Sniff MCP server

Sniff is a remote MCP server that gives an AI agent 18 tools, among them ask, ask_the_graph, ask_variant_context. It answers at https://mcp.sniff.world/mcp/ over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 12 September 2026; the last check, on 24 October 2026, succeeded.

Canine genomics for agents: breed allele frequencies, AI pathogenicity + OMIA clinical disease layer

Description as the publisher wrote it.

The 18 tools Sniff offers

Tool	What it does
`ask`	Ask Sniff a natural-language canine-genetics question and get a GROUNDED, CITED answer (or an honest abstain). Covers inherited diseases (OMIA) and their human homologs (the dog<->human disease bridge), breed disease/carrier risk, variant p Inputs: question
`ask_the_graph`	THE INSTRUMENT — ask a free-form CROSS-SPECIES genetics question and get FILTERED, HONEST HINTS (never a confident guess). It compiles your question into a typed query plan over the dog<->human edge-graph, runs it deterministically, and sco Inputs: question, narrate
`ask_variant_context`	THE headline query. Given a CanFam4 position (e.g. '5:56189113'), return the variant's global + popmax frequency, breed-stratified cross-breed frequencies, ESM2/Pangolin/phyloP pathogenicity, gene context, linked diseases (v1.1), provenance Inputs: position, breed_context, top_n, cross_breed_full
`breed_similarity`	Genetic distance between two breeds (top-10-PC Euclidean). Lower = more genetically similar. Inputs: breed_a, breed_b
`breed_summary`	Breed profile: top damaging common variants (ESM2<=-5 & breed AF>=5%), n_dogs, breed group. Descriptive only — not a health ranking. Inputs: breed
`breed_variant_frequency`	Breed-stratified allele frequency. Give a breed (e.g. 'bernese_mountain_dog') plus either a variant position or a gene symbol. Returns AF (+ rank) for the variant, or per-variant AFs in the gene. Inputs: breed, variant, gene
`breeds_in_atlas`	List all 188 breeds with breed-stratified frequencies in the atlas.
`disease_bridge`	The fused OMIA disease layer as cited atoms. Give a `disease` (name or 'OMIA:001870-9615') for its genes, inheritance, human homolog (OMIM/Mondo bridge), and variant pathogenicity grade (AVCG, ACMG/AMP 5-tier, curated in OMIA) when graded. Inputs: disease, breed
`disease_links`	A canine inherited disease (name or OMIA id) -> its governed OMIA clinical record: mode of inheritance, causal gene(s), curated description (summary / clinical features / molecular genetics / pathology / prevalence), clinical signs as HP/MP Inputs: disease
`disease_lookup`	Look up a canine inherited disease by name or OMIA id -> its governed OMIA clinical record (inheritance, causal gene(s), curated description, clinical signs, human OMIM analog + Mondo id, evidence base). Sourced to OMIA (CC-BY); returns a c Inputs: query
`gene_summary`	Variants in a gene (by gene symbol), ranked by impact then ESM2 damage. Paginated (limit, default 25); returns total_variants. Use af_min to filter by global AF. Inputs: gene_symbol, af_min, limit
`genes_indexed`	Top genes by number of variants in the atlas (discovery aid). Inputs: limit
`metadata`	Atlas metadata: release, DOI, assembly, variant/breed counts, scope banner, and the RPC catalog.
`nearest_breeds`	Genetically nearest breeds to the given breed (top-10-PC Euclidean in canine genetic space). Answers 'what breeds are most genetically similar to X?' via the PCA-256 breed co-embedding. Inputs: breed, k
`search_diseases`	Search the canine disease catalogue by free text -> ranked candidates [{omia_id, disease, url, score}]. Use before disease_lookup when the exact name is unknown. Dog-only. Inputs: query, limit
`semantic_search`	Faceted hybrid + semantic-ranker search over the whole knowledge base (diseases, breeds, Scout discoveries). Use for fuzzy/thematic intent ('drug sensitivity in herding dogs', 'breeds prone to eye disease', 'genetically diverse breeds'). en Inputs: query, top_k, entity_type, filters
`variant_lookup`	Single-variant lookup by CanFam4 position: ref/alt, global + popmax AF, consequence, gene, ESM2/Pangolin/phyloP, deleteriousness tier, canonical URL, provenance. Inputs: position
`variant_search`	Filtered discovery over all 9.67M variants. Predicates (combine freely): esm_max (ESM2 LLR <=), phylop_min (phyloP >=), popmax_min (popmax AF >=), gene_in (list of gene symbols), consequence, impact (HIGH/MODERATE/LOW/MODIFIER). Returns tot Inputs: esm_max, phylop_min, popmax_min, gene_in, consequence, impact

Questions about Sniff

Is there an official Sniff MCP server?

Yes. It is published by sniff.world and served from mcp.sniff.world, the vendor's own domain: https://mcp.sniff.world/mcp/.

How many tools does Sniff have?

18, as returned by the server's own tools/list on 23 September 2026: ask, ask_the_graph, ask_variant_context, breed_similarity, breed_summary, breed_variant_frequency, breeds_in_atlas, disease_bridge, and 10 more.

Is Sniff down?

It answered our last check on 24 October 2026 in 1171 ms. Over 6 checks since 12 September 2026 it answered 6.

How do I add Sniff to Cursor?

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.sniff.world/mcp/. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.

Does Sniff need an API key?

It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

Where this comes from

Publisher: world.sniff. Endpoint host: mcp.sniff.world. ARD identifier: urn:air:world.sniff:mcp:sniff-mcp. First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page is inferred from its name. Ranking in Neuronto search is never for sale.
