Common questions
Is Quorum safe?
It passed 1 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed 18 days ago, and the latest version (4.0.0) reached the registry 18 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

Quorum MCP server
Give Claude, Cursor, VS Code, Windsurf, Codex or your own agent access to your databases through Quorum, with the same rules as Quorum's editor: read-only sessions, masking, and a person approving every write.

How it works
MCP (Model Context Protocol) is how AI tools call outside tools. Quorum ships an MCP server that the AI client starts on its side. The server talks to the running Quorum app over a local bridge on your computer.
- Quorum must be open. The AI client reaches your databases only while Quorum runs.
- No passwords leave Quorum. The client sends a request; Quorum runs it with its own saved login.
- Each connection is off for AI clients until you turn it on.
- Same rules as the editor: read-only sessions for reads, masking, and approval for writes.
Reads run in a read-only session and return up to 10,000 rows. Masked columns come back masked, and a query that names a masked column is refused. On DuckDB and SQLite, AI clients cannot read or write files on your computer.
Requirements
- The Quorum desktop app, version 4.0.0 or later, on macOS, Windows or Linux. Quorum is a paid product with a free 14-day trial coming soon; request access at https://www.quorumdb.ai/#access to hear first.
- An MCP client. Quorum sets up Claude Desktop, Claude Code, Cursor, VS Code, Windsurf and Codex for you, and gives you the configuration to copy for any other client.
The server runs on the Node runtime inside Quorum, so nothing else needs installing.
Set up an AI client
- In Quorum, open Settings › AI clients.
- Under 1. AI clients, find the client. Its status is Set up, Not set up, Not found, or Set up for another copy.
- Click Set up. Quorum adds its entry to the client's own configuration file and keeps everything else in it.
- Quit the client and open it again.
- Under 2. Connections the AI may use, turn on the connections it should reach.
For another client, open Another AI client: copy the config, click Copy and paste it into that client's MCP settings.
| Client | Configuration file Quorum writes (macOS) |
|---|---|
| Claude Desktop | ~/Library/Application Support/Claude/claude_desktop_config.json |
| Claude Code | ~/.claude.json |
| Cursor | ~/.cursor/mcp.json |
| VS Code | ~/Library/Application Support/Code/User/mcp.json |
| Windsurf | ~/.codeium/windsurf/mcp_config.json |
| Codex | ~/.codex/config.toml, or the folder in CODEX_HOME |
Linux uses ~/.config and Windows uses %APPDATA% for the Claude Desktop and VS Code rows.
Choose the connections AI clients may use
AI clients see no connection until you share it. In Settings › AI clients, click Choose connections…, search or browse by environment, and turn on Let AI clients use for each one.
- A shared connection is readable only while Allow AI features on this connection is on.
- Where AI may see row values is off, results reach the client as a profile of each column, not the values.
- Imported and shared connections always arrive with AI clients off.
Tools
| Tool | What it does |
|---|---|
quorum_list_connections | Lists the shared connections and how their writes are handled. |
quorum_get_schema | Reads a connection's schema: tables, views, columns, types and keys. |
quorum_describe_table | Describes one table, with the team's descriptions. |
quorum_search_schema | Finds tables and columns by name. |
quorum_sample_rows | Reads up to 100 rows of a table. Masked columns come back masked. |
quorum_explain_query | Shows the plan of a single read. EXPLAIN only, so nothing runs. |
quorum_execute_query | Runs a read in a read-only session, or a write if the write setting allows it. |
quorum_list_saved_queries | Lists the team's saved queries. |
quorum_run_saved_query | Runs a saved query as a read. |
quorum_get_query_history | Reads query history for shared connections. |
quorum_get_audit_log | Reads the write audit: who, what, risk and rows affected. |
quorum_get_data_dictionary | Reads the team's descriptions of tables and columns. |
quorum_get_service_health | Reads service health from Last9 or Datadog, when set up in Quorum. |
quorum_propose_write | Proposes a write, with a reason, for a person to approve in Quorum. |
quorum_get_proposal | Checks a proposal's outcome. |
quorum_list_proposals | Lists recent proposals and their status. |
How writes are handled
Settings › AI clients › 3. Writes from AI clients has two choices:
| Choice | What happens |
|---|---|
| Ask me in Quorum (default, recommended) | A write waits in Quorum until you approve it. On PROD it also needs PROD typed. |
| Run allowed writes directly | Allowed data changes run at once on LOCAL, DEV, QA, UAT and STAGE. Writes on PROD are refused. |
Even when writes run directly, Quorum still refuses any write on PROD and any critical write; DDL and TRUNCATE on any connection except LOCAL; writes on a connection that is read-only, always reviewed, needs a ticket or has a cool-down; and anything the safety checks block, such as an UPDATE without WHERE. Every write and every refusal is recorded in the write audit, as made by an AI agent.
Quorum Gate
With Ask me in Quorum, the AI client proposes a write with a one-line reason, and Quorum waits for you.
- Quorum shows the request: the kind, environment, connection, risk and the client's reason, then the SQL, formatted.
- What it will change shows how many rows, the columns it sets and whether any value actually changes, and a few of the matched rows with masked columns masked.
- If asked, type the confirmation word (for example PROD) and a ticket.
- Click Approve and run once, or type a reason and Reject. The client sees your reason.
An approved write runs exactly as proposed, once, through the same checks as the editor. A request expires after 30 minutes. No response means no write.
In clients that support MCP Apps, such as Claude, Claude Desktop, VS Code, Cursor and Goose, the request also appears as a card in the chat. The card shows the status; approving happens in Quorum.
The quorum command
The same bridge powers a command-line tool that runs queries through the running Quorum app and its rules. Install it from Settings › AI clients › Command-line tool.
quorum connectionsquorum query " " [--format table|csv|json] [--limit N] quorum describe [--schema S] quorum saved quorum run-saved " " [--connection C] [--format …] quorum history [--connection C] [--limit N] quorum propose " " --reason " " [--wait SECONDS] quorum request [--wait SECONDS]
Only connections shared with AI clients are reachable. Writes go through propose and wait for approval in Quorum.
