## Which one, for what

### rotki MCP server (E)

Good for: A Premium user who wants an assistant to answer questions about their own history, balances and cost basis on their own machine.

Also in its favour:
- Open source

Watch for: The desktop endpoint at http://127.0.0.1:4445/mcp takes no token, because the session key is forced empty outside Docker, so any local process can call it while the server runs

### Rutter Accounting API (C)

Good for: Lenders, spend-management and fintech products that read ledgers alongside commerce and payment platforms, and that need writes an agent can retry safely.

Ahead on:
- Reliability, 67 against 50
- Security & auth, 36 against 20
- Payments & pricing, 20 against 10
- Maintenance & community, 62 against 35

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: Production prices are quote-only

## Verdicts

**rotki MCP server.** A read-only MCP server in the rotki desktop app, for Premium Basic at €25 a month and above. Privacy modes mask addresses and account names, but amounts, dates, assets and counterparties reach the connected assistant in every mode. The desktop endpoint takes no token, and the feature shipped in v1.44.0 on 21 August 2026.

**Rutter Accounting API.** Idempotency-Key header on writes, and prefer_sync writes that fall back to async after 30 seconds. Production prices are quote-only.

## Before you call either

### rotki MCP server

1. Ask the person to start the server under Settings > MCP in the desktop app, since it stays down until started, then connect to http://127.0.0.1:4445/mcp
2. Call info first. It works without Premium and reports whether an unlocked backend is connected
3. Call get_event_taxonomy before any aggregate over event_type, and sum on direction or event_group, since informational rows double count MEV and block rewards
4. Call refresh_analytics_data before query_sql, and check source.completeness and unpriced_rows before reporting any total
5. Check the privacy mode before answering from the data. Strict keeps amounts and dates, and raw sends addresses, hashes and notes verbatim

### Rutter Accounting API

1. Send X-Rutter-Version: 2024-08-31 on every call
2. Send an Idempotency-Key on every create so a retry after a timeout doesn't write twice
3. Use response_mode=prefer_sync and handle the 202 async_response anyway
4. Treat 452 as the ledger throttling you and 429 as Rutter's 500-per-10-seconds organisation limit
5. Keep access_token out of logged URLs. The docs only show it as a query parameter
