Overview

Description from the maker (original English)

File tools for your AI chat: PDF tables to Excel, merge PDFs, images to PDF, fill PDF forms.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Docs, sheets & office work

Install

Pick the AI app you use, then copy the settings.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • pdf_tables_to_excel

    Extract all tables detected in a PDF into an Excel (.xlsx) workbook, one worksheet per table. Input: the PDF file's contents as a base64-encoded string (max 25 MB, 500 pages; tables need visible ruling lines or clearly aligned columns). Returns a download_url for the .xlsx file (

Common questions

Is FileForge safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.3.0) reached the registry 4 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Agent-Native Calendar, Excel MCP Server, MCP Server for Excel

FileForge

Deterministic file processing for chat users, exposed as a remote MCP server (Streamable HTTP). Built for directory distribution (Claude Connectors Directory, Smithery, official MCP Registry, ChatGPT Apps): the host platforms bring the users; FileForge sells credit packs.

Positioning: "File tools for your AI chat" - see landing/index.html.

Architecture

Two layers, deliberately separated:

LayerFileResponsibility
Toolssrc/fileforge/tools.pyPure functions. Take local file paths, write results to output/, return a dict describing the produced file. No MCP imports - unit-testable, reusable behind a future web API. Page/pixel caps live here too (defence in depth).
Inboundsrc/fileforge/storage.py + limits.pyTurns base64 payloads from remote clients into validated, short-lived local files: strict base64, size caps (PDF 25 MB, image 15 MB), magic-byte type sniffing, PDF page cap (500), image pixel cap (40 MP), password-protected PDFs rejected.
Transportsrc/fileforge/server.pyFastMCP (streamable-http) wrapper. Tool signatures take base64 payloads; owns billing wrapper, rate limiting, per-call timeout, and the plain HTTP routes (/health, /download/ , /webhooks/creem, /v1/balance, /v1/keys).
Downloadssrc/fileforge/downloads.py + janitor.pySigned (HMAC-SHA256), expiring download tokens; expiry = file deletion time. The janitor deletes outputs after 24h (the landing page's privacy promise) and stray inputs after 1h; runnable standalone (python -m fileforge.janitor), as an in-server thread, or from a systemd timer.
Billingsrc/fileforge/billing.py + admin.pySQLite ledger. API keys (Authorization: Bearer ff_..., only hashes stored), 1 credit per call, paid credits spent first then 5 free calls/month (UTC), automatic refund when a call fails, Creem checkout.completed webhook (HMAC signature verified, idempotent by event id and order id) grants 100/300-credit packs; refund.created claws back. Admin CLI: python -m fileforge.admin create-key/balance/grant/list-accounts. Billing is OFF unless FILEFORGE_BILLING_MODE=on.

Dependencies (mature OSS only): mcp (official Python SDK, pinned >=1.2,<2 - 2.x renamed FastMCP), pymupdf, pdfplumber, openpyxl, Pillow.

Tools

ToolStatusNotes
pdf_tables_to_excel✅ implemented + self-testedpdfplumber table extraction → one xlsx sheet per table. Fails with a clear message when no ruled/aligned tables are detectable.
merge_pdfs✅ implemented + self-testedpymupdf insert_pdf, order-preserving, requires ≥ 2 inputs.
images_to_pdf✅ implemented + self-testedOne image per page, page sized to image aspect at 200 DPI; converts non-RGB inputs.
pdf_form_fill✅ implemented + self-testedpymupdf widgets. Unknown field names are rejected with the form's real field list; checkboxes accept true/false; radio groups take the option's on-state name; dropdowns validate against defined choices; optional flatten bakes values in. Registered on the server since v0.3.

All tool names are ≤ 64 characters (Claude directory requirement) and carry a human title plus a plain-language description.

