## Description

Create a new file or overwrite an existing one in a repository with a single commit. Provide the repository as an `owner/repo` string, the file `path`, the raw text `content` (passed as-is — do not base64-encode it yourself), and a commit message. If the file already exists on the target branch it is overwritten; the required blob SHA is resolved for you automatically. Defaults to the repository's default branch unless `branch` is set. [See the documentation](https://docs.github.com/en/rest/repos/contents#create-or-update-file-contents)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `repoFullname` | `string` | Yes | The repository in owner/repo format, for example PipedreamHQ/pipedream (not case sensitive). If you pass just a repository name with no owner (e.g. my-repo), the authenticated user is assumed as the owner — convenient for "my repo" requests. Do NOT repeat the repository name as the owner (e.g. my-repo/my-repo); if you don't know the owner, pass only the name or run List Repositories to find it. |
| `path` | `string` | Yes | The full path of the file, e.g. docs/notes.md. If the file already exists it will be overwritten. |
| `content` | `string` | Yes | The raw text contents of the file (plain text, not base64). If the file already exists, the entire file is overwritten with this content. |
| `message` | `string` | Yes | The commit message for this change. |
| `branch` | `string` | No | The branch to commit to, e.g. main. Defaults to the repository's default branch. |

## 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-project-id": process.env.PIPEDREAM_PROJECT_ID!,
        "x-pd-environment": "production",
        "x-pd-external-user-id": "{external_user_id}", // any stable ID for this user in your system
        "x-pd-app-slug": "github",
      },
    },
  },
)

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: "github-create-or-update-file-contents",
  arguments: {
    repoFullname: "Repository",
    path: "Path",
  },
})
```

**TypeScript**

  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const result = await pd.actions.run({
  id: "github-create-or-update-file-contents",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    github: { authProvisionId: "apn_xxxxxxx" },
