adclip

Generate ad creative from a single JSON brief. adclip is an MCP server that turns a structured brief into ad copy and static images across Meta, Google, LinkedIn, and X formats. Self-review loops filter for policy violations and score variants before export.

Runs under your Claude Code subscription with no API key — adclip shells out to the claude CLI for LLM calls, so your subscription auth is reused. Paid third-party providers (Anthropic direct, fal.ai image generation) are opt-in and gated behind ADCLIP_ALLOW_LIVE_APIS=1 so a stray key in your environment can't silently bill you.

What a run looks like

Brief in (examples/taichi_brief.json):

{
  "product": "Taichi crypto trading bot",
  "value_prop": "Paper-trade our signals before risking real cash.",
  "audience": "Skeptical retail crypto traders.",
  "angles": ["credibility", "curiosity"],
  "tone": "confident, dry, no hype",
  "cta": "Start paper trading",
  "formats": ["meta_feed_4x5", "google_rsa"],
  "variants": 2,
  "policy_profile": "crypto",
  "must_avoid": ["guaranteed returns"],
  "use_judge": true,
  "heal_violations": 2,
  "output_dir": "/tmp/adclip_out"
}

Out:

• 2 × meta_feed_4x5 composites (1080×1350, headline + body + CTA burned in)

• 2 × google_rsa text variants

• manifest.json with per-variant costs, policy flags, judge scores, and rationales

• A campaign directory ready for adclip_export_dco → direct Meta DCO upload

Install

pipx install adclip

For the optional direct-Anthropic-API provider:

pipx install "adclip[anthropic]"

Requires Python 3.11+ and the claude CLI on $PATH (for the default keyless LLM path).

From source (for contributors)

git clone https://github.com/dreliq9/adclip.git
cd adclip
python3.11 -m venv .venv
.venv/bin/pip install -e ".[dev]"

MCP usage

Add to your project's .mcp.json (or ~/.claude.json):

{
  "mcpServers": {
    "adclip": {
      "command": "adclip-mcp"
    }
  }
}

Then ask Claude: "Generate ad variants for examples/taichi_brief.json"

The three tools you'll use most

• adclip_generate_variants — full pipeline: brief → copy → policy → images → composite → render

• adclip_generate_copy — copy pool only (cheap iteration before spending on images)

• adclip_export_dco — emit Meta DCO modular components (deduped headlines/bodies/ctas + per-aspect images)

Brief + inspection

• adclip_brief_validate — schema check

• adclip_estimate_cost — LLM + fal cost estimate

• adclip_list_formats — format catalog

• adclip_policy_check — policy dry-run on arbitrary copy

• adclip_campaign_status — manifest, variants, costs, missing-file audit for a campaign dir

Generation

• adclip_generate_copy — copy pool only

• adclip_generate_visuals — given a list of winner copies, produce images + composites

• adclip_generate_variants — full pipeline

Iteration on an existing campaign

• adclip_render_variant — re-composite one variant (cheap; no LLM, no fal)

• adclip_regenerate — redo one variant's copy, visual, or both

• adclip_score_variants — re-rank variants against (possibly edited) brief; heuristic or LLM judge

• adclip_export_dco — Meta DCO modular export

CLI

adclip formats                              # list format specs
adclip estimate examples/taichi_brief.json  # cost preview
adclip copy examples/taichi_brief.json      # copy only (no images)
adclip run  examples/taichi_brief.json --image fake  # full pipeline, stub images

The CLI uses claude-cli by default — no key setup needed.

Formats

¹ Video formats produce a fal.ai-generated clip (default kling-2.6, 5s) with headline + CTA burned in via FFmpeg drawtext, scaled/padded to the format's dimensions, and (when audio is present) loudness-normalized to the format's LUFS target. Requires an ffmpeg build with the drawtext filter (i.e. compiled with freetype). Set ADCLIP_ALLOW_LIVE_APIS=1 and FAL_KEY to enable; pass --video fake (CLI) or video_provider="fake" (MCP) for tests.

LLM provider modes

Self-review loops

• Judge (use_judge: true): after policy filtering, an LLM scores each survivor on brand fit, angle fit, and copy quality; top-N by blended score wins. judge_score, judge_rationale, and judge_flags land in the manifest.

• Heal (heal_violations: N): policy-violating candidates are sent back to the LLM with the specific violations and asked to rewrite. Successful heals gain a heal_attempts count and a healed_from snapshot of the original copy.

• Semantic policy (use_semantic_policy: true): an LLM second-pass flags paraphrases that slip past the literal blocklist (e.g. "printing money" when must_avoid contains "guaranteed returns"). Feeds the same heal loop. Adds one LLM call per candidate — opt-in.

Live-API opt-in

ADCLIP_ALLOW_LIVE_APIS=1 must be set to use any paid third-party API (anthropic provider, fal.ai image + video). If a key is in your env but the gate is closed, the provider refuses with a clear error instead of billing you. Default keyless paths never need this set.

Status

v0.1 — static images, text ads, and 9:16 video ads (Reels / TikTok / Shorts) via fal.ai (declip-driven model catalog). 12 MCP tools, CLI, four LLM providers (claude-cli / sampling / anthropic / fake), Meta DCO export, self-review loops (policy + heal + semantic + judge).
