Overview

AI-generated overview

Infinihash KYT lets an assistant screen crypto wallets against sanctions and risk data, run pre-payment checks, and manage compliance cases and SAR drafts.

What you can do
Screen wallets against OFAC SDN and risk labels, or look up intel tags for an address without a full screen, and review recent org screenings and coverage stats or backend health. Run a pre-payment check that returns ALLOW, REVIEW or BLOCK with a signed receipt, and verify that receipt. Open, list and fetch compliance cases and append investigation notes to the audit trail. Generate a FinCEN-aligned SAR draft from a case.
When to use it
Useful for compliance, fraud or treasury workflows that need to check whether a crypto address is sanctioned or risky before a payment, or to track screening results as cases and draft SARs. Also suited to agents that must gate crypto transfers on a screening decision.
Requirements
Remote endpoint with OAuth sign-in, or a local stdio process via uvx or pip (Python). Requires a KYT API key supplied as KYT_API_KEY; a free tier of 100 screenings per month is offered. KYT_BASE_URL is only for self-hosted or staging setups. Network access to the Infinihash service.
Before you install
The API key is a secret and must be kept out of shared configs. Paid tiers exist (Starter and Pro) beyond the free allowance, so usage can incur cost. The server creates and modifies compliance cases and notes, and generates SAR drafts; it is decision support only, and the organisation remains responsible for regulatory determinations and SAR filing. Wallet addresses and screening data are sent to a third-party service.

Installation

In SourceWeft

  1. Open Infinihash Kyt Mcp in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Infinihash%2Finfinihash-kyt-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

infinihash-kyt-mcp

MCP server for Infinihash KYT — real-time blockchain transaction monitoring, sanctions screening, and SAR generation as MCP tools.

Gives any MCP-compatible agent (Claude Desktop, Cursor, Cline, automation pipelines) access to:

  • kyt_screen_wallet — screen a wallet against OFAC SDN + 18.8K+ risk labels in under 200ms
  • kyt_lookup_intel — get known intel tags for an address (no full screen)
  • kyt_recent_screenings — what your org has been screening
  • kyt_create_case — open a compliance case from a risky screening
  • kyt_list_cases — list open / SAR-pending / closed cases
  • kyt_get_case — fetch one case with evidence notes
  • kyt_add_case_note — append investigation notes to the audit trail
  • kyt_generate_sar — render a FinCEN-aligned SAR draft
  • kyt_stats — coverage stats (per-source breakdown)
  • kyt_health — backend health probe

Hosted (no install)

Connect straight from Claude.ai, Claude Desktop, or any MCP client that supports remote servers:

  • URL: https://mcp.infinihash.com/mcp. Sign in with your KYT API key when prompted (OAuth).
  • No key yet? https://mcp.infinihash.com/free/mcp gives anonymous, basic sanctions screening.
  • Claude Code: claude mcp add --transport http infinihash-kyt https://mcp.infinihash.com/mcp

The hosted server adds preflight_payment: call it before an agent sends crypto. It returns ALLOW, REVIEW or BLOCK plus an Ed25519-signed receipt you can keep for examiners (verify_receipt checks it; public key at /.well-known/kyt-receipt-key).

Install (local, stdio)

bash
uvx infinihash-kyt-mcp

Or:

bash
pip install infinihash-kyt-mcp

Example prompts after install

Screen wallet 0x722122dF12D4e14e13Ac3b6895a86e84145b6967 — is it sanctioned?
Open a case for the Tornado Cash address I just screened.
Generate a SAR draft for case <id> and email me a summary of what to include.
What labels do we have on 0x... — quick check, no full screen.

Why KYT over alternatives

  • Published pricing — no "contact sales" — Free $0, Starter $49/mo (500 screenings), Pro $199/mo (3,000 screenings)
  • Source transparency — every label tiered (T1 OFAC, T2 threat intel, T3 on-chain, T4 community) and source-attributed at /trust
  • Self-serve in minutes — API key in under a minute, no procurement cycle
  • Sub-200ms screens — fast-path cache returns sanctioned wallets in milliseconds

Compliance note

KYT is a decision-support tool, not a SAR filing service. Your organisation remains solely responsible for SAR submissions via the BSA E-Filing System and for all regulatory determinations.
