Idiolect AI

idiolect-mcp

Idiolect AI creates and revises writing through MCP-compatible AI tools. A Writing Profile personalizes the result using writing samples, stated preferences, and learned patterns. Writing requests do not need a brand mention or an existing profile.

Setup

Account mode

For account-resolved Writing Profile creation, loading, scoring, rewrite, and draft tools, set IDIOLECT_API_KEY:

{
  "mcpServers": {
    "idiolect": {
      "command": "npx",
      "args": ["-y", "idiolect-mcp"],
      "env": { "IDIOLECT_API_KEY": "idiolect_..." }
    }
  }
}

Slug mode

1. Get your voice at https://idiolect.app — note the slug in your result URL (idiolect.app/v/<slug>).
2. Add to your MCP config:

{
  "mcpServers": {
    "idiolect": {
      "command": "npx",
      "args": ["-y", "idiolect-mcp"],
      "env": { "IDIOLECT_SLUG": "your-slug" }
    }
  }
}

Tools

Remote OAuth and account-mode stdio advertise the same user-facing tools. Setup state, evidence approval, retries, and idempotency stay inside the server; clients receive one next action and never coordinate workflow versions or locks.

• write — drafts writing from requests, facts, notes, or outlines.
• rewrite — corrects, summarizes, expands, simplifies, paraphrases, or repurposes existing text.
• refine_writing — changes returned writing, applies a template, or records its outcome.
• view_writing_profile — lists Writing Profiles and shows the selected or current profile.
• list_writing_samples — lists the writing behind one profile.
• create_writing_profile — creates a new profile without changing another.
• add_writing_samples — adds approved writing to a selected or current profile.
• rename_writing_profile — renames a profile.
• set_current_writing_profile — makes a profile current.
• set_default_writing_template — sets or clears the default template when no profile exists.
• add_writing_rule — stores a lasting rule in the user's words.
• remove_writing_rule — stops following one stored rule.
• remove_writing_sample — revokes one ready or waiting sample.
• delete_writing_profile — deletes a selected profile.

Profile creation, approved samples, and lasting preferences can be part of writing and revision workflows. They do not require a separate profile-management request. Inferred patterns can contribute approved authored examples; they must not become user-stated rules. See the MCP content standard for writing and review rules.

Cached account-mode tool names remain callable but are not advertised. Slug mode keeps its legacy local-samples catalogue; locally configured samples are used only for stateless scoring and are not stored.

When an account has no Writing Profile, write and rewrite return the setup choices. create_writing_profile returns exact missing blocks and characters when evidence is thin. Feedback can be accepted, corrected-and-accepted, or rejected only against a succeeded server-issued output. Correction prose is retained only when the applicable consent gates permit it and within its existing expiry rule. An explicitly approved correction can be added as private V2 evidence; it never changes the current Writing Profile or silently activates V2. A stored Writing Profile is never described as provisional.

The setup response includes neither an activation token nor a capability/setup URL. create_writing_profile runs only after explicit permission from evidence you supplied or approved. Creating a profile and succeeding at a first generation are not activation. Canonical native activation occurs only after accepted or corrected-and-accepted feedback.

Credits and retries

Generation is free during beta, and completed drafts and rewrites no longer carry a credit state. The account's balance and access are shown at idiolect.app/settings. Future credits-mode states cover available, low, zero, unlimited, and temporarily unavailable balances without changing the tool names.

A known zero balance returns a structured purchase_required tool error with the stable first-party credit-management path. An accounting outage returns accounting_unavailable without a purchase suggestion. Both denials happen before generation or charging, so their retry object is explicitly scoped to pre_generation. Successful generation does not yet promise replay after a lost response, and paid enforcement remains disabled.

Internal generation coordination happens before provider work. A stale internal state is refreshed before the client receives one public retry action. If durable completion cannot be confirmed, prose is suppressed and the response uses plain language without exposing coordination receipts.

Set IDIOLECT_BASE to point at a self-hosted instance (defaults to https://idiolect.app).
