Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below

From the repository
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.
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
{
"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.
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.
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.

}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
{
"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 \
