Questions

danbooru-tag-mcp

A Danbooru tag lookup MCP (Model Context Protocol) server for local AI image generation: your AI client resolves real Danbooru tags — exact names, aliases, categories, post counts, co-occurrence statistics, wiki descriptions, and the tag lists of real posts — before composing prompts, which noticeably improves tag accuracy in generated images.

Quick start

Install per-user (Windows 10/11, no admin rights):

iwr -useb "https://raw.githubusercontent.com/BaixuanZhu/danbooru-tag-mcp/main/install.ps1" | iex

Point your MCP client at the command:

{
  "mcpServers": {
    "danbooru-tags": {
      "command": "danbooru-tag-mcp",
      "args": []
    }
  }
}

That's it — the client picks up the seven tools below on its next session.

Features

7 MCP tools: tag search, exact tag info, related tags, alias resolution, wiki lookup, post search, and tag distribution profiles
Tag distribution profiles: get_tag_profile samples a random page of a big tag's posts and answers what it actually renders as — co-occurring tags by in-sample frequency (corpus constants like 1girl/solo split into ubiquitous), plus characteristic combinations ranked by lift, so a 300k-post tag like arm_up can be checked against what you actually wanted before it pollutes a prompt
Tag lists back from post search: search_posts returns each post's full tag list split by category (copyright/artist/character/general/meta), so mining a few posts reveals which tags naturally go together
Tagger-era tag detection: get_tag_info classifies every name against the pinned WD14 tagger vocabularies (wd14 field: live / tagger_era — a tagger-era name Danbooru has since renamed, try get_tag_alias / unknown), so LoRA card captions stop dead-ending at "tag not found"; search_tags adds wd14_hits fallback hits when no result carries posts
Uncensored by default: search_posts applies no rating filter — results reflect a tag's whole population (arm_up is ~95% g/s/q); add a rating:g/s/q/e metatag when you want only R-18 or only all-ages
Self-updating: danbooru-tag-mcp upgrade checks GitHub Releases, verifies SHA256 and replaces the binary atomically
Zero-config install: per-user installer (setup wizard or one-line PowerShell) that registers the install directory into the user PATH automatically
Polite API usage: requests are throttled to one per 1.5 seconds; anonymous access works, credentials raise the limits (free/anonymous post searches are still capped at 2 content tags per query)

Install

Requires Windows 10/11 on x64 or ARM64.

Option 1: setup wizard (recommended)

Download danbooru-tag-mcp-windows-<arch>-setup.exe from the latest release and double-click it. This installs per-user to %LOCALAPPDATA%\Programs\danbooru-tag-mcp (no admin rights needed) and registers the user PATH.

Option 2: one-line PowerShell

iwr -useb "https://raw.githubusercontent.com/BaixuanZhu/danbooru-tag-mcp/main/install.ps1" | iex

Custom install directory:

.\install.ps1 -InstallDir "D:\tools\danbooru-tag-mcp"

Option 3: portable zip

Download danbooru-tag-mcp-windows-<arch>.zip from the release page, extract danbooru-tag-mcp.exe anywhere, and run it once — the first run silently adds its own directory to the user PATH (idempotent).

Configure your MCP client

Point your MCP client (Claude Desktop, ZCode, etc.) at the command:

{
  "mcpServers": {
    "danbooru-tags": {
      "command": "danbooru-tag-mcp",
      "args": []
    }
  }
}

The bare command name works because the install directory is on the user PATH; alternatively use the full exe path.

Tools

Tool	Description	Parameters
`search_tags`	Search tags by keyword, ordered by post count; when no result has posts, adds `wd14_hits` (WD14 tagger vocab names containing the query)	`query` (required, e.g. `blue hair`), `limit` (default 10)
`get_tag_info`	Exact info for one tag (category, post count), plus a `wd14` verdict: `live` (current Danbooru), `tagger_era` (WD14 tagger vocab only, likely renamed — see `get_tag_alias`), `unknown` (neither)	`name` (required, e.g. `blue_hair`)
`get_related_tags`	Tags that co-occur with the given tag (meta-category tags like `highres` are filtered out as noise)	`tag` (required), `limit` (default 10)
`get_tag_alias`	Resolve an alias or misspelling to its canonical tag (`null` = input is already canonical)	`name` (required, e.g. `sailor_suit`)
`get_tag_wiki`	Wiki page of a tag: description, multilingual names, and the `[[tag]]` links extracted from the body	`title` or `other_names` (one required), `limit` (default 5)
`search_posts`	Search posts by a tag combination, no rating filter by default (add a `rating:g/s/q/e` metatag to narrow). Each post carries `tags` split by category: `copyright` / `artist` / `character` / `general` / `meta`	`tags` (required, space-separated), `limit` (default 5)
`get_tag_profile`	Distribution profile of one tag from a random post sample (default 200 posts, whole population — no rating filter): `co_tags` ordered by in-sample frequency, `ubiquitous` corpus constants (`freq >= 0.5`), `top_pairs` characteristic combinations ranked by lift (co-occurrence above chance). Meta tags and the tag itself excluded

CLI

danbooru-tag-mcp            run the MCP server (what MCP clients launch)
danbooru-tag-mcp upgrade    self-update via GitHub Release (SHA256 verified)
danbooru-tag-mcp version    print the version
danbooru-tag-mcp help       show help

Environment variables

DANBOORU_LOGIN — your Danbooru account name (the login you use on the site). Optional.
DANBOORU_API_KEY — your Danbooru API key, generated from the API key section of your Danbooru profile. Optional. When both DANBOORU_LOGIN and DANBOORU_API_KEY are set, every request is sent authenticated with your account (higher rate limits and content access); otherwise the client is anonymous and Danbooru applies lower limits.
DANBOORU_MCP_NO_BOOTSTRAP — skip the startup PATH registration when non-empty.

Building from source

Requires Go 1.26+ and GNU Make (bundled with Git Bash):

make test        # unit tests
make integration # online smoke test against the live Danbooru API (~1 min)
make build       # dev build -> dist/<arch>/ (bootstrap disabled)
make release     # portable zip + checksums.txt
make installer   # NSIS setup exe (requires makensis: scoop install nsis)

Releases are automated: pushing a v* tag makes GitHub Actions run the test suite and publish the setup exes, portable zips, and checksums.txt for both architectures.
