How to Use the TextP2P MCP in Pydantic AI

Q: How do I safely add new contacts with TextP2P and Pydantic AI?

You use the addtextp2pcontact tool. Because of runtime validation, it won't accept a phone number that isn't in the expected format, keeping your data clean.

Q: What different types of messaging can TextP2P and Pydantic AI handle?

The system supports basic SMS via sendtextp2psms, richer content with MMS using sendtextp2pmms, and personal touches through RVM calls (sendtextp2prvm).

Q: Is checking the balance reliable with TextP2P and Pydantic AI?

Yes. Calling gettextp2pbalance confirms your current account credit using a strictly defined numerical model, eliminating guesswork about spending limits.

Q: What is the best way to check which lists are available with TextP2P and Pydantic AI?

Call listtextp2plists. The toolset validates that every list name returned matches the expected string type, so you don't send messages to a non-existent group.

Perplexity

Verify and create contact records.

The `add_textp2p_contact` tool requires structured input, making sure new contacts are stored correctly. It validates that the phone number format is right before creating a record. This level of type safety means your agent never gets confused by bad data entering the system.

Execute multi-stage messaging flows.

The `send_textp2p_sms` tool sends standard messages, but it guarantees that the target list ID is valid. If the input fails validation, the agent stops and tells you exactly why. You can chain this with `send_textp2p_mms` or `send_textp2p_rvm`, knowing every step passed its type check.

Check list status before sending.

Before sending, use `list_textp2p_lists` to verify the group name you want. The toolset enforces that this list actually exists and is readable by the agent. Similarly, calling `get_textp2p_balance` confirms your credit usage against a defined numerical model.

Setup guide

Set up TextP2P MCP in Pydantic AI

Prerequisites

Python 3.10+ installed
pydantic-ai-slim[fastmcp] package
Active Vinkius subscription with a valid endpoint token

1

Install Pydantic AI with FastMCP
Run pip install "pydantic-ai-slim[fastmcp]". The FastMCP toolset replaces the deprecated MCPServerHTTP class with full protocol support.
2

Configure the FastMCPToolset
Pass a JSON-style config dict to FastMCPToolset with your Vinkius URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports Streamable HTTP, SSE, and Stdio transports.
3

Create and run your agent
Pass the toolset to Agent(toolsets=[toolset]) and call agent.run(). Swap openai:gpt-4o for any supported model — Anthropic, Google, Mistral, or Groq.

agent.py

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
    "mcpServers": {
