Specialist roles for your AI assistant, loaded on demand.
Agents-Core is a local MCP server that gives AI clients a library of expert personas, skills, rules and reasoning patterns, and switches between them as the conversation changes.
What you get
Personas
About 44 roles: software engineer, DevOps, security, lawyer, analyst, tutor and more.
Skills and implants
Reusable domain knowledge and reasoning patterns, attached to a role only when the task needs them.
Routing
The server picks the right role for a request, and keeps it for follow-up messages without extra calls.
Subagent contracts
Delegated work gets a compact, task-scoped role and its result is validated against a contract.
Repository memory
Interaction history and notes stay in your own project, searchable by later sessions.
Local first
Runs on your machine over stdio or a loopback HTTP daemon. Your library syncs through your own Git repository.
Works with
Any MCP client. The installer registers Agents-Core in the clients it finds on your machine, such as Claude Code and Codex.
