# qonto-assistant

Policy-governed Qonto domain API and MCP assistant for Binky (and later
multi-tenant dogfood).

**One choke point for bank access across every coding agent and harness.**
Clients never hold the Qonto API key. v1 policy: **read for awareness only —
no spend, no volume-cost actions.**

## Status

Phase 1 runtime is implemented:

- Python 3.12 service under `src/qonto_assistant/`
- default-deny YAML policy
- Qonto read-only client (`organization`, `transactions`)
- REST endpoints: `/v1/health`, `/v1/accounts`, `/v1/transactions`, `/v1/snapshot`
- audit metadata, rate limiting, concurrency bounds, tests

Phase 2 (MCP surface, `workplans/QONTO-WP-0003-mcp-surface.md`) is in
progress: a streamable-HTTP MCP adapter is mounted at `/mcp` on the same
capability core and policy kernel as REST, with tools `qonto_org_summary`,
`qonto_list_transactions`, and `qonto_cost_run_rate_hints`. The endpoint is
gated by a shared-secret bearer token (`QONTO_ASSISTANT_MCP_TOKEN`) — see
`docs/mcp-integration.md` for the auth model, its gap vs. the OIDC/workload
target, and the shared multi-harness client config snippet. The
`finance-qonto-read` tool profile is not yet implemented.

Current verification:

- `PYTHONPATH=src ../state-hub/.venv/bin/python -m pytest` → `16 passed`
- `python3 -m compileall src tests scripts`
- `../state-hub/.venv/bin/python scripts/smoke_rest_api.py --python ../state-hub/.venv/bin/python`

Local fixture-backed smoke mode is available through `QONTO_FIXTURE_DIR`, so the
service can be exercised without real Qonto credentials. The smoke path checks
both a `31`-day recent snapshot and a `90`-day recurring-cost snapshot.

Normal local workflow, when toolchain support exists:

```bash
make install-dev
make test
make run
```
