常见问题

FileForge 安全吗？

它在 3 项适用的基础检查中通过了 3 项。我们没有阅读代码。在添加密钥或令牌之前，请先看看这个服务器要求哪些权限，并使用只具备所需权限的密钥。

它需要哪些密钥或代码？

注册中心没有列出必需的密钥，不过有些服务器会在首次使用时要求你登录。

它在我的电脑上运行还是在云端？

它在作者的云端运行。通过互联网连接，无需安装，但你发送的内容会经过作者的服务器。

它还在维护吗？

GitHub 仓库最后更新于–，最新版本（0.3.0）于4天前进入注册中心。

哪些应用可以使用它？

支持 MCP 的应用，例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接，所以接受远程 MCP 服务器的应用也可以使用，例如开启开发者模式的 ChatGPT。

有什么可以替代它？

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_DOWNLOAD_SECRET, FILEFORGE_BILLING_MODE=on,

CREEM_WEBHOOK_SECRET, CREEM_PRODUCT_STARTER_ID, CREEM_PRODUCT_PRO_ID,

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.
Results (2026-11-02, this machine)

tests/run_selftest.py - 5/5 passed:

fixtures written to .../fileforge/samples

[PASS] pdf_tables_to_excel: xlsx exists and opens - table_tables-ac3cc14d.xlsx [PASS] pdf_tables_to_excel: content matches sample table - A1='Item' B2='3' tables=1 [PASS] merge_pdfs: 2 pages, both markers present, in order - pages=2 size=1256B [PASS] images_to_pdf: 2 pages, each page embeds an image - pages=2 size=366912B [PASS] pdf_form_fill: stub raises NotImplementedError

5/5 checks passed

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).
