# PostProxy MCP Server
MCP (Model Context Protocol) server for integrating [PostProxy](https://postproxy.dev/) API with Claude Code. This server provides tools for publishing posts, checking statuses, and managing social media profiles through Claude Code.
## Installation
### Global Installation
```bash
npm install -g postproxy-mcp
```
### Local Installation
```bash
npm install postproxy-mcp
```
Claude Code stores MCP server configuration under `~/.claude/plugins/`.
After installing postproxy-mcp, Claude will automatically detect the server on restart.
## Configuration
### Register MCP Server
After installing postproxy-mcp, register it with Claude Code using the `claude mcp add` command:
```bash
claude mcp add --transport stdio postproxy-mcp --env POSTPROXY_API_KEY=your-api-key --env POSTPROXY_BASE_URL=https://api.postproxy.dev/api -- postproxy-mcp
```
Replace `your-api-key` with your actual PostProxy API key.
The configuration will be automatically saved to `~/.claude/plugins/`. After running this command:
1. Restart your Claude Code session
2. Test the connection by asking Claude: "Check my PostProxy authentication status"
3. If tools are available, Claude will be able to use them automatically
### Alternative: Interactive Setup
For non-technical users, you can use the interactive setup command:
```bash
postproxy-mcp setup
```
or
```bash
postproxy-mcp-setup
```
This will guide you through the setup process step by step and register the server using `claude mcp add` automatically.
## Available Tools
### Authentication Tools
#### `auth_status`
Check authentication status, API configuration, and workspace information.
**Parameters**: None
**Returns**:
```json
{
"authenticated": true,
"base_url": "https://api.postproxy.dev/api",
"profile_groups_count": 2
}
```
### Profile Management
#### `profile_groups_list`
List all profile groups accessible with your API key. Profile groups are organizational containers (e.g. per brand or client) that hold related profiles. Use a group's `id` to filter `profiles_list` by `profile_group_id`.
**Parameters**: None
**Returns**:
```json
{
"profile_groups": [
{
"id": "grp123abc",
"name": "Main Brand",
"profiles_count": 4
}
]
}
```
#### `profiles_list`
List all available social media profiles for posting.
**Parameters**:
- `profile_group_id` (string, optional): If provided, only profiles in this group are returned (use `profile_groups_list` to find group IDs)
**Returns**:
```json
{
"profiles": [
{
"id": "profile-123",
"name": "My Twitter Account",
"platform": "twitter",
"profile_group_id": "group-abc"
}
]
}
```
#### `profiles_placements`
List available placements for a profile. For Facebook profiles, placements are business pages. For LinkedIn profiles, placements include the personal profile and organizations. For Pinterest profiles, placements are boards. For Telegram profiles, placements are channels the bot can post to. Available for `facebook`, `linkedin`, `pinterest`, and `telegram` profiles.
**Parameters**:
- `profile_id` (string, required): Profile hashid
**Returns** (LinkedIn example):
```json
{
"placements": [
{
"id": null,
"name": "Personal Profile"
},
{
"id": "108520199",
"name": "Acme Marketing"
}
]
}
```
**Notes**:
- If no placement is specified when creating a post:
- **LinkedIn**: defaults to the personal profile
- **Facebook**: defaults to a random connected page (if only one page is connected, no need to set a placement ID)
- **Pinterest**: it fails
- **Telegram**: it fails — `chat_id` is required on every post
#### `profiles_stats`
Get the follower/engagement timeseries for a profile. Snapshots are captured roughly every 23 hours, so you can plot follower growth and other trends over time. The `stats` fields are platform-native (not normalized) — see [Stats Fields by Platform](#stats-fields-by-platform) in the `post_stats` section for shape and add-on profile-level keys (`followers_count`, `followersCount`, etc.) per network.
**Parameters**:
- `profile_id` (string, required): Profile hashid
- `placement_id` (string, conditional): **Required** for `facebook`, `linkedin`, and `telegram` profiles. Get it from `profiles_placements`. Omit for `instagram`, `threads`, `youtube`, `twitter`, `tiktok`, `pinterest`, and `bluesky`.
