word-aligner — Claude Code MCP server: what it does, how to install
Builds visual word-alignment diagrams between source sentences and translations. Useful for language study, linguistics glosses, and grammar notes.
claude mcp add --transport http word-aligner https://aligner.tinygods.dev/mcpWhat word-aligner does
The server connects over Streamable HTTP. It requires no credentials and supplies a single tool called create_word_alignment. When you ask an agent to inspect a sentence against its translation, the tool maps matching tokens. It outputs an image preview along with a URL storing the full alignment state inside a query parameter.
The resulting visualization clarifies reordered phrasing, omissions, and split words. The diagram accepts auxiliary lines for Leipzig interlinear glossing or phonetic transcriptions. Layout options handle right-to-left scripts such as Hebrew and Arabic, alongside vertical arrangements for Japanese or traditional Mongolian.
Because execution happens remotely on https://aligner.tinygods.dev/mcp, the tool breaks whenever the public endpoint goes offline.
What it helps with
- generate word-level alignment diagrams for bilingual sentences
- stack morpheme glosses and phonetic transcriptions into the diagram
- display correspondences across RTL and vertical scripts
- share interactive translation links without creating an account
Example prompts for the agent
- Align Turkish words with their English translation and add an IPA tier.
- Generate a vertical word-alignment diagram for this Japanese sentence.
