Both connectors declared `mcp_config: {command: "npx", args: ["-y", "<pkg>"]}`
and shipped no code at all. Skald treats a mcp_local `args[0]` as the *name of
the file to run*, not as an argument: install stores `script_path = "<id>/-y"`
and global_enable launches `npx /…/connectors/<id>/-y`, a path that does not
exist. The server never answered `initialize`, so start_server failed — and
since global_enable still returns 200 with an `error` in the body, the UI showed
the connector as enabled while `render_mcp_list` (built from the live runtime)
left it out of the agent's system context entirely.
Ship a two-file wrapper instead: a package.json pinning the upstream package
(mcp-fetch-server@1.1.2, firecrawl-mcp@3.23.7) and an index.js importing it for
its side effect, so `node index.js` is a real local_script and
ensure_installed_host installs the deps beside it. No node_modules, no lockfile.
Also: drop the legacy `launch_command` / top-level `transport` / `dependencies`
fields; drop firecrawl's inert `mcp_config.env` placeholder (same case as gmaps
— tokens are only substituted in the URL); add firecrawl_developer_search to
firecrawl's tools[] and API_KEY to its requires; realign manifest and fragment
versions to 5 / 1.1.0 (they were 2 vs 4, so no Update badge could ever appear).
Verified end-to-end against the shipped files by reproducing Skald's own path:
`npm ci || npm install --omit=dev` then `node <abs>/index.js` — initialize,
tools/list and a real tools/call, JSON-RPC only on stdout.
