You can do this in two different ways: - Via [Composio Connect](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=claude-code&utm_content=composio_connect&next=%2F~%2Forg%2Fconnect%2Fclients%2Fclaude-code) - Direct and easiest approach - Via [Composio SDK](https://docs.composio.dev/docs?utm_source=toolkits&utm_medium=framework_template&utm_campaign=claude-code&utm_content=composio_sdk) - Programmatic approach with more control ## Also integrate Securitytrails with - [OpenAI Agents SDK](https://composio.dev/toolkits/securitytrails/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/securitytrails/framework/claude-agents-sdk) - [Claude Cowork](https://composio.dev/toolkits/securitytrails/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/securitytrails/framework/codex) - [OpenClaw](https://composio.dev/toolkits/securitytrails/framework/openclaw) - [Hermes](https://composio.dev/toolkits/securitytrails/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/securitytrails/framework/cli) - [Google ADK](https://composio.dev/toolkits/securitytrails/framework/google-adk) - [LangChain](https://composio.dev/toolkits/securitytrails/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/securitytrails/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/securitytrails/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/securitytrails/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/securitytrails/framework/crew-ai) ## TL;DR - Only one MCP URL to connect multiple apps with Claude Code with zero auth hassles. - Programmatic tool calling allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Handling Large tool responses out of LLM context to minimize context rot. - Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need. ## Connect Securitytrails to Claude Code ### Connecting Securitytrails to Claude Code using Composio 1. Add the Composio MCP to Claude ```bash claude mcp add --scope user --transport http composio https://connect.composio.dev/mcp ``` ## What is Claude Code? Claude Code is Anthropic's command line developer tool that lets you use Claude directly inside your terminal. Instead of switching between your editor, browser, and chat, you can stay in your project folder and ask Claude to help you build, debug, refactor, and understand code right where you're working. Key features include: - Terminal-Native Experience: Work with Claude directly in your command line without switching contexts - MCP Support: Built-in support for Model Context Protocol servers to extend Claude's capabilities - Project Context: Claude understands your project structure and can read, write, and modify files - Interactive Development: Ask questions, debug code, and get help in real-time while coding - Multi-Platform: Works on macOS, Linux, WSL, and Windows ## What is the Securitytrails MCP server, and what's possible with it? The Securitytrails MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Securitytrails account. It provides structured and secure access to domain and IP intelligence data, so your agent can perform actions like retrieving domain details, analyzing IP associations, running custom SQL queries, and managing static asset rules on your behalf. - Domain and DNS intelligence: Instantly fetch detailed information about any domain, including current DNS record statistics and associated data for robust cybersecurity analysis. - SSL certificate retrieval: Access current and historical SSL certificate details for any hostname, helping you track certificate changes or potential vulnerabilities over time. - IP and company association search: Discover all IP addresses linked to a specific company domain, or run advanced IP searches using custom DSL queries for threat hunting and investigation. - Automated SQL-powered investigations: Execute SQL queries across hosts and IPs to extract targeted intelligence and spot trends or anomalies in your attack surface data. - Bulk static asset management: Add, update, or remove up to 1000 static asset rules at once to quickly adapt your security policies across projects. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `SECURITYTRAILS_BULK_STATIC_ASSET_RULES` | Bulk Static Asset Rules | Bulk add or remove static asset rules for a SecurityTrails ASI project. Static asset rules define which domains/IPs are included or excluded from the project's monitoring scope. This operation processes up to 1000 rules (combined add + remove) per request. The API processes rules asynchronously, waiting up to 2 seconds for completion. If processing takes longer, task_ids are returned for status polling. Note: Requires a valid project_id from the List Projects endpoint. Use the Get Static Assets endpoint to verify changes after bulk operations complete. | | `SECURITYTRAILS_GET_COMPANY_ASSOCIATED_IPS` | Get Company Associated IPs | Tool to retrieve IPs associated with a company domain. Use when you need to find all IP addresses linked to an organization's domain name. | | `SECURITYTRAILS_GET_DOMAIN` | Get Domain Details | Retrieves comprehensive domain information from SecurityTrails including current DNS records, infrastructure details, and statistics. This tool fetches detailed DNS data (A, AAAA, MX, NS, SOA, TXT