Flarelink

@flarelink/mcp

An MCP server that teaches your AI coding tool to build correctly on the Flarelink stack — Cloudflare auth (better-auth + KV sessions), D1, and R2 — from inside Cursor, Claude Code, Windsurf, and anything else that speaks MCP.

It hands the agent the security and cost rules up front (user-scoping, identifier-safe SQL, KV sessions, presigned R2) so the generated code is right the first time, instead of the agent guessing and you debugging.

Install

No install needed — run it with npx. Add it to your tool's MCP config:

Claude Code

claude mcp add flarelink -- npx -y @flarelink/mcp

Cursor / Windsurf / Claude Desktop (mcp.json / config):

{
  "mcpServers": {
    "flarelink": {
      "command": "npx",
      "args": ["-y", "@flarelink/mcp"],
      "env": { "FLARELINK_API_KEY": "flk_…" }
    }
  }
}

The FLARELINK_API_KEY is optional. Without it you still get all the knowledge + scaffolding tools. With it, the management tools (below) can drive your actual Flarelink projects. Mint a key at dash.flarelink.dev → API keys.

Tools

Tool	What it gives the agent
flarelink_stack_overview	The stack, cardinal rules, and deployment shapes. Read first.
flarelink_scaffold	How to bootstrap a complete working app (clone / one-click deploy) + file map.
flarelink_list_patterns	The catalog of canonical code patterns.
flarelink_get_pattern	Copy-pasteable code for one recipe (auth setup, route guards, identifier-safe D1, R2 upload/presign, wrangler bindings, SDK usage).
flarelink_sdk_reference	@flarelink/client signatures + return shapes (auth / storage / db).
flarelink_cost_patterns	Cloudflare cost-optimization guidance, with targeted hints for the feature you describe.

It also exposes the stack guide as a resource (flarelink://stack-guide) you can attach as context.

Management tools (need FLARELINK_API_KEY)

Drive your actual Flarelink projects from the editor. These route through the Flarelink dashboard API and act exactly as you would in the UI.

Tool	What it does
flarelink_whoami	Verify the key; show the user + active connection/project.
flarelink_list_projects	List projects on the active Cloudflare connection.
flarelink_list_databases	List the project's D1 databases.
flarelink_query_database	Run a (parameterized) SQL statement against a project D1.
flarelink_list_buckets	List the project's R2 buckets.

Without a key they return a clear "set FLARELINK_API_KEY" message. The key has the same access as your Flarelink login — treat it like a password.
