Paper Club
By Paper Club
With the Paper Club MCP connector, you can search for the best media websites to get sponsored articles, add them to you cart, fill the briefs, placed your orders and be updated about their status. The search enables a wide range of parameters: depending on your objectives, you can use filters such as topics, SEO metrics (min or max of TF, DR, traffic, etc.) but also positioned keywords (source Ahrefs) and domain exact match. The MCP connector also integrates a custom user interface to display the result of searches (list of websites with their metrics and price, with an "Add to cart" button"), display your cart and your wallet balance, and (quite useful!) an editable view of the brief so you can directly modify what Claude will suggest. There is an impersonation tool: it is JWT-gated to admins and agency-admins only and scoped to accounts they already control on our platform.

PaperAgent
By CHRISTOPHE GUIDO Y SMET
PaperAgent lets Claude mail individual, one-off physical letters through the United States Postal Service. Claude validates the US recipient address, writes a private draft, and shows you a PDF preview of exactly what will be printed along with the exact total. Nothing is sent until you approve: Claude then hands you a secure Stripe payment link, and once payment completes PaperAgent prints the letter in New York and hands it to USPS. You can ask Claude where a letter is at any time. Good for cancellation notices, complaint and refund requests, landlord repair requests, security-deposit requests, and any letter that has to arrive on paper. Choose Standard First-Class mail, or Certified Mail with a USPS tracking number and a delivery record. Checking prices and validating an address work without an account; drafting and sending need you to sign in. PaperAgent is not an email, fax, bulk-mail, or legal-advice service. US domestic addresses only.

PaperOffice
By PaperOffice
Built for companies. Ready for AI agents. PaperOffice is the headless DMS for Claude. Connect your company account, and Claude works with your business documents: invoices, contracts, delivery notes, HR files, scans and phone photos. No uploads into the chat. Your documents stay in PaperOffice, and Claude works on them in place, with more than 300 tools as a complete documents operations layer. Try asking Claude: • "Which supplier invoices are due this month?" • "Find our lease agreement and tell me the last day for notice." • "Check this delivery note against the order." • "Start our approval workflow for the new invoices." • "Redact the personal data in these HR files before I share them." What Claude can do for you: • Find documents by what they say, scans included: full text, OCR, meaning and entities. • Read text and extracted fields, each value with its place in the original document. • Import and classify documents, run AI-OCR on print, tables and handwriting, manage versions. • Start workflows, send documents to human review, request e-signatures, place legal holds. • Redact personal data, translate, convert, merge and compress PDFs. • Get overviews of document volumes, due dates, finances and audit findings. • Validate VAT IDs, addresses, email addresses and phone numbers. Safe by design: Claude signs in with OAuth and acts only as you, with your existing permissions and workspace rules. Every tool is labelled as read-only, writing, or deleting and sending, so changes can require your confirmation. Signatures stay with people: Claude sends the signing request, and the signer signs on the signing page with an SMS code. Your documents are stored in PaperOffice's own EU data center or on your own NAS or server (BYOS). PaperOffice holds ISO 27001 and SOC 2 Type II. Claude provides the intelligence. PaperOffice provides the document infrastructure behind it.

PaperPorter
By Shrikar Archak
PaperPorter fills official PDF forms, such as city building permits, planning applications, business licenses, and food truck permits, without changing their layout. Ask Claude to find a reviewed form by city or name, and it reads the form's questions, collects your answers in conversation, saves them as a private draft, and validates them. Claude shows you every answer for confirmation before generating the filled PDF, and returns a download link that expires after 15 minutes. PaperPorter only uses answers you provide, never fills signatures, and never submits forms for you. Browse ready forms at paperporter.com/permits.

Paperarchive
By Paperarchive
Paperarchive is a document archive for invoices, contracts, insurance policies, bank statements and letters. It reads every document with OCR and AI, extracts amounts, due dates and senders, and turns them into events such as "invoice open until 15 March". With the Paperarchive connector, Claude can search your archive by content, read document details and extracted fields, look up bank statement transactions, list what is open or due, and give you a short-lived download link to the original file. If you allow it when connecting, Claude can also keep your archive tidy: mark an invoice as paid, confirm, archive or cancel an open item, and add or remove existing tags on a document. These permissions are off by default, each one is a separate checkbox, and every change follows the same rules as in the Paperarchive app. Uploading, deleting or reprocessing documents is never possible through the connector. You choose which Spaces the connector can see. Access ends immediately when you disconnect in Settings > Connections & API. Requires a Paperarchive account with Premium or an active trial.

Paperguide
By Keevs Health Inc.
Paperguide is an AI-native platform for scientific research and evidence synthesis. This connector brings your Paperguide reference manager and literature search into Claude. Literature search. Search 200M+ peer-reviewed papers and preprints from PubMed, arXiv, OpenAlex and Semantic Scholar, then narrow by year, citations, open access or journal quartile to build a literature review search strategy. Look up any paper by DOI or PubMed ID for its abstract, authors, journal, citations and BibTeX entry. Draft reading lists, summaries and literature review sections as cited answers, where every claim links to its source. Your reference library. Add a paper by DOI or PDF link and it lands in your Paperguide reference manager with its details filled in and the open-access PDF attached; papers you already have are never added twice. Chat with your PDFs: ask what your saved papers say about a question and Claude searches inside their full text with page numbers, or reads a whole paper to summarise it. Create and rename folders and file papers from the chat. In Paperguide itself, the same library annotates, shares, cites in 1,000+ citation styles, imports from Zotero, Mendeley, BibTeX and RIS, and opens paywalled papers through your institutional proxy. A systematic review runs end to end there: title and abstract screening, full-text screening with a dual-reviewer mode, data extraction with sentence-level evidence, and PRISMA reporting, with every screening decision logged. Research agents handle multi-step searches, and systematic review data extraction exports as a table. For PhD students writing a thesis, clinicians summarising evidence, and teams whose reviews must survive peer review or audit. Works in Claude on web, desktop, mobile and Claude Code, with a free Paperguide account. Adding and organising papers is free; searching and reading use your Paperguide credits.
