resolve

Read-only

Fetch a complete DataResource by known ID—including its files manifest and optional citation, retraction status, FAIR score, licence advisory, or provenance dossier—to inspect or reuse a dataset.

Instructions

Tool names in this text are this server's own; your client may list them with a prefix (in Claude Code, mcp__data-aggregator__resolve): call the name it lists. Fetch the full DataResource for a known id (e.g. 'zenodo:1254563', 'datacite:10.5061/dryad.t4b8gtjgj', 'hf:davidcechak/Arabidopsis_thaliana_DNA_v0', a bare Zenodo record id, or a DOI), including the complete files[] manifest. Publication resolve also attaches normalized identifiers (pmid/pmcid/doi) and, when open access, a full-text file. Pass cite= to render a citation onto the result (citation field); omitted means no citation. Pass trust=true to attach retraction status (via Crossref) under trust{}. Pass fair=true to attach an RDA-grounded FAIRness score (0–100 + F/A/I/R sub-scores + actionable gaps) computed from the record under fair{}. Pass use= (commercial/redistribute/modify/ml-training) to attach a licence-compatibility advisory (ALLOW/REVIEW/DENY, not legal advice) under license_compat{}. Pass format=provenance for a one-call RO-Crate 1.1 data-availability dossier (under provenance{}) composing version-currency, licence+SPDX, FAIR score, retraction status, and the source/DOI/ID chain — it auto-attaches fair + trust.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Input Schema

NameRequiredDescriptionDefault
idYesSource-prefixed id, bare Zenodo id, or DOI
useNoWhen set, attach a licence-compatibility advisory under license_compat{} for an intended use of the record. Supported intents: 'commercial', 'redistribute', 'modify', 'ml-training' (training = a derivative+commercial use, our stated interpretation). The verdict is ALLOW/REVIEW/DENY computed from a bundled choosealicense.com licence matrix keyed on the normalized SPDX id, naming the governing clause — a metadata-derived advisory, NOT legal advice. An unrecognized or absent licence yields REVIEW (never a fabricated ALLOW/DENY); an unknown intent is an error.
citeNoOptional citation format to render onto the result: 'bibtex', 'ris', 'csl-json', or any CSL style name ('apa', 'mla', 'vancouver', ...). DOI-bearing records render via DOI content negotiation; non-DOI records support 'csl-json' only. Omitted = no citation. Failures degrade quietly (citation stays null).
fairNoWhen true, attach an RDA-grounded FAIRness assessment under fair{}: a 0–100 overall score plus findable/accessible/interoperable/reusable sub-scores, the count of indicators evaluated, and actionable gaps each naming its RDA FAIR Data Maturity Model indicator id. Pure/local — no network call. Only the machine-evaluable subset is scored (never fabricates what the metadata cannot show).
trustNoWhen true, attach trust signals (retraction status via Crossref) to the result under trust{}. One extra Crossref call; only meaningful for DOI-bearing records (a DataCite data DOI Crossref does not register leaves retracted=null = unknown, never a false clean claim).
formatNoOptional export to render onto the result. 'croissant' attaches a file-level Croissant JSON-LD manifest (croissant field); 'ro-crate' attaches a minimal RO-Crate 1.1 manifest (ro_crate field); 'provenance' attaches a one-call RO-Crate 1.1 data-availability dossier (provenance field) bundling version-currency, licence+SPDX, FAIR score, retraction status, and the source/DOI/ID chain — it auto-attaches fair{} and trust{} so the dossier is complete in one call (unknown signals are reported as unknown, never as a clean claim).

TDQS

A4.6/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Goes well past readOnlyHint=true, disclosing that trust adds a Crossref network call, that trust is only meaningful for DOI-bearing records leaving retracted=null rather than a false clean claim, that citation failures degrade quietly, and that provenance auto-attaches fair+trust. These are the kind of side-effect and failure-mode details annotations cannot convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Core purpose is front-loaded before the per-flag detail, and dense phrasing packs real information into each sentence. The opening client-prefix note is server-level meta rather than tool behavior, slightly diluting focus at the top.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read tool with an output schema, a full set of optional-flag behaviors, and explicit readOnlyHint, nothing needed to invoke it correctly is missing; the description covers id forms, each flag's effect, and fallback behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and the schema descriptions are already detailed, so the baseline is 3. The description still adds value by giving concrete id examples and clarifying the coupling between format=provenance and the auto-attached fair/trust signals.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (Fetch) and resource (full DataResource), scoped to 'a known id', and enumerates concrete id formats (zenodo:..., DOI, bare record id). An agent can tell this is a look-up-by-identifier, distinct from a search-by-query.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

'For a known id' establishes the precondition to use this tool, and the optional-flag behaviors are spelled out. It never names the sibling `fetch` or `search` to route the agent explicitly, so the boundary with fetch in particular is left to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
