Restart Cursor. 105 | 106 | ## Usage in Claude 107 | 108 | Once configured, you can ask Claude to use the Nostr tools by making requests like: 109 | 110 | - "Show me the profile information for npub1qny3tkh0acurzla8x3zy4nhrjz5zd8ne6dvrjehx9n9hr3lnj08qwuzwc8" 111 | - "What are the recent posts from npub1qny3tkh0acurzla8x3zy4nhrjz5zd8ne6dvrjehx9n9hr3lnj08qwuzwc8?" 112 | - "Show me the long-form articles from npub1qny3tkh0acurzla8x3zy4nhrjz5zd8ne6dvrjehx9n9hr3lnj08qwuzwc8" 113 | - "How many zaps has npub1qny3tkh0acurzla8x3zy4nhrjz5zd8ne6dvrjehx9n9hr3lnj08qwuzwc8 received?" 114 | - "Show me the zaps sent by npub1qny3tkh0acurzla8x3zy4nhrjz5zd8ne6dvrjehx9n9hr3lnj08qwuzwc8" 115 | - "Show me all zaps (both sent and received) for npub1qny3tkh0acurzla8x3zy4nhrjz5zd8ne6dvrjehx9n9hr3lnj08qwuzwc8" 116 | - "Search for NIPs about zaps" 117 | - "What NIPs are related to long-form content?" 118 | - "Show me NIP-23 with full content" 119 | - "Send an anonymous zap of 100 sats to npub1qny3tkh0acurzla8x3zy4nhrjz5zd8ne6dvrjehx9n9hr3lnj08qwuzwc8" 120 | - "Send 1000 sats to note1abcdef... with a comment saying 'Great post!'" 121 | 122 | The server automatically handles conversion between npub and hex formats, so you can use either format in your queries. Results are displayed with user-friendly npub identifiers. 123 | 124 | ## Advanced Usage 125 | 126 | You can specify custom relays for any query: 127 | 128 | - "Show me the profile for npub1qny3tkh0acurzla8x3zy4nhrjz5zd8ne6dvrjehx9n9hr3lnj08qwuzwc8 using relay wss://relay.damus.io" 129 | 130 | You can also specify the number of notes or zaps to fetch: 131 | 132 | - "Show me the latest 20 notes from npub1qny3tkh0acurzla8x3zy4nhrjz5zd8ne6dvrjehx9n9hr3lnj08qwuzwc8" 133 | 134 | For anonymous zaps, you can include optional comments and specify the target type: 135 | 136 | - "Send an anonymous zap of 500 sats to note1abcdef... with the comment 'Great post!'" 137 | - "Send 1000 sats anonymously to nevent1qys... using relay wss://relay.damus.io" 138 | 139 | For zap queries, you can enable extra validation and debugging: 140 | 141 | - "Show me all zaps for npub1qny3tkh0acurzla8x3zy4nhrjz5zd8ne6dvrjehx9n9hr3lnj08qwuzwc8 with validation and debug enabled" 142 | 143 | For NIP searches, you can control the number of results and include full content: 144 | 145 | - "Search for NIPs about zaps with full content" 146 | - "Show me the top 5 NIPs about relays" 147 | - "What NIPs are related to encryption? Show me 15 results" 148 | 149 | ## Limitations 150 | 151 | - The server has a default 8-second timeout for queries to prevent hanging 152 | - Only public keys in hex format or npub format are supported 153 | - Only a subset of relays is used by default 154 | 155 | ## Implementation Details 156 | 157 | - Native support for npub format using NIP-19 encoding/decoding 158 | - NIP-57 compliant zap receipt detection with direction-awareness (sent/received/self) 159 | - Advanced bolt11 invoice parsing with payment amount extraction 160 | - Smart caching system for improved performance with large volumes of zaps 161 | - Total sats calculations for sent/received/self zaps with net balance 162 | - Optional NIP-57 validation for ensuring zap receipt integrity 163 | - Anonymous zap support with lightning invoice generation 164 | - Support for zapping profiles, events (note IDs), and replaceable events (naddr) 165 | - Each tool call creates a fresh connection to the relays, ensuring reliable data retrieval 166 | 167 | ## Anonymous Zaps 168 | 169 | The `sendAnonymousZap` tool lets users send zaps without revealing their Nostr identity. Key points about anonymous zaps: 170 | 171 | - The zap will appear to come from an anonymous user in the recipient's