## 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 2026-11-05.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 66/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1933 tokens (~193/item across 10 items; 10 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 98/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 95% 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 10 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Install

### How do I install the Nightbreak Forge MCP server?

Nightbreak Forge is a hosted endpoint at https://forge.nightbreak.io/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (10)

### `search_plugin_source` (~225 tokens)

Search the EliteMobs, MagmaCore, BetterStructures, FreeMinecraftModels, CannonRTP and ResurrectionChest source code for a query. By default searches every mirrored repo by file content (grep). MagmaCore contains shared core functionality (Lua engine, base entity tables, scripting helpers) used by every plugin — always check it for hooks, helpers, or context methods that feel like they should be common across plugins. FreeMinecraftModels (freeminecraftmodels) has its own LuaItemTable / LuaPropTable and prop-specific hooks. Use this BEFORE answering plugin-specific questions or generating Lua/YAML files.

Input parameters:

- `max_results` (number): Default 20.
- `mode` (string): "content" (default) greps file contents; "path" matches file paths.
- `path_prefix` (string): Optional. Restrict to a subdirectory like "src/main/java/".
- `query` (string, required): Text or regex to grep for. Symbol names, hook names, error messages.
- `repos` (array): Optional. Defaults to every mirrored repo.

### `fetch_plugin_source_file` (~104 tokens)

Fetch a file from a mirrored plugin source repo. Optional line slicing for large files.

Input parameters:

- `line_end` (number): Optional. Read up to and including this line.
- `line_start` (number): Optional. Read from this line (1-indexed).
- `path` (string, required): Repo-relative path, e.g. "src/main/java/com/magmaguy/elitemobs/powers/lua/LuaPowerRuntime.java".
- `repo` (string, required)

### `get_local_lua_reference` (~360 tokens)

Read the current Nightbreak Forge local Lua validator/editor reference. Use this to see which hooks, fields, methods, exact values, and handle helpers the editor currently knows about. **Pass `script_type` matching the file you are working on:** `"lua-power"` (default, EliteMobs boss powers — includes context handles, `em`, and exact values), `"fmm-script"` (FMM props), or `"npc-script"` (EliteMobs NPC scripts in `npc_scripts/`), or `"mind-behavior"` (EliteMobs Mind AI programs in `behaviors/`, selected by a boss's `behavior` field), `"fmm-pet-behavior"` (FreeMinecraftModels pet behavior modules in `pet_behaviors/`, id `fmm:pet/<file name>`; loaded from FMM 2.13.0), or `"em-enchantment-script"` / `"fmm-enchantment-script"` (the Lua effect of an EliteMobs or FreeMinecraftModels enchantment in `enchantments/`). Each returns that script type's own hooks and `context.*` namespaces — the boss reference does NOT contain NPC, FMM, Mind or enchantment APIs, so query the matching type.

Input parameters:

- `scope` (string): Optional scope. For lua-power: "hooks", "context", "boss", "player", "event", "script", "handles", "em", or "values". For fmm-script/npc-script: "hooks", "context", or a context namespace name (e.g.…
- `script_type` (string): Which script type's reference to return. Defaults to "lua-power".

### `validate_lua_power_draft` (~437 tokens)

Validate a draft Lua script against the local Nightbreak Forge Lua validator. Use this before finalizing generated Lua files to catch unknown helpers, invalid fields, or malformed file structure. **IMPORTANT: pass `script_type` matching the file you are generating.** Use `"lua-power"` (default) for EliteMobs custom-boss Lua powers (files in `powers/`), `"fmm-script"` for FreeMinecraftModels prop scripts (files in `scripts/`), `"npc-script"` for EliteMobs NPC scripts (files in `npc_scripts/`), `"mind-behavior"` for Mind programs and modules (files in `behaviors/`), `"fmm-pet-behavior"` (FreeMinecraftModels pet behavior modules in `pet_behaviors/`, id `fmm:pet/<file name>`; loaded from FMM 2.13.0), or `"em-enchantment-script"` / `"fmm-enchantment-script"` for EliteMobs or FreeMinecraftModels enchantment scripts (files in `enchantments/`). They have different valid hook names and context namespaces — passing the wrong type produces false-positive errors (e.g. `on_right_click` is valid for `fmm-script`, `on_npc_interact` for `npc-script`, but both are rejected for `lua-power`).

Input parameters:

- `content` (string, required): Full Lua script file content to validate.
- `path` (string): Optional path such as "powers/example.lua" or "scripts/fireball_wand.lua" for reporting context.
- `script_type` (string): Which validator ruleset to apply. `"lua-power"` for EliteMobs boss powers, `"fmm-script"` for FMM prop scripts, `"npc-script"` for EliteMobs NPC scripts, `"mind-behavior"` for behaviors/ programs and…

### `search_wiki` (~125 tokens)

Search the Nightbreak wiki for relevant pages and snippets. Matching is by word and case-insensitive, ranked by title, page name and body. Each result has a `page` value to pass to fetch_wiki_page. Use for high-level docs, examples, and tutorials — not for symbol verification (use search_plugin_source for that).

Input parameters:

- `max_results` (number): Maximum number of results to return. Defaults to 10.
- `query` (string, required): Keywords to search for, such as "lua power files", "creating bosses", or "elitescript bridge".

### `fetch_wiki_page` (~102 tokens)

Fetch and extract readable content from a specific Nightbreak wiki page such as "EliteMobs/lua_getting_started". Page names change as the wiki grows: take them from search_wiki results. A missing page returns `suggestions` with the closest existing pages.

Input parameters:

- `path` (string, required): Wiki page path relative to the site root, for example "EliteMobs/lua_getting_started" or "EliteMobs/creating_bosses".

### `get_authoring_notes` (~57 tokens)

Where each config type's files go and the plugin rules Forge's own assistant follows: per-type notes, the newer plugins' knowledge, boss movement and combat AI, and the Lua hook quick reference. Read it once before writing files.

### `list_config_types` (~79 tokens)

The config file types Forge knows for the released plugins, with each type's plugin, label, server path, format and wiki page. Pass a type to get_config_schema or as the path when validating.

Input parameters:

- `plugin` (string): Optional plugin id to filter by, such as "elitemobs", "betterstructures" or "fmm".

### `get_config_schema` (~102 tokens)

One config type's fields as Forge edits and validates them: key, value type, default, whether it is required, description and allowed values. Long option lists are shortened; pass field to get one field with all its options.

Input parameters:

- `field` (string): Optional field key; returns only that field, with every allowed value.
- `type` (string, required): A type from list_config_types, such as "custom-boss" or "fmm-pet".

### `validate_config_files` (~136 tokens)

Validate plugin config files (YAML and Lua) with Forge's validator: required fields, allowed values, plugin rules, Lua analysis, and references between the files you send (a boss's powers, a dungeon's bosses). Send each file with its server path, such as "plugins/EliteMobs/custombosses/frost_king.yml", so Forge can tell its type. A reference to a file you did not send is reported as not found in the workspace, which here means this call's files. Up to 50 files per call. Nothing is stored.

Input parameters:

- `files` (array, required): The files to check together.
