Plugin	Description
adastra	Slash commands for the public Ad Astra MCP server at mcp.adastracomputing.com.

Install

Add this marketplace to your Claude Code:

/plugin marketplace add Ad-Astra-Computing/adastra-claude-plugins

Then install a plugin from it:

/plugin install adastra@adastra-claude-plugins

Reload plugins or restart the session, and the new slash commands appear under the adastra: namespace.

What you get

After installing the adastra plugin, the following slash commands are available:

• /adastra:products — list Ad Astra products (active, research, future)
• /adastra:org — show the organization profile and lab principles
• /adastra:contact — show contact channels
• /adastra:submit-intent — submit a signed contact intent through the MCP server

The plugin's .mcp.json adds the public Ad Astra MCP server at https://mcp.adastracomputing.com to the session. The server is read-mostly. The one write tool (submit_intent) is rate-limited per hashed IP, requires explicit contact consent, and returns a verifiable HMAC receipt.

Security

• The plugin makes no outbound calls of its own. All tool calls go through the MCP server, which is operated by Ad Astra Computing.
• The MCP server validates Origin, enforces a JSON content-type, rejects oversize bodies, and rate-limits the write path per hashed IP. See https://adastracomputing.com/mcp for the public security posture.
• No credentials are required. No data leaves the user's machine except the fields they explicitly include in a submit_intent call (name, email, message, intent type).
