Treat them as evidence to inspect, not a count of distinct defects. Back to [zenodo-mcp-server](/mcp/zenodo-mcp-server). ## Most discussed ### bug(zenodo_list_files): archive-mode notices cite a missing download_url and hide readable unlisted members ### Server version 0.1.0 ### mcp-ts-core version 0.13.6 ### Runtime Node ### Runtime version Node 26.5.0 ### Transport HTTP ### Description In archive mode (`archive_key` set), two `zenodo_list_files` notices send the agent somewhere the response doesn't support: 1. When Zenodo truncates the listing, the notice says to "download the archive from `download_url`", but the archive-mode output has no `download_url`. The `archive` object carries only `key`, `size`, `listed_members`,… [Read the thread](https://github.com/cyanheads/zenodo-mcp-server/issues/5) · 2026-09-24 · closed · 3 comments ### bug(zenodo_read_file): ZIP-member truncation notice says to download the archive when a larger max_bytes would do ### Server version 0.1.0 ### mcp-ts-core version 0.13.6 ### Runtime Node ### Runtime version Node 26.5.0 ### Transport HTTP ### Description When a `zenodo_read_file` ZIP-member read stops at `max_bytes`, the notice always says to download the whole archive, even when the member is smaller than the 65,536-byte cap. Calling again with a larger `max_bytes` would return the full member, but the notice doesn't say that. ### Steps to reproduce 1. `zenodo_read_file` `{ "id": "22705923",… [Read the thread](https://github.com/cyanheads/zenodo-mcp-server/issues/4) · 2026-09-24 · closed · 3 comments ### bug(zenodo_search_records): resource_type rejects the type::id search_value lookup returns ### Server version 0.1.0 ### mcp-ts-core version 0.13.6 ### Runtime Node ### Runtime version Node 26.5.0 ### Transport HTTP ### Description `zenodo_lookup_vocabulary` (resource_types) prints each entry's `search_value` in `::` form, which is Zenodo's own spelling of a subtype. `zenodo_search_records` rejects that exact value as `resource_type`, with the message `Missing required field`, which reads as if the parameter were absent. `publication::publication-article` maps to… [Read the thread](https://github.com/cyanheads/zenodo-mcp-server/issues/3) · 2026-09-24 · closed · 3 comments ### feat(zenodo_read_file): sniff extensionless octet-stream files instead of refusing them ### Use case `zenodo_read_file` decides from the MIME type and extension alone whether a file is text, and it does so before fetching anything. Files like `LICENSE`, `COPYING`, `Makefile`, `Dockerfile`, and `README` arrive from Zenodo as `application/octet-stream` with no extension, so they come back `not_text` with no content. They are among the files an agent most often needs to read in a software deposit. ### Proposed behavior For `application/octet-stream` (or no MIME type) with an… [Read the thread](https://github.com/cyanheads/zenodo-mcp-server/issues/8) · 2026-09-24 · closed · 2 comments ### bug(identifiers): wrapped id with trailing punctuation is rejected as invalid_identifier ### Server version 0.1.0 ### mcp-ts-core version 0.13.6 ### Runtime Node ### Runtime version Node 26.5.0 ### Transport HTTP ### Description `parseRecordRef` strips wrapping `<…>` before it removes trailing punctuation. An id that has both, such as a DOI copied out of a sentence like `…available at .`, is rejected as `invalid_identifier`. Each form works on its own. ### Steps to reproduce `zenodo_get_record` with each `id`: | id | result | |:--|:--| |… [Read the thread](https://github.com/cyanheads/zenodo-mcp-server/issues/6) · 2026-09-24 · closed · 2 comments ### bug(zenodo_search_records): facet counts ignore resource_type, file_type, and access_status filters ### Server version 0.1.0 ### mcp-ts-core version 0.13.6 ### Runtime Node ### Runtime version Node 26.5.0 ### Transport HTTP ### Description The `zenodo_search_records` description and `facets` schema say facet counts cover "the full match set", but `resource_type`, `file_type`, and `access_status` do not narrow them. Zenodo applies those three as post-filters, so the aggregations are computed before they apply. The counts then contradict `total`, and an agent reading `file_type: csv… [Read the thread](https://github.com/cyanheads/zenodo-mcp-server/issues/2) · 2026-09-24 · closed · 2 comments ### bug(zenodo_list_versions): page past the 10,000 window returns a raw upstream 400 ### Server version 0.1.0 ### mcp-ts-core version 0.13.6 ### Runtime Node ### Runtime version Node 26.5.0 ### Transport HTTP ### Description `zenodo_list_versions` sends any `page` straight upstream. When `page × size` exceeds 10,000, Zenodo answers HTTP 400 and the tool surfaces the raw upstream error with no `reason` and no recovery. `zenodo_search_records` and `zenodo_lookup_vocabulary` both pre-validate the same window and return a typed `result_window_exceeded`. ### Steps to… [Read the thread](https://github.com/cyanheads/zenodo-mcp-server/issues/1) · 2026-09-24 · closed · 2 comments ## Most recent The remaining reports are on [the project's issue tracker](https://github.com/cyanheads/zenodo-mcp-server/issues).
