Overview ¶
Package mcp is a minimal Model Context Protocol server over stdio: enough of the protocol (initialize, ping, tools/list, tools/call as newline-delimited JSON-RPC 2.0) for an agent to call notenv's tools, and nothing more. Hand-rolled deliberately: like internal/ui, it adds zero new supply-chain surface, which matters more than protocol breadth while the server is a prototype.
Requests are handled sequentially in arrival order; there is no cancellation and no server-initiated traffic. Handlers' results travel as text content. The transport's stdin/stdout belong to the protocol; prompts and logging elsewhere in notenv already go to /dev/tty and stderr, so a handler can run the full app stack without corrupting the stream.

Types ¶
type Server ¶
Server serves a fixed tool set over one stdio session.
type Tool ¶
type Tool struct {
Name string
Description string
InputSchema map[string]any
Handler func(ctx context.Context, args json.RawMessage) (string, error)
}
Tool is one callable tool: a name, the description an agent picks it by, a JSON-Schema input declaration, and the handler. A handler error becomes a tool-level error result (isError), not a protocol error: the agent gets to read it and adapt.
