The Exact Text Diff and Patch Generator MCP server provides a high-precision engine for computing line-by-line and character-level differences between two text sequences. Using a deterministic approach, it generates unified diff formats that can be used to track changes or transform strings via the apply_patch tool. It is ideal for tasks requiring exactness, such as code reviews, automated documentation updates, or verifying content integrity. The server includes specialized tools like generate_diff for visual comparison, calculate_metrics for quantitative change analysis, and apply_patch for atomic text transformations.

3 tools expose this connector's capabilities to your AI agent.

calculate_metrics

Calculates granular metrics of text change

generate_diff

Generates a unified diff between two strings

apply_patch

The operation is atomic: it either applies perfectly or fails. Applies a unified diff patch to an original string

Generate a diff between 'Hello World' and 'Hello Universe'.

--- original +++ modified @@ -1,1 +1,1 @@ -Hello World +Hello Universe

Calculate the metrics for changing 'Apple' to 'Apples'.

The change involves 1 line addition, a character change rate of 20%, and a complexity score reflecting the single-character insertion.

Apply this patch to 'Line 1\nLine 2': '-- Line 1\n+ Line 1 Modified\nLine 2'

Line 1 Modified Line 2

The `generate_diff` tool compares an original string and a modified string to produce a unified diff format, along with insertion counts, deletion counts, and a character similarity index.
