Rewrite a `.docx`/`.pptx` to read as human-written and score lower on AI detectors. Optionally take a detection report to rewrite only its flagged passages. Length can be held to a whole-document word range, or to per-passage ranges (experimental — limiting words weakens AI-rate reduction).
free_rehumanize
Continue a finished `humanize_document` job for **free**: upload a fresh detection report for its result and only the still-flagged passages are rewritten. Once per job, with a daily cap; the report must match that result.
fix_citations
Convert in-text citations and the reference list to APA 7, MLA 9, Harvard, Chicago, IEEE, Vancouver, GB/T 7714, AMA, ACS or OSCOLA. Body text untouched.
condense_document
Shorten a `.docx` to a target word count, keeping structure and citations.
translate_document
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Humanpen MCP is categorized under Developer Tools and uses a local stdio subprocess. In contrast, Hermes Action Bridge belongs to Developer Tools using local stdio subprocess.

Hermes Action Bridge Tools (5)
hermes_run
delegate a request to Hermes. Optional overrides: `mode`, `preset`, `contextFiles`, `yolo`, `dryRun`, and — to trade cost for speed on simple tasks — `model`, `provider`, `maxTurns`, `timeoutSeconds`. Any effective `execute` request opens an interactive confirmation form first.
hermes_plan
shortcut for `hermes_run` with `mode=plan`.
hermes_capabilities
report configured presets, skills, toolsets, runtime, and policy without inventing live integrations.
