JaKonto MCP

JaKonto's MCP server provides AI agents with read-only access to Danish accounting data from e-conomic and Billy. It exposes tools to list connections, invoices, VAT by quarter, profit and loss, and manage bookkeeping proposals. The server authenticates via API key and ensures the agent cannot write to the source accounting systems.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http jakonto-mcp https://jakonto.dk/api/v1/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add jakonto-mcp --url https://jakonto.dk/api/v1/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable jakonto-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "jakonto-mcp": {
      "url": "https://jakonto.dk/api/v1/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "jakonto-mcp": {
      "type": "streamableHttp",
      "url": "https://jakonto.dk/api/v1/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start jakonto-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "jakonto-mcp": {
      "type": "http",
      "url": "https://jakonto.dk/api/v1/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http jakonto-mcp https://jakonto.dk/api/v1/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://jakonto.dk/api/v1/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "jakonto-mcp": {
      "serverUrl": "https://jakonto.dk/api/v1/mcp"
    }
