Socials, by chat.
Connect Blendin to the chat assistant you already use. Ask it to line up your week, check it with a dry run, answer comments and read your numbers. You stay in control through scopes, dry runs and keys you can revoke.
OAuth works on every plan, Free included.
The short answer
Connect in three steps.
- 1
Add the URL
In your assistant's connector settings, add https://app.blendin.ai/api/mcp as a remote MCP server.
- 2
Sign in, pick permissions
You sign in as the workspace owner and tick which permissions to grant. Nothing else is shared.
- 3
Ask in plain words
Try: plan next week, dry run first. The assistant calls the tools and reports back.
What an assistant can do.
Every tool follows your permissions. Reads are marked read only, and anything destructive is marked as such.
Line up your week
List your accounts and scheduled posts, then use the plan_my_week prompt to propose a day by day plan and ask for your approval.
Check, then schedule
Run publish_post as a dry run first. It checks every account and sends nothing. Then schedule it for the time you set.
Answer comments
Read comments by permission and send a public reply with exactly the words you give it, up to 2,200 characters.
Read the numbers
Pull post analytics, account insights and your top posts. A number that is not there yet comes back empty, never as zero.
Keep the brand straight
Read your brand kits and update their style fields: colours, fonts, tone and visual style.
Make things
On the full endpoint, an assistant can also start a generation or a code rendered video. It uses your plan allowance and gives it back if the job fails.
You choose the permissions.
| Default: publish, accounts:read | Check and send posts, schedule, reschedule and cancel, upload media, list your connected accounts. Always on a default key. |
|---|---|
| library:read and library:write | List and read posts, see the calendar, and edit a caption or a first comment. |
| comments:read and comments:write | Read and reply to comments on Instagram, and moderate TikTok Business comments. |
| inbox:read and inbox:write | Read DM conversations and reply as your own text, inside the 24 hour window. Needs the DM Inbox, which is rolling out. |
| analytics:read | Post analytics, account insights and top posts. |
| brand_kits:read and brand_kits:write | Read your brand kits and edit their style fields. |
| lead_flows, link_in_bio, webhooks | Each has its own read and write permission. Lead Flows tools need Lead Flows, which is rolling out. |
| generate | Start a generation. Full endpoint only, and it uses your plan allowance. |
How the connection works.
| Transport | Streamable HTTP, protocol 2025-11-25. |
|---|---|
| Sign in | OAuth 2.1 with discovery, dynamic registration and PKCE with S256. |
| Tokens | An access token lasts one hour. The refresh token rotates on every use. |
| Who can sign in | The workspace owner, on any plan. A teammate is refused. |
| Personal keys | A key that starts with bln_live_ also works. Keys you create yourself, per plan, are in the table below. |
| Rate limit | 120 requests a minute per account, shared by every key and connection. |
| /api/mcp | The full server: every tool your permissions allow, generation included. |
|---|---|
| /api/mcp/directory | The same tools without the generative ones, built for assistant directories. |
| Resources | blendin://calendar for the next 30 days and blendin://brand-kits/{id}. |
| Prompt | plan_my_week: reads your calendar, top posts and drafts, proposes a plan, asks for approval, then schedules with a dry run first. |
| Revoking | Every connected assistant is listed under Developers in the app and can be revoked there. |
| Free | Creator | Pro | Business | |
|---|---|---|---|---|
| API keys you create yourself | 0 | 2 | 5 | 10 |
| MCP over OAuth | Yes | Yes | Yes | Yes |
What the MCP server does not do
Ask us anything.
What is the Blendin MCP server?
A remote MCP server that lets a chat assistant or coding agent use your Blendin account. It speaks Streamable HTTP, protocol 2025-11-25. Through it an assistant can list your accounts, create and schedule posts with dry runs, read comments and analytics, and, where you allow it, read the inbox.
Which assistants can connect?
Any assistant or coding agent that supports remote MCP over Streamable HTTP and OAuth 2.1 with PKCE. Add https://app.blendin.ai/api/mcp, sign in as the workspace owner and tick the permissions. The assistant then discovers the tools those permissions allow.
Do I need a paid plan to use MCP?
No. MCP over OAuth works on every plan, Free included. API keys you create yourself are separate: Free has none, Creator 2, Pro 5 and Business 10, and a personal key also works with MCP.
Can my assistant publish without asking me?
Only if you give it the publish permission. Blendin does not add its own approval click to a post an assistant sends: a publish call goes out right away, and one with a time stored is sent at that time. You stay in control through the scopes you grant, dry runs (which check everything and send nothing), scheduling and keys you can revoke. The plan_my_week prompt asks for your approval before it schedules anything.
What can my assistant read?
Only what you tick on the consent screen. A default key gets publishing and the account list. Everything else is opt in: library, comments, inbox, analytics, brand kits, Lead Flows, Link in bio and webhooks, each as its own read or write permission.
What is the directory endpoint?
A second URL, /api/mcp/directory, that serves every tool except the generative ones. The full endpoint, /api/mcp, also includes tools that start a generation, which use your plan allowance.
How do I disconnect an assistant?
Open Developers in the app. Each connected assistant is listed on the MCP tab and can be revoked there. Its access token lasts one hour and the refresh token rotates on every use.
Can my assistant read my DMs?
Only if you grant the inbox permissions and the DM Inbox is on for your account. The DM Inbox is rolling out. Replies go only inside Instagram's 24 hour window and only as the exact text you pass.
Is it safe to connect?
You choose the permissions, the person signing in must be the workspace owner, reads are marked read only, destructive tools are marked destructive, and every account is limited to 120 requests a minute. You can revoke an assistant at any time.
Hand it your chores.
Free plan, no card. Connect an account, then add the Blendin URL to your assistant.
