RAGFence

Security testing and authorization-aware retrieval for production RAG systems.

RAGFence is a Python library and CLI that helps teams build and verify RAG pipelines that never leak. It provides authorization-aware retrieval primitives, a deterministic evaluation engine, and the generic_http adapter for testing an external RAG target.

Status: v0.1.0 — production-ready release. The evaluation and adapter contracts are implemented and covered by offline tests. The reference database path is an optional Docker-backed check; this repository does not claim a public CI run.

Quickstart (offline)

Requires Python >= 3.12. The offline quickstart needs no Docker, PostgreSQL, network access, API keys, or other external services.

python -m venv .venv
.venv\Scripts\python -m pip install -e ".[dev]"   # Windows
# source .venv/bin/activate && pip install -e ".[dev]"   # POSIX

Check the installed CLI, initialize a local project, and run the deterministic reference evaluation:

ragfence --help
ragfence init
ragfence test

The human-readable report is written to .ragfence/reports/latest.txt and the machine-readable report is written with:

ragfence test --json

which writes .ragfence/reports/latest.json. Use --output PATH to write the report to an explicit destination. Exit codes are:

• 0 = completed evaluation meets the configured threshold (gate passed).
• 1 = completed evaluation is below the threshold (gate failed).
• 2 = configuration, usage, reachability, or runtime failure.

Run the repository quality gates without Docker or other external services:

python -m pytest
ruff check .
ruff format --check .
mypy

Optional Docker database checks

Docker Compose is optional and only needed for database-backed reference checks. It starts PostgreSQL 16 with pgvector; it is not required by the offline tests or the generic HTTP adapter tests:

docker compose up -d

Use ragfence init --up to start, migrate, seed, and embed the reference DB in one step. When installed from a wheel (outside this repository), init --up uses the reference environment bundled inside the package — no checkout required. Use ragfence adapter check reference to verify connectivity, migration state, and seed completeness against a running database.

Safe starting points for configuration are examples/reference.toml and examples/generic_http.toml. The latter uses CHANGEME and localhost placeholders only.

Production evaluation path

The production reference evaluation executes a declarative control matrix of 8 controls against the reference adapter (DB-resolved identities, RetrievalService and DbVectorStore/pgvector):

Each control result has one of four statuses: PASS, FAIL, INCONCLUSIVE, or SKIPPED. A single EvaluationGate fails closed for required failures, required inconclusive controls, missing coverage, missing identity/retrieval evidence, target errors, or threshold failure. The gate reports three scores: security_score, utility_score, and overall_score (mean of the two, computed over executed required controls only). The JSON report includes per-control results, the three scores, gate_passed, gate_reason, and outcome (exactly "pass" on healthy runs). The report declares real_provider_used: false because the production matrix path uses no external provider.

The legacy v0.1 generation-skip semantics (no_real_provider) apply only to the legacy engine path and never to the production matrix path.

External identity strategies

The generic_http adapter represents identity only through explicit configuration. Two identity strategies are supported:

• Header templates: interpolate an allowlisted set of actor placeholders ({actor_user_id}, {actor_tenant_id}, {actor_department_id}) into configured request headers.
• Bearer token: uses the auth_token configuration value (set via environment variable for secrets).

Identity-dependent controls without a configured strategy are INCONCLUSIVE and the gate fails. Secrets are redacted from reports, findings, reasons, and errors.
