🦉 Super MCP OCR for DeepSeek (teks-only LLM)

Memberi "mata" ke model AI yang tidak punya vision (mis. DeepSeek v4 Flash, DeepSeek R1, atau LLM teks-only lain) — semua gambar & dokumen dibaca jadi teks murni yang bisa langsung dianalisa.

✨ Fitur

Format Cara baca
🖼️ Gambar — png, jpg/jpeg, webp, bmp, gif, tif/tiff OCR (RapidOCR + pre-process)
📄 PDF teks asli diekstrak; halaman scan otomatis di-OCR per halaman (max 25 hal)
📝 Office — docx, xlsx/xlsm, pptx, rtf ekstrak paragraf, tabel, slide
📃 Teks — txt, md, csv, json, xml, log, yaml, toml, html baca langsung

Tidak didukung: .doc / .xls versi lama → simpan ulang sebagai .docx / .xlsx.

Tool yang tersedia:

  • read_document(file_path, mode, enhance) — nama penuh (teks)
  • ocr_image(image_path, mode, enhance) — alias kompatibel (teks)
  • read_colors(file_path, top_n=8, merge=true) — 🎨 ekstrak warna dominan dari gambar

🎨 Baca Warna dari Gambar (read_colors)

Model teks-only juga tidak bisa melihat warna. read_colors terjemahkan warna gambar jadi teks berstruktur — hex, rgb, nama, shade, persentase area, dan posisi region. Cocok buat: copy-paste screenshot halaman web, mau ganti warna desain, cari nilai hex yang dipakai.

read_colors(file_path="web-design.png")
read_colors(file_path="ui.png", top_n=12)        # lebih banyak warna
read_colors(file_path="ui.png", merge=false)     # tanpa gabung shade dekat
Param Nilai Fungsi
file_path path gambar lokal / URL wajib
top_n 8 (default) jumlah warna teratas
merge true (default) gabung warna nyaris-sama (<30 delta)

Contoh output:

[COLORS] web-design.png — 1280x800px — top 6 warna dominan
1. #FFFFFF  rgb(255, 255, 255)  ~white (light)  53.1%  posisi: background
2. #1F2937  rgb(31, 41, 55)  ~custom (dark)  19.8%  posisi: header/navbar
3. #3B82F6  rgb(59, 130, 246)  ~custom (dark)  6.5%  posisi: accent/panel

Region label: background, header/navbar, footer, sidebar, panel/card, accent/button/text, band. Nilai hex sudah siap tempel ke CSS/Tailwind. Warna tanpa nama umum (Tailwind dll) dilabel ~custom — pakai hex/rgb-nya.

Flow copas web: gambar di-paste di chat → extract-pasted-image.py → read_colors(...) → dapat hex → edit warna.


🎯 Kenapa ini penting?

Banyak LLM yang murah/cepat hanya teks-only — mereka menolak gambar (Cannot read image / model does not support image input). Padahal pengguna sering paste screenshot error, stack trace, scan dokumen, proposal PDF.

Skill ini menjembatani: file → OCR → teks → LLM, tanpa perlu model vision yang mahal.


🚀 Cara Setup

1. Install dependensi

cd mcp-ocr
# pakai uv (disarankan)
uv sync

# atau pakai pip langsung
pip install -r pyproject.toml

Butuh Python 3.10 – 3.13. Dependensi utama: mcp, rapidocr-onnxruntime, Pillow, numpy, pypdfium2, python-docx, openpyxl, python-pptx, striprtf.

Model OCR RapidOCR (ONNX) di-download otomatis saat pertama kali dipakai.

