Common questions

Is Arkham safe?

It passed 4 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 2 days ago, and the latest version (1.0.4) reached the registry 2 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

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:

Area	Tools
Polymarket: markets, positions, wallets, leaderboards	22
Tokens: prices, holders, flows, trending	21
Addresses: intelligence, balances, flows, history	19
HyperCore (Hyperliquid): positions, balances, trades	16
Entities: intelligence, balances, flows, history	15
Alerts, labels and private entities (your own)	15
Live transfer streams (WebSocket setup)	11
Transfers, transactions, swaps and networks	9
Intelligence update feeds and tags	6
Risk scores for addresses and entities	5
Account usage and billing	3

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.

Client	How
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`
Cursor	Add to Cursor, or add the `arkham` entry from `mcp.json` to `~/.cursor/mcp.json`.
Codex	`codex mcp add arkham --url https://mcp.arkm.com/mcp`, then `codex mcp login arkham`
Gemini CLI	`gemini extensions install https://github.com/arkhamintelligence/arkham-mcp`
Kiro	Powers → Add Custom Power → Import power from GitHub, `https://github.com/arkhamintelligence/arkham-mcp/tree/main/kiro`
VS Code, ChatGPT and others	Add 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.
