| 750 | reasonix mcp import |

| 755 | --env K=V set an environment variable (repeatable, stdio) |
| 756 | --header K=V set an HTTP header (repeatable, remote) |
| 757 | |
| 758 | Examples: |
| 759 | reasonix mcp add fs npx -y @modelcontextprotocol/server-filesystem . |
| 760 | reasonix mcp add stripe --http https://mcp.stripe.com --header "Authorization=Bearer $STRIPE_KEY" |

| 762 | CLI config changes take effect on the next session. Inside a running chat, use |
| 763 | /mcp add to save and connect a server immediately. Installing a server is also |
| 764 | its launch authorization; there is no separate trust step. Remote OAuth, when |
| 765 | requested by the server, is completed with reasonix mcp auth <name> and stored |
| 766 | in Reasonix-private MCP state. |
| 767 | |
| 768 | Servers declared by project reasonix.toml or .mcp.json are trusted configuration |
| 769 | and need no separate launch confirmation. Project entries override same-name |
| 770 | global entries; within a project, reasonix.toml overrides .mcp.json. Writer or |
| 771 | destructive annotations never trigger per-call approval. Explicit deny rules |
| 772 | still win; Plan Mode and strict read-only subagents may filter which tools are |
| 773 | available.`) |
