Returns a guide to all available 5eMCP tools and when to use each. Call this first when unsure which tool to reach for — it explains the decision between omnisearch vs typed search vs _get tools, class feature lookups, book content, DM calculators, and the fetch_content fallback.

Returns the manifest build time, file counts by content type, and any unknown content types (those without typed handlers).

List all available source abbreviations with their content types and files. Optionally filter by content type.

Fallback tool — fetch any file in the manifest by content type and file name. Prefer the typed _search and _get tools (spell_search, monster_get, class_get, etc.) when available. Use fetch_content for content types that don't have a typed tool, or when you need raw file access. Omit file_name to list available files for a content type. Returns tag-resolved, metadata-stripped JSON.

The ruleset param selects the correct edition: '2024' returns the 2024 XPHB version (e.g. XPHB Wizard), '2014' returns the classic PHB version. For features at a specific level use classfeature_search. For subclass details use subclass_get or subclassfeature_search.

Search D&D 5e subclass features by name, class, or subclass. Returns features from the subclassFeature array embedded in class files. Use class_name to filter to a parent class (e.g. 'Wizard').

Search across ALL D&D 5e content types simultaneously — spells, monsters, items, classes, subclasses, feats, races, backgrounds, conditions, and more. Start here when you don't know what type of content you need. Each result includes an entityType field so you can tell what kind of thing was found. For deeper filtering within a single type, follow up with the typed _search tool (e.g. spell_search, monster_search). Homebrew is included by default.

Get content from a D&D 5e sourcebook or adventure by source abbreviation (e.g. SCC, EGW, PHB). Uses a drill-down navigation model to minimise token usage — fetch only what you need:

1. Omit section → returns top-level section/chapter names (TOC).

2. Provide section only → if the section has subsections, returns their names; if it is a leaf (no subsections), returns its full text.

3. Provide section + subsection → returns the rendered text of just that subsection.

4. Not found → returns an error and the available names at that level. Supports book sources (PHB, DMG, SCC, EGW…) and adventure content (SCC-CK, COS…). Section and subsection filters are case-insensitive substring matches.

Calculate the Challenge Rating (CR) for a custom monster given its defensive and offensive stats. Uses the DMG Appendix B algorithm: defensive CR is derived from HP (adjusted for damage immunity, resistance, or vulnerability) and AC; offensive CR is derived from DPR and attack bonus (or save DC). The two are averaged to produce the final CR. Provide at least one of attackBonus or saveDc for the offensive calculation.

Look up the expected stat ranges for a given Challenge Rating from the DMG reference table. Returns proficiency bonus, expected AC, HP range, attack bonus, DPR range, and save DC. Useful for scaling a homebrew monster up or down to a target CR, or for quickly checking whether a monster's stats are appropriate for its intended CR.

Evaluate the difficulty of a D&D 5e encounter given the party composition and monster CRs. Supports both 2014 (classic) and 2024 (one D&D) rulesets. 2014 mode: uses four difficulty tiers (easy/medium/hard/deadly) with a monster count XP multiplier. 2024 mode: uses three difficulty tiers (low/moderate/high) with no multiplier. Both modes add a 'trivial' tier below easy/low and an 'absurd' tier above deadly/high. Returns total XP, adjusted XP (2014 only), difficulty label, and full threshold breakdown.

Generate individual treasure loot for a monster of a given Challenge Rating, based on the DMG individual treasure tables. Returns all possible outcomes for the appropriate CR bracket (Challenge 0-4, 5-10, 11-16, or 17+) with their d100 range, probability percentage, and average coin amounts (using dice average values). Roll a d100 to select a row, or use the average coins for a quick reference.
