What this MCP does

Reports which domains AI answer engines cite across buyer categories and question types, including citation rates and source roles.

mri_get_category
Get an MRI category
Return one category's question shapes (best tools, how buyers choose, comparisons, top lists, problem-first research, is it worth it, news) and the evidence state of each: published with rates, collecting, or not collectable.
Read only Idempotent
Input schema
{'type': 'object', 'required': ['category'], 'properties': {'category': {'type': 'string', 'description': 'Category key from mri_list_categories, e.g. cybersecurity.'}}, 'additionalProperties': False}
mri_get_cited_sources
Which sources AI engines cite
Ranked source domains that AI answer engines cite for one category and question shape, with citation rate (share of monitored answer runs citing the domain), rank, percentile and source role (editorial publication, vendor-owned, analyst research, community, academic/government, market database, wire distribution). Use to answer 'which publications/sources does ChatGPT or Perplexity cite for <category>' or 'where should a <category> brand earn coverage to be cited by AI'.

{'type': 'object', 'required': ['category', 'question_shape'], 'properties': {'limit': {'type': 'integer', 'default': 25, 'maximum': 100, 'minimum': 1}, 'offset': {'type': 'integer', 'default': 0, 'minimum': 0}, 'category': {'type': 'string', 'description': 'Category key, e.g. cybersecurity.'}, 'source_role': {'type': 'string', 'description': 'Optional filter, e.g. editorial_media for publications only, vendor_owned, analyst_research, community_social.'}, 'question_shape': {'enum': ['best_x', 'how_choose', 'is_x_worth', 'news_topic', 'problem_first', 'top_list', 'x_vs_y'], 'type': 'string', 'description': 'Buyer question pattern: best_x (best X tools), how_choose (how to choose), is_x_worth (is it worth it), news_topic (recent news), problem_first (how to solve a problem), top_list (top platforms), x_vs_y (A vs B).'}}, 'additionalProperties': False}
mri_get_domain
How often AI engines cite a site
For one domain or URL, return how often AI answer engines cite it: overall citation rate, which engines cite it, confidence tier, rank among all cited domains and within its source role, and per-category segment rates. Use to answer 'does ChatGPT/Perplexity cite <site>' or 'how authoritative is <publication> as an AI source'.

mri_list_categories
List MRI categories
List every Machine Relations Index category (e.g. cybersecurity, fintech, enterprise-software, ai-visibility-geo) with the question shapes that have published citation rates, plus the source-role vocabulary. Call this first to get a valid category key.
