Humanpen tools (8)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • check_job

    Look up a job by id, and download its result if it has finished. Use this after a tool returned before the job was done.

  • condense_document

    Shorten a .docx to a target word count, keeping meaning, structure and citations. Saves the result next to the source and returns its path. COSTS CREDITS at 20 per 1,000 words processed (10 minimum) - say so and get agreement first.

  • fix_citations

    Rewrite a .docx's in-text citations and reference list into one target style, leaving the body text alone. Saves the result next to the source and returns its path. COSTS CREDITS at 5 per 1,000 words processed (10 minimum) - say so and get agreement first.

  • free_rehumanize

    Continue a finished humanize job for FREE. Upload a fresh detection report for that job's result; only the passages it still flags are rewritten, at no credit cost. The server enforces strict limits: one free continuation per job, a per-day cap, the report must be of THAT job's own result (>=90% match) and show >=20% AI, and the result must still exist (kept ~7 days). If a limit is not met it retu

  • get_credit_balance

    How many credits the account has. Per 1,000 words processed: humanize 100 credits, citation fixes 5, condensing 20, translation 10, with a 10-credit minimum per job. Worth checking before a large document.

  • humanize_document

    Rewrite a .docx or .pptx so it reads as human-written and scores lower on AI detectors, keeping meaning, citations, tables and layout. Optionally pass a Turnitin/iThenticate AI report to rewrite only the passages it flagged. If a fresh report still flags the result, run this tool again on the rewritten file with that new report - only the still-flagged passages are touched, and balanced remains th

  • read_detection_report

    Read a Turnitin or iThenticate AI Writing report PDF: returns the overall AI percentage and the flagged passages. Free - reads the file without starting a job. Pass the same report to humanize_document to rewrite only what was flagged.

  • translate_document

    Translate a document into another language while keeping its layout, tables, images and formulas. Takes .docx, .pdf, .pptx, .xlsx, .epub, .html and .txt. Saves the result next to the source and returns its path. COSTS CREDITS at 10 per 1,000 words processed (10 minimum) - say so and get agreement first.

Install Humanpen in Claude Code, Cursor or VS Code

Runs npx -y humanpen-mcp on your machine. Read the scan report first; the gateway never runs local packages.

Humanize what's flagged. Preserve the rest. An MCP server for HumanPen — a document-level AI humanizer that can humanize an entire document, rewrite user-selected passages, or automatically target flagged text from a Turnitin / iThenticate AI-detection report, editing .docx / .pptx files in place while preserving formatting, tables, images, citations, and formulas. Also converts citations between 12 styles, condenses to a word budget, and translates between 12 languages.

claude mcp add humanpen -s user -e HUMANPEN_API_KEY=hp_your_key -- npx -y humanpen-mcp

Features

  • Selective rewriting by detection report — import a Turnitin / iThenticate AI Writing Report to pinpoint flagged passages; unflagged content is never touched
  • Format in, format out — a DOCX comes back as a DOCX, a PPTX as a PPTX; formatting, tables, images, and formulas survive intact and the result is still editable
  • Academic structure preserved — in-text citations, reference lists, footnotes, TOC fields, cross-references, figure numbering, equations, and special formatting are treated as protected objects
  • No error injection — restructures meaning and syntax to change expression; never adds grammar mistakes, spelling errors, or awkward sentences as a detection strategy
  • Full-length documents — no per-input word limit; a single file can be up to 100 MB, no splitting into text boxes
  • Free to keep going — still flagged? Re-humanize for free with a fresh report until the AI rate falls to * or 0%
  • Word-count control (experimental) — set a min/max word range to keep the output within a target length
  • Pay per rewrite — billed on words actually changed, not the whole document; failed and cancelled jobs cost nothing; credits never expire

Sign up at and create a key at . New accounts start with free credits, enough to put a document through and see what comes back.

The key goes in an environment variable, never in a URL. URLs end up in server logs, proxy logs, shell history and screenshots.

Install

Claude Code

claude mcp add humanpen -s user -e HUMANPEN_API_KEY=hp_your_key -- npx -y humanpen-mcp

-s user puts it in every project. The default scope is local, which loads the server only in the directory you ran the command from — and looks like a broken install the first time you open Claude Code somewhere else.

If your version rejects -e (reported upstream), use the JSON form:

claude mcp add-json humanpen -s user '{"command":"npx","args":["-y","humanpen-mcp"],"env":{"HUMANPEN_API_KEY":"hp_your_key"}}'

OpenAI Codex

In ~/.codex/config.toml:

[mcp_servers.humanpen]
command = "npx"
args = ["-y", "humanpen-mcp"]
env = { HUMANPEN_API_KEY = "hp_your_key" }

CodeBuddy / WorkBuddy

codebuddy mcp add --scope user humanpen -- npx -y humanpen-mcp

It also reads ${VAR} in its config, so the key can stay in your environment instead of the file:
