Paste into the AI you're chatting with — it will figure out the rest
Please install the `cruxible-core` MCP server into my current AI client (that's you).
Required prerequisites (do these first if not already done):
- **Install cruxible-core with MCP extras** — Install the cruxible-core Python package with MCP extras via pip or uv. Run: `pip install "cruxible-core[mcp]"` (https://pypi.org/project/cruxible-core/)
Canonical MCP server config (stdio transport):
- command: `cruxible-mcp`
- args: []
- optional environment variables:
- `CRUXIBLE_MODE`: Permission mode (read_only, graph_write, admin). Controls which MCP tools are exposed. Defaults to read-only if omitted. (example: `admin`)
Note: Binary cruxible-mcp is installed by the cruxible-core[mcp] package.
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.Note: Binary cruxible-mcp is installed by the cruxible-core[mcp] package.
