v0.11.0 — Unified Config & MCP Server

Promote refrakt.config.json from a site-only file into the unified root config defined in ADR-010. Add type-level support for plugins, plan, site, and sites, normalize the three valid input shapes (flat / singular site / plural sites) into a canonical internal form, and publish a JSON Schema so editors can autocomplete and validate the file.

Replace the lazy runPlugin import-on-demand pattern in packages/cli/src/bin.ts with a first-class discoverPlugins() helper that returns the full set of installed plugins. The helper has four consumers in v0.11.0 — CLI dispatch, refrakt --help, refrakt plugins list, and the new MCP server — and centralizing the logic eliminates three different implementations of the same scan.

Add three optional fields to the CliPluginCommand interface so plugin commands can declare structured input/output schemas and an MCP-friendly handler that bypasses argv parsing. Existing plugins keep working unchanged — the fields are purely additive.

Switch the CLI's plugin dispatch in packages/cli/src/bin.ts from blind import('@refrakt-md/<namespace>/cli-plugin') to a discoverPlugins() lookup. This produces a friendlier "did you mean?" error when a namespace is misspelled (since we know the full set of installed plugins) and centralizes plugin loading on the new helper.

Surface the installed plugin set in two places: the top-level refrakt --help output (so users discover available namespaces without reading docs) and a dedicated refrakt plugins list command (canonical machine-readable output for tooling, including MCP clients debugging their setup).

Site-scoped commands (inspect, contracts, validate, scaffold-css, package validate) need to know which site they are operating on when the project declares multiple. Add a --site <name> flag that selects an entry from the normalized sites map; for single-site projects the flag is optional and resolves to the lone entry.

Add a lint pass to refrakt package validate that checks a package's cli-plugin export for structural issues — missing namespace, missing descriptions, malformed inputSchema, namespace conflicts with already-installed plugins. Catches problems at package-publish time rather than at runtime when the MCP server tries to advertise the broken tool.

Update all five framework adapter packages — @refrakt-md/sveltekit, @refrakt-md/astro, @refrakt-md/nuxt, @refrakt-md/next, @refrakt-md/eleventy — to accept a site?: string option. Each adapter resolves its target site via the shared normalizer from WORK-159, then reads contentDir, theme, target, packages, routeRules, icons, backgrounds from the resolved site entry instead of the top-level config. Single-site projects and the legacy flat shape continue to work without changes; multi-site repos pick a target per adapter.

Wire the @refrakt-md/plan CLI commands with the new schema fields from WORK-161 so the MCP server exposes them as cleanly typed tools. Each command gets a JSON Schema for its inputs and an mcpHandler that bypasses argv parsing and accepts a structured object directly.

Wire @refrakt-md/plan to the unified refrakt.config.json. plan init scaffolds the config (creating it or extending an existing one with a plan section), and plan serve / plan build / other plan commands read plan.dir from the loaded config instead of relying solely on the --dir flag and defaults. The plan section currently exposes only dir; specs path remains derived from dir (a child folder), and surfacing it as a config field can come later if real-world projects demand it.

Create the @refrakt-md/mcp package: stdio MCP server entry point, auto-detection of plan and site contexts from the unified config and the filesystem, and the initial set of core CLI-mirroring tools (refrakt.inspect, refrakt.contracts, refrakt.validate, refrakt.reference, refrakt.package_validate).

Wire plugin-contributed tools (notably the @refrakt-md/plan commands) into the MCP server via discoverPlugins(), and implement the read-only resources (refrakt://detect, refrakt://reference, refrakt://contracts, refrakt://rune/<name>, refrakt://plan/*) so agents that prefer pull semantics have first-class URIs.

Add a small migration command that rewrites a flat-shape refrakt.config.json into the nested form (site.* and explicit plugins). Optional for users — the flat shape stays valid indefinitely — but useful for projects adopting the unified config or moving to multi-site.

Move site/refrakt.config.json to a unified refrakt.config.json at the repo root, declaring plugins, the plan section, and sites.main (or whatever name we settle on) for the existing site. Validates the design against our own project and gives us a multi-site-ready structure for any future additions (separate plan dashboard site, blog, etc.).

create-refrakt currently writes a flat-shape site/refrakt.config.json for site projects and (via plan init) no config at all for plan projects. Update both paths to produce the new unified root-shape config — site projects get a sites.main section, plan projects get a plan section, and any combined scaffolds (future) declare both.

Document the unified refrakt.config.json at site/content/docs/configuration/. Cover the three valid shapes (flat / singular site / plural sites), each section (plugins, plan, site/sites), the multi-site workflow, and the migration story for existing flat-shape configs.

Document the new @refrakt-md/mcp server (registration, tool reference, resource reference) at site/content/docs/mcp/, update the existing plugin authoring docs to cover the new cli-plugin schema fields (inputSchema, outputSchema, mcpHandler), and add a brief pointer in the root CLAUDE.md so AI agents know the MCP server exists when registered.
