MCP-Grep

Feature: Grep Tool Functionality As Claude (an LLM using MCP) I want to search files for patterns through grep So I can find and analyze relevant information Scenario: Finding matches in a file Given I'm connected to the MCP grep server And a file with content "Line one has apple\nLine two has banana\nLine three has orange" When I invoke the grep tool with pattern "apple" and the file path Then I should receive results with 1 matching line And the result should include line number 1 And the result should contain "apple" Scenario: Case-insensitive search Given I'm connected to the MCP grep server And a file with content "Line one has Apple\nLine two has APPLE\nLine three has apple" When I invoke the grep tool with pattern "apple" and ignore_case=True Then I should receive results with 3 matching lines Scenario: Search with context Given I'm connected to the MCP grep server And a file with content "Line one\nLine two has banana\nLine three\nLine four\nLine five has banana\nLine six" When I invoke the grep tool with pattern "banana" and before_context=1 and after_context=1 Then I should receive results with 2 matching lines And each match should include context lines Scenario: Fixed string search Given I'm connected to the MCP grep server And a file with content "Line with a dot.\nLine with a [regex]" When I invoke the grep tool with pattern "." and fixed_strings=True Then I should receive results with 1 matching line And the result should contain "dot." Scenario: Recursive directory search Given I'm connected to the MCP grep server And a directory with multiple files containing the word "secret" When I invoke the grep tool with pattern "secret" and recursive=True Then I should receive results from multiple files Scenario: Limiting result count Given I'm connected to the MCP grep server And a file with content "match\nmatch\nmatch\nmatch\nmatch" When I invoke the grep tool with pattern "match" and max_count=3 Then I should receive results with no more than 3 matching lines Scenario: Regular expression search Given I'm connected to the MCP grep server And a file with content "apple123\nbanana456\napple789\norange101112" When I invoke the grep tool with pattern "apple\d+" and regexp=True Then I should receive results with 2 matching lines And the results should contain "apple123" and "apple789" Scenario: Inverted match search Given I'm connected to the MCP grep server And a file with content "apple\nbanana\norange\ngrape" When I invoke the grep tool with pattern "apple" and invert_match=True Then I should receive results with 3 matching lines And the results should contain "banana", "orange", and "grape" Scenario: Controlling line number display Given I'm connected to the MCP grep server And a file with content "Line one\nLine two\nLine three" When I invoke the grep tool with pattern "two" and line_number=False Then I should receive results with 1 matching line And the result should not include line numbers Scenario: Multiple file pattern support Given I'm connected to the MCP grep server And multiple files with extensions ".txt" and ".log" When I invoke the grep tool with pattern "error" and file_pattern="*.log" Then I should receive results only from log files Scenario: Variable context line control Given I'm connected to the MCP grep server And a file with content "Line 1\nLine 2\nLine 3\nLine 4\nLine with match\nLine 6\nLine 7\nLine 8\nLine 9" When I invoke the grep tool with pattern "match" and context=3 Then I should receive results with 1 matching line And the result should include 3 lines before and 3 lines after the match
