mTOR Atlas MCP server

Read-only access to Oliver's mTOR Atlas for AI assistants that speak the Model Context Protocol: curated mTOR studies labelled by the kind of study behind them, entities (genes, complexes, drugs, diseases, processes), signed pathway relations with their supporting and conflicting evidence, and the Atlas's open questions.

The server reads the Atlas's public static API (https://mtor-atlas.org/api/v1/, documented at mtor-atlas.org/api). No key, no account. Data is CC BY 4.0.

Tools

| Tool | What it answers | |---|---| | atlas_about | Dataset version, corpus snapshot, counts, evidence codes, how to cite; contested and conflicting relation counts (derived_counts only when the Atlas does not report them) | | search_studies | Studies by keywords, evidence code, linked entity, year. Also finds a study by PMID or DOI, by a synonym of a linked entity ("sirolimus"), by an author's full name ("Claudio De Virgilio") and by words from the abstract excerpt | | get_study | One study (by Atlas ID, PMID, DOI or PMCID) with its entities, relations and open questions | | search_authors / get_author | People: profiled authors by full name, author-list form, ORCID or lab, with their studies; plus matching names in author lists without a profile | | search_entities / get_entity | Genes, drugs, diseases… with their studies and relations. Each hit says where it matched (match_field); match="name" skips description-only hits | | find_relations / get_relation | Pathway claims ("Rheb activates mTORC1") with mechanism, boundary conditions and confidence | | evidence_between | "What is the evidence that A acts on B?" with both supporting and conflicting studies | | find_contradictions | Contested claims, with both sides of the evidence. Paged (offset), status and breakdown explain the total, only_contested, brief | | list_questions / get_question | Open evidence gaps and testable hypotheses. list_questions takes an optional query, is paged and shortens still_open unless brief=false; get_question has the full text |

Answer size

Long text and repeated records are kept short by default. list_questions cuts still_open at a sentence boundary and sets still_open_truncated; find_contradictions and evidence_between send a study in full the first time it appears in an answer and afterwards as a short card (sid, title, evidence code with its label, url) with full_card_in. Pass brief=false or dedupe=false to get everything. Every list tool takes limit and offset; pass next_offset back as offset for the next page.

Reading the evidence codes

S synthesis of human data · H human study · A animal model · M molecular / in vitro · R review · PP preprint · RT registered trial. The code describes the kind of study, not its quality. Every record the server returns repeats this, so a code never travels without its meaning.

"Not in the Atlas" means not in this curated corpus. It does not mean the relationship is unknown.

Configuration

ATLAS_API_BASE (optional) points the server at another copy of the API, for example a local build: ATLAS_API_BASE=/path/to/dist/api/v1.
