Arcadia MCP Server

Workarounds and additional tools for Cursor users on Windows.

Features

• Bash command execution

  • MCP tools: run_bash_command, read_output
  • Avoids Cursor bug: run tool attempts to use xterm bracketed paste on Windows where that isn't supported.
  • Avoids Cursor bug: run tool sometimes hangs before actually starting the command.
  • Avoids Cursor bug: commands sometimes execute but never return control to the model.
  • Improves on Cursor by automatically paging command outputs. Paging avoids blowing out the model's context from an unexpected long command output.
  • Improves on Cursor by adding mandatory timeouts to all command executions.

• Database querying and exploration

  • MCP tools: list_database_connections, list_database_schemas, list_database_objects, describe_database_object, list_database_types, run_sql_command
  • Connect to SQL Server databases and SQLite files to explore schemas, list objects, and execute queries
  • All SQL commands run in transactions that automatically roll back, ensuring no accidental data modification
  • Supports both SQL Server (with Windows or SQL authentication) and SQLite databases
  • Automatic output paging prevents long query results from overwhelming the model's context
  • Configure SQL Server connections in config.jsonc under the connections section

• Real-time log monitoring

  • logs.bat tool for viewing active command execution logs. The logs don't appear "live" inside Cursor, so use this tool in a separate terminal window to view the logs as they happen.
