Developers rely on Cursor Composer and terminal agents to move fast. But when agents inspect .env files or run shell diagnostics, live production keys leak to external model servers. ReclaimLLM redacts credentials locally before egress and provides enterprise audit controls.
# Developer prompt in Cursor: "Fix the database connection timeout in auth service"

The Reality of Cursor Data Ingestion
Many teams assume adding .cursorignore solves security. In practice, .cursorignore only controls what files enter the background semantic codebase index. It leaves severe gaps when developers interact with agents.

Single-command install via rclm-hooks-install. Automatically registers pre-execution hooks to redact high-entropy keys and credentials.
Route custom model endpoints through the Enterprise LLM Gateway. Developers receive team-scoped tokens; master provider keys never touch developer laptops.

Compliance control map →| Capability | Cursor Alone | Cursor + ReclaimLLM |
|---|---|---|
| .env credential redaction before egress | No (passes plaintext to LLM) | Yes (default-on hook DLP) |
| Terminal command stdout secret masking | No | Yes (command wrapper) |
| Sensitive session quarantine | No | Yes (isolated from public feeds) |
| Team-wide audit trail with file diffs | No (local history only) | Yes (centralized immutable audit) |
| Encrypted raw storage with customer recovery key | No | Yes (AES-256) |
| Zero model training guarantee | Varies by Cursor plan/privacy mode | Strict zero-training policy |
.cursorignore only excludes files from Cursor's background codebase indexing. When a developer asks Composer or Cursor Agent to debug a backend issue, test a database connection, or run a shell command, Cursor can still directly read .env files or execute commands like cat .env or printenv. ReclaimLLM intercepts tool executions locally before egress, redacting secrets before model ingestion.
ReclaimLLM uses typed redaction placeholders such as [REDACTED:API_KEY] and [REDACTED:DATABASE_URL]. Variable names and configuration schemas remain intact, allowing Cursor Composer and agent loops to debug syntax, configuration keys, and logic without ever seeing plaintext secrets.
No. ReclaimLLM's local hooks run in sub-millisecond compiled regex passes directly on developer machines. It does not route editor keystrokes through a remote CASB proxy.
When ReclaimLLM detects sensitive tokens, cloud IAM configs, or customer PII, the captured session is quarantined with a Sensitive Flag. It is excluded from team feeds, encrypted at rest with customer-held AES-256 keys, and surfaced in the CISO audit console.
Keep developer speed while satisfying security, compliance, and CISO controls.
