Research intelligence, FRED macroeconomic observations, and normalized SEC company financials for Claude Code and Codex. Version 2.0.0 uses OAuth and one shared set of skills.
Service: expert-system.starmode.dev · Support · Privacy · Terms
| Skill | Example | Workflow |
|---|---|---|
| Research | “What are experts saying about AI infrastructure?” | Search previews → selected takeaways → bounded source verification |
| Macro | “Show recent US inflation and unemployment.” | Resolve supported FRED series → retrieve dated observations |
| Financials | “Compare Apple's revenue and operating cash flow.” | Discover metrics → retrieve company series with filing provenance |
Results preserve source links, observation dates, units, and fiscal-period semantics. These capabilities do not provide live stock prices, forecasts, or trading. There are 11 data tools; the server also offers a free get_profile identity utility. Data calls share the account's REST quota, including valid calls that return empty or partial results.
Once v2 is available on the repository's default branch, run:
/plugin marketplace add starmode-base/expert-system-plugin
/plugin install expert-system@expert-system
Restart Claude Code, open /mcp, and follow the Expert System sign-in flow. Approve the OAuth read access and any client tool-permission prompts you intend to allow. No API key is required. Use natural-language requests or /expert-system:research, /expert-system:macro, and /expert-system:financials.
For local development before publication: claude --plugin-dir /absolute/path/to/expert-system-plugin. For isolated install testing and GitHub branch validation, see the release checklist.
Update with /plugin marketplace update expert-system then /plugin update expert-system@expert-system. Remove with /plugin uninstall expert-system@expert-system. Manage sign-in separately in /mcp; uninstalling a plugin does not delete your service account or billing subscription.
Register the repository marketplace and install the plugin using a Codex CLI with plugin support:
codex plugin marketplace add starmode-base/expert-system-plugin --ref main
codex plugin add expert-system@expert-systemAlternatively, select that marketplace in the Codex Plugins UI and install Expert System. Complete its OAuth sign-in prompt, then start a new task so the skills and connection are loaded. Ask naturally or select the research, macro, or financials skill. The three summaries support routing; the host discovers tool schemas as needed rather than this plugin eagerly loading them. For a release candidate, replace main with the candidate tag in the marketplace command.
To update, refresh the marketplace with codex plugin marketplace upgrade expert-system and reinstall from the Plugins UI (or remove/add using the CLI). Start a new task. Remove with codex plugin remove expert-system@expert-system; remove an unused marketplace with codex plugin marketplace remove expert-system.
The shared MCP endpoint is https://expert-system.starmode.dev/api/mcp. Sign in through the client's connection controls; credentials belong to the client, never plugin files or prompts. The server requests expert-system:read. Cancelling sign-in leaves the connection unavailable; retry when ready. An expired or revoked session may require reconnecting. For access denied, verify your account and authorization rather than repeatedly retrying tools.
In Claude Code use /mcp; in Codex inspect /mcp and the plugin's connection settings. If tools are missing, confirm installation, enable the plugin, reconnect, and start a fresh task. Remove duplicate manually configured Expert System connections if they cause duplicate tools. A quota error requires waiting for renewal or managing your plan, not reinstalling. Report client version and redacted error details through Support; never post tokens or personal data.
For a v1 upgrade, uninstall the old plugin, remove its saved plugin API-key configuration, then install v2 and sign in. Existing REST /api/v1 integrations continue to use their API keys; revoke an old key only if it is no longer used elsewhere.
The root plugin.json and mcp.json follow the portable Agent Plugins format. .claude-plugin/ and .codex-plugin/ provide client compatibility; .agents/plugins/marketplace.json makes the repository installable as a Codex marketplace. Both clients use the same skills/. Skill MCP dependencies follow OpenAI's skill guidance. The server repository hosts public/marketplace.json as a compatibility copy of this repository’s canonical Claude marketplace. Privacy and terms pages are also hosted by the server.

It excludes application code, environment files, local config, and dependencies. Installation from GitHub still checks out the repository; never commit credentials. Release, clean-profile validation, routing scenarios, monitoring, and rollback are documented in the release checklist.
The plugin checks run without a server checkout. Before release, additionally verify the 11-tool contract, hosted marketplace copy, and policy files against the server:
