Plugin 0.4.0 moves the bundled arkiv MCP connection to General at https://mcp.arkiv.network/. The Devfolio event has ended, and General is the profile for building on Arkiv; event profiles are added separately when an event needs one.

Breaking changes

  • The connection moves from https://mcp.arkiv.network/devfolio to https://mcp.arkiv.network/. It keeps the name arkiv.
  • Devfolio-only tools and prompts are not on General: check_schema, check_submission, design_entity_model, prepare_devfolio and pillar_fit. For entity design use the model_entities workflow or, for a PostgreSQL schema, generate_entity_model. To keep working on a Devfolio project, add https://mcp.arkiv.network/devfolio as a second server; the README shows the commands.
  • Devfolio resources (devfolio/*, sdk-devfolio/*, guides/devfolio-current) are served only on /devfolio.
  • verify_entity and verify_tx are available on General.

Other changes

  • Claude Code sends X-Arkiv-Audience: internal only when ARKIV_AUDIENCE=internal is set, for Arkiv's own machines. Default headers are unchanged. Codex CLI sends no audience header (its plugin format accepts only static headers).
  • Bundled skills are unchanged at Arkiv-Network/skills@cd8bb37. Its arkiv-mcp skill still describes the previous event target; check server_status, which reports profile general.

Evidence

  • Linux ARM64: build, check and three full test-suite runs on the release commit, 0 failures. Windows: build, check, strict validation, and the suite with native installation tests (loopback only).
  • Real-host plugin journeys against the General build that went to production: Claude Code 28/28, Codex CLI 25/25.
  • Public installation from main in new isolated profiles: the installed Claude and Codex packages match the repository byte for byte, and both point to https://mcp.arkiv.network/.

Upgrade

  • Claude Code: claude plugin marketplace update arkiv, then claude plugin update arkiv@arkiv, and restart.
  • Codex CLI: codex plugin marketplace upgrade arkiv, then codex plugin add arkiv@arkiv, and start a new session. If Codex has not trusted the Arkiv hook, run /hooks inside Codex CLI.
