Stipple — Document Verification & Extraction

Stipple MCP server

Documents in. Answers your agents can act on.

Stipple is a hosted MCP server for document work: forensic authenticity signals, structured field extraction, Australian identity checks, adverse-media and sanctions screening, AU/NZ government tender search, AI-written-text detection, and citation verification for research reports.

No install, no signup — an anonymous free tier works immediately.

Connect

claude mcp add --transport http stipple https://www.stipple.sh/mcp

Or in any MCP client config:

{ "mcpServers": { "stipple": { "type": "http", "url": "https://www.stipple.sh/mcp" } } }

• Endpoint: https://www.stipple.sh/mcp (Streamable HTTP)
• Always the www. host — the apex domain redirects, and a POST through the redirect fails for non-browser clients.
• Auth: none required. An optional free API key (POST /v1/keys) gives a private credit allowance; send it as Authorization: Bearer stp_....

Tools (13)

Tool	What it does	What it is NOT
verify_document	Forensic authenticity inspection of a PDF/image (URL or base64): risk_band + inspection_quality + evidence	A fraud verdict — it is a signal with the evidence behind it
extract_fields	Structured fields from a document: ad-hoc field lists, templates (payslip, tax invoice, bank statement, receipt, contract), tables, per-value grounding, redaction, layout, chunking, splitting	A judgment — values are what the document shows; absences come back in not_found
verify_identity	Australian identity check over a document set: AFP 100-point or AUSTRAC safe-harbour, with exactly what is missing	A forgery check — pair with verify_document
check_pack	Does a document set satisfy a checklist (named scheme or ad-hoc requirements)?	Approval — presence of the right types, not genuineness
screen_adverse_media	Adverse media + corroboration-gated sanctions/PEP screening of a person or organisation	A determination — "review", never "guilty"; "nothing found" is not a clean record
find_tenders	Free. Search open AU/NZ government tenders	—
match_tenders	Rank open tenders against what a company's own website says it does, with why[] and gaps[]	A win probability
tender_sources	Free. Where tender data comes from, and why a search can be empty	—
detect_ai_text	Probability a document's prose is AI-written, with the linguistic tells; abstains on non-prose	Calibrated truth — and style, not authenticity
verify_references	For a report: citations resolve and match, internal arithmetic recomputes, unsupported claims flagged	A truth verdict — it reports verification coverage
check_document	Has this exact file (sha256) been inspected already? Skips a paid call	—
get_warrant	Fetch a stored result bundle (JSON or Markdown)	—
submit_feedback	Thumbs up/down on a rating	—

Guided workflows shipped with the server: Verify a document's authenticity · What kind of document is this? · Run a 100-point identity check · Screen a person for adverse media · Find tenders my company could bid for · Was this written by AI? · Fact-check a report URL · Fact-check pasted text.

How results read

Every inspection reports two independent axes: risk_band (how authentic the document looks) and inspection_quality (how completely it could be inspected). A clean phone photo of a real payslip is commonly low risk + limited quality — "nothing looks tampered, but we couldn't read everything". Low coverage is not risk.

Identical documents are cached by content hash — resubmitting the same bytes returns the stored result instantly and free.

Credits

Anonymous callers share a free weekly allowance per IP. A free API key gets its own allowance and metering. Tender search and source listing cost nothing. Details: stipple.sh/pricing.
