# Stellar MCP Server for XDR An [Model Context Protocol (MCP)] server that decodes Stellar XDR into XDR-JSON, that agents can use to understand what XDR means. [Model Context Protocol (MCP)]: https://www.claudemcp.com/ Provides five tools: - `mcp_stellar-xdr_types` - Get the supported XDR types. - `mcp_stellar-xdr_json_schema` - Get the JSON schema for an XDR type. - `mcp_stellar-xdr_guess` - Guess what type Stellar XDR is, getting back a list of possible types. - `mcp_stellar-xdr_decode` - Decode a Stellar XDR to JSON. - `mcp_stellar-xdr_encode` - Encode a Stellar XDR from JSON. ## Usage (General) To use with agents, setup a `stdio` MCP configuration with your agent calling the following command: ``` { "command": "npx", "args": ["deno", "run", "--allow-read", "https://github.com/leighmcculloch/mcp-stellar-xdr/raw/refs/heads/main/mcp-stellar-xdr.ts"] } ``` If you have `deno` installed you can omit the `npx` command and call `deno` directly. ## Usage (Claude Desktop) To use with Claude Desktop: 1. Add the server config: On macOS: `~/Library/Application Support/Claude/claude_desktop_config.json` On Windows: `%APPDATA%/Claude/claude_desktop_config.json` ```json { "mcpServers": { "mcp-stellar-xdr-json": { "command": "npx", "args": [ "deno", "run", "--allow-read", "https://github.com/leighmcculloch/mcp-stellar-xdr/raw/refs/heads/main/mcp-stellar-xdr.ts" ] } } } ``` 2. Reopen Claude Desktop. ## Usage (Claude Code) 1. Add the server config: ``` claude mcp add \ --transport stdio \ --scope user \ mcp-stellar-xdr \ -- \ npx deno run --allow-read https://github.com/leighmcculloch/mcp-stellar-xdr/raw/refs/heads/main/mcp-stellar-xdr.ts ``` 2. Reopen Claude Code. ## Example ### Understanding a Transaction https://github.com/user-attachments/assets/8c4eef81-9109-432d-8be6-8e24ead74eef ### Understanding a Contract Event https://github.com/user-attachments/assets/91523c7e-652e-46f8-92af-2315f408e32d
