CI can publish. npm caps the lifetime of such tokens (90 days at the time of writing), so rotate the secret before it lapses. Without the secret the run fails at its first step. The workflow can also be started from the Actions tab, for one package or both, with a dry-run option that packs and validates without publishing.
