The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
igvf_portal_searchSearch the IGVF Data Portal.
igvf_portal_get_by_idRetrieve a single IGVF item by its @id, accession, or UUID.
igvf_portal_get_schemaReturn the JSON schema for an IGVF item type.
igvf_portal_list_item_typesReturn a sorted list of all valid IGVF item type names.
igvf_portal_get_collectionList items from a specific IGVF collection endpoint.
igvf_portal_get_endpoint_paramsReturn the available filter parameters for a collection or endpoint.
igvf_portal_downloadDownload an IGVF file directly to a local path.
igvf_portal_batch_downloadGet download URLs for files belonging to matching FileSet items and save them to a file.
igvf_portal_facetsGet aggregated facet counts for an IGVF item type.
igvf_portal_reportGenerate a TSV-formatted report for an item type and save it to a file.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
10/10 tools missing one or more hints — igvf_portal_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); igvf_portal_get_by_id (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); igvf_portal_get_schema (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +7 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Descriptions match behaviour
1 tool describes read intent but its handler mutates — igvf_portal_batch_download (line 382: with open(save_path, "wb") as f:)
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
9/10 tool handlers declare input schemas (90%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/10 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests exist
No test files found
Add tests that exercise each declared tool.
Tool description accuracy
igvf_portal_batch_download: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
