IMPLEMENTATION
Call this tool
Connect a user's PostHog account once, then configure and run Capture Event from your backend or agent.
import { PipedreamClient } from "@pipedream/sdk"
const pd = new PipedreamClient({
projectId: process.env.PIPEDREAM_PROJECT_ID!,
clientId: process.env.PIPEDREAM_CLIENT_ID!,
clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
projectEnvironment: "production",
})
const result = await pd.actions.run({
id: "posthog-capture-event",
externalUserId: "{external_user_id}", // any stable ID for this user in your system
configuredProps: {
posthog: { authProvisionId: "apn_xxxxxxx" },
projectApiKey: "Project API Key",
organizationId: "Organization ID",
},
})
console.log(result)curl -X POST https://api.pipedream.com/v1/connect/{project_id}/actions/run \

-H "X-PD-Environment: production" \
-H "Authorization: Bearer {access_token}" \

const transport = new StreamableHTTPClientTransport(
new URL("https://remote.mcp.pipedream.net/v3"),
{
requestInit: {

},
)
const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)
const { tools } = await mcp.listTools()
// listTools() hands your model this tool's input schema, so it can
// fill the arguments itself:
const result = await mcp.callTool({
name: "posthog-capture-event",
arguments: {
projectApiKey: "Project API Key",
organizationId: "Organization ID",
},
})SCHEMA
Inputs
Pipedream supplies the connected account. Your application provides the operation-specific values below. Dynamic inputs are resolved against that user's account.
| Property | Type | Description |
|---|---|---|
projectApiKey Project API Key | string | The Project API Key in your Project Settings. This key can only create new events. It can't read events or any of your other data stored with PostHog, so it's safe to use in public apps. Required |
organizationId Organization ID | string | Identifier of an organization Required Dynamic |
projectId Project ID | string | Identifier of a project Required Dynamic |
event Event | string | The event type to capture Required Dynamic |
properties Properties | object | The properties to include in the event Optional |

Tool details
Behavior hints are published with the component in the Pipedream registry and surface as MCP tool annotations, so an agent can reason about a tool before it calls it.
