Export Data from MongoDB MCP Server

The MongoDB MCP Server export tool outputs the results of a query or aggregation pipeline to an EJSON data file.

The exported results are saved to a file on the computer that runs the MCP Server. You can also access the exported data through the exported-data resource using the AI client application.

Export Directory Path

The following table shows the default directory paths where the MCP Server temporarily stores the exported data files:

Operating System	Default Directory Path
Windows	`%LOCALAPPDATA%\mongodb\mongodb-mcp\exports`
macOS and Linux	`~/.mongodb/mongodb-mcp/exports`

To change the export directory path, set one of these:

exportsPath option in a JSON configuration file or command line
MDB_MCP_EXPORTS_PATH environment variable

To view the JSON configuration file options, see MongoDB MCP Server Configuration Options. To view JSON configuration file examples, see Get Started with the MongoDB MCP Server.

The exportTimeoutMs configuration option specifies the time after which the exported data is eligible for deletion.

The exportCleanupIntervalMs configuration option specifies the time interval between runs of the cleanup process that deletes expired export files.

For an export example, see Export Output to File.
