"Local" matching MCP servers:

MCP server for local transaction signing across EVM, UTXO, Tron, and XRP blockchains, with no network calls or API keys required.

Local MCP-to-browser signing bridge for EVM, Solana, and Sui, letting agents prepare and simulate transactions while users approve and sign in a browser wallet extension.

Unifies 11 protocol specification repositories (EIPs, BIPs, CIPs, etc.) and canonical contract addresses across 10 chains into a local FTS5 index, enabling coding agents to retrieve exact spec text and contract addresses via natural language queries.

Enables users to compare current Aerodrome veNFT voting positions, bounded claimable rewards, and selected pools' voting evidence on Base against a saved local baseline, with retryable, atomically stored change reports. All tools are read-only on chain, requiring no keys, signing, or transactions.

Enables AI agents and terminal users to discover Solana Gibwork bounties, inspect deliverable requirements, verify on-chain escrow and token mints, and scaffold local development workspaces.

Enables MCP clients to connect to Walrus Memory for persistent memory operations like remember, recall, analyze, and restore, with browser-based wallet login and local credential storage.

MCP server for Ethereum Swarm decentralized storage. Provides 12 tools for uploading and downloading data and files, managing postage stamp batches, and working with Swarm feeds — all via the Bee API. Works with the public Swarm gateway or a local Bee node.

A local-first MCP server that enables AI agents to query the Sui blockchain using gRPC, GraphQL, and Archival Service, with auto-routing and LLM-friendly responses.

A secure local DID signer for AmikoNet that manages private keys and creates cryptographic signatures for decentralized authentication. Supports Ed25519, Solana, and EVM chains while ensuring private keys never leave your local machine.

A local MCP server that enables AI tools to query Obyte blockchain data including balances, units, autonomous agent state and dry runs, and token symbols, supporting both mainnet and testnet.

Enables AI agents to perform Bitcoin and Lightning Network payments using a non-custodial, zero-trust architecture. It provides 13 tools for wallet management, invoice creation, and payment processing while keeping node credentials local to the user's machine.

A local Ethereum contract analysis tool that retrieves on-chain information, integrates Etherscan and RPC data, and automatically executes view functions to provide comprehensive contract insights.

Enables secure interaction with blockchain smart contracts across multiple chains, including ABI analysis, contract method invocation (view/nonpayable/payable), and local wallet management for Ethereum and Base networks.

Enables personal agents to access Solana market data and execute token swaps via the Dritan SDK while maintaining local wallet security. It provides tools for wallet management, real-time token price tracking, and secure transaction signing and broadcasting.

Deep Research for crypto - free & fully local 🧠

Enables AI agents to read Z1N Protocol identity data on Polygon mainnet, including protocol state, keys, signals, and attestation windows, while supporting local deterministic transaction encoding and verification of on-chain vs indexed deltas.

Enables AI agents to securely manage a non-custodial wallet with locally encrypted seed phrases, supporting balance checks, local signing, token transfers, swaps, and interactions across 10+ blockchain networks.

Enables secure management of Squads multisig accounts on the Solana blockchain, allowing LLMs to create proposals, vote, and manage assets. It features built-in security auditing and local private key storage to ensure safe interaction with multisig configurations.

Enables ChatGPT and Codex to request public keys, prepare and sign exact Nostr events, encrypt or decrypt NIP-04/NIP-44 payloads, and publish with per-relay acknowledgement, while the private key stays in the user's Alby, nos2x, or remote NIP-46 signer. Every operation is queued for local browser approval, with one-use signing intents and verification before anything is broadcast.

Enables ChatGPT to interact with multiple blockchain networks for reading balances and managing wallet operations through a non-custodial local vault and policy engine.
