Nostr MCP Server

Nostr MCP Server is an MCP server that provides decentralized Nostr protocol capabilities to large language models. Built to connect AI agents to the Nostr network, it allows LLMs to interact with decentralized social channels directly through standard MCP interfaces. Developers and autonomous agent creators use this server to read, write, and manage interactions over Nostr relays. The server provides 40 distinct tools covering essential protocol interactions including managing user profiles, publishing text notes, organizing relay connections, handling direct messages, and processing zaps. Note that this specific repository has been archived and superseded by nostr-agent-interface, which expands functionality with additional blob storage and updated tools. Nevertheless, Nostr MCP Server establishes the core protocol foundation enabling AI clients to engage seamlessly with decentralized messaging, social feeds, and cryptographic identities without proprietary social media API restrictions.

How to install and configure Nostr MCP Server

1. Note that this repository is superseded by nostr-agent-interface. To install the active successor package globally, run: bash npm install -g nostr-agent-interface 2. Alternatively, build directly from source: bash git clone https://github.com/AustinKelsay/nostr-agent-interface.git cd nostr-agent-interface npm install && npm run build 3. Configure the server executable inside your MCP client configuration file (such as Claude Desktop or Cursor). Refer to the repository documentation at https://github.com/austinkelsay/nostr-mcp-server for additional setup details.

What you can do with Nostr MCP Server

• Publishing automated status updates, articles, and short-form text notes across multiple decentralized Nostr relays. - Monitoring and reading Nostr feeds, mentions, and user profiles directly within an AI chat interface. - Sending, decrypting, and organizing direct messages between Nostr public keys using automated assistant logic. - Managing relay connection lists and querying decentralized metadata for verified Nostr identities and profiles. - Processing and responding to Lightning Network zaps and social tipping events through automated agent rules.