2. Daftarkan sebagai MCP server

Tambahkan ke config MCP klien kamu (opencode, Claude Code, dst):

{
  "mcpServers": {
    "ocr": {
      "command": "python",
      "args": ["/path/ke/server.py"],
      "env": { "PYTHONIOENCODING": "utf-8" }
    }
  }
}

3. Selftest (tanpa MCP)

python server.py --selftest                    # buat sample gambar lalu OCR
python server.py --selftest "folder/file"      # test file atau folder

📖 Cara Pakai

Panggil tool dari LLM:

read_document(file_path="C:/Users/.../test-failed-1.png")
read_document(file_path="proposal.pdf")
read_document(file_path="laporan-bug.docx", mode="text", enhance=true)
Param Nilai Fungsi
file_path path lokal / URL http(s) / file:// wajib
mode auto | text | code urutan baris OCR (code terbaik utk stack trace)
enhance true (default) autocontrast + upscale teks kecil

Hasilnya teks murni + metadata singkat, contoh:

[OCR] pasted-XXXX.png — 1658x605px — 21 baris — avg confidence 0.98 — 18.5s
----------------------------------------------------
Models
# Model Provider Source Input Output ...
1 cx/gpt-5.5 9router Codex 16.5M 685K ...

🔗 Bonus: Baca gambar yang DI-PASTE langsung di chat

Ada satu masalah unik di opencode: gambar yang di-paste di kolom chat tidak disimpan sebagai file — opencode menyimpannya di database SQLite (opencode.db, tabel part) sebagai base64 data-URL. Model teks-only tidak bisa melihat bytes-nya.

Helper extract-pasted-image.py menjembatani ini:

User paste gambar di chat
        │
        ▼
[extract-pasted-image.py]  ──►  ambil gambar terbaru dari opencode.db
        │                          (base64 → file temp)
        ▼
[read_document]  ──►  OCR  ──►  teks  ──►  LLM jawab

Pakai

python extract-pasted-image.py
# → {"paths": ["C:/.../pasted-XXXX.png"], "count": 1}

Lalu OCR hasilnya:

read_document(file_path="C:/.../pasted-XXXX.png")

Opsi:

Flag Fungsi
--n <N> ekstrak N gambar terakhir (default 1)
--session <id> filter session tertentu
--outdir <dir> folder output (default temp)
--db <path> lokasi opencode.db (auto-detect)

Butuh Python + stdlib saja (sqlite3, base64, json). Lokasi DB auto-detect dari ~/.local/share/opencode/ lalu ~/.config/opencode/.

Alur kerja agent (otomatis)

  1. User paste gambar → model dapat error Cannot read image.
  2. Agent jalankan extract-pasted-image.py → ambil file temp.
  3. Agent panggil read_document(file_path=<hasil>) → teks.
  4. Agent analisa & jawab. Tanpa minta user simpan manual.

🧠 Alur Kerja Teknis (server.py)

  1. _resolve_path — terima path lokal / URL http(s) / file:// → file lokal.
  2. Routing per ekstensi — gambar → OCR; pdf → ekstrak+OCR; office → ekstrak; teks → baca.
  3. _ocr_pil (gambar) — pre-process (grayscale + autocontrast + upscale teks kecil) → RapidOCR ONNX → susun hasil jadi baris visual (urut y lalu x).
  4. _extract_palette / _read_colors (gambar) — flatten RGBA→RGB → downscale → kuantisasi median-cut (PIL) → cluster warna dominan → gabung shade dekat → hitung % area + region.
  5. Confidence filter — buang hasil OCR dengan skor < 0.35.
  6. Output — header metadata + teks murni, siap dianalisa LLM.

Kenapa preprocessing?

  • Teks kecil (< 900px) di-upscale 2–3× agar OCR akurat.
  • Gambar raksasa (> 3200px) di-cap agar tidak boros memory.
  • Autocontrast meningkatkan kontras teks di screenshot gelap/terang.

🔧 Troubleshooting

Masalah Solusi
API Error 500 max instances / 401 Insufficient balance Masalah kuota gateway model, bukan MCP OCR. Top up saldo, lalu ulangi.
Tool tidak muncul di klien Restart sesi / mcp reconnect. Cek claude mcp get ocr → harus Connected.
OCR hasil jelek Pakai mode="code" untuk stack trace; cek file dinaikkan resolusi.
.doc/.xls tidak terbaca Simpan ulang sebagai .docx/.xlsx.

📄 Lisensi
