## Description

Post a Chatter message to a Salesforce record's feed. Use **List Case Feed Items** to read a case feed, or **Create Case Comment** to add a case comment instead of a Chatter post. The message is built from segments - a plain string becomes text, and `{ "type": "Mention", "username": "jsmith" }` mentions a user. [See the documentation](https://developer.salesforce.com/docs/atlas.en-us.chatterapi.meta/chatterapi/quickreference_post_feed_item.htm)

| `subjectId` | `string` | Yes | The record that will parent the feed item. Options are loaded from the connected account. |
| `messageSegments` | `string[]` | Yes | Each message segment can be a text string, which will be treated as a segment of type: Text, or a message segment object such as { "type": "Mention", "username": "john" } |

## Run it

**MCP**

```ts
import { Client } from "@modelcontextprotocol/sdk/client/index.js"
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js"
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 accessToken = await pd.rawAccessToken

const transport = new StreamableHTTPClientTransport(
  new URL("https://remote.mcp.pipedream.net/v3"),
  {
    requestInit: {
      headers: {
        Authorization: `Bearer ${accessToken}`,

        "x-pd-app-slug": "salesforce_rest_api",
      },
    },
  },
)

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: "salesforce_rest_api-post-feed-to-chatter",
  arguments: {
    sobjectType: "SObject Type",
    subjectId: "Record ID",
  },
