ActionProof vs Hive Zk Attestation
A side-by-side look at the ActionProof and Hive Zk Attestation MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose ActionProof for cryptography work as a local process; choose Hive Zk Attestation for cryptography over a hosted endpoint. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose ActionProof when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
ACTIONPROOF_KEY_PATH.
Choose Hive Zk Attestation when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a remote HTTP/SSE transport.
- You want tools like
zk_attest_agent_state, zk_verify_proof, zk_anchor_to_base.

Frequently asked questions
ActionProof is categorized under Cryptography and uses a local stdio subprocess. Hive Zk Attestation belongs to Cryptography and uses a remote HTTP/SSE transport. Pick ActionProof for cryptography work and Hive Zk Attestation for cryptography.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
ActionProof has no declared pricing — check the project's own site. Hive Zk Attestation has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add actionproof and hive-zk-attestation as separate keys in the same mcpServers object, and your assistant will call tools from either one.
