Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security98
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- 32 of 98 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail

- Actively maintained (last published 161 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability88
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 593 tokens (~59/item across 10 items; 4 tools + 6 resources), lean.Pass

Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "generate_deploy_link" implies "deploy" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_tolk_syntax ~114
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.
| Name | Type | Req | Description |
|---|---|---|---|
| entrypointFileName | string | yes | The main .tolk file to check (e.g., "main.tolk") |
| sources | object | yes | Object mapping filename -> source code content. Must include the entrypoint file. Example: {"main.tolk": "fun main(): int { return 0; }"} |
No output schema declared.
No examples provided.
compile_tolk ~178
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.
| Name | Type | Req | Description |
|---|---|---|---|
| entrypointFileName | string | yes | The main .tolk file to compile (e.g., "main.tolk") |
| optimizationLevel | integer | – | Optimization level 0-2 (default: 2) |
| sources | object | yes | 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 |
No output schema declared.
No examples provided.
generate_deploy_link ~162
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.
| Name | Type | Req | Description |
|---|---|---|---|
| amount | string | – | Amount in nanoTON to send with deploy message (default: "50000000" = 0.05 TON) |
| codeBoc64 | string | yes | 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) |
No output schema declared.
No examples provided.
get_compiler_version ~38
Returns the version of the Tolk compiler (from @ton/tolk-js WASM). Use this to check which compiler version is available.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
