# Lemma Oracle
> Give AI proven facts.
Lemma is a cryptographically verified truth layer for agent AI. It lets AI
reason over confidential data via zero-knowledge proofs, selective
disclosure, and tamper-evident provenance — while raw content stays
encrypted.
Every attribute an AI reads through Lemma carries permanent provenance:
who issued it, which schema defined it, how it was proven, and where its
verification record is anchored.

## MCP server
`@lemmaoracle/mcp` is the **Model Context Protocol (MCP) server** for Lemma,
published on npm and built with the official **MCP SDK**
(`@modelcontextprotocol/sdk`). Point Claude Desktop or any MCP-compatible
agent at it:
```json
{
"mcpServers": {
"lemma": {
"command": "npx",
"args": ["-y", "@lemmaoracle/mcp"],
"env": { "LEMMA_API_KEY": "YOUR_API_KEY" }
}
}
}
```
