Expose raw Martian manifests to your LangChain agents

This MCP Server exposes the `get_mars_manifest` tool so your agent can verify mission status, active sol ranges, and camera configurations before requesting high-resolution imagery. Your agent reads the raw JSON payload to determine which dates actually contain valid data, preventing empty API responses. You pass this manifest directly into subsequent chain steps to build smart validation layers. This approach prevents your chains from wasting API rate limits on invalid sols or inactive cameras.

Chain date-based queries with LangChain visual tools

The `get_mars_photos_by_date` tool lets your agent fetch raw image metadata using standard Earth calendar dates instead of converting to Martian sols. By injecting this MCP tool into a LangChain multi-step chain, your agent automatically correlates historical Earth news events with actual photos taken on Mars that day. The output feeds directly into your downstream image-processing nodes or multi-modal models. You get a direct, observable pipeline that handles the entire translation from user query to raw visual data.

Filter Curiosity, Spirit, and Opportunity photos by camera

The `get_mars_photos` and `get_mars_latest` tools retrieve raw photo links filtered by specific onboard hardware like NAVCAM, MAST, or CHEMCAM. LangChain agents use these tools to execute targeted visual analysis based on the specific scientific instruments required for the user's prompt. Because this MCP Server handles the raw NASA API calls, your agent simply decides which camera fits the context and issues the query. The resulting image URLs feed straight into your visual LLMs for real-time analysis.

Setup guide

Set up NASA Mars — Rover Photos from the Red Planet MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes NASA Mars — Rover Photos from the Red Planet tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "nasa-mars-rover-photos-from-the-red-planet-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent NASA Mars — Rover Photos from the Red Planet transactions"
    })
    print(result["messages"][-1].content)

Common questions about NASA Mars — Rover Photos from the Red Planet MCP in LangChain

You should use LangSmith to trace your tool calls and monitor how often your agent invokes the MCP server. To protect your limits, have your agent call `get_mars_manifest` first to verify valid sols before requesting photos.

Yes, your agent uses the tool descriptions to choose between cameras like FHAZ or MAST. It evaluates the user's intent, selects the correct camera parameter, and calls `get_mars_photos` to retrieve the relevant images.

Install `langchain-mcp-adapters` and initialize the `MultiServerMCPClient` with your Vinkius endpoint. You then fetch the tools and pass them directly to your agent's initialization step.

Yes, you can query the complete historical archives for both Spirit and Opportunity. Use `get_mars_manifest` to find their active sol ranges, then pull photos from those specific periods.

This integration only transmits public rover metadata, camera names, and sol numbers to the NASA API. No private code, prompt histories, or personal files are sent to external servers.
