How do I install Redash?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Redash need an API key?

The publisher lists these environment variables: REDASH_URL, REDASH_API_KEY, REDASH_SAFETY_MODE, REDASH_SAFETY_DISABLE_PII, REDASH_SAFETY_DISABLE_COST.

What transport does Redash use?

Redash runs locally over stdio.

When was Redash last checked?

Last checked 2026-11-10. Connect Redash to Claude -- query data, manage dashboards, and run SQL with natural language.

Credentials from the publisher

REDASH_URL — Your Redash instance URL (e.g. https://redash.example.com)
REDASH_API_KEY — Your Redash user API key (found in Settings > Account)
REDASH_SAFETY_MODE — SQL safety mode: 'strict' blocks risky queries, 'warn' (default) returns warnings, 'off' disables guards (not recommended).
REDASH_SAFETY_DISABLE_PII — Set to 'true' to disable the PII column guard. Not recommended.
REDASH_SAFETY_DISABLE_COST — Set to 'true' to disable the query cost guard. Not recommended.

Claude Code has no install link for a local command. Copy the command below and run it in a terminal.

Questions

redash-mcp

English | 한국어 | 日本語

MCP server that connects Redash to Claude, Cursor, Gemini CLI, Codex, and any MCP client — query data, build charts and dashboards, and run SQL with natural language.

Install · Tools · Env · Examples · Troubleshooting · Privacy

What's new in 3.5

create_visualization — create line / column / area / pie / scatter charts or counters on a saved query. If the query has been run, column names are checked against its latest result, so a typo returns an error instead of an empty chart.
Dashboard auto-layout — add_widget places new widgets below existing ones; half-width widgets pair up side by side (previously they all overlapped at the top-left).

Full history: Releases

Why redash-mcp?

Built for letting an LLM touch production data safely:

🛡️ SQL Safety Guard — blocks DROP/TRUNCATE/ALTER and DELETE/UPDATE without WHERE; strict/warn/off modes, PII detection, and auto-LIMIT.
🧠 BIRD Smart Query — analyzes the question, auto-selects tables, and guides SQL generation (BIRD text-to-SQL). Optional Claude Haiku fallback.
📊 End-to-end — query, save, chart, dashboards, and alerts — 25 tools.
⚡ One-command setup — npx redash-mcp setup configures Claude Desktop / Claude Code / Cursor / Gemini CLI / Codex CLI.
🔒 Fully local — talks directly to your Redash. API key and results never leave your machine.

Installation

Requirements: Node.js 20+ and a Redash API key (Redash → Profile → Edit Profile → API Key).

npx redash-mcp setup

The wizard configures any combination of Claude Desktop, Claude Code, Cursor, Gemini CLI, and Codex CLI.

Alternatively, install Node.js, Claude Desktop, and the MCP config in one go:

curl -fsSL https://raw.githubusercontent.com/seob717/redash-mcp/main/install.sh | bash

Claude Desktop — ~/Library/Application Support/Claude/claude_desktop_config.json
Cursor — ~/.cursor/mcp.json (create it if missing)

{
  "mcpServers": {
    "redash-mcp": {
      "command": "npx",
      "args": ["-y", "redash-mcp"],
      "env": {

        "REDASH_API_KEY": "your_api_key_here"
      }
    }
  }
}

Fully quit and restart Claude Desktop after saving.

Tools

Category	Tools
Data sources & schema	`list_data_sources`, `list_tables`, `get_table_columns`
Query	`run_query` — execute SQL and return results
Saved queries	`list_queries`, `get_query`, `get_query_result` (with parameter values), `create_query`, `update_query`, `fork_query`, `archive_query`
Charts	`create_visualization` — line / column / area / pie / scatter / counter
Dashboards	`list_dashboards`, `get_dashboard`, `create_dashboard`, `add_widget` (auto-layout)
Alerts	`list_alerts`, `get_alert`, `create_alert`
Smart Query (BIRD)	`smart_query`, `get_bird_config`, `evaluate_queries`, `submit_query_feedback`, `manage_few_shot_examples`, `manage_keyword_map`

SQL Safety Guard

Applies to ad-hoc SQL run through run_query. Saved queries executed with get_query_result are not checked, so give the Redash data source a read-only DB account.

