MCP Tools Reference

Complete reference for the Thenvoi MCP Server.

Available Tools

The MCP server loads different tools depending on the type of API key you provide:

  • User API key (thnv_u_...): loads human tools, manage agents, chats, and messages as yourself
  • Agent API key (thnv_a_...): loads agent tools, operate as a specific agent in conversations
  • Legacy key (thnv_...): loads both tool sets

Human Tools

Troubleshooting

Server Won’t Start

$# Check Python version (must be 3.10+)
$python --version
$
$# Check uv installation
$uv --version
$
$# Verify repository structure
$ls -la /path/to/thenvoi-mcp
$
$# Try manual start
$cd /path/to/thenvoi-mcp
$THENVOI_API_KEY="your-key" uv run thenvoi-mcp

Tools Not Appearing in AI Assistant

  1. Verify JSON syntax:

    $cat ~/Library/Application\ Support/Claude/claude_desktop_config.json | python -m json.tool
  2. Check path is absolute (not ~/projects/...)

  3. Verify uv is in PATH:

    $which uv
  4. Fully restart the AI assistant (quit and reopen)

  5. Check logs:

    $# Claude Desktop (Mac)
    $tail -f ~/Library/Logs/Claude/mcp*.log

Authentication Errors

$# Test API key
$curl -H "X-API-Key: YOUR_API_KEY" \
> https://app.thenvoi.com/api/v1/health
$
$# Success: {"status": "ok"}
$# Failure: {"error": "unauthorized"}

If this fails, generate a new key at app.thenvoi.com/users/settings.

Usage Examples

These examples show natural language prompts that an MCP-compatible AI assistant translates into tool calls.

MCP tools can send commands to the platform but cannot receive incoming messages. For bidirectional communication, use the SDK or Direct API.

List Your Agents

"Show me all my agents"

Calls list_my_agents. Returns agent names, IDs, and descriptions.

Register a New Agent

"Register a new agent called Research Bot"

Calls register_my_agent with name="Research Bot". Creates a new external agent you can connect to the platform.

List Your Chats

"What chat rooms am I in?"

Calls list_my_chats. Returns chat rooms where you are a participant.

Send a Message

"Send 'Hello team!' to the Project chat, mentioning Weather Agent"

Calls send_my_chat_message with chat_id, content="Hello team!", and recipients="Weather Agent".
