Each match is replaced with a `[REDACTED:type]` marker before content reaches memory units or the document body. The feature is configured per bank and disabled by default. + +## How it works + +Memory Defense is opt-in per bank. The extension is always present, but it sits dormant until you give a bank a policy that turns it on. When a policy is set, every memory the agent writes to that bank is scanned before it lands in storage. When the scanner recognizes a credential, an API key, a database connection string, or a known PII format, the matched substring is replaced with a redaction marker like `[REDACTED:github_token]`. + +The scrubbed version is what actually gets stored. Memory units and document bodies persist the redacted text, so future recall responses, exports, and reflect operations never see the original secret. + +A policy only affects future retain calls on the bank where it is set. Existing memories are not retroactively scanned when you add or change a policy. + +## Configuring Memory Defense + +Memory Defense is configured per bank via the bank's `memory_defense` config field. You can set the policy at bank creation time or update it later via `PATCH /v1/{tenant}/banks/{bank_id}/config`. + +The only rule the open-source version implements is `sensitive_data` with action `redact`. A minimal policy: + +```json +{ + "memory_defense": { + "enabled": true, + "rules": [ + { "on": "sensitive_data", "action": "redact" } + ] + } +} +``` + +Once that policy is on a bank, every retain to that bank is scrubbed with the 44 redaction patterns documented below. + +:::note Existing memories are not retroactively scanned +Enabling Memory Defense on a bank only affects future retain calls. Memories already in the bank are not re-scanned or modified when you add or change a policy. If you need to scrub a bank that already contains unredacted content, you have to re-ingest the affected memories or remove them manually. +::: + +### Disabled by default + +Memory Defense is off on every bank until you set a policy. A bank with no `memory_defense` field, with `enabled: false`, or with no `sensitive_data` rule is treated identically: the extension returns ALLOW and content passes through unchanged. To stop redacting on a bank that has it on, set `enabled: false` or remove the policy. + +## Patterns covered + +The 44 bundled patterns cover the categories below. + +### AI and LLM providers + +| Label | Catches | +|---|---| +| `anthropic_key` | `sk-ant-...` | +| `openai_key`, `openai_project_key`, `openai_admin_key` | `sk-...`, `sk-proj-...`, `sk-admin-...` | +| `google_api_key` | `AIza...` (39 chars) | +| `google_oauth_token` | `ya29.` | +| `xai_key` | `xai-...` | +| `groq_key` | `gsk_...` | +| `huggingface_token` | `hf_...` | +| `replicate_token` | `r8_...` | +| `perplexity_key` | `pplx-...` | +| `databricks_token` | `dapi` | + +### Cloud providers + +| Label | Catches | +|---|---| +| `aws_access_key` | `AKIA<16>` | +| `aws_session_token` | `ASIA<16>` | +| `digitalocean_token` | `dop_v1_` | + +### Source control and CI + +| Label | Catches | +|---|---| +| `github_fg_pat` | `github_pat_...` | +| `github_token` | `ghp_<36>` | +| `github_app_token` | `ghs_<36>` | +| `github_user_token` | `ghu_<36>` | +| `github_refresh` | `ghr_<36>` | +| `github_oauth` | `gho_<36>` | +| `gitlab_pat` | `glpat-...` | +| `npm_token` | `npm_...` | +| `pypi_token` | `pypi-AgEIcHlwaS5vcmc...` | + +### Payment processors + +| Label | Catches | +|---|---| +| `stripe_secret` | `sk_live_...`, `sk_test_...` | +| `stripe_restricted` | `rk_live_...`, `rk_test_...` | +| `square_token` | `sq0...` | +| `braintree_token` | `access_token$production$...` | + +### Communications and email + +| Label | Catches | +|---|---| +| `slack_token` | `xoxb-`, `xoxp-`, `xoxa-`, `xoxr-` | +| `slack_webhook` | `https://hooks.slack.com/services/...` | +| `twilio_api_key` | `SK` | +| `twilio_account_sid` | `AC` | +| `sendgrid_key` | `SG.<22>.<43>` | +| `mailgun_key` | `key-<32>` | +| `discord_bot` | `<23>.<6>.<27>` | +| `telegram_bot` | `<8-10 digits>:<35>` | + +### Commerce + +| Label | Catches | +|---|---| +| `shopify_token` | `shpat_` | + +### Database connection strings + +| Label | Catches | +|---|---| +| `db_url_postgres` | `postgres://user:pass@host` or `postgresql://...` | +| `db_url_mysql` | `mysql://user:pass@host` | +| `db_url_mongodb` | `mongodb://user:pass@host` or `mongodb+srv://...` | + +### Private keys, JWTs, and generic credentials + +| Label | Catches | +|---|---| +| `private_key_pem` | `-----BEGIN ...
