Ask about a mash temperature, a hop, an off-flavour or a shortcut and get what the channel actually said, with the video and the second it was said. Nothing is generated here: your assistant writes the answer from the evidence.
Paste it into any MCP client. Authentication: none. Read-only: the server only ever returns claims from the graph.
Each video was transcribed, segmented and extracted into self-contained claims with a speaker, a timestamp, a polarity and a scope, then linked to the ingredients, styles and techniques it is about.
Every tool returns claims, not prose: polarity (works, fails, no difference), evidence type, the numbers stated, the experiment statistics, corroboration across videos and a timestamped YouTube link.
brew_answer
Combines claim search, exact measurements, exBEERiment verdicts, fault diagnosis, no-difference findings and safety warnings as the question needs, and draws the sources card itself.
ask_brewing
Hybrid semantic search, reranked, expanded through the graph. Pass a style and advice scoped to another style is flagged, never served silently.
measurements_for
"What temperature for an IPA primary?" as one query over 4,100 unit-normalised measurements, scope expanded through the style hierarchy.
experiment_results
The split-batch triangle tests: tasters, correct picks, p-value, significance, and the verdict as stated.
diagnose_fault
Causes, what prevents it and what fixes it after the fact, each backed by the claims that say so.
recipe
Grain bill, hop schedule, yeast and the target numbers for a recipe the channel brewed.
ingredient_profile
A hop, malt, yeast or adjunct: what it does, what it is typical for, what it substitutes, and where it was used.
compare
Two ingredients, techniques or pieces of gear side by side, with the tests that put them head to head.
what_can_i_skip
The channel's signature result: the steps and variables blind tasters could not tell apart.
who_said_what
What Martin Keen, Will Lovell, Jordan Folks, John Palmer or any guest actually said, with timestamps.
how_views_changed
Claims on a topic in date order, including where a later video disagrees with an earlier one.
safety_check
Pressure vessels, glass, sanitiser contact, CO2 in enclosed spaces: the safety-critical claims that touch your plan, surfaced regardless of rank.
show_answer_sources
Renders the entities, relations, claims and videos behind an answer as an in-chat card. Called once, after the specialised tools.

skip_check | Can I skip this step? | What the channel's blind tests say about dropping a step. |

How answers are built. Nothing is generated on this server. Each tool returns the claims that match, and your assistant writes the answer from that evidence and shows where it came from. Brülosophy's most common finding is no difference; the tools report it as such rather than implying an effect.
