"How to use remote URLs with SSE without local files" matching MCP servers:

A local MCP server for handling X402 payment-protected HTTP endpoints, offering tools for order placement, signing, and payment submission with multiple signing modes and blockchain networks.

Enables AI agents to sign Geode blockchain transactions on the user's own machine, with keys that never leave it, by independently decoding and verifying each server-prepared transaction before approving it. Refuses anything outside allowed Geode app actions or beyond the configured per-transaction, daily, and storage-deposit GEODE limits.

MCP server for verifying and attesting SHA-256 fingerprints of digital works via Streamable HTTP, with zero-install and privacy-preserving design.

A Model Context Protocol (MCP) server that provides tools and resources for AI agents to interact with the Algorand blockchain.

An SSE (Server-Sent Events) server that leverages OKX DEX SDK to support DEX trading operations on Solana blockchain and cross-chain bridge transactions.

Enables interaction with Binance Smart Chain, including wallet management, token transfers, contract execution, PancakeSwap swaps, and four.meme token creation.

Generates MCP servers from smart contract ABIs, enabling Claude to interact with any Ethereum contract via natural language commands.

Provides a pre-signature payment-risk verdict (GO/HOLD/STOP) for x402 payments based on counterparty reputation, price anomaly, and OFAC sanctions.

Provides enriched blockchain data from Codex for use with MCP-compatible clients like Claude Desktop.

Enables AI agents and MCP hosts to anchor file hashes to Bitcoin via OpenTimestamps and verify proofs, ensuring files existed before a given time with privacy-preserving local hashing.

A local MCP proxy that connects to remote MCP servers and automatically handles x402 payments, signing USDC on-chain when a tool returns HTTP 402.

An MCP server whose tool invocations are metered and charged over x402, plus a paying-proxy reference client that lets any standard MCP client use the paid tool without knowing x402 exists.

Use the microservice of testraptor

Remote MCP server enabling agents to search, buy, and publish reusable knowledge via nine agent-native tools without API keys or custodied wallets.

A local signing MCP server that lets Claude Code use private keys without ever exposing key material to the model's context window.

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 MCP clients like Claude and Cursor to protect local files with SELLAT proofs of existence, track their Polygon and Bitcoin anchoring status, add a qualified eIDAS timestamp seal, and verify files against proof files or evidence packages. Files are hashed on the user's machine, so only the SHA-256 hash is sent to the service.

Manages Algorand signer records, enforces local signing policy, and signs payloads without network access.

Enables AI agents to use pay-per-use web scraping, Base blockchain analytics, and PDF text extraction tools, monetized via x402 USDC micropayments.

mcp server that allows to do actual actions related to solana first version adds knowledge about RPC methods and how to call them