wallet 172 | - The zap follows the NIP-57 protocol but without a sender signature 173 | - The recipient can still receive the payment and any included message 174 | - You can zap profiles (using npub/hex pubkey), specific events (using note/nevent/hex ID), or replaceable events (using naddr) 175 | - The server generates a lightning invoice for payment that you can copy into your Lightning wallet 176 | 177 | Examples: 178 | ``` 179 | "Send an anonymous zap of 100 sats to npub1qny3tkh0acurzla8x3zy4nhrjz5zd8ne6dvrjehx9n9hr3lnj08qwuzwc8" 180 | "Send 1000 sats anonymously to note1abcdef... with the comment 'Great post!'" 181 | ``` 182 | 183 | The server fully validates LNURL services according to LNURL-pay (LUD-06) and Lightning Address (LUD-16) specifications, ensuring compatibility with various wallet implementations. 184 | 185 | ## Troubleshooting 186 | 187 | - If queries time out, try increasing the `QUERY_TIMEOUT` value in the source code (currently 8 seconds) 188 | - If no data is found, try specifying different relays that might have the data 189 | - Check Claude's MCP logs for detailed error information 190 | 191 | ## Default Relays 192 | 193 | The server uses the following relays by default: 194 | - wss://relay.damus.io 195 | - wss://relay.nostr.band 196 | - wss://relay.primal.net 197 | - wss://nos.lol 198 | - wss://relay.current.fyi 199 | - wss://nostr.bitcoiner.social 200 | 201 | ## Development 202 | 203 | To modify or extend this server: 204 | 205 | 1. Edit the relevant file: 206 | - `index.ts`: Main server and tool registration 207 | - `note/note-tools.ts`: Profile and notes functionality ([Documentation](./note/README.md)) 208 | - `zap/zap-tools.ts`: Zap-related functionality ([Documentation](./zap/README.md)) 209 | - `nips/nips-tools.ts`: Functions for searching NIPs ([Documentation](./nips/README.md)) 210 | - `utils/`: Shared utility functions 211 | - `constants.ts`: Global constants and relay configurations 212 | - `conversion.ts`: Pubkey format conversion utilities 213 | - `formatting.ts`: Output formatting helpers 214 | - `pool.ts`: Nostr connection pool management 215 | - `ephemeral-relay.ts`: In-memory Nostr relay for testing 216 | 217 | 2. Run `npm run build` to compile 218 | 219 | 3. Restart Claude for Desktop or Cursor to pick up your changes 220 | 221 | ## Testing 222 | 223 | We've implemented a comprehensive test suite using Jest to test both basic functionality and integration with the Nostr protocol: 224 | 225 | ```bash 226 | # Run all tests 227 | npm test 228 | 229 | # Run a specific test file 230 | npm test -- __tests__/basic.test.ts 231 | 232 | # Run integration tests 233 | npm test -- __tests__/integration.test.ts 234 | ``` 235 | 236 | The test suite includes: 237 | 238 | ### Unit Tests 239 | - `basic.test.ts` - Tests simple profile formatting and zap receipt processing 240 | - `profile-notes-simple.test.ts` - Tests profile and note data structures 241 | - `zap-tools-simple.test.ts` - Tests zap processing and anonymous zap preparation 242 | 243 | ### Integration Tests 244 | - `integration.test.ts` - Tests interaction with an ephemeral Nostr relay including: 245 | - Publishing profile events 246 | - Creating and retrieving text notes 247 | - Publishing zap receipts 248 | - Filtering events 249 | 250 | - `websocket-integration.test.ts` - Tests WebSocket communication with a Nostr relay: 251 | - Publishing events over WebSocket 252 | - Subscribing to events with filters 253 | - Managing multiple subscriptions 254 | - Closing subscriptions 255 | - Verifying that events with invalid signatures are rejected 256 | 257 | All integration tests use our `ephemeral-relay.ts` implementation—a fully functional in-memory Nostr relay that supports the Nostr protocol, allowing for real cryptographic event signing and verification without requiring external network connections. This provides a robust way to test the full Nostr workflow in an isolated environment. 