Read contacts, projects, documents and log entries, and run read-only queries in HERO Software. For craftsman businesses that manage customers, projects and invoices in HERO Software. Hosted by usefulapi — connect from Claude, ChatGPT, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"hero-software": {
"url": "https://hero-software.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"hero-software": {
"type": "http",
"url": "https://hero-software.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
List the contacts with the category customer. Ask the assistant to show the number, name, email, phone and address of each one.
hero_list_contacts
List the projects with their trade, status and customer. Ask the assistant to show only the open ones and who the customer is.
hero_list_projects
Open one project to read its customer documents and its log book entries. Use it to prepare a call with the customer.
hero_get_project
List the customer documents with number, date, value, VAT and status. Ask the assistant to sum the invoices of one month.
hero_list_documents
Run a read-only GraphQL query, for example for calendar events or product versions. The server refuses mutations.
hero_run_query
The login page asks for your HERO API key.
HERO support issues the API key on request (see the HERO API documentation). The key is used only to call the HERO API on your behalf and to derive a private account id. It is never shown to anyone.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your HERO API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
Turn on the HERO Software connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
hero_list_contacts | read | List contacts List contacts (customers and others) with number, name, company, email, phone and address. Filter by category (for example 'customer'). Page with offset. HERO GraphQL query: contacts. |
hero_list_projects | read | List projects List projects with project number, trade (measure), customer, contact person, project address and status. Pass ids to fetch only some projects. HERO GraphQL query: project_matches. |
hero_get_project | read | Get a project with documents and log Get one project by id with its customer documents (type, number, value, file link) and its history entries (log book). HERO GraphQL query: project_matches(ids). |
hero_list_documents | read | List documents List customer documents (offers, invoices and so on) with number, date, value, VAT, status, document type and file link. HERO GraphQL query: customer_documents. |
hero_run_query | read | Run a read-only GraphQL query Run any read-only GraphQL query on the HERO API, for example calendar_events or supply_product_versions, or a schema introspection ({ __schema { queryType { fields { name } } } }). Mutations and subscriptions are refused. The schema is only visible by introspection with your key. |
hero_usage_status | Usage status (free-tier meter) Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter. | |
hero_request_feature | Request a missing feature Tell usefulapi that the user needs something the HERO Software tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. | |
hero_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on HERO Software (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $39/month or $390/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter. | |
hero_cancel_subscription | Cancel the Pro subscription Cancel the caller's HERO Software Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run hero_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this HERO Software server only. Subscribe with hero_upgrade (it returns a Stripe Checkout link). Cancel any time with hero_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running hero_upgrade before then undoes the cancel. Or write to [email protected].
List customers with their email and address. See which projects are open. Review a project with its documents and log. Check the offers and invoices. Read other data with a custom query. See what you can do for the details.
No. usefulapi is an independent service. It is not affiliated with or endorsed by HERO Software. The server calls the HERO Software API with your own HERO Software access, so it sees only the data that your account can see.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
The login page asks for your HERO API key. See Before you connect for where to find it.
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your HERO API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the HERO Software API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in HERO Software.
All 5 HERO Software tools are marked read-only.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls (fair use limit: 10,000 tool calls a month), for this HERO Software server only. Cancel any time: Pro then runs to the end of the paid period. Run hero_usage_status to see how many calls you used.
Ask the AI to run hero_upgrade: it returns a Stripe Checkout link. To cancel, run hero_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with hero_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
