Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

fix
fix_duplicates
Remove duplicate adjacent words (case-insensitive, including across line breaks) and return the cleaned text plus the list of words that were removed. Read-only with no side effects: the fix is returned in the response, nothing is written anywhere. Use after check_text reports duplicate words; other issue types are report-only and have no auto-fix.
text
check_text
Analyze text for writing style issues: weasel words, passive voice, duplicate words, long sentences, nominalizations, hedging, filler adverbs, and research-cited AI tells. Read-only and stateless — text is analyzed in memory on the hosted server and never stored. Returns a plain-text report with each issue's line and column, the matched text, surrounding context, and the reason for AI tells; texts over 100,000 characters return an error message. This hosted server has no filesystem access — the wsc-mcp npm package adds a check_file tool for local files. It only reports issues — to auto-remove duplicate words, follow up with fix_duplicates.
word
list_word_lists
Return every detector word/phrase list with its entry count, config key, and sample entries, plus a link to the full browsable library. Read-only, takes no parameters, and returns the same catalog for a given release. Use it to see what the detectors match before tuning a config for check_text; not needed for ordinary checking.

Writing Style Checker — questions

Answers built from our own checks of this server.

What can Writing Style Checker do?
It exposes 3 tools, read directly from the server on our last check. Among them: check_text, fix_duplicates, list_word_lists. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Writing Style Checker working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 136 ms. The bar chart above shows every period we have measured.
How do I connect Writing Style Checker?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Writing Style Checker need an API key?
No. Writing Style Checker completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Writing Style Checker?
It answers our handshake in 136 ms on average, which is faster than 76% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Writing Style Checker?
The npm package wsc-mcp was installed 48 times in the last week. Week over week that is -43%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Writing Style Checker open source?
Yes — it is published under the MIT licence, written in TypeScript and 4 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