- `from` (string, optional): ISO 8601 timestamp — only include snapshots recorded at or after this time
- `to` (string, optional): ISO 8601 timestamp — only include snapshots recorded at or before this time
**Returns** (LinkedIn example):
```json
{
"data": {
"profile_id": "prof_li_001",
"platform": "linkedin",
"placement_id": "108520199",
"records": [
{ "stats": { "followerCount": 4500, "shareCount": 8, "likeCount": 80 }, "recorded_at": "2026-05-09T08:00:00Z" },
{ "stats": { "followerCount": 4520, "shareCount": 9, "likeCount": 90 }, "recorded_at": "2026-05-10T08:00:00Z" }
]
}
}
```
For non-placement networks (e.g. Bluesky), omit `placement_id`:
```json
{
"data": {
"profile_id": "prof_bsky_001",
"platform": "bluesky",
"placement_id": null,
"records": [
{ "stats": { "followersCount": 8800, "postsCount": 40 }, "recorded_at": "2026-05-09T08:00:00Z" }
]
}
}
```

You don't need any markup — Postproxy auto-converts `@handles`, `#tags`, and URLs into AT Protocol facets, and generates a link card preview from the URL's Open Graph meta (when no media is attached). 300-grapheme limit.
#### Telegram Examples
**Telegram channel post (HTML formatting):**
```json
{
"content": "<b>New release</b> — read more on our blog https://example.com/post",

"telegram": {
"chat_id": "-1001234567890",
"parse_mode": "HTML",
"disable_link_preview": true,
"disable_notification": false

Use `profiles_placements` against your Telegram profile to list channel `chat_id`s the bot can post to. The bot must be added to the channel as administrator with permission to post.

## Troubleshooting
### Server Won't Start
- **Check API Key**: Ensure `POSTPROXY_API_KEY` is set when registering with `claude mcp add`
- **Check Node Version**: Requires Node.js >= 18.0.0
- **Check Installation**: Verify `postproxy-mcp` is installed and in PATH
- **Check Registration**: Ensure the server is registered via `claude mcp add` and configuration is saved in `~/.claude/plugins/`
### Authentication Errors
- **AUTH_MISSING**: API key is not configured. Make sure you included `--env POSTPROXY_API_KEY=...` when running `claude mcp add`
- **AUTH_INVALID**: API key is invalid. Verify your API key is correct.
### Validation Errors
- **TARGET_NOT_FOUND**: One or more profile IDs don't exist. Use `profiles_list` to see available profiles.
- **VALIDATION_ERROR**: Post content or parameters are invalid. The API now returns detailed error messages:
- **400 errors**: `{"status":400,"error":"Bad Request","message":"..."}`
- **422 errors**: `{"errors": ["Error 1", "Error 2"]}` - Array of validation error messages
- Check the error message for specific validation issues
### API Errors
- **API_ERROR**: PostProxy API returned an error. Check the error message for details.
- **Timeout**: Request took longer than 30 seconds. Check your network connection and API status.
### Platform Errors
When checking post status with `post_status`, platform-specific errors are now available in the `error` field of each platform object:
- `error: null` - Post published successfully
- `error: "Error message"` - Detailed error message from the platform API
- Common errors include authentication issues, rate limits, content violations, etc.
### Draft Post Issues
If you create a draft post (`draft: true`) but receive `draft: false` in the response:
- The response will include a `warning` field explaining that the API may have ignored the draft parameter
- This can happen if:
- The API does not support drafts with media attachments
- The API has specific limitations for draft posts under certain conditions
- Check the `warning` field in the response for details
- Enable debug mode (`POSTPROXY_MCP_DEBUG=1`) to see detailed logging about draft parameter handling
### Debug Mode
Enable debug logging by setting `POSTPROXY_MCP_DEBUG=1` when registering the server:
```bash
claude mcp add --transport stdio postproxy-mcp --env POSTPROXY_API_KEY=your-api-key --env POSTPROXY_BASE_URL=https://api.postproxy.dev/api --env POSTPROXY_MCP_DEBUG=1 -- postproxy-mcp
```
