How to Use the NavAPI MCP in LlamaIndex

Q: Does NavAPI support filtered tool access in LlamaIndex?

Yes. You can use the allowedtools filter to restrict which functions your agent can access during its indexing process.

Ground your LlamaIndex knowledge base in live maritime data from the NavAPI MCP Server.

Index NavAPI data in LlamaIndex

Transform `get_nautical_ports` output into structured knowledge entries. Your RAG application queries this index to find specific port details without manual lookup. LlamaIndex handles the heavy lifting of turning API responses into searchable vectors. You get answers grounded in live data, not static training sets.

Contextual maritime search for LlamaIndex

Combine `search_maritime_routes` results with your existing documents. Your AI client builds a unified index where shipping routes and internal logs coexist. This gives your agent a complete picture of your operations. It connects the dots between what you planned and what the data says is currently happening.

Verify system health in LlamaIndex

Execute `check_api_status` as a pre-query step in your pipeline. Your agents confirm the NavAPI is reachable before attempting to index or search maritime records. Handle failures gracefully. If the status check returns an error, your agent can pause or alert you before your index gets stale data.

Setup guide

Set up NavAPI MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all NavAPI MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to NavAPI tools.",
)
response = await agent.run("List recent NavAPI data")
