MCP server for capturing and classifying daily expenses, built with Node.js and TypeScript, using Postgres and optional LLM-based classification.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
budget.statusDevuelve spent/budget/remaining por sobre al día indicado.
expense.captureCrea un borrador de gasto y devuelve preguntas faltantes para poder confirmarlo.
expense.confirmValida y persiste un borrador como Expense. Clasifica y devuelve estatus de sobres (envelopes).
expense.correctActualiza la categoría (categoryId) de un Expense ya persistido y aprende una heurística (Merchant.defaultCategoryId o ClassificationRule).
expense.listLista los gastos del usuario (rango opcional por fecha).
report.monthlyTotales por categoría y top merchants para un mes YYYY-MM.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
6/6 tools missing one or more hints — budget.status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); expense.capture (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); expense.confirm (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +3 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool handlers catch errors
Only 0/6 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 5 high severity in production deps — @hono/node-server@1.14.0 (high), hono@4.5.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
