Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00779 | $0.00779 |
| Opus 5 | $0.00390 | $0.00390 |
| Sonnet 5 | $0.00156 | $0.00156 |
| Haiku 4.5 | $0.00078 | $0.00078 |
Grade B, and why
metabase-flightsql-driver CLAUDE.md scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Reads MCP configurationmediumAgent snooping
mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.
`.mcp.json` runs a Metabase MCP server (`@imlewc/metabase-server`) against the local stack — export `METABASE_API_KEY` from `.env` first. The bundled official MCP server (`/api/metabase-mcp`, OAuth) suits interactive exp How it starts
The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — Metabase Arrow Flight SQL Driver
Clojure Metabase driver (:arrow-flight-sql, parent :sql-jdbc) over the Apache Arrow Flight SQL JDBC driver. Demo backends: GizmoSQL (DuckDB) and Spice.ai OSS; the same driver reaches Dremio, InfluxDB 3, Doris, StarRocks, and any other Flight SQL server.
Skills (read these before working in their area)
- driver-dev — editing
src/or the plugin manifest: build paths, rebuild cycle, pooling/connection-options invariants, auth-mode mapping, known failure signatures. - metabase-api — scripting/validating Metabase via REST or MCP: API keys, field filters with aliases, dashboard parameters.
Commands
/e2e-test— full clean-slate end-to-end test (compose up → setup script → assertions)./rebuild-driver— rebuild the driver jar and restart Metabase after a code change./upgrade-metabase <ref>— bump the Metabase pin (compose + CI matrix) with the driver-changelog checklist.
Layout
src/metabase/driver/arrow_flight_sql.clj # the whole driver
resources/metabase-plugin.yaml # manifest: auth-method dropdown, secrets, schema-filters
scripts/metabase_setup.py # e2e: admin, API key -> .env, connections, 32-card dashboard
docker-compose.yaml # metabase + postgres + spiced + gizmosql + builder
gizmosql/init.sql # 3 catalogs (memory/warehouse/staging), sales/hr/analytics
spice/spicepod.yaml # Spice v2 pod, api-key auth
.github/workflows/build.yaml # lint + matrix build {v0.62.5, v0.63.1} + manual release
Build truth
Two build paths produce different artifacts — see the driver-dev skill. Compose uses the builder (lein) jar and compile errors only appear in podman logs metabase at plugin load; CI/releases use bin/build-driver.sh inside a Metabase checkout.
Everyday commands
podman compose up -d # start everything
python scripts/metabase_setup.py # setup + test dashboard; writes .env
podman logs metabase 2>&1 | tail -100
podman logs metabase 2>&1 | grep -i "hash.*changed\|connections:" # pool health
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

metabase-flightsql-driver CLAUDE.md is an instructions file published in the GitHub repository J0hnG4lt/metabase-flightsql-driver (11 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 779 tokens to every session, about $0.0039 per session on Opus 5. A static security scan graded it B with 1 finding (reads mcp configuration). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
