Install Astracipher

Pick your client, then add it in one click or paste the config.

No confirmed install command yet

We only publish a config when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for astracipher, and we’d rather show nothing than a guess you’d paste into your client.

Overview

The astracipher MCP server is described as providing cryptographic identity for AI agents through W3C DIDs, Verifiable Credentials, and post-quantum cryptography. The supplied repository excerpt is for the MCP Registry rather than astracipher, so it does not document the server's tools, transport, setup, or external connections. Consider it when evaluating agent identity and credential workflows, but verify implementation details before adoption.

Use cases

  • Evaluate W3C DID support for AI agent identity
  • Assess Verifiable Credential workflows for agents
  • Review post-quantum cryptography options for agent systems

Key features

  • W3C Decentralized Identifiers
  • Verifiable Credentials
  • Post-quantum cryptography
  • Cryptographic identity for AI agents

How Astracipher works

What astracipher MCP server does

The listing describes astracipher as a cryptographic identity layer for AI agents. Its stated scope includes three areas: W3C Decentralized Identifiers (DIDs), Verifiable Credentials, and post-quantum cryptography. These terms indicate an intended focus on representing agent identities, working with digitally verifiable claims, and addressing cryptographic methods designed to remain suitable in the presence of quantum-computing threats.

The available description does not explain whether astracipher creates, resolves, signs, verifies, stores, or exchanges any of these objects. It also does not identify a wallet, identity provider, credential registry, blockchain, database, or other external system that the server connects to. Those details should be confirmed from the project's implementation or complete documentation.

Tools and capabilities

The astracipher MCP server is associated with cryptographic identity for AI agents and names W3C DIDs, Verifiable Credentials, and post-quantum cryptography as its main capability areas.

For integration planning, treat the following as stated scope rather than a complete API description:

  • W3C Decentralized Identifiers for agent identity
  • Verifiable Credentials for digitally verifiable claims
  • Post-quantum cryptography

The listing does not establish which operations are available for any of these areas. In particular, it does not confirm key generation, credential issuance, credential presentation, signature verification, DID resolution, key rotation, revocation, or interoperability with a particular identity ecosystem.

Limitations and notes

The supplied repository excerpt does not appear to be astracipher's project documentation. It describes the Model Context Protocol Registry, including its registry API, publisher CLI, Docker development environment, Go requirements, PostgreSQL usage, and registry authentication. None of those details establish how astracipher itself runs or how its MCP interface is configured.

Before using the astracipher MCP server in a production identity workflow, verify the canonical repository contents and documentation for supported DID methods, credential formats, cryptographic primitives, key custody expectations, and any limitations around post-quantum support. Do not infer those properties solely from the short listing description.

Frequently Asked Questions about Astracipher

astracipher is an MCP server that provides cryptographic identity capabilities for AI agents, covering W3C Decentralized Identifiers (DIDs), Verifiable Credentials, and post-quantum cryptography.

The available README describes the separate MCP Registry project and its Docker, Go, and PostgreSQL development setup, so those instructions should not be applied to astracipher without verification.

It states only that the project concerns agent cryptographic identity, W3C DIDs, Verifiable Credentials, and post-quantum cryptography; supported operations and schemas are not documented.
