E MCP Server

MCP server for the Estonian e-arveldaja (RIK e-Financials) accounting API. That is what the e mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.

The short version

MCP server for the Estonian e-arveldaja (RIK e-Financials) REST API. 127 tools on the compatibility-preserving standard profile, 16 workflow prompts, 15 resources. Works with any MCP client — Claude Code, Codex CLI, Gemini CLI, Cursor, Windsurf, Cline, and others.

What it needs from you

Configuration is passed through the environment: EARVELDAJA_API_KEY_ID, EARVELDAJA_API_PUBLIC_VALUE, EARVELDAJA_API_PASSWORD. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Getting it running

The server ships on npm as e-arveldaja-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

How it compares

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by iseppo; worth a glance at recent repository activity before you build anything load-bearing on it.

Things to watch

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
