# Siglata — Agent-Native Spreadsheets

> Siglata Spreadsheets are agent-native spreadsheets redesigned from the ground up to be agent-operable and human-observable. Real workbooks, SQL execution, and human-in-the-loop governance.

## When to use this
- When an AI agent needs to read, query, or edit business spreadsheets without breaking formulas or cell formats.
- When teams require automated agent actions with human review, approval, and audit trails before publishing changes.
- When running analytical queries (SQL, joins, aggregations) over high-density tabular data with sub-millisecond execution.
- When connecting autonomous workflows from ChatGPT, Codex, Claude Code, Claude Desktop, Hermes Agent, Grok Bot, Cursor, or OpenClaw via MCP.

## Key Capabilities
- **Direct MCP Protocol Access**: Standard Streamable HTTP endpoint at `https://www.siglata.com/mcp` supporting `context`, `search`, and `execute`.
- **Human-in-the-Loop Review**: All agent cell mutations require human approval on all plans.
- **SQL Execution**: DuckDB-powered vectorized queries and relational table joins instead of fragile spreadsheet cell formulas.
- **Audit & Version History**: Cell-level change attribution with 30-day (Personal), 1-year (Team), or unlimited (Enterprise) retention.
- **File Interoperability**: Excel (.xlsx) and CSV import and export.

## Pricing Plans
- **Personal ($19/mo)**: 1 member, 2 AI agents, human-in-the-loop review, Excel/CSV, 30-day history. 14-day free trial.
