# Candid

Connection integration for eve. Research nonprofits and funders using Candid's data.

## Install

Add the connection from eve's registry. This writes the initial definition under `agent/connections/` and installs its authentication dependency when needed:

```bash
eve add connection/candid
```

## Quick start

### MCP · User

Create `agent/connections/candid.ts`. The connection name is derived from the filename:

```ts
// agent/connections/candid.ts
import { connect } from "@vercel/connect/eve";
import { defineMcpClientConnection } from "eve/connections";

export default defineMcpClientConnection({
  url: "https://mcp.candid.org/mcp",
  description: "Candid: research nonprofits, funders, and grants.",
  auth: connect("candid"),
});
```

Connect owns the OAuth flow, and each end-user authorizes in their own browser before their first tool call.

## Configure

### MCP · User

Link your project, create the connector, and pull OIDC locally:

```bash
vercel link
vercel connect create candid
vercel env pull
```

See the [Connections docs](/docs/connections) for principal types, headers, approval, and protocol-specific filters.
