"How to Read and Write Excel Files" matching MCP servers:

A read-only MCP server for AI agents to access Nostr profiles, notes, search, and relay lists through user-chosen relays, without requiring an account or keys.

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

MCP server for Chainlink Runtime Environment, enabling build, simulate, deploy, and manage CRE workflows from any MCP client.

Enables AI agents to read and bid on a paid message slot on Solana, with enforced spend limits, dry-run proposals, and an append-only audit log for every write.

Teaches AI coding agents how to reason correctly about MetaMask Embedded Wallets / Web3Auth architecture, SDK choice, key derivation, auth flows, and common integration pitfalls.

Read-only access to the live NOVAI blockchain (an AI-native L1) over public JSON-RPC. Query blocks, transactions, AI entities, on-chain signals, oracle anchors, and memory objects. No keys, no write paths.

MCP server for Shelby Protocol that enables AI agents to read, write, and manage files on decentralized storage (Aptos) through tools like upload, download, list, delete, and account info.

Enables agents to read and write technocore.chat messages with a did:key identity, including end-to-end encrypted rooms, via 14 tools over stdio.

Enables LLMs to read and write the BSV social graph with an on-chain identity, OS-keychain wallet, and 38 tools for posts, replies, follows, messages, payments, profiles, and more, with every write broadcast as a real BSV mainnet transaction visible across 50+ shared apps.

Enables read and write interactions with 60+ blockchain networks through Claude Desktop, providing a standardized multi-chain API for transaction management, account insights, staking, and token interactions.

Enables AI agents to read chain data, execute transactions, swap tokens, and manage wallets on Solana through 38 tools across 7 modules. Supports write operations with a private key and includes built-in prompts for common workflows.

Identity + memory layer for AI agents on the Emercoin blockchain — read open, write via GitHub OAuth

Enables interaction with Ethereum-compatible smart contracts through their ABI, allowing both read operations (querying state) and write operations (executing transactions) dynamically based on the contract's interface.

A minimal demo of the x402 payment protocol protecting an MCP tool endpoint, showing how to charge for MCP tools using real 402 rejections and testnet payments.

Enables AI assistants to invoke generated NostrHost operations over MCP, with read operations executed immediately and write operations gated on approval. Client authentication uses NIP-98, results are redacted, and the HTTP transport binds to loopback only.

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

Enables read and write access to the Celo blockchain including balance checks, token transfers, swaps, agent identity (ERC-8004), and x402 micropayments, returning unsigned transactions for user signing.

Exposes OriginTrail DKG V10 working, shared, and verifiable memory as standard MCP tools, enabling users to read, write, share, and query DKG memory from any MCP-capable client without custom HTTP wiring.

Read-only on-chain query surface for the AgentCivics civil registry on Sui — soulbound AI-agent identities, on-chain memories, reputation, refusal records. Hosted, no install, no keypair. For write tools (register, write_memory, record_refusal), install the npm package @agentcivics/mcp-server locally and supply your own keypair.

An MCP server that gives autonomous coding agents deterministic, schema-validated tools for EVM smart contract development — security scanning, gas profiling, compiler diagnostics, and transaction simulation.
