Search, read, create and update Vtiger CRM leads, contacts, deals, cases and more; tag records. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the Vtiger connector, then ask in plain words. The AI picks the tools.
For sales and support teams that work in Vtiger CRM on Vtiger Cloud.
The AI reads the module's fields and picklist values, then lists and counts leads filtered by fields such as rating, source or owner.
The AI finds contacts, leads or organizations by an exact email address or phone number and opens the full record.
The AI checks the module's fields, then runs read-only SELECT queries on it, for example deals by stage or open cases of an organization, up to 100 records per call.
The AI checks the mandatory fields, creates the lead assigned to you, and tags it, for example with the name of an event.
Changes dataThe AI opens the record, then changes only the fields you name, such as a deal's stage or a case's status, and leaves the rest as it is. Nothing is deleted.
Changes dataThe login page asks for your Vtiger CRM address, Username and Access Key.
The address is the one in your browser when you use the CRM, for example acme.od2.vtiger.com (Vtiger Cloud). In the CRM open your profile menu → My Preferences and copy the Access Key. The key acts with that user's permissions and record visibility. Your credentials are used only to call the Vtiger API on your behalf; they are never shown to anyone.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"vtiger": {
"url": "https://vtiger.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"vtiger": {
"type": "http",
"url": "https://vtiger.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
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 Vtiger CRM address, Username and Access 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.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper account | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per account | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this Vtiger server only. Ask your AI to run vtiger_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with vtiger_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with vtiger_upgrade before then undoes the cancel. Or write to [email protected].

No. usefulapi is an independent service. It is not affiliated with or endorsed by Vtiger. The server calls the Vtiger API with your own Vtiger 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 Vtiger CRM address, Username and Access Key. See Before you connect for where to find them.
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 Vtiger CRM address, Username and Access 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 Vtiger 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 Vtiger.
Yes, if you approve it. 3 of the 13 Vtiger tools can create or change data. The other 10 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Vtiger server only. Cancel any time: your paid plan then runs to the end of the paid period. Run vtiger_usage_status to see how many calls you used.
Ask the AI to run vtiger_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run vtiger_cancel_subscription. Your paid plan continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with vtiger_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.