258 | 259 | For more details about the test suite, see [__tests__/README.md](./__tests__/README.md). 260 | 261 | ## Codebase Organization 262 | 263 | The codebase is organized into modules: 264 | - Core server setup in `index.ts` 265 | - Specialized functionality in dedicated directories: 266 | - [`nips/`](./nips/README.md): NIPs search and caching functionality 267 | - [`note/`](./note/README.md): Profile and notes functionality 268 | - [`zap/`](./zap/README.md): Zap handling and anonymous zapping 269 | - Common utilities in the `utils/` directory 270 | 271 | This modular structure makes the codebase more maintainable, reduces duplication, and enables easier feature extensions. For detailed information about each module's features and implementation, see their respective documentation. 272 | -------------------------------------------------------------------------------- /__tests__/README.md: -------------------------------------------------------------------------------- 1 | # Nostr MCP Server Test Suite 2 | 3 | This directory contains tests for the Nostr MCP server functionality. 4 | 5 | ## Overview 6 | 7 | The test suite uses Jest to test both the core functionality and protocol integration of the Nostr MCP server. It includes: 8 | 9 | 1. Unit Tests - Testing isolated business logic 10 | 2. Integration Tests - Testing with a real (but in-memory) Nostr relay 11 | 12 | ## Test Files 13 | 14 | ### Unit Tests 15 | - `basic.test.ts`: Simple tests for profile formatting and zap receipt processing 16 | - `profile-notes-simple.test.ts`: Tests for profile and note data structures 17 | - `zap-tools-simple.test.ts`: Tests for zap processing and anonymous zap preparation 18 | - `mocks.ts`: Contains mock data for unit tests 19 | 20 | ### Integration Tests 21 | - `integration.test.ts`: Tests direct interaction with an ephemeral Nostr relay 22 | - `websocket-integration.test.ts`: Tests WebSocket communication with a Nostr relay 23 | 24 | ## Running Tests 25 | 26 | To run all tests: 27 | 28 | ```bash 29 | npm test 30 | ``` 31 | 32 | To run a specific test file: 33 | 34 | ```bash 35 | npm test -- __tests__/basic.test.ts 36 | npm test -- __tests__/integration.test.ts 37 | ``` 38 | 39 | ## Test Design 40 | 41 | The tests use two approaches: 42 | 43 | ### Unit Tests 44 | Unit tests use mocks to simulate the Nostr network and focus on testing business logic without actual network communication. This approach allows for: 45 | - Fast test execution 46 | - Deterministic behavior 47 | - Testing error handling and edge cases 48 | 49 | ### Integration Tests 50 | Integration tests use an in-memory ephemeral relay that implements the Nostr protocol, allowing: 51 | - Testing with real cryptographically signed events 52 | - Full event publication and retrieval workflows 53 | - Testing WebSocket protocol communication 54 | - Validating event verification works properly 55 | 56 | ## Test Coverage 57 | 58 | The test suite provides coverage for: 59 | 60 | - Profile retrieval and formatting 61 | - Note retrieval and formatting 62 | - Zap receipt processing and validation 63 | - Anonymous zap preparation 64 | - Full Nostr protocol event cycles 65 | - WebSocket communication 66 | - Event filtering 67 | - Subscription management 68 | 69 | ## Adding Tests 70 | 71 | When adding new features, consider adding: 72 | 73 | 1. Unit tests that: 74 | - Test the business logic in isolation 75 | - Verify error handling 76 | - Test edge cases 77 | 78 | 2. Integration tests