## Install

**Verdict: install** — No blocking findings and no open coverage gaps — safe to install as configured.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"slack\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"@jtalk22/slack-mcp\"\n      ],\n      \"env\": {\n        \"SLACK_TOKEN\": \"<YOUR_SLACK_TOKEN>\",\n        \"SLACK_COOKIE\": \"<YOUR_SLACK_COOKIE>\"\n      }\n    }\n  }\n}"
```
**Credentials it will ask for** (names only — Forge never holds a value):
- `SLACK_TOKEN` — Slack Token (optional)
- `SLACK_COOKIE` — Slack Cookie (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 2 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; runs locally and hosted.
- Floor 58, ceiling 58 (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.