records) along with metadata about when records were first seen, which organizations own the infrastructure, and how many other domains share the same servers. Useful for domain reconnaissance, infrastructure mapping, security analysis, and understanding domain configurations. Returns structured data with typed fields for easy programmatic access by AI agents. | | `SECURITYTRAILS_GET_DOMAIN_SSL` | Get Domain SSL | Tool to fetch current and historical SSL certificate details for a hostname. Use when you need to retrieve SSL data after identifying the domain. Coverage limited to certificates indexed by SecurityTrails; private, internally-issued, or very recently issued certificates may be absent. | | `SECURITYTRAILS_IP_SEARCH_STATISTICS` | IP Search Statistics | Fetch aggregated statistics for IP addresses matching a DSL query. Returns top open ports by frequency, common reverse DNS patterns, and total count. Useful for analyzing IP infrastructure patterns, port distributions, and PTR records across specific IP ranges or reverse DNS domains. | | `SECURITYTRAILS_LIST_PROJECTS` | List ASI Projects | Tool to list ASI projects available to the account. Use when you need project IDs for subsequent ASI operations. | | `SECURITYTRAILS_PING` | Ping | Tool to test authentication and connectivity with the SecurityTrails API. Use after configuring API key. | | `SECURITYTRAILS_SCROLL` | Scroll Results | Tool to continue scrolling through DSL search results. Use after receiving a scroll_id from SECURITYTRAILS_SEARCH_IPS or SECURITYTRAILS_SQL_API_EXECUTE_QUERY to fetch the next batch of data. Call iteratively until no scroll_id is returned to retrieve all pages. | | `SECURITYTRAILS_SEARCH_IPS` | Search IPs | Tool to search IP addresses via SecurityTrails DSL. Use when you need to filter IPs with custom DSL queries. Results are paginated; use SecurityTrails scroll mechanisms for large result sets to avoid missing assets. | | `SECURITYTRAILS_SQL_API_EXECUTE_QUERY` | SQL API Execute Query | Execute SQL-like queries against SecurityTrails data. Query the 'hosts' table for domain/DNS information or the 'ips' table for IP address/ASN/port data. Returns up to 100 records per request with a scroll ID for pagination. Supports standard SQL syntax (SELECT, WHERE, AND, OR, IN, IS NULL) but does NOT support LIMIT clause. | | `SECURITYTRAILS_SQL_API_SCROLL_RESULTS` | SQL API Scroll Results | Tool to fetch next page of SQL query results. Use after obtaining scroll_id from initial SQL API response. | | `SECURITYTRAILS_TEMP_SCRAPE_SECURITYTRAILS_USAGE` | Temp Scrape Securitytrails Usage | Retrieve account usage information from the SecurityTrails API. This action fetches the current monthly usage and allowed monthly usage limits for your SecurityTrails API account. Use this to monitor your API quota consumption. Returns: On success (200): - current_monthly_usage: Your current API usage for the month - allowed_monthly_usage: Your total allowed monthly API quota On error: - status_code: HTTP status code - response_text: Error message from API | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Securitytrails MCP server is an implementation of the Model Context Protocol that connects Claude Code (and other AI assistants like Claude and Cursor) directly to your Securitytrails account. It provides structured and secure access so Claude can perform Securitytrails operations on your behalf. With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster. ## Step-by-step Guide ### 1. Prerequisites Before starting, make sure you have: - Claude Pro, Max, or API billing enabled Anthropic account - Composio API Key - A Securitytrails account - Basic knowledge of Python or TypeScript ### 1. Install Claude Code To install Claude Code, use one of the following methods based on your operating system: ```bash # macOS, Linux, WSL curl -fsSL https://claude.ai/install.sh | bash # Windows PowerShell irm https://claude.ai/install.ps1 | iex # Windows CMD curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmd ``` ### 2. Set up Claude Code Open a terminal, go to your project folder, and start Claude Code: - Claude Code will open in your terminal - Follow the prompts to sign in with your Anthropic account - Complete the authentication flow - Once authenticated, you can start using Claude Code ```bash cd your-project-folder claude ``` ### 3. Set up environment variables Create a .env file in your project root with the following variables: - COMPOSIO_API_KEY authenticates with Composio (get it from [Composio dashboard](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=claude-code&utm_content=api_key&next=%2F~%2Forg%2Fconnect%2Fclients%2Fclaude-code)) - USER_ID identifies the user for session management (use any unique identifier) ```bash COMPOSIO_API_KEY=your_composio_api_key_here USER_ID=your_user_id_here ``` ### 4. Install Composio library No description provided. ```python pip install composio-core python-dotenv ``` ```typescript npm install @composio/core dotenv ``` ### 5. Generate Composio MCP URL No description provided. ```python import os from composio import Composio from dotenv import load_dotenv load_dotenv() COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") USER_ID = os.getenv("USER_ID") composio_client = Composio(api_key=COMPOSIO_API_KEY) composio_session = composio_client.create( user_id=USER_ID, toolkits=["securitytrails"], ) COMPOSIO_MCP_URL = composio_session.mcp.url print(f"MCP URL: {COMPOSIO_MCP_URL}") print(f"\nUse this command to add to Claude Code:") print(f'claude mcp add --transport http securitytrails-composio "{COMPOSIO_MCP_URL}" --headers "X-API-Key:{COMPOSIO_API_KEY}"') ``` ```typescript import 'dotenv/config'; import { Composio } from '@composio/core'; const { COMPOSIO_API_KEY, USER_ID } = process.env; if (!COMPOSIO_API_KEY || !USER_ID) { throw new Error('COMPOSIO_API_KEY and USER_ID required in .env'); } const composioClient = new Composio({ apiKey: COMPOSIO_API_KEY }); const composioSession = await composioClient.create(USER_ID, { toolkits: ['securitytrails'], }); const composioMcpUrl = composioSession?.mcp.url; console.log(`MCP URL: ${composioMcpUrl}`); console.log(`\nUse this command to add to Claude Code:`); console.log(`claude mcp add --transport http securitytrails-composio "${composioMcpUrl}" --headers "X-API-Key:${COMPOSIO_API_KEY}"`); ``` ### 6. Run the script and copy the MCP URL No description provided. ```python python generate_mcp_url.py ``` ```typescript node --loader ts-node/esm generate_mcp_url.ts # or if using tsx tsx generate_mcp_url.ts ``` ### 7. Add Securitytrails MCP to Claude Code In your terminal, add the MCP server using the command from the previous step. The command format is: - claude mcp add registers a new MCP server with Claude Code - --transport http specifies that this is an HTTP-based MCP server - The server name (securitytrails-composio) is how you'll reference it - The URL points to your Composio Tool Router session - --headers includes your Composio API key for authentication After running the command, close the current Claude Code session and start a new one for the changes to take effect. ```bash claude mcp add --transport http securitytrails-composio "YOUR_MCP_URL_HERE" --headers "X-API-Key:YOUR_COMPOSIO_API_KEY" # Then restart Claude Code exit claude ``` ### 8. Verify the installation Check that your Securitytrails MCP server is properly configured. - This command lists all MCP servers registered with Claude Code - You should see your securitytrails-composio entry in the list - This confirms that Claude Code can now access Securitytrails tools If everything is wired up, you should see your securitytrails-composio entry listed: ```bash claude mcp list ``` ### 9. Authenticate Securitytrails The first time you try to use Securitytrails tools, you'll be prompted to authenticate. - Claude Code will detect that you need to authenticate with Securitytrails - It will show you an authentication link - Open the link in your browser (or copy/paste it) - Complete the Securitytrails authorization flow - Return to the terminal and start using Securitytrails through Claude Code Once authenticated, you can ask Claude Code to perform Securitytrails operations in natural language. For example: - "Show all IPs linked to acme.com" - "Fetch SSL certificate history for example.com" - "Run SQL query for hosts in 192.168.0.0/16" ## Complete Code ```python import os from composio import Composio from dotenv import load_dotenv load_dotenv() COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") USER_ID = os.getenv("USER_ID") composio_client = Composio(api_key=COMPOSIO_API_KEY) composio_session = composio_client.create( user_id=USER_ID, toolkits=["securitytrails"], ) COMPOSIO_MCP_URL = composio_session.mcp.url print(f"MCP URL: {COMPOSIO_MCP_URL}") print(f"\nUse this command to add to Claude Code:") print(f'claude mcp add --transport http securitytrails-composio "{COMPOSIO_MCP_URL}" --headers "X-API-Key:{COMPOSIO_API_KEY}"') ``` ```typescript import 'dotenv/config'; import { Composio } from '@composio/core'; const { COMPOSIO_API_KEY, USER_ID } = process.env; if (!COMPOSIO_API_KEY || !USER_ID) { throw new Error('COMPOSIO_API_KEY and USER_ID required in .env'); } const composioClient = new Composio({ apiKey: COMPOSIO_API_KEY }); const composioSession = await composioClient.create(USER_ID, { toolkits: ['securitytrails'], }); const composioMcpUrl = composioSession?.mcp.url; console.log(`MCP URL: ${composioMcpUrl}`); console.log(`\nUse this command to add to Claude Code:`); console.log(`claude mcp add --transport http securitytrails-composio "${composioMcpUrl}" --headers "X-API-Key:${COMPOSIO_API_KEY}"`); ``` ## Conclusion You've successfully integrated Securitytrails with Claude Code using Composio's MCP server.

With a standalone Securitytrails MCP server, the agents and LLMs can only access a fixed set of Securitytrails tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Securitytrails and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Claude Code? Yes, you can. Claude Code fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Securitytrails tools. ### Can I manage the permissions and scopes for Securitytrails while using Tool Router? Yes, absolutely. You can configure which Securitytrails scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Securitytrails data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
