Aura MCP Overview

The Aura MCP MCP server connects assistants to Aura's encrypted computation capabilities through MCP tools and prompts. It supports encrypted integer and floating-point arithmetic, composed calculations, operation discovery, latency checks, and encrypted-result saving. An optional public lesson explains fully homomorphic encryption using sample values, while the separate Aura AI application is not run by this package. Reach for it to learn about FHE or prototype supported numeric workflows from Cursor, Claude Desktop, VS Code, or another MCP client.

Primary Use Cases for Aura MCP:

Learn how fully homomorphic encryption handles numeric calculations
Run the public encrypted-computation lesson
Test encrypted sums, products, averages, and weighted sums
Measure request latency and save encrypted results

Frequently Asked Questions: Aura MCP Alternatives

The top-rated alternatives to Aura MCP in the Cryptography category include Signet MCP Tools, MCP Identity, APEX PSI. These servers offer complementary or alternative capabilities depending on your deployment stack and authentication requirements.

Aura MCP and its alternatives vary by runtime requirement (Node.js/npx, Python/uvx, Docker, or remote HTTP/SSE endpoints). Check the specification comparison table above to verify command requirements before installing.

It varies by server. Pricing, auth and license are declared by each maintainer and shown in the comparison table where provided — a dash means nothing was declared, so check that project's own site before assuming it's free.