that: 79 | - Verify the feature works with real Nostr events 80 | - Test the WebSocket protocol behavior if applicable 81 | - Verify end-to-end workflows -------------------------------------------------------------------------------- /__tests__/basic.test.ts: -------------------------------------------------------------------------------- 1 | import { jest } from '@jest/globals'; 2 | 3 | // Define a simple profile type for testing 4 | type NostrProfile = { 5 | id: string; 6 | pubkey: string; 7 | created_at: number; 8 | kind: number; 9 | tags: string[][]; 10 | content: string; 11 | sig: string; 12 | }; 13 | 14 | // Define a simple zap receipt type 15 | type ZapReceipt = { 16 | id: string; 17 | pubkey: string; 18 | created_at: number; 19 | kind: number; 20 | tags: string[][]; 21 | content: string; 22 | sig: string; 23 | }; 24 | 25 | // Mock the formatProfile function 26 | const mockFormatProfile = jest.fn((profile: NostrProfile) => { 27 | const content = typeof profile.content === 'string' 28 | ?

The cache includes: 34 | 35 | - Full NIP contents and metadata 36 | - Search indices for efficient lookups 37 | - Last updated timestamp 38 | 39 | This caching strategy minimizes API calls to GitHub while ensuring reasonably up-to-date information. 40 | 41 | ## Performance Enhancements 42 | 43 | The NIPs module includes several performance optimizations: 44 | 45 | - **Persistent Caching**: NIPs are cached to disk (with 24-hour TTL) to reduce GitHub API usage 46 | - **Smart Search Indexing**: Two-pass indexing system for faster search and reduced memory usage 47 | - **Conditional HTTP Requests**: Uses If-Modified-Since headers to minimize unnecessary data transfers 48 | - **Exponential Backoff**: Implements backoff with jitter for more reliable GitHub API requests 49 | - **Request Timeouts**: Uses AbortController to avoid hanging requests 50 | - **Pre-filtering Optimization**: Identifies potential matches before scoring for faster searches 51 | - **Batch Processing**: Processes GitHub API requests in controlled batches with proper error handling 52 | - **Safe File Operations**: Uses atomic write operations to prevent cache corruption 53 | - **MCP-Friendly Logging**: All logs use console.error to avoid interfering with stdout JSON communication 54 | 55 | These enhancements ensure reliable operation even with intermittent connectivity or API rate limiting. -------------------------------------------------------------------------------- /nips/nips-tools.ts: -------------------------------------------------------------------------------- 1 | import { z } from "zod";

33 | 34 | // Format a zap for display 35 | const formattedZap = formatZapReceipt(zap, contextPubkey); 36 | 37 | // Prepare an anonymous zap (returns a lightning invoice) 38 | const zapResult = await prepareAnonymousZap(targetNpub, 1000, "Great post!"); 39 | ``` 40 | 41 | ## Core Data Structures 42 | 43 | The module defines several key interfaces and types: 44 | 45 | - `ZapReceipt`: Represents a NIP-57 zap receipt (kind 9735) 46 | - `ZapRequest`: Represents a NIP-57 zap request (kind 9734) 47 | - `ZapDirection`: Enum for zap directions ('sent', 'received', 'self', 'unknown') 48 | - `CachedZap`: Enhanced zap receipt with additional metadata 49 | - `LnurlPayResponse`: LNURL-pay service response with zap capabilities 50 | - `LnurlCallbackResponse`: Response from LNURL-pay callback with invoice 51 | 52 | This structure enables robust processing and tracking of zap-related events on the Nostr network. -------------------------------------------------------------------------------- /zap/zap-tools.ts: -------------------------------------------------------------------------------- 1 | import { z } from "zod";
