Insyte

Ask your database questions in natural language — locally, and safely.

Insyte connects to your database with read-only credentials and turns natural-language questions into safe analytics. Ask "what were total sales last month?" or "revenue by city" from a browser workspace, a terminal UI, or your own AI tool (Claude Code / Codex) — Insyte writes the SQL, runs it read-only, and shows the answer.

Two things are always true:

1. AI models never see your database credentials.
2. Nothing can bypass Insyte's SQL validation, row limits, PII masking, or audit log — a dangerous query is rejected, not executed.

What you can do

• Ask in natural language — "total order value last month", "orders by payment method", "monthly revenue trend", "what's the expected revenue this year?"
• Three ways to use it — a browser workspace (insyte studio), a terminal UI (insyte chat), or directly from Claude Code / Codex over MCP.
• Trends, breakdowns, opportunity segments, comparisons, and forecasts over metrics Insyte generates from your schema — with charts, tables, and the exact SQL on demand.
• Investigation Mode Lite — ask broader questions like "why did total amount change?" and Studio runs a safe, multi-step investigation: trend, current-vs-previous comparison, segment breakdown, freshness checks, and next questions.
• Detailed reports (opt-in) — flip on "Detailed report" in Studio for an in-depth analyst write-up: executive summary, key insights, data-quality flags, root-cause reasoning, evidence/counter-evidence, best/expected/worst forecast, and prioritized recommendations, in a visual dashboard. Investigation questions can use the same analyst report skill over the grounded investigation bundle. See the privacy note below for what this shares.
• Interactive charts — charts include hover tooltips, readable date labels, expandable fullscreen views, and smooth trend lines for faster inspection.
• Conversation context — Studio remembers compact metric, dimension, period, and result context so follow-up questions like "same metric last month" resolve more reliably.
• Read-only and private — everything runs on your machine against your database; the raw connection URL never leaves your computer.

Detailed reports & your privacy

Everything above keeps your data on your machine. The one opt-in exception is the Detailed report: to write analyst commentary, Insyte sends the already-aggregated, PII-masked result of your query, or a grounded investigation bundle built from those aggregate results, to your local claude/codex CLI, which forwards it to that provider. The AI only writes prose — it never sees credentials, never authors SQL, and every chart is built by Insyte from real numbers. It's off by default, shows a one-time notice the first time you enable it, and can be turned off entirely with ai.detailed_reports: false in config.yaml.

Install & set up

Easiest — pipx installs Insyte in its own isolated environment (no virtual-env to manage):

pipx install insyte
insyte init          # asks for your read-only DB URL and which AI tool, then sets everything up

_{No pipx yet? brew install pipx (macOS) or python -m pip install --user pipx && pipx ensurepath, then reopen your terminal.}

Prefer plain pip? Install into a virtual environment:

python -m venv .venv && source .venv/bin/activate
pip install insyte
insyte init

insyte init walks you through it:

1. Enter your read-only database URL (stored once in a 0600 file — never in config, never logged, never sent to an AI).
2. Pick your AI tool — Claude Code, Codex, or none.
3. Insyte then connects, scans the schema, generates metrics, and wires up your AI tool — no scripts, no environment variables.

Then use it:

insyte studio        # browser workspace at http://127.0.0.1:3838
insyte chat          # terminal UI
insyte analyze total_amount --by city

Requirements: Python 3.11+, a PostgreSQL database, and — for natural-language questions — the claude or codex CLI (Studio also answers metric questions without one).

Recommended: a read-only database user

Insyte enforces read-only regardless, but a dedicated account is safest:

CREATE ROLE insyte_reader LOGIN PASSWORD '…';
GRANT CONNECT ON DATABASE your_db TO insyte_reader;
GRANT USAGE ON SCHEMA public TO insyte_reader;
GRANT SELECT ON ALL TABLES IN SCHEMA public TO insyte_reader;

Use it from Claude Code / Codex

insyte init already installs the Insyte MCP server into your chosen tool. Restart it, then ask questions in plain language — Claude/Codex call Insyte's safe tools; it validates, runs read-only, masks PII, and audits every query. (Re-run any time with insyte mcp install claude or insyte mcp install codex.)

Handy commands

Everything lives under ~/.insyte/projects/<name>/ (config, stored URL, scanned schema, metrics). The connection URL is read only when needed and never written to config.yaml.
