Aura MCPCryptography · Local subprocess (stdio)Connect assistants to Aura encrypted computation. Explore Aura AI and run public numeric demos.49FairAuth: no auth requiredVerdict: choose Aura MCP for cryptography work as a local process; choose Hashproof for cryptography as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
AChoose Aura MCP when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: No auth required.
Choose Hashproof when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a local stdio subprocess transport.
- You want tools like
get_template_requirements, preview_template, issue_credential.

Hashproof tools 4
get_template_requirementsGet the required field keys and layout definition of an existing HashProof template. Free, no auth. Always call this before issuing with a template_slug you didn't create in this session.preview_templateRender a watermarked preview PDF from an INLINE template definition — free, nothing stored, no payment. Use this to iterate field positions (x, y, width, font_size) until the layout is right, then show the final PDF to the human for approval before issuing. page_width/page_height MUST match the background image's pixel dimensions. The PDF is written to a local file; if you can read PDFs, inspect it and adjust yourself.issue_credentialIssue a verifiable credential — COSTS $0.10 USDC (x402) or 1 API-key credit per call. Get explicit human approval before calling. Requires HASHPROOF_API_KEY or HASHPROOF_WALLET_PRIVATE_KEY in the MCP server env (if neither is set, the error explains both routes). With an API key the credential issues as the key's own entity: `issuer.slug` must match that entity or the call is rejected, so you cannot issue on behalf of another organization. The body follows the HashProof issueCredential schema: issuer{display_name,slug}, platform{display_name,slug}, holder{full_name}, context{type,title}, credential_type, title, values{...}, and optionally template_slug OR an inline template{...} (send only one). Returns id, verification_url, tx_hash and ipfs_cid. Full reference: https://hashproof.dev/skill.mdverify_credentialVerify an issued credential against three independent sources (database, IPFS, blockchain). Free, no auth. Returns status (active/revoked/expired/not_found), issuer verification and the credential data.

Frequently asked questions
Aura MCP is categorized under Cryptography and uses a local stdio subprocess. Hashproof belongs to Cryptography and uses a local stdio subprocess. Pick Aura MCP for cryptography work and Hashproof 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.
Aura MCP is listed as free. Auth: no auth required. Hashproof 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 aurafhe-mcp and hashproof as separate keys in the same mcpServers object, and your assistant will call tools from either one.
