Perplexity

Parse past copies into LangChain pipelines

The `search_clipboard_history` tool reads your JSON or TXT exports from Maccy or CopyQ so your agent can find exact text matches. You dump your local clipboard history to a file, and LangChain treats it like any other data source. We built this because scrolling through thousands of old copied items manually is a waste of time. Chain this search step with other operations. A ReAct agent can query the history for a specific API key you copied Tuesday, extract it, and pass it directly into an HTTP request tool. LangSmith will trace the exact token usage and latency for the search operation.

Connect MCP Server tools to vector stores

Calling `search_clipboard_history` pulls raw strings out of your Ditto export and feeds them into your LangChain workflow. Your agent decides when to trigger the search based on the user's prompt. It parses the file structure automatically, regardless of whether you exported plain text or structured JSON. Build a pipeline that runs daily. The chain grabs the latest clipboard dump, filters out short strings, and pushes the useful code snippets into a Pinecone database. You get a searchable archive of everything you thought was important enough to hit Cmd+C on.

Build multi-step retrieval agents

Exposing `search_clipboard_history` gives your ReAct agent the ability to dig through your short-term memory exports. Ask the agent for that weird regex pattern you copied from Stack Overflow last week. It hits the MCP tool, scans the file, and returns the exact match. The output becomes the input for the next step. If the agent finds a URL in the clipboard data, it can immediately call a web scraper tool to summarize the page. Everything runs through the Vinkius HTTP transport, keeping the connection stable while your agent iterates.

Setup guide

Set up Clipboard History Searcher 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 Clipboard History Searcher 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({
    "clipboard-history-searcher-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 Clipboard History Searcher transactions"
    })
    print(result["messages"][-1].content)

Common questions about Clipboard History Searcher MCP in LangChain

Install `langchain-mcp-adapters`. Pass your Vinkius HTTP endpoint into `MultiServerMCPClient` and call `get_tools()`. Then hand those tools to your ReAct agent.

Yes. The agent reads the tool description and triggers a search only when it needs to find a past copied item. You don't have to hardcode the execution order.

It integrates natively. You can add the MCP Server tool as a node in your state graph. The output updates your graph state for the next step.

You get full observability through LangSmith. You can see exactly what query the agent ran against your Ditto export and how long the parse took.

We run your server in an ephemeral V8 Isolate Sandbox. Your exported passwords, private keys, and sensitive texts are processed in memory and destroyed immediately after the LangChain tool call finishes.
