Explore InfluxDB 3 schemas and query time series with the official MCP server. Choose its readonly profile for analysis without admin tools.
InfluxData’s InfluxDB 3 MCP server gives an assistant schema discovery and query tools for InfluxDB deployments. It supports database and table exploration, SQL and InfluxQL, with the available tools depending on the product and configured profile.
For an operational question, identify the database, measurement and period before calculating an average or comparing values. The query response can include a row count, truncation status and warnings. Include those details with the query so a partial response is not mistaken for the complete dataset.
Set INFLUX_MCP_TOOL_PROFILE=readonly for analysis without write, administration, token-management or host-level tools. The npm setup requires Node.js 20.11 or later and npm 9 or later. Credentials and connection variables differ across Core, Enterprise and cloud products; use the matching example configuration in the repository.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
