Overview

This MCP server provides an interface to Ledger CLI, enabling LLMs to analyze financial data, generate reports, and perform accounting tasks via command-line interactions.

This server is relatively safe for read-only operations and basic reporting. However, the ledger_raw_command tool introduces significant risk and should be used with extreme caution. Ensure the server is only accessible to trusted clients and carefully review all commands before execution.

Performance depends on the size of the Ledger file and the complexity of the queries. Large files and complex queries may take longer to process.

Cost is primarily related to the computational resources used to run the server. There are no external API costs associated with this server.

Known Risks

!Potential for command injection if input validation is insufficient.
!Exposure of sensitive financial data if the Ledger file is not properly secured.
!Unintended consequences from executing arbitrary Ledger CLI commands via `ledger_raw_command`.
!Lack of authentication makes it vulnerable to unauthorized access if exposed to a network.

Safety Score

55

moderate risk

This server is relatively safe for read-only operations and basic reporting. However, the `ledger_raw_command` tool introduces significant risk and should be used with extreme caution. Ensure the server is only accessible to trusted clients and carefully review all commands before execution.

Positive

+Ledger CLI itself provides some level of data integrity through its double-entry accounting system.
+The server requires a valid Ledger file, limiting access to only that file.
+Basic validation is included to prevent command injection.
+Access to the ledger file is limited to the path specified in the configuration.

Risks

-The `ledger_raw_command` tool allows execution of arbitrary Ledger CLI commands, posing a risk if not carefully controlled.
-Improperly configured file paths could expose sensitive financial data.
-The server relies on the security of the underlying Ledger CLI tool.
-Lack of built-in authentication mechanisms means it should only be used with trusted clients.
