## 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    \"google-knowledge-graph\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"@houtini/google-knowledge-graph-mcp\"\n      ],\n      \"env\": {\n        \"GOOGLE_KNOWLEDGE_GRAPH_API_KEY\": \"<YOUR_GOOGLE_KNOWLEDGE_GRAPH_API_KEY>\"\n      }\n    }\n  }\n}"
```
**Credentials it will ask for** (names only — Forge never holds a value):
- `GOOGLE_KNOWLEDGE_GRAPH_API_KEY` — Google Knowledge Graph API Key (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.