Run

cd fileforge

python3 -m venv .venv .venv/bin/pip install -r requirements.txt

boot the server (endpoint: http://127.0.0.1:8765/mcp)

PYTHONPATH=src .venv/bin/python -m fileforge.server

key env: FILEFORGE_HOST, FILEFORGE_PORT, FILEFORGE_OUTPUT_DIR,

FILEFORGE_PUBLIC_BASE_URL (enables download_url in results),

FILEFORGE_ADMIN_TOKEN, FILEFORGE_JANITOR_ENABLE=1

full list in src/fileforge/server.py's docstring.

Self tests

# 1) tool-level tests: generate fixtures in samples/, call the tools,

re-open and verify the outputs

PYTHONPATH=src .venv/bin/python tests/run_selftest.py

2) transport smoke test: official MCP client against the real

Streamable HTTP app (initialize, tools/list, tools/call)

PYTHONPATH=src .venv/bin/python tests/smoke_http.py

3) remote-layer tests: storage validation, signed downloads, janitor,

billing ledger, Creem webhook (no network, throwaway DB)

PYTHONPATH=src .venv/bin/python tests/run_remote_tests.py

4) billing-on end-to-end: anon free quota, key auth, paid charge,

failure refund, signed download over HTTP, webhook credit grant

PYTHONPATH=src .venv/bin/python tests/smoke_billing_http.py

Results (2026-11-02, v0.2 remote layer)
  • tests/run_selftest.py - 5/5 passed (unchanged tool layer).
  • tests/run_remote_tests.py - 26/26 passed: base64 ingest (happy path + wrong-type/garbage/invalid/empty rejected), signed download tokens (round-trip, tamper, expiry, path traversal), janitor 24h sweep, billing (key auth, free quota exhaustion, paid-first spending, exactly-once refund, anon buckets), Creem webhook (signature verify, +100 credits, duplicate event ignored, unknown product reported not guessed).
  • tests/smoke_http.py - passed (new base64 tool signature).
  • tests/smoke_billing_http.py - 12/12 passed with billing on.

tests/smoke_http.py - passed:

tools listed over Streamable HTTP: ['images_to_pdf', 'merge_pdfs', 'pdf_tables_to_excel']

remote images_to_pdf call OK: {"file_name": "images-a66a082f.pdf", ...} [PASS] streamable-http smoke test (ASGI transport, official MCP client)

Notes on the smoke test: this dev sandbox intercepts loopback TCP between processes, so the smoke test drives the server's real ASGI app (the same Starlette app uvicorn serves) via httpx's ASGI transport - the full MCP protocol path is exercised, only raw TCP is bypassed. Standalone boot was verified separately: python -m fileforge.server starts uvicorn with "StreamableHTTP session manager started / Application startup complete".

Landing page

landing/index.html - static draft, no framework: one-line pitch, tool list, credit-pack pricing (Free 5/mo; $6 = 100 credits; $15 = 300 credits; credits never expire), contact email, and full Privacy Policy / Terms of Service sections (payment-processor review, e.g. Creem, requires a visible contact email and legal pages on the site).

TODO (next steps, in order)

  1. Deployment - public HTTPS endpoint, isolated from other workloads on the target host (dedicated user/systemd service/port/ subdomain, CPU/memory limits). Plan first, deploy after owner confirmation.
  2. Directory submission assets - reviewer test account, listing copy, icon, server.json. Claude directory additionally requires: HTTPS endpoint, tool annotations (done), and a paid Claude plan on the submitting account. Free registries first (Smithery, official MCP Registry, Glama).
  3. Known MVP trade-offs to revisit - (a) buyers claim their API key by email after purchase; add email verification before real volume. (b) Anonymous free quota is bucketed by client-IP hash; shared NATs share a bucket. (c) Claude/ChatGPT connector UIs may not let users set a Bearer header - paid users on those surfaces need OAuth later; the free tier works there today.

Done in v0.2: file ingress (base64 + limits), signed expiring download links + 24h janitor, credit/billing layer with Creem webhook, and the launch hardening set (payload caps, per-account rate limit 30/min, 120s per-call timeout, sanitised file names, page/pixel caps).
