Struct McpConfig 

pub struct McpConfig {
    pub enabled: bool,
    pub transport: String,
    pub url: Option<String>,
    pub protocol_version: String,
    pub auto_resources: bool,
    pub tools: Vec<McpToolDecl>,
    pub prompts: Vec<McpPromptDecl>,
}

MCP registry settings. Mirrors the JSON shape consumed by clients (Claude Desktop, IDE integrations, …) but expressed in TOML so site authors can edit it alongside the rest of ssg.toml.

Hand-rolled Default so the transport and protocol_version fields carry the same defaults that #[serde(default = …)] applies during deserialisation — otherwise constructing the struct via McpConfig::default() (rather than parsing TOML) would leave both strings empty.

Fields

enabled: bool

Master toggle. When false, no mcp.json is written.

transport: String

Transport descriptor — currently always "http". Held as a string so future transports ("stdio", "sse") can land without bumping the schema.

url: Option<String>

Override the URL the transport listens on. When omitted, the emitter synthesises {base_url}/.well-known/mcp so the registry is self-describing.

protocol_version: String

MCP protocol version reported in the registry. Defaults to "2025-03-26", the version pinned across the public MCP servers we tested against during the v0.0.44 cycle.

auto_resources: bool

When true, walk .meta.json sidecars under site_dir and emit one MCP resource per public page. AC5 of #552.

tools: Vec<McpToolDecl>

Statically-declared MCP tools. Optional — most sites won’t expose any. Authors may extend this list in ssg.toml.

prompts: Vec<McpPromptDecl>

Statically-declared MCP prompt templates.
