Arkham blockchain intelligence: entities, labels, balances, transfers, tokens and Polymarket.

Overview

AI-generated overview

Arkham's hosted MCP server gives an assistant blockchain intelligence: entity attribution, balances, transfers, tokens, risk scores and Polymarket data.

What you can do
  • Look up addresses and entities: intelligence, balances, flows, history and risk scores
  • Trace transfers, transactions, swaps and networks, and set up live transfer streams
  • Research tokens: prices, holders, flows and trending
  • Explore Polymarket markets, positions, wallets and leaderboards
  • Check Hyperliquid (HyperCore) positions, balances and trades
  • Manage your own alerts, labels and private entities, plus intelligence feeds and account usage
When to use it
Useful when you want an assistant to answer questions about who is behind a wallet, how funds moved, or what an entity holds across 16 chains, and to combine that with token, Polymarket or Hyperliquid research without writing API calls yourself.
Requirements
Remote hosted endpoint; nothing to install. Requires an Arkham account and an API plan or trial. Sign in via OAuth, or send an API key in the Authorization header as a Bearer token. Tool calls consume API credits.
Before you install
Every tool call spends API credits from your Arkham plan, so costs add up with heavy use. The server forwards tool arguments and your key to Arkham's API. Tools write to your own alerts, labels and private entities, though none move funds or place trades. Responses are capped at 4 MiB, so large exports need the REST API.

Installation

In SourceWeft

  1. Open Arkham 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/com.arkm%2Fmcp/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.

Arkham MCP server

Arkham's official MCP server connects Claude, ChatGPT, Cursor, VS Code, Gemini CLI and other MCP clients to Arkham's blockchain intelligence. Arkham hosts it at https://mcp.arkm.com/mcp, so there is nothing to install or run. This repository holds only the manifests that MCP directories and client plugin galleries read; the server itself isn't open source.

Ask who is behind any wallet, how money moved, and what an entity holds. Arkham attributes on-chain activity to real-world entities (exchanges, funds, market makers, individuals) across 16 chains, including Ethereum, Bitcoin, Solana, Tron and Base. The server's 142 tools cover:

AreaTools
Polymarket: markets, positions, wallets, leaderboards22
Tokens: prices, holders, flows, trending21
Addresses: intelligence, balances, flows, history19
HyperCore (Hyperliquid): positions, balances, trades16
Entities: intelligence, balances, flows, history15
Alerts, labels and private entities (your own)15
Live transfer streams (WebSocket setup)11
Transfers, transactions, swaps and networks9
Intelligence update feeds and tags6
Risk scores for addresses and entities5
Account usage and billing3

Connect

You sign in with your Arkham account: the client opens Arkham, you create a key for it (or pick the one you made last time), and the client keeps it working. The full setup guide, including troubleshooting, is the MCP Server guide.

ClientHow
Claude (desktop, web, mobile)Customize → Connectors → Add custom connector, URL https://mcp.arkm.com/mcp. Under Advanced settings, set the OAuth Client ID to claude.
Claude Code/plugin marketplace add arkhamintelligence/arkham-mcp, then /plugin install arkham@arkham. Or: claude mcp add --transport http arkham https://mcp.arkm.com/mcp --client-id claude-code --callback-port 8765 --scope user
CursorAdd to Cursor, or add the arkham entry from mcp.json to ~/.cursor/mcp.json.
Codexcodex mcp add arkham --url https://mcp.arkm.com/mcp, then codex mcp login arkham
Gemini CLIgemini extensions install https://github.com/arkhamintelligence/arkham-mcp
KiroPowers → Add Custom Power → Import power from GitHub, https://github.com/arkhamintelligence/arkham-mcp/tree/main/kiro
VS Code, ChatGPT and othersAdd a remote MCP server with the URL https://mcp.arkm.com/mcp. The client registers itself, so Arkham's sign-in page shows its name as an unverified app.

Use an API key instead of signing in

Any client that can send a header can use a key from the API Dashboard:

Authorization: Bearer YOUR_API_KEY

Access and credits

Using the server needs an Arkham API plan or trial (Getting Access). Tool calls use the same API credits as the REST API, and each tool's description states its price; most lookups cost 5 credits or fewer. Each answer is capped at 4 MiB, so ask for narrow time ranges or fewer results, and use the API for large exports.

The tools read data, and write only to your own alerts, labels and private entities. None of them move funds or place trades. The server forwards each tool call's arguments and your key to api.arkm.com and keeps no conversation content.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
