## Tools

5 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `infer_contract` — Generate draft ContractGate YAML from real JSON sample events via POST /contracts/infer. Does not persist. Review and write the YAML to contracts/<name>.yaml be
- `validate_events` — Validate events. Pass contract_id to hit POST /v1/ingest/{id} (dry_run defaults true — no audit, quarantine, or usage). Pass yaml_content to hit POST /playgroun
- `deploy_contract` — POST /contracts/deploy — find-or-create by name, insert YAML as stable, deprecate prior stable. 409 if that (name, version) exists: bump version in the YAML. Re
- `get_quarantine` — GET /quarantine — rejected events for the caller's org, newest first, with violation details.
- `list_contracts` — GET /contracts — identities the API key can see.

## 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    \"mcp-server\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"@contractgate/mcp-server\"\n      ],\n      \"env\": {\n        \"CONTRACTGATE_API_KEY\": \"<YOUR_CONTRACTGATE_API_KEY>\"\n      }\n    }\n  }\n}"
```
**Credentials it will ask for** (names only — Forge never holds a value):
- `CONTRACTGATE_API_KEY` — Contractgate 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 22, ceiling 22 (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.
