| `ZERNIO_MCP_POSTS_CREATE` | Posts create | Create a social media post. Can be saved as DRAFT, SCHEDULED, or PUBLISHED immediately. ⚠️ IMPORTANT - Choose the correct mode based on user intent: **DRAFT MODE (is_draft=True)** Use when user says: "draft", "borrador", "save for later", "don't publish", "save it", "guardar" → Post is saved but NOT published and NOT scheduled. User can edit it later. **IMMEDIATE MODE (publish_now=True)** Use when user says: "publish now", "post now", "publica ya", "immediately", "right now", "ahora" → Post goes live IMMEDIATELY. **SCHEDULED MODE (default)** Use when user says: "schedule", "programar", "in X minutes/hours", "at 3pm", "tomorrow" → Post is scheduled for future publication. Use schedule_minutes to set the delay. ⚠️ MULTI-ACCOUNT USERS (agencies, multi-client setups): If the user has more than one account on the target platform, you MUST pass `account_id`. Call `accounts_list` (or `profiles_list` then `accounts_list`) first to discover the right ID. If you omit account_id when multiple accounts exist, the tool returns an error listing the candidates - use it to retry. Examples: - "Create a draft tweet" → is_draft=True - "Post this to Twitter now" → publish_now=True - "Schedule a LinkedIn post for 2 hours from now" → schedule_minutes=120 - "Post this to Acme's Twitter" → call accounts_list, find Acme's twitter ID, pass account_id |
| `ZERNIO_MCP_POSTS_CROSS_POST` | Posts cross post | Post the same content to multiple platforms at once. ⚠️ IMPORTANT - Choose the correct mode based on user intent: **DRAFT MODE (is_draft=True)** Use when user says: "draft", "borrador", "save for later", "don't publish" → Posts are saved but NOT published. User can edit them later. **IMMEDIATE MODE (publish_now=True)** Use when user says: "publish now", "post now", "immediately" → Posts go live IMMEDIATELY on all platforms. **SCHEDULED MODE (default)** Use when user says: "schedule", "programar", "in X hours" → Posts are scheduled for 1 hour from now. ⚠️ MULTI-ACCOUNT USERS: - To pick a specific account per platform, pass `account_ids` parallel to `platforms` (same order, comma-separated). Use empty string for a position to fall back to profile/auto-resolution. - To target multiple accounts of the SAME platform in one call, repeat the platform: platforms='twitter,twitter', account_ids='acc_a,acc_b'. - If you omit account_ids and the user has multiple accounts for any of the requested platforms, the tool errors with the candidate list - use it to retry. |
| `ZERNIO_MCP_POSTS_DELETE` | Posts delete | Delete a post by ID. Published posts cannot be deleted. |
| `ZERNIO_MCP_POSTS_EDIT_POST` | Posts edit post | Edit published post |
| `ZERNIO_MCP_POSTS_GET` | Posts get | Get full details of a specific post including content, status, and scheduling info. |

| `ZERNIO_MCP_POSTS_PUBLISH_NOW` | Posts publish now | Publish a post immediately to a platform. The post goes live right away. Use this when user explicitly wants to publish NOW, not schedule for later. This is a convenience wrapper around posts_create with publish_now=True. ⚠️ MULTI-ACCOUNT USERS: pass `account_id` when the user has more than one account on this platform. Call `accounts_list` first to find the right ID. |
| `ZERNIO_MCP_POSTS_RETRY` | Posts retry | Retry publishing a failed post. Only works on posts with 'failed' status. |

| `ZERNIO_MCP_USAGE_GET_USAGE` | Usage get usage | Usage snapshot (default) or billed-spend metering (with params) Args: reconcile: Snapshot mode only. For Stripe subscription users, `true` forces a subscription reconciliation pass even when cached plan data looks complete. range: Window to report. `cycle` / `prev-cycle` resolve to the customer's real billing-period bounds (falling back to a trailing 30 days when no invoice exists yet); `7d`…`12mo` are trailing windows; `custom` uses `from` / `to`. from_: Inclusive start (UTC date). Required when `range=custom`. to: Inclusive end (UTC date). Required when `range=custom`. Max span 366 days. granularity: Bucketing of the `days` series: `day` (one row per UTC day), `month` (one row per calendar month, dated to the 1st), or `total` (no series, read `totals`). Does not affect `totals`. group_by: Metering mode. Adds `attribution`: the window's spend split per profile or per account (keys are ids; resolve names via `GET /v1/profiles` / `GET /v1/accounts`). profile_id: Metering mode (pair with `range`). Project the payload onto this profile's attributed share. Mutually exclusive with `accountId`, and `groupBy` (if given) must be `profile`; 404 when the profile is not in your team (or outside a scoped key's profiles). account_id: Metering mode (pair with `range`). Project the payload onto this account's attributed share. Mutually exclusive with `profileId`, and `groupBy` (if given) must be `account`; 404 when the account is not visible to the caller. |
| `ZERNIO_MCP_VALIDATE_MEDIA` | Validate media | Validate media URL |
| `ZERNIO_MCP_VALIDATE_POST` | Validate post | Validate post content |
| `ZERNIO_MCP_VALIDATE_POST_LENGTH` | Validate post length | Validate character count |

