On 2026-10-26 the server answered initialize and tools/list without a sign-in. First answer in 37 ms.

• Its tools do every use case we checked: track agent spending in a persistent double-entry ledger; generate balance sheets and income statements on demand.
• Checked on 1 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• submit_directive

  Submit one Beancount directive (open, transaction, close, balance, price, note, document — any type). Paid, except your first 20 accepted writes per registered key, which are free (this specific tool only — submit_batch is always paid…

• validate_directive

  Free dry-run: parse+book text against your full history without persisting or charging anything. Still requires a valid signature (identity/replay protection is not a billing concern).

• submit_batch

  Submit up to 1000 directives atomically — all persist together or none do. Priced 10x a single write, regardless of batch size within the cap. Always paid — the free-trial allowance (see submit_directive) applies to single writes only…

• list_directives

  List raw directives (optionally filtered by account/date range). No booking involved — cheapest paid tool. `since`/`until` are ISO date strings (YYYY-MM-DD). Your first 2 calls per registered key are free (independent of the…

• list_accounts

  List all opened accounts with their currency constraints and booking method. No booking pass involved. Your first 2 calls per registered key are free (a separate allowance from list_directives' and the report tier's — see those tools).

• get_account_balance

  Balance of a single account. Settles at the same fixed price whether the account exists or not — an "unknown account" answer is still a valid, billable response (no per-error pricing discount). No free-trial allowance for this specific…

• export_ledger

  Export the full ledger as literal Beancount text — a portable snapshot for fava/bean-report/etc., not the live store. Shares a combined free allowance of 2 with get_balance_sheet, get_income_statement, and get_trial_balance (the "report…

• get_balance_sheet

  Full realize() balance sheet — often served from cache. Settles at the same fixed price regardless of cache hit/miss. Shares a combined free allowance of 2 with export_ledger, get_income_statement, and get_trial_balance (the "report…

• get_income_statement

  Income statement, period-scoped by since/until (ISO date strings, both optional — omitted means whole history). Always books full history first, then clamps the output to the requested period (never filters input dates — see reports.py…

• get_trial_balance

  Trial balance, period-scoped same as income statement — same underlying compute, priced and audited as its own resource. Shares a combined free allowance of 2 with export_ledger, get_balance_sheet, and get_income_statement (the "report…

• register

  Generate a new Ed25519 keypair for ledger identity. Returns the private key exactly once — it is never stored server-side and cannot be recovered if lost. This is a SEPARATE keypair from whatever wallet you use to authorize x402 payments…
