## Tools

18 declared. Statically extracted from the shipped source — a floor on the surface, not a census.

## Install

**Verdict: review** — Installable, but 1 thing to check first: No publisher has proved control of this listing; it is indexed, not vouched for.
**Cautions** (coverage gaps and advisories — never blocking)
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"kybase\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"kybase-mcp\"\n      ],\n      \"env\": {\n        \"GOOGLE_API_KEY\": \"<YOUR_GOOGLE_API_KEY>\",\n        \"OPENAI_API_KEY\": \"<YOUR_OPENAI_API_KEY>\",\n        \"DATABASE_URL\": \"<YOUR_DATABASE_URL>\"\n      }\n    }\n  }\n}"
```
**Credentials it will ask for** (names only — Forge never holds a value):
- `GOOGLE_API_KEY` — Google API Key (optional)
- `OPENAI_API_KEY` — OpenAI API Key (optional)
- `DATABASE_URL` — Database URL (optional)
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 3 credentials (0 required). The generated config carries placeholders, so it will fail in the editor rather than at runtime if they are left unset.

## Blast radius

Extensive blast radius — deletes data; holds an api key.
- Floor 56, ceiling 56 (tier: extensive)
- 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.
