`@danielblomma/cortex-mcp` is a local context platform for coding assistants that indexes codebases into structured entities and exposes that context over MCP (JSON-RPC over stdio).
From the registry: Persistent knowledge system with OWL-RL reasoning and 22 MCP tools. Local-first.

Install in your client
Paste into the AI you're chatting with — it will figure out the rest
Please install the `cortex` MCP server into my current AI client (that's you).
Required prerequisites (do these first if not already done):
- **Node.js 18+** — Node.js 18 or higher required.
- **Install cortex-mcp globally** — Install the @danielblomma/cortex-mcp package. Run: `npm i -g @danielblomma/cortex-mcp` (https://www.npmjs.com/package/@danielblomma/cortex-mcp)
- **Bootstrap project** — Run `cortex init --bootstrap` in the repo you want to index. Run: `cortex init --bootstrap`
Canonical MCP server config (stdio transport):
- command: `cortex`
- args: ["mcp"]
- optional environment variables:
- `CORTEX_PROJECT_ROOT`: Absolute path to the project to index. (example: `/absolute/path/to/your-project`)
Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.Tools (7)
