Blocknative MCP server

Connect Blocknative to Claude, ChatGPT, Cursor, Claude Code, Codex, Gemini, GitHub Copilot and any other MCP client, for your whole team. Metorial adds security, governance, and tracing, and gives everyone one Magic MCP URL to connect.

What you can do with the Blocknative MCP server

Ask your agent in plain language. Each of these maps to a real tool on the server.

  • Use the decode l2 batch tool in Blocknative
  • Use the estimate gas price tool in Blocknative
  • Use the get blob tool in Blocknative
  • Use the list gas oracles tool in Blocknative
  • Use the get gas distribution tool in Blocknative
  • Use the predict base fee tool in Blocknative

Supported Tools

decode_l2_batch

Decode L2 Batch

Decodes an Ethereum L2 batch transaction into human-readable format. Accepts an L1 transaction hash of a batch (pending or confirmed) and returns decoded calldata and blobdata. Supports Optimism, Base, zkSync, Arbitrum, Mode, Zora, Kroma, and Blast batches.

estimate_gas_price

Estimate Gas Price

Estimates the gas price needed for a transaction to be included within the chain-specific prediction horizon. Returns confidence-based predictions for both pre-EIP-1559 (Type 0) and EIP-1559 (Type 2) transactions. Supports custom confidence levels and chain selection via chain ID or system/network identifiers. Use list_supported_chains to discover chain metadata.

get_blob

Get Blob

Retrieves archived Ethereum blob data by versioned hash. Returns the commitment, proof, byte counts, and optionally the full blob data. Stores all blobs that entered the Ethereum mempool (confirmed or not), providing access to historical blob data beyond Ethereum's ~18-day ephemeral storage window.

list_gas_oracles

List Gas Oracles

Lists all on-chain gas estimation oracle contracts supported by Blocknative. Returns metadata including oracle contract addresses by version, RPC URLs, and block explorer links for each supported chain. Useful for interacting with on-chain gas oracles directly.

get_gas_distribution

Get Gas Distribution

Retrieves the current distribution and breakdown of gas prices in the Ethereum mempool. Shows the gas prices of the top N transactions eligible for inclusion in the next block. Useful for understanding current mempool pressure and transaction pricing dynamics.

predict_base_fee

Predict Base Fee

Predicts the Ethereum base fee and blob base fee for the next 5 blocks at the confidence levels returned by the provider. Uses a quantile regression neural network model for predictions. Useful for setting optimal gas fees on Ethereum transactions.

list_supported_chains

List Supported Chains

Lists all blockchain networks supported by Blocknative with their metadata including chain ID, architecture, available features, and system/network identifiers. Use this to discover which chains are available for gas estimation and other Blocknative services.

Connect Blocknative to your AI client

Every client uses the same Magic MCP URL, and so does any other MCP client. Add it once and sign in with SSO.

  1. Enable Blocknative in Metorial. In your Metorial portal, enable the Blocknative MCP server and sign in with the account that owns the data. Access stays governed by your team policies.
  2. Add a custom connector. Open Customize, then Connectors. Select Add, then Custom, then Web.
  3. Paste your Metorial MCP URL. Name it Metorial, paste your Magic MCP URL (<your-magic-mcp-url>) and continue.
  4. Sign in. Select Add and sign in to load Blocknative tools.

Run Blocknative through the Metorial gateway

One governed layer for every app your agents reach, not a separate connector per tool.

  • Give Blocknative and every other app to your whole team through one MCP gateway, behind your SSO.
  • Scope which teams and agents can use Blocknative tools with role-based access control, and trace every call.
  • Prefer to run it yourself? Metorial is open source and self-hostable.

Frequently asked questions

Common questions about connecting Blocknative to AI agents with Metorial.

  1. How many tools does the Blocknative MCP server have?
    The Blocknative MCP server exposes 7 tools, including Decode L2 Batch, Estimate Gas Price, Get Blob. Each one is governed and traced through Metorial.
  2. Blocknative exposes tools your agents call on demand; it does not publish event triggers yet. Everything still runs through one governed MCP URL.
  3. Any MCP client, including VS Code, Windsurf, Zed, OpenCode and Grok. Each one reaches the Blocknative MCP server through the same Metorial URL.
  4. Use role-based access control to decide which teams, users, and agents can use Blocknative and which of its tools they can call.
  5. Yes. Metorial is open source, so you can run the Blocknative MCP server yourself or use the hosted gateway.
