AstraCipher Protocol — Cryptographic Identity & Trust for AI Agents (Open Source BSL-1.1)
Most developer tooling work still happens through a UI a human drives. Astracipher MCP server moves it into the conversation instead. AstraCipher Protocol — Cryptographic Identity & Trust for AI Agents (Open Source BSL-1.1).
The MCP registry provides MCP clients with a list of MCP servers, like an app store for MCP servers.
Installation goes through your MCP client rather than a global install: point it at ghcr.io/modelcontextprotocol/registry on a container image and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
The server publishes 1 tool. What each one is for:
Authentication — Publishing supports multiple authentication methods: - GitHub OAuth - For publishing by logging into GitHub - GitHub OIDC - For publishingAmong the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Astracipher's toolset — Authentication — is a fair guide to whether it matches your workflow. It is maintained by san-techie21; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Astracipher's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
