MCP support
The plugin adds stella's MCP server to AI coding agents; the documentation also covers anonymized and law-specific MCP addresses.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Details
From the project README
stella plugins
Plugins that connect AI coding agents to stella, the
open-source legal workspace. The stella plugin adds stella's MCP server and a
get-started skill that signs in and verifies the connection.
Claude Code
claude plugin marketplace add stella/plugins
claude plugin install stella@stella
Codex
codex plugin marketplace add stella/plugins
codex plugin add stella@stella
Gemini CLI
gemini extensions install https://github.com/stella/plugins
Then ask your agent to connect to stella. It starts the sign-in, shows you a link to open in your browser, and confirms the connection once the sign-in succeeds.
Self-hosted instances and the other MCP addresses (/mcp-anonymized,
/mcp-law) are covered in the
connection guide.
MCP Registry
The server is published as io.github.stella/stella from server.json.

Comments
New to MCP?
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.
