What is MCP?

The Model Context Protocol (MCP) is an open protocol designed to standardize how applications provide contextual information to large language models (LLMs). Much like how USB-C serves as a universal interface for connecting hardware devices, MCP acts as a universal connector between AI models and various data sources or tools. This standardization simplifies integration and enhances the adaptability and functionality of AI-powered applications.

Why MCP?

MCP helps you build agents and complex workflows on top of LLMs. LLMs frequently need to integrate with data and tools, and MCP provides:

• A growing list of pre-built integrations that your LLM can directly plug into
• The flexibility to switch between LLM providers and vendors
• Best practices for securing your data within your infrastructure

General architecture

At its core, MCP follows a client-server architecture where a host application can connect to multiple servers:

• MCP Hosts: Programs like Claude Desktop, IDEs, or AI tools that want to access data through MCP
• MCP Clients: Protocol clients that maintain 1:1 connections with servers
• MCP Servers: Lightweight programs that each expose specific capabilities through the standardized Model Context Protocol
• Local Data Sources: Your computer’s files, databases, and services that MCP servers can securely access
• Remote Services: External systems available over the internet (e.g., through APIs) that MCP servers can connect to

Get started

1. Clone the repository

git clone https://github.com/Eacus/misp-mcp.git

2. Install Claude Desktop

   1. Follow the guide https://modelcontextprotocol.io/quickstart/user
   2. Add the following MCP configuration

   {
       "mcpServers": {
           "MISP-mcp":{
                       "command": "uv",
               "args": [
                   "--directory",
                   "<path_to_repo>/server/",
                   "run",
                   "server.py"
               ]
           }
       }
   }
   

3. Restart Claude desktop

Basic Usage

Search Event by ID

Prompting with misp-mcp

Can you give to me the MISP event with id 119?

GUI

PyMISP

misp_url = 'https://127.0.0.1:8443'
misp_key = '<misp_key>'
# Should PyMISP verify the MISP certificate
misp_verifycert = False
r = misp.search(eventid=[119], metadata=True, pythonify=True)

Create an event

Prompting with misp-mcp

Create a new MISP event with the following parameters:

• Info: This is my new MISP event
• Distribution: 0 (Your organization only)
• Threat Level ID: 2 (Medium)
• Analysis Level: 1 (Ongoing)

GUI

PyMISP

from pymisp import MISPEvent

event = MISPEvent()

event.info = 'This is my new MISP event'  # Required
event.distribution = 0  # Optional, defaults to MISP.default_event_distribution in MISP config
event.threat_level_id = 2  # Optional, defaults to MISP.default_event_threat_level in MISP config
event.analysis = 1  # Optional, defaults to 0 (initial analysis)

print(event.to_json())

Administrative task

Create an user

Prompting with misp-mcp

Add a new user to the MISP instance using the following required fields:

• email@email.com: the email address associated with the account
• test_id: the ID of the organization the user belongs to
• role_id: the ID of the role assigned to the user

GUI

PyMisp

from pymisp import ExpandedPyMISP, MISPUser
from keys import misp_url, misp_key, misp_verifycert
import argparse


    misp = ExpandedPyMISP(misp_url, misp_key, misp_verifycert, 'json')

    user = MISPUser()
    user.email = <email>
    user.org_id = <org_id>
    user.role_id = <role_id>

    misp.add_user(user, pythonify=True)
