Common questions
Is Postproxy safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: X-PostProxy-API-Key
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.10.0) reached the registry 5 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

Postproxy MCP Server
MCP (Model Context Protocol) server for integrating Postproxy API with Claude Code. This server provides tools for publishing posts, checking statuses, and managing social media profiles through Claude Code.
Installation
Global Installation
npm install -g postproxy-mcp
Local Installation
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:
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:
- Restart your Claude Code session
- Test the connection by asking Claude: "Check my Postproxy authentication status"
- 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:
postproxy-mcp setup
or
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:
{
"authenticated": true, "base_url": "https://api.postproxy.dev/api", "profile_groups_count": 2 }
Account Overview
summary_get
Answer "what's the status?" in one call — an activity snapshot for a time window instead of separate history_list / comments_list / dm_chats_list round trips.
Parameters:
window(string, optional):24h(default),7d, or30dfrom(string, optional): ISO 8601 timestamp or bare date starting an explicit range. Overrideswindow, and the*_previouscounts come backnullto(string, optional): End of the explicit range. Defaults to now when onlyfromis givenprofile_group_id(string, optional): Report on a single group. Omit to cover every group the key can reach
Returns:
{
"window": { "label": "24h", "from": "2026-08-17T09:00:00Z", "to": "2026-08-18T09:00:00Z", "previous_from": "2026-08-16T09:00:00Z", "backlog_from": "2026-07-19T09:00:00Z" }, "posts": { "published": 4, "published_previous": 3, "failed": 1, "scheduled_ahead": 6, "next_scheduled_at": "2026-08-18T14:00:00Z", "by_platform": { "instagram": { "published": 4, "failed": 0 } } }, "engagement": { "total": { "impressions": 48210, "likes": 1204 }, "by_platform": { "instagram": { "impressions": 31002, "likes": 900 } }, "posts_with_insights": 14 }, "comments": { "received": 96, "received_previous": 71, "awaiting_reply": 12, "by_platform": { "instagram": 61 } }, "reviews": { "received": 7, "received_previous": 4, "awaiting_reply": 3 }, "dms": { "inbound": 41, "outbound": 33, "chats_awaiting_reply": 5, "reply_window_closing": 2 }, "api": { "calls": 812, "calls_previous": 640 } }
Notes:
- Post counts are posts, so a post sent to three networks counts once and a thread counts once.
by_platformcounts per-network deliveries, so a 3-item X thread is 3 undertwitter. - `engagement` is lifetime-to-date for posts published in the window, not engagement earned during it — it sums each post's newest stats snapshot. A post published minutes ago may have no snapshot yet and won't be in
posts_with_insights. Keys are the normalized metrics listed in Stats Fields by Platform. - The `awaiting_reply` counts describe current state, not the window — they don't change when you change
window. They look back 30 days, returned aswindow.backlog_from. A comment counts as replied only when the reply came from you (via Postproxy or the profile itself);chats_awaiting_replyis derived from message timestamps, since Postproxy has no read/unread state. reply_window_closingcounts chats with under 6 hours of their 24h messaging window left. Networks without a window (Telegram, Bluesky) are excluded.engagementisnullwhen insights are off for the account;dmsisnullwhen DMs are off.- Scoped like every other tool: a group-scoped key reports only its group.
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:
{
"profile_groups": [ { "id": "grp123abc", "name": "Main Brand", "profiles_count": 4 } ] }
profile_groups_initialize_connection
Generate a connect URL for a new profile in a profile group. The user opens the URL to finish the OAuth flow.
Parameters:
profile_group_id(string, required): Profile group IDplatform(string, required): Platform to connect (e.g.instagram,linkedin,whatsapp)onboarding(string, optional): Instagram and WhatsApp only. Instagram:instagram(default) uses Instagram Login;facebookuses Facebook Login, for an Instagram professional account linked to a Facebook Page you manage. The profile isplatform: "instagram"either way, and reconnecting with the other method updates the existing profile in place. WhatsApp:apiorbusiness_app(see WhatsApp Business Management).identifier+app_password(Bluesky) /bot_token(Telegram): credentials, local server only
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 (useprofile_groups_listto find group IDs)
Returns:
{
"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. For Google Business profiles, placements are locations, returned as full resource paths (accounts/X/locations/Y) to pass as location_id. For WhatsApp profiles, placements are the phone numbers on the Business Account — the placement id is the phone_number_id every whatsapp_* tool and dm_chat_create take. Available for facebook, linkedin, pinterest, telegram, google_business, and whatsapp profiles.
Parameters:
profile_id(string, required): Profile hashid
Returns (LinkedIn example):
{
"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_idis required on every post - Google Business: it fails —
location_idis required on every post and on everygoogle_business_*tool
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 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 hashidplacement_id(string, conditional): Required forfacebook,linkedin,telegram, andgoogle_businessprofiles. Get it fromprofiles_placements. Omit forinstagram,threads,youtube,twitter,tiktok,pinterest, andbluesky.from(string, optional): ISO 8601 timestamp — only include snapshots recorded at or after this timeto(string, optional): ISO 8601 timestamp — only include snapshots recorded at or before this time

For non-placement networks (e.g. Bluesky), omit placement_id:
{
"data": { "profile_id": "prof_bsky_001", "platform": "bluesky", "placement_id": null, "records": [ { "stats": { "followersCount": 8800, "postsCount": 40 }, "recorded_at": "2026-05-09T08:00:00Z" } ] } }
