First indexed and scored.

## MCP tools (4)

### `get_compiler_version` (~38 tokens)

Returns the version of the Tolk compiler (from @ton/tolk-js WASM). Use this to check which compiler version is available.

### `compile_tolk` (~178 tokens)

Compiles Tolk smart contract source code using @ton/tolk-js. Provide source files as a map of filename->content. The entrypoint file must be included. Standard library imports (@stdlib/*) are resolved automatically. Returns compiled Fift code, BoC (Bag of Cells) in base64, and the code hash.

Input parameters:

- `entrypointFileName` (string, required): The main .tolk file to compile (e.g., "main.tolk")
- `optimizationLevel` (integer): Optimization level 0-2 (default: 2)
- `sources` (object, required): Object mapping filename -> source code content. Must include the entrypoint file. Example: {"main.tolk": "fun main(): int { return 0; }"}
- `withStackComments` (boolean): Include stack layout comments in Fift output

### `check_tolk_syntax` (~114 tokens)

Checks Tolk source code for syntax and type errors without returning full compilation output. Faster feedback loop for iterative development. Returns OK + code hash on success, or error details on failure.

Input parameters:

- `entrypointFileName` (string, required): The main .tolk file to check (e.g., "main.tolk")
- `sources` (object, required): Object mapping filename -> source code content. Must include the entrypoint file. Example: {"main.tolk": "fun main(): int { return 0; }"}

### `generate_deploy_link` (~162 tokens)

Generates a TON deployment deeplink for a compiled Tolk contract. Accepts the compiled code BoC (base64) and optionally initial data BoC. Computes the contract address and returns ton:// deeplinks for wallet deployment.

Input parameters:

- `amount` (string): Amount in nanoTON to send with deploy message (default: "50000000" = 0.05 TON)
- `codeBoc64` (string, required): Base64-encoded BoC of the compiled contract code (from compile_tolk output)
- `initialDataBoc64` (string): Base64-encoded BoC for the contract initial data cell (default: empty cell)
- `workchain` (number): Target workchain ID (default: 0, the basechain)
