This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Securitytrails account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## 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 Code](https://composio.dev/toolkits/securitytrails/framework/claude-code) - [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) - [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) - [Pydantic AI](https://composio.dev/toolkits/securitytrails/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/securitytrails/framework/autogen) ## TL;DR ### How Atomic Agent connects to Securitytrails Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication. Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account. ## Connect Securitytrails to Atomic Agent ### Connect Securitytrails to Atomic Agent - Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key. - In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart. - Ask Atomic Agent to do something in Securitytrails. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Securitytrails account, then return to Atomic Agent to continue. ### Headless setup Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file. ```bash COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY ``` ## 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. ## Troubleshooting ### Why is my API key rejected? Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying. ### Why are Composio tools unavailable after saving a key? Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk. ### Does Composio have a free plan? The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection. ## Complete Code None listed. ## Conclusion ### Use Securitytrails from Atomic Agent With your account connected, ask Atomic Agent to work with Securitytrails in natural language. You can connect more apps through the same Composio integration as you need them.

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 Atomic Agent? Yes, you can. Atomic Agent 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)
