Connect an assistant

One address. Works in any MCP client.

Incumbently runs a remote MCP server with OAuth. Add the address, sign in, and allow access. Claude, ChatGPT and Cursor come with Pro and Max.

Server address

https://app.incumbently.com/mcp

Claude

Open Settings, then Connectors.
Choose Add custom connector and paste the address.
Sign in to Incumbently and allow access.

ChatGPT

Open Settings, then Apps and Connectors.
Create a connector with the address.
Sign in to Incumbently and allow access.

Cursor

Add the server to .cursor/mcp.json.
Reload Cursor, then sign in when asked.

.cursor/mcp.json

{
  "mcpServers": {
    "incumbently": {
      "url": "https://app.incumbently.com/mcp"
    }
  }
}

Other clients work the same way: add the address as a remote server, then sign in when the client opens the browser.

API

The same data, in your code.

Create a key in the dashboard under Claude and API. Send it as a Bearer token. Every response is JSON.

Base URL

https://app.incumbently.com/v1

Endpoint	Returns	Credits
`GET /v1/me`	Your plan and the credits you have left	Free
`GET /v1/tools?search=zendesk`	Find a tool in the catalogue	Free

`GET /v1/tools/:tool/companies`	Companies using a tool. Filters: country, size, industry	1 per company
`GET /v1/tools/:tool/changes`	Adoptions and drops. Filters: kind (adopted or dropped), since, size, country	1 per change

Example

curl "https://app.incumbently.com/v1/tools/zendesk/changes?kind=dropped&since=2026-10-01" \
  -H "Authorization: Bearer YOUR_KEY"

One credit returns one company record. Pages hold up to 100 records; pass page=2 for more. Each response carries X-Credits-Charged and X-Credits-Remaining. Each key can make 60 requests a minute.

Status	Code	Meaning
401	`unauthorized`	The key is missing, wrong or revoked.
403	`plan_required`	The API comes with Pro and Max.
402	`insufficient_credits`	You've used this month's credits.
429	`rate_limited`	More than 60 requests a minute on one key.
404	`not_found`	No tool or endpoint by that name.
400	`bad_request`	A filter has the wrong format, like a date that isn't YYYY-MM-DD.
503	`unavailable`	Data is briefly unavailable. Try again in a minute.

Errors look like {"error": {"code": "…", "message": "…"}}.

Alerts

Know when accounts change.

Free

A monthly email report of who started or stopped using your tool

Pro

A daily email digest of new changes across your tools

Max

Real-time email
A post to Slack or any webhook URL

Set alerts in the dashboard under Settings, then Alerts. Webhooks get a JSON post with a ready-to-read summary and the changes:

Webhook body

{
  "text": "Incumbently: 2 new changes\nDropped Zendesk: Acme (acme.com)\nAdopted Intercom: Acme (acme.com)",
  "changes": [
    { "tool": "Zendesk", "company": "Acme", "domain": "acme.com", "kind": "Dropped", "when": "Nov 6" }
  ]
}

A Slack incoming-webhook URL works as is, because Slack shows the text field.
