+# surfpool
+
+Surfpool is a Solana development toolkit that provides a local validator environment, CLI tools, MCP server, GraphQL API, and a studio UI for building and testing Solana programs.
+
+## Overview
+
+Rust workspace with 9 crates: `cli` (main entry point), `core` (runtime), `mcp` (MCP server), `gql` (GraphQL API), `studio` (web UI), `subgraph` (indexing), `db` (storage), `types` (shared types), and `bench` (benchmarks).
+
+## Getting Started
+
+```bash
+cargo build                    # Build all crates
+cargo run -- --help            # Run the CLI
+cargo test                     # Run tests
+```
+
+## Architecture
+
+- **crates/cli** - Command-line interface (default member)
+- **crates/core** - Core Solana runtime and validator logic
+- **crates/mcp** - Model Context Protocol server
+- **crates/gql** - GraphQL API (juniper + actix-web)
+- **crates/studio** - Web-based studio UI
+- **crates/subgraph** - Subgraph/indexing support
+- **crates/db** - Database layer (diesel)
+- **crates/types** - Shared type definitions
+- **crates/bench** - Benchmarking
+
+## Key Files
+
+- `Cargo.toml` - Workspace root with all dependency versions
+- `crates/cli/src/main.rs` - CLI entry point
+- `crates/core/` - Core runtime logic
