However, its capabilities are limited to the tools it has access to. Composio allows your OpenClaw to access Blocknative with authentication management handled for you. You can execute actions on Blocknative via your favorite OpenClaw interface (Telegram, WhatsApp, TUI, etc), whichever you prefer. ## Also integrate Blocknative with - [OpenAI Agents SDK](https://composio.dev/toolkits/blocknative/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/blocknative/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/blocknative/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/blocknative/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/blocknative/framework/codex) - [Hermes](https://composio.dev/toolkits/blocknative/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/blocknative/framework/cli) - [Google ADK](https://composio.dev/toolkits/blocknative/framework/google-adk) - [LangChain](https://composio.dev/toolkits/blocknative/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/blocknative/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/blocknative/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/blocknative/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/blocknative/framework/crew-ai) ## TL;DR ### Why use Composio? Apart from a managed and hosted MCP server, you will get: - 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 Blocknative to OpenClaw ### How to install Blocknative with OpenClaw ### Using Composio API Key and Setup Prompt - Go to [dashboard.composio.dev](https://dashboard.composio.dev/login?next=/~/org/connect/clients/openclaw&utm_source=toolkits&utm_medium=framework_template&utm_campaign=openclaw&utm_content=setup_prompt) - Copy the setup prompt - Run it in your OpenClaw chat interface. - Authenticate Blocknative from the [dashboard](https://dashboard.composio.dev/login?next=/~/org/connect/clients/openclaw&utm_source=toolkits&utm_medium=framework_template&utm_campaign=openclaw&utm_content=authenticate) - Go back to your OpenClaw interface and start asking questions. ### Using OpenClaw/Composio Plugin 1. Install OpenClaw Composio plugin ```bash openclaw plugins install @composio/openclaw-plugin ``` ## What is the Blocknative MCP server, and what's possible with it? The Blocknative MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Blocknative account. It provides structured and secure access to real-time mempool data and transaction management features across public blockchains, so your agent can monitor transactions, analyze gas prices, configure filters, and manage blockchain event subscriptions on your behalf. - Real-time mempool monitoring: Instruct your agent to subscribe to Ethereum transaction hashes or addresses and receive instant updates on their status and events. - Gas price analysis and estimation: Have your agent fetch current gas price distributions, base fee predictions, and inclusion probability estimates to help optimize transaction fees. - Customizable event filters: Let your agent configure advanced mempool filters and ABI decoding, so you can track only the events or transactions that matter to your workflow. - Multichain event subscriptions: Enable your agent to subscribe or unsubscribe to transaction and account events across multiple supported blockchains using the Blocknative multichain SDK. - Supported chain discovery: Ask your agent to list and discover which blockchains and gas oracles are available for monitoring and analytics. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `BLOCKNATIVE_CONFIGURE_FILTERS` | Configure Mempool Filters | Tool to configure filters and ABI decoding for Ethereum mempool transactions. Use after establishing a Blocknative WebSocket connection to set up event filters and decoding. | | `BLOCKNATIVE_GET_GAS_DISTRIBUTION` | Get Gas Price Distribution | Tool to retrieve the current mempool gas price distribution breakdown. Use when analyzing gas price trends or preparing fee strategies. | | `BLOCKNATIVE_GET_GAS_ORACLES` | Get Gas Oracles | Tool to retrieve metadata on supported gas oracles per chain. Use when you need to dynamically discover all available on-chain gas estimation oracles across networks. | | `BLOCKNATIVE_GET_GAS_PRICES` | Get Gas Prices | Tool to fetch gas price estimates for specific inclusion probabilities. Use when you need gas price ranges for the next block or next ~10 seconds. | | `BLOCKNATIVE_GET_SUPPORTED_CHAINS` | Get Supported Chains | Tool to retrieve supported chains metadata. Use when discovering available networks for Blocknative gas services. | | `BLOCKNATIVE_PREDICTION_API_BASEFEE_ESTIMATES` | Get Base Fee Estimates | Get real-time gas fee predictions for Ethereum mainnet's next 5 blocks. Returns base fee, blob base fee, and priority fee estimates at multiple confidence levels (99% and 50%). Essential for optimizing transaction costs and timing. Predictions include current block context (block number, time since last block) and estimated fees in gwei. | | `BLOCKNATIVE_SUBSCRIBE_MULTICHAIN` | Subscribe Multichain | Generate WebSocket connection details to subscribe to real-time blockchain events (transactions or account activity) across multiple chains via Blocknative's Multichain API. Returns the WebSocket URL and subscription message payload needed to establish the connection and start receiving event notifications for a specific transaction hash or account address on any supported blockchain. | | `BLOCKNATIVE_SUBSCRIBE_TRANSACTION_HASH` | Subscribe Transaction Hash | Tool to subscribe to transaction state change events of an Ethereum transaction hash. Use after establishing a Blocknative WebSocket connection to prepare the subscription message. | | `BLOCKNATIVE_UNSUBSCRIBE_MULTICHAIN` | Unsubscribe Multichain | Tool to unsubscribe from events across multiple chains using the Multichain SDK.

With a standalone Blocknative MCP server, the agents and LLMs can only access a fixed set of Blocknative tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Blocknative and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with OpenClaw? Yes, you can. OpenClaw 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 Blocknative tools. ### Can I manage the permissions and scopes for Blocknative while using Tool Router? Yes, absolutely. You can configure which Blocknative 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 Blocknative data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) ยท [Composio docs](https://docs.composio.dev/llms.txt)
