## MCP tools (10)

### `inspect_file` (~96 tokens)

Inspect a CSV, JSON or Excel file

Report the columns, row count and any parse warnings for a CSV, JSON or Excel file without loading the whole thing into the conversation. Use before converting so you know the shape of the data.

Input parameters:

- `format` (string): Defaults to detection from the file extension.
- `has_header` (boolean): Treat the first row as column names. Default true.
- `input_path` (string, required): Absolute path to the source file on this machine.

### `read_rows` (~189 tokens)

Read rows from a CSV, JSON or Excel file

Read a slice of rows from a tabular file, with optional search and sorting, returning them as a compact table. Use this to look at part of a large file without pulling the whole thing into the conversation: ask for the rows you need rather than reading the file directly.

Input parameters:

- `filter` (string): Case-insensitive text match across all columns.
- `format` (string): Defaults to detection from the file extension.
- `has_header` (boolean): Treat the first row as column names. Default true.
- `input_path` (string, required): Absolute path to the source file on this machine.
- `limit` (integer): Rows to return. Default 50, maximum 500.
- `offset` (integer): Rows to skip. Default 0.
- `sort_column` (string): Column name to sort by.
- `sort_direction` (string): Default asc. Empty cells always sort last.

### `csv_to_excel` (~154 tokens)

Convert CSV to Excel

Convert a CSV file on this machine to Excel and write it to disk. Returns a summary rather than the file contents, so large files do not fill the conversation. Runs locally: nothing is uploaded. Types are inferred per column, so leading zeros and formatting survive instead of being mangled.

Input parameters:

- `has_header` (boolean): Treat the first row as column names. Default true.
- `input_path` (string, required): Absolute path to the source file on this machine.
- `max_rows` (integer): Stop after this many data rows.

### `csv_to_pdf` (~197 tokens)

Convert CSV to PDF

Convert a CSV file on this machine to PDF and write it to disk. Returns a summary rather than the file contents, so large files do not fill the conversation. Runs locally: nothing is uploaded. PDF text is limited to latin-1; characters outside it become question marks and are reported. Types are inferred per column, so leading zeros and formatting survive instead of being mangled.

Input parameters:

- `has_header` (boolean): Treat the first row as column names. Default true.
- `input_path` (string, required): Absolute path to the source file on this machine.
- `max_rows` (integer): Stop after this many data rows.
