Summary

Adds scigantic-catalog, a third-party prompt agent for public dataset discovery. It reaches
the Scigantic catalog of several thousand curated open scientific archives through the anonymous,
read-only Scigantic MCP server (https://api.scigantic.com/mcp): catalog search, schema cards,
loader snippets, arXiv-to-dataset lookup and SureChEMBL patent chemistry. No containerized
tools, no API key. The MCP connection is registered in Foundry following the same pattern as
wiley-nexus; mcp/README.md documents it.

Type of change

• New agent (under agents/<name>/)

Related issue / tracking

n/a

Schema impact

• No schema changes

Validation checklist

• Documentation (README.md, schemas) is updated to match the change.
• No hand-edits to .auto-registry/** (it is generated post-merge).
• No OS / editor artefacts committed.
• No model-weight files added.
• No secrets, customer data, or internal-only URLs are committed.
• All Markdown links resolve.

Reviewer notes (optional)

metadata.yaml and agent.yaml validate against metadata-schema.json and agent-schema-v2.json.
The tool names and parameters in the instructions were taken from a live tools/list call against
the endpoint. The endpoint needs no credential; the walkthrough covers the case where the Foundry
dialog requires one anyway.
