## Tools

2 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `firefly_list_operations` — List available Firefly III operations, optionally filtered by entity.
- `firefly_get_schema` — Get the parameter schema for a specific operation.

## Install

**Verdict: install** — No blocking findings and no open coverage gaps — safe to install as configured.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"firefly\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"@yakupemreyerli/firefly-mcp\"\n      ],\n      \"env\": {\n        \"FIREFLY_API_TOKEN\": \"<YOUR_FIREFLY_API_TOKEN>\"\n      }\n    }\n  }\n}"
```
**Credentials it will ask for** (names only — Forge never holds a value):
- `FIREFLY_API_TOKEN` — Firefly API Token (required)
Placeholders only. Forge never holds, brokers, or transmits a credential value — replace each <YOUR_NAME> in your own config file. Do not send a value back to Forge; no Forge endpoint accepts one.
- This entry needs 1 credential (1 required). The generated config carries placeholders, so it will fail in the editor rather than at runtime if they are left unset.

## Blast radius

Moderate blast radius — holds an api key; runs on your machine.
- Floor 23, ceiling 23 (tier: moderate)
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
