API store
Zap v5 attaches catalog APIs through three API-store plugins instead of first-party adapters:apistore.context7— hosted docs/search MCP athttps://mcp.context7.com/mcp(CONTEXT7_API_KEY).apistore.open-connector— self-hosted connector MCP inside the VM athttp://127.0.0.1:3000/mcp(loopback only).apistore.composio— hosted MCP session minted by the control plane (entity = tenant id).


Each API-store plugin renders one MCP registration per harness config format (
yaml, json, json5, toml, cli), so every harness on a heavy runtime sees the same connectors.
Skills store
Skills follow the manifest contract: YAML frontmatter withname, description, version, and optional metadata.zap.{weight,lanes,harnesses}. In a runtime the store lives at /zap/skills/<name>/SKILL.md and is symlinked or copied into each harness’s skills directories at boot.