Always blocked (unless REDASH_SAFETY_MODE=off): DROP, TRUNCATE, ALTER TABLE, GRANT/REVOKE, DELETE/UPDATE without WHERE
Warned (warn) / blocked (strict): SELECT *, queries without WHERE or LIMIT, PII column access
Auto-LIMIT: appends LIMIT N when REDASH_AUTO_LIMIT is set

Details: docs/sql-safety-guard.md. Query results are also cached in memory (see REDASH_MCP_CACHE_* below).

Environment Variables

Variable	Default	Description
`REDASH_URL`	required	Redash instance URL (e.g. `https://redash.example.com`)
`REDASH_API_KEY`	required	Redash user API key
`REDASH_SAFETY_MODE`	`warn`	SQL safety level: `off` / `warn` / `strict`
`REDASH_SAFETY_DISABLE_PII`	`false`	Disable PII detection
`REDASH_SAFETY_DISABLE_COST`	`false`	Disable cost warnings
`REDASH_AUTO_LIMIT`	`0`	Auto-append `LIMIT N` to queries without one (0 = off)
`REDASH_DEFAULT_MAX_AGE`	`0`	Redash cache TTL in seconds
`REDASH_MCP_CACHE_TTL`	`300`	MCP query cache TTL in seconds (0 = off)
`REDASH_MCP_CACHE_MAX_MB`	`50`	Max memory for the MCP query cache, in MB
`REDASH_MCP_CONFIG_DIR`	`~/.redash-mcp`	Where BIRD few-shot, feedback, eval, and keyword-map data live
`REDASH_BIRD_ENABLED`	`true`	`false` disables the BIRD smart query tools
`REDASH_HTTP_TIMEOUT_SECS`	`30`	Per-request HTTP timeout against the Redash API
`ANTHROPIC_API_KEY`	—	Enables the Claude Haiku fallback for table selection in `smart_query`

Usage Examples

Just ask in natural language:

"How many new users signed up this month?" → smart_query picks the tables → run_query
"What percentage of last week's new users made a purchase?" → smart_query guides the JOIN → run_query
"Create an alert when daily signups drop below 100" → create_alert

Build a dashboard: "Save a monthly revenue query, chart it as a line, and put it on a new Revenue dashboard."

create_query — save "Monthly Revenue"
get_query_result — run it once so the chart columns can be checked
create_visualization — type: "line", x_column: "month", y_columns: ["revenue"]
create_dashboard — create "Revenue"
add_widget — place the chart; more widgets stack below or pair side by side

Troubleshooting

Symptom	Fix
`npx` not found (macOS GUI apps)	Run `which npx` and use the full path as `command`
"Authentication failed"	Check `REDASH_API_KEY` — it must be a user API key
"Unable to connect to the Redash server"	Check `REDASH_URL` (base URL with `https://`, without `/api`) and network/VPN
"The query timed out"	Simplify the query or pass a larger `timeout_secs` to `run_query` / `get_query_result`; raise `REDASH_HTTP_TIMEOUT_SECS` for slow API responses
Query blocked by the safety guard	Add `WHERE`/`LIMIT`; in `strict` mode, switch to `REDASH_SAFETY_MODE=warn` to get warnings instead
Tools don't show up	Fully restart the client after editing its config

Development

npm install
npm run dev     # run from source (tsx)
npm test        # vitest
npm run build   # typecheck + bundle to dist/

Privacy Policy

redash-mcp is a local MCP server that talks directly to your Redash instance. No intermediate servers are involved.

Item	Description
Redash API Key	Stored only as a local environment variable (`REDASH_API_KEY`). Never transmitted externally.
Query content & results	Delivered only to the local MCP client via the MCP protocol.
BIRD SQL settings	Stored only in local files (`~/.redash-mcp/`): few-shot examples, keyword maps, and feedback.
LLM Fallback	Only when `ANTHROPIC_API_KEY` is set, `smart_query` sends table names, column names, and the question text to the Anthropic API. Query results and row data are never transmitted.

We do not sell or share user data with third parties.

Retention: config files stay in ~/.redash-mcp/ until you delete them; the query cache is in-memory and cleared on shutdown; the schema cache is in-memory with a 10-minute TTL.

Contact: inquiries and security reports via GitHub Issues.
