Text File Read And Refactor MCP

Token-efficient Python stdio MCP server exposing safe text-file search, reading, and refactoring tools. Tools automatically resolve the file BOM and codepage; edit tools save files with their original encoding and BOM.

Github repository

Github repository is a curated public mirror of the project. Active development (including experimental code and private research notes) happens in a private repository; selected snapshots are published here periodically.

Installation

1. Install uv: https://docs.astral.sh/uv/getting-started/installation/

2. Configure your MCP client to run the server via uvx:

{
  "mcpServers": {
    "text-file-read-and-refactor": {
      "command": "uvx",
      "args": [
        "text-file-read-and-refactor-mcp"
      ]
    }
  }
}

Tools

Slice concept: an analog of the slice(start: integer, stop: integer) - stores the start and end indices of a range.

Boundary concept: an analog of the Boundary(text: string, type: Enum[text, word, dev_word, regex])

Span concept: an analog of the Span(left_boundary: Boundary, right_boundary: Boundary). It allows for search/replace operations such as give me the text between "my_config_param:" and ";" or replace the text between "%my_regex_1%" and "%my_regex_2%" with "my_text".

Read-only tools:

• text_file__list_allowed_directories - in pseudocode: "text_file__list_allowed_directories() -> List[directory_path]"
• text_file__file_content_length - in pseudocode: "text_file__file_content_length() -> integer_characters_num"
• text_file__read_slice - in pseudocode: "text_file__read_slice(characters_slice) -> text"
• text_file__file_lines_num - in pseudocode: "text_file__file_lines_num() -> integer_lines_num"
• text_file__read_content_by_line_range - in pseudocode: "text_file__read_content_by_line_range(lines_slice) -> text"
• text_file__find_text - in pseudocode: "text_file__find_text(text, type: Enum[text, word, dev_word]) -> characters_slice"
• text_file__expand_slice_to_lines - in pseudocode: "text_file__expand_slice_to_lines(characters_slice) -> lines_slice"
• text_file__find_span_boundaries - in pseudocode: "text_file__find_span_boundaries(left_boundary, right_boundary) -> Tuple[left_boundary_characters_slice, right_boundary_characters_slice]"
• text_file__find_span_between_boundaries - in pseudocode: "text_file__find_span_between_boundaries(left_boundary, right_boundary) -> text". Example: text_file__find_span_between_boundaries("my_config_param:", ";") will return string " my_value".
• text_file__find_span_with_boundaries - in pseudocode: "text_file__find_span_with_boundaries(left_boundary, right_boundary) -> text". Example: text_file__find_span_with_boundaries("my_config_param:", ";") will return string "my_config_param: my_value;".

Edit tools:

• text_file__replace_content_by_line_range - in pseudocode: "text_file__replace_content_by_line_range(text, lines_slice)"
• text_file__replace_slice - in pseudocode: "text_file__replace_slice(text, characters_slice)"
• text_file__replace_text - in pseudocode: "text_file__replace_slice(old_text, new_text)"
• text_file__replace_span_between_boundaries - in pseudocode: "text_file__replace_span_between_boundaries(text, left_boundary, right_boundary)".
• text_file__replace_span_with_boundaries - in pseudocode: "text_file__replace_span_with_boundaries(text, left_boundary, right_boundary)".
• text_file__patch_spans_by_boundary_patterns - in pseudocode: "text_file__patch_spans_by_boundary_patterns(List[Tuple[text, left_boundary, right_boundary]])".
