Key features

  1. 01Attest and verify AI decisions
  2. 02Create signed, chained evidence anchored to Hedera
  3. 03Generate compliance reports and filings
  4. 04Check regulatory frameworks and jurisdiction gaps
  5. 05Manage incidents and human review

Use cases

  1. 01Record evidence for AI decisions
  2. 02Verify attestation chains and proofs
  3. 03Prepare regulatory compliance reports
  4. 04Track incidents requiring human review

MCP support

The server exposes attestation, verification, compliance, regulatory, governance, registry, and operations tools to MCP-compatible hosts. The default profile provides core tools; additional modules can be selected through an environment variable.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config

Environment variables to set
RUBRIC_API_KEYSecretRubric API key for Hedera mainnet anchoring. Optional — omit for free local PQ-signed attestation.

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
