## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 9 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 73/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1678 tokens (~186/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 50/100
  - Stability observed for 15 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (9)

### `check_feasibility` (~105 tokens)

Can Bedrock do this

Checks whether a user request can be built with a behavior pack and the @minecraft/server API. If it is blocked, returns why, the evidence behind that rule, and a workable alternative. Call this BEFORE writing any code or JSON: input simulation, file system access and network access do not exist in the Bedrock scripting API, and those are the most commonly hallucinated APIs.

Input parameters:

- `request` (string, required): The user request in their own words. Any language is accepted.

### `get_version_info` (~125 tokens)

Bedrock version and schema context

Returns which version number belongs where for this game version: min_engine_version (a three-part array), @minecraft/server module versions, the valid format_version values for every document type, and the list of recognised document types. format_version is an axis of its own and is unrelated to the game version. Call this before writing any behavior pack file.

Input parameters:

- `version` (string): Game version under data/, e.g. 1.26.40 or 1.26.40.5. Defaults to the newest available version. Marketing numbers (26.40) are rejected.

### `get_schema` (~253 tokens)

Schema summary for a document type

Summarises the schema of a Bedrock document type: required fields, valid format_version values, and the name, type and description of every field on that node. It does not return the raw schema — that is far too large. When a node has many fields the summary narrows and says what was shortened in the truncated field; use path to descend into a child node for full detail. Call this before writing a file to learn which fields are required and what format_version must be.

Input parameters:

- `path` (string): Path to descend into the schema, separated by "/". For example "minecraft:entity" or "minecraft:entity/components/minecraft:health". Omit it to get the root summary. An unresolvable path returns an e…
- `type` (string, required): Document type, e.g. "behavior/blocks", "behavior/entities", "behavior/spawn_rules". The full list is in the get_version_info output.
- `version` (string): Game version under data/, e.g. 1.26.40 or 1.26.40.5. Defaults to the newest available version. Marketing numbers (26.40) are rejected.

### `lookup_id` (~171 tokens)

Verify a vanilla identifier

Tells you whether a minecraft: identifier actually exists in this version and what kind it is (block, item, entity, biome, effect, enchantment, feature, dimension, camera preset, particle, potion). For a block it also returns the valid block states and the values they accept. An identifier without a namespace is treated as minecraft:. Verify every identifier here before writing it — an identifier that does not exist fails silently in the game.

Input parameters:

- `id` (string, required): Identifier, e.g. "minecraft:blaze" or just "blaze" without the namespace.
- `version` (string): Game version under data/, e.g. 1.26.40 or 1.26.40.5. Defaults to the newest available version. Marketing numbers (26.40) are rejected.

### `validate_json` (~189 tokens)

Validate Bedrock JSON against its schema

Validates a behavior or resource pack JSON file against the official schema and returns the JSON pointer, the violated rule and a readable message for every error. Unexpected property names and the valid enum values are included in the message. Run every JSON file you produce through this before handing it to the user.

Input parameters:

- `content` (string, required): The complete file content as text. Parse errors are reported too.
- `type` (string, required): Document type. A canonical name ("behavior/blocks/blocks"), a short form ("behavior/blocks") or a file path ("BP/blocks/ruby.json") are all accepted. The list of recognised types is in the get_versio…
- `version` (string): Game version under data/, e.g. 1.26.40 or 1.26.40.5. Defaults to the newest available version. Marketing numbers (26.40) are rejected.

### `validate_command` (~171 tokens)

Validate a Bedrock command

Validates a single Bedrock command line against the official command index: does the command exist, does the argument count match, are the selectors and block states valid. When no overload matches it returns the valid usages, and it tells you whether the command requires cheats. Run every command through this before giving it to the user. `execute ... run <command>` chains are resolved: the command after run is validated too, including nested execute.

Input parameters:

- `line` (string, required): A single command line, e.g. "/give @p diamond 1". The leading / is optional.
- `version` (string): Game version under data/, e.g. 1.26.40 or 1.26.40.5. Defaults to the newest available version. Marketing numbers (26.40) are rejected.

### `validate_script` (~193 tokens)

Compile an @minecraft/server script

Compiles a behavior pack script with the real TypeScript compiler against the actual @minecraft/server type definitions for that version. Returns diagnostics with line, column, TS error code and message, and reports which module versions it compiled against. Catch non-existent APIs and calls removed in later versions here — Bedrock scripting APIs written from memory are the most common source of output that fails silently.

Input parameters:

- `channel` (string): Module channel. Defaults to stable. If beta is requested but a module has no beta release it falls back to stable — the modules field in the result says which version each module was compiled against.
- `code` (string, required): The complete script content. JavaScript or TypeScript.
- `version` (string): Game version under data/, e.g. 1.26.40 or 1.26.40.5. Defaults to the newest available version. Marketing numbers (26.40) are rejected.

### `validate_python` (~199 tokens)

Validate an automation script

Validates a Python automation script that runs OUTSIDE the game, on three axes: Python syntax (using the real interpreter), Minecraft commands embedded in the script (against the official command index), and the shape of the /connect WebSocket message envelope. For behavior pack scripts use validate_script instead — Python does not run inside a pack. The embedded command check is the most valuable one: a command written from memory can look syntactically fine and still do nothing in the game. Only strings starting with / are treated as commands. If syntax could not be checked, syntaxChecked is false in the result; ok:true alone does not mean the syntax is valid.

Input parameters:

- `code` (string, required): The complete Python script content.
- `version` (string): Game version under data/, e.g. 1.26.40 or 1.26.40.5. Defaults to the newest available version. Marketing numbers (26.40) are rejected.

### `review_pack` (~173 tokens)

Validate a whole pack

Validates every file of a behavior or resource pack in one call: it applies the right validator to each file (JSON schema, script compilation, command syntax) and then runs the checks a schema structurally cannot do — identifier consistency, filename rules, manifest module type, texture keys, component names, Molang queries and loot/trade table paths. This is the LAST step before handing a pack to the user, and it is both faster and broader than validating each file separately.

Input parameters:

- `files` (array, required): The files in the pack. Include the manifest — several checks depend on it.
- `version` (string): Game version under data/, e.g. 1.26.40 or 1.26.40.5. Defaults to the newest available version. Marketing numbers (26.40) are rejected.

## Common questions

### What is the CodeCraft MCP server?

CodeCraft is an MCP server listed in the public MCP registry as io.github.TanerTalas/codecraft. Checks whether generated Minecraft Bedrock content will actually load. Nine read-only tools. This page covers its hosted endpoint (https://codecraft-ashy-seven.vercel.app/mcp).

### Is the CodeCraft MCP server safe to use?

CodeCraft scores 73 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the CodeCraft MCP server expose?

CodeCraft exposes 9 tools: check_feasibility, get_version_info, get_schema, lookup_id, validate_json, and 4 more. Their descriptions and schemas cost roughly 1,579 tokens of context every time the server is loaded.

### Does the CodeCraft MCP server require authentication?

No. We connected to CodeCraft without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the CodeCraft MCP server still maintained?

CodeCraft is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