## Installation and MCP Setup

### Path 1: SDK Installation

#### Path 1, Step 1: Install Composio

Install the Composio SDK, the OpenAI provider, and the OpenAI SDK
```python
pip install composio composio_openai openai
```

```typescript
npm install @composio/core @composio/openai openai
```

#### Path 1, Step 2: Create a Composio session

Initialize Composio with the OpenAI Responses provider and create a session scoped to Zernio MCP
```python
import json
from openai import OpenAI
from composio import Composio
from composio_openai import OpenAIResponsesProvider

composio = Composio(provider=OpenAIResponsesProvider())
client = OpenAI()

session = composio.create(user_id="your-user-id", toolkits=["zernio_mcp"])
tools = session.tools()
```

```typescript
import OpenAI from "openai";
import { Composio } from "@composio/core";
import { OpenAIResponsesProvider } from "@composio/openai";

const composio = new Composio({ provider: new OpenAIResponsesProvider() });
const client = new OpenAI();

const session = await composio.create("your-user-id", { toolkits: ["zernio_mcp"] });
const tools = await session.tools();
```

#### Path 1, Step 3: Run Zernio MCP tools with your agent

Send a request, execute the Zernio MCP tool calls through the session, and print the final answer
```python
response = client.responses.create(
    model="gpt-5.6-sol",
    tools=tools,
    input=[{"role": "user", "content": "Schedule a LinkedIn post for tomorrow at 9 AM announcing our product launch"}],
)

while True:
    tool_calls = [o for o in response.output if o.type == "function_call"]
    if not tool_calls:
        break
    results = composio.provider.handle_tool_calls(response=response, session=session)
    response = client.responses.create(
        model="gpt-5.6-sol",
        tools=tools,
        previous_response_id=response.id,
        input=[
            {"type": "function_call_output", "call_id": call.call_id, "output": json.dumps(results[i])}
            for i, call in enumerate(tool_calls)
        ],
    )

print(response.output_text)
```

```typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "Schedule a LinkedIn post for tomorrow at 9 AM announcing our product launch" }],
});

while (response.output.some((o) => o.type === "function_call")) {
  const outputs = await composio.provider.handleToolCalls(session, response.output);
  response = await client.responses.create({
    model: "gpt-5.6-sol",
    tools,
    previous_response_id: response.id,
    input: outputs,
  });
}

console.log(response.output_text);
```

### Path 2: MCP Server Setup

#### Path 2, Step 1: Install Composio

Install the Composio SDK and your agent framework
```python
pip install composio claude-agent-sdk
```

```typescript
npm install @composio/core ai @ai-sdk/mcp @ai-sdk/openai
```

#### Path 2, Step 2: Create a session with MCP enabled

Create a session scoped to Zernio MCP and read its MCP URL and headers
```python
from composio import Composio

composio = Composio()
session = composio.create(user_id="your-user-id", toolkits=["zernio_mcp"], mcp=True)
```

```typescript
import { Composio } from "@composio/core";

const composio = new Composio();
const { mcp } = await composio.create("your-user-id", {
  toolkits: ["zernio_mcp"],
  mcp: true,
});
```

#### Path 2, Step 3: Connect your agent to the MCP server

Pass the session's MCP URL and headers to your agent and run a Zernio MCP request
```python
import asyncio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions, AssistantMessage, TextBlock

options = ClaudeAgentOptions(
    mcp_servers={
        "composio": {
            "type": "http",
            "url": session.mcp.url,
            "headers": session.mcp.headers,
        }
    },
    system_prompt="You are a helpful assistant with access to Zernio MCP tools.",
    tools=[],
    allowed_tools=["mcp__composio__*"],
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query("Schedule a LinkedIn post for tomorrow at 9 AM announcing our product launch")
        async for message in client.receive_response():
            if isinstance(message, AssistantMessage):
                for block in message.content:
                    if isinstance(block, TextBlock):
                        print(block.text)

asyncio.run(main())
```

```typescript
import { createMCPClient } from "@ai-sdk/mcp";
import { openai } from "@ai-sdk/openai";
import { generateText, stepCountIs } from "ai";

const client = await createMCPClient({
  transport: { type: "http", url: mcp.url, headers: mcp.headers },
});

const { text } = await generateText({
  model: openai("gpt-5.6-sol"),
  tools: await client.tools(),
  prompt: "Schedule a LinkedIn post for tomorrow at 9 AM announcing our product launch",
  stopWhen: stepCountIs(10),
});

console.log(text);
await client.close();
```
