鵲 - Bridge Claude Desktop to Streamable HTTP MCP servers via mcp-proxy

[!IMPORTANT] As of now, Claude Desktop officially supports custom connectors for remote MCP servers. I recommend considering that option first. While mcp-proxy is a great and easy-to-use tool, the scenarios where it is still necessary are likely limited now that official support exists. Additionally, custom connectors work not only with Claude Desktop but also with the web version of Claude, once configured.

Install

uv tool install cdcasasagi

Usage

The add and import commands default to preview mode (no files are modified). Pass --write to apply changes. For full option details, run cdcasasagi <command> --help.

add

Add a single MCP server entry:

cdcasasagi add https://developers.openai.com/mcp

This shows a unified diff of the proposed change. Pass --write to apply:

cdcasasagi add https://developers.openai.com/mcp --write

A server name is automatically derived from the URL hostname (e.g. developers for the URL above). Use --name to specify a custom name:

cdcasasagi add https://developers.openai.com/mcp --name openai-developer-docs --write

The written entry looks like this:

{
  "mcpServers": {
    "openai-developer-docs": {
      "command": "/Users/you/.local/bin/mcp-proxy",
      "args": [
        "--transport",
        "streamablehttp",
        "https://developers.openai.com/mcp"
      ]
    }
  }
}

import

Add multiple entries at once from a JSONL file:

cdcasasagi import servers.jsonl

Each line is a JSON object with a required url key and optional name / transport keys:

{"url": "https://developers.openai.com/mcp", "name": "openai-developer-docs"}
{"url": "https://example.com/mcp"}

Stdin is also supported — pipe a file, or pass - and paste the JSONL interactively:

cat servers.jsonl | cdcasasagi import -

cdcasasagi import - --write
# Paste JSONL, then press Enter on a blank line to finish
# (Ctrl+D / Ctrl+Z also works)

validate-import

Validate a JSONL file's schema without importing. This command never writes any files.

cdcasasagi validate-import servers.jsonl

Paste JSONL from stdin instead of preparing a file:

cdcasasagi validate-import -
# Paste JSONL, then press Enter on a blank line to finish
# (Ctrl+D / Ctrl+Z also works)

Once the JSONL validates, feed the same content to import - --write to apply it.

revert

Restore the config from the .bak backup created by the last --write:

cdcasasagi revert

version

cdcasasagi version
