Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.
Please install the MCP server Kitsune MCP for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "kitsune": { "command": "npx", "args": [ "-y", "kitsune-mcp" ] } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) No key is needed. 5) Do what we agreed, then check that the Kitsune MCP tools really show up.This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
The GitHub repo last changed 7 days ago, and the latest version (0.23.0) reached the registry 7 days ago.

🦊 Kitsune MCP Let your agent test the MCP server it's building.
Edit a tool, reload("dev") , call it again. No client restart. ⭐ Saved you a restart? Star it on GitHub so others find it. 📖 Documentation · Hot-reload tutorial · Tools reference
AI agents installing this server (Cline, Claude Code, Cursor, …): follow llms-install.md. No clone or build needed. Add the
uvx kitsune-mcpentry to your MCP settings.
One prompt: Claude finds the bug, fixes it, reloads, checks again. Real recording, 31 s.
Your agent edits an MCP tool, but the client still runs the old process. Someone has to restart it before the agent can test the fix.
With Kitsune, connect, call and reload are tools. The agent runs the whole loop itself:
connect("uv run my-mcp-server", name="dev") # start your server
shapeshift("dev") # its tools appear in the client call("summarize", arguments={"url": "https://example.com"})
reload("dev") # restart on fresh code, remount call("summarize", arguments={"url": "https://example.com"}) # new code, same session
No Docker needed: connect() runs your own server as a plain local process, so the loop stays fast.
It also mounts any of 130,000+ servers from 7 registries mid-session. If Docker is installed, community packages run caged.
Try it: hot-reload tutorial · examples/demo-hot-reload/
Claude Code
claude mcp add -s user kitsune -- uvx kitsune-mcp
Any other client (Claude Desktop, Cursor, Windsurf, Cline, Zed, …):
{
"mcpServers": { "kitsune": { "command": "uvx", "args": ["kitsune-mcp"] } } }
Also on PyPI (pip install kitsune-mcp, then "command": "kitsune-mcp") and npm (npx kitsune-mcp, delegates to uvx).
Requirements: Python 3.12+ · uv · node/npx for npm-based servers · Docker optional: not used for hot-reload, only to cage community servers when installed.
| Loop | What you get | |
|---|---|---|
| MCP REPL | connect → shapeshift → edit → reload → call | Iterate on your own server without restarting the client |
| Long-tail reach | search → shapeshift → call → shapeshift() | Use a server once without adding it to your config forever |
| Try before you trust | confirm=True + Docker cage + version pins | Run community npm/PyPI code contained, not as your user |
search("web scraping")
shapeshift("firecrawl", tools=["scrape_url"]) # mount one tool, not the whole server call("scrape_url", arguments={"url": "https://example.com"}) shapeshift() # drop it, session stays up
search("pdf", registry="glama")
shapeshift("mcp-pdf-tools", confirm=True) # npm/PyPI run in hardened Docker when available call("extract_text", arguments={"path": "report.pdf"}) shapeshift()
auth("BRAVE_API_KEY", "sk-...") # saved to ~/.kitsune/.env, no restart
shapeshift("brave", tools=["brave_web_search"])
Full live walkthrough: docs/demo-realtime.md.
| Use Kitsune when… | Skip it when… |
|---|---|
| You're building an MCP server and want an edit/reload loop | You only use 1–3 trusted servers (configure them natively) |
| A task needs a server that isn't in your config | Every turn hits the same server (keep it always-on) |
| You want to evaluate community MCP code without installing it for good | You want lower token use: modern clients already defer tool schemas, so most configured servers cost little up front |
| Your MCP config is crowded (GATEWAY) | You need a sub-second first call (cold mount takes ~1–15 s) |
shapeshift(server_id) picks a transport (stdio, HTTP+SSE, WebSocket, Docker), connects, reads tools/list, and registers each tool as a native tool with the server's real schema. The client receives notifications/tools/list_changed and sees first-class tools, with no wrapper in between. shapeshift() with no argument removes them and closes the connection.
search() covers the official servers repo, the MCP Registry, Glama, npm, PyPI, GitHub (github:owner/repo) and Smithery (hosted servers, free API key).
Default profile: 9 tools. Standing cost: ~1,774 tokens/turn on clients that load every tool schema up front (measured with python examples/benchmark.py); ~70 tokens/turn on Claude Code with Tool Search, where schemas load only on first use (measured on Claude Code 2.1.319, 2026-11-06).
| Tool | Role |
|---|---|
connect(command, name) | Start a persistent local server, e.g. the one you're developing |
reload(name) | Release, restart on fresh code, remount, in one call |
release(name) | Stop a persistent server |
search(query, registry?) | Search 7 registries |
shapeshift(server_id?, tools=[…]) | Mount a server's tools (all or a subset); no argument drops them |
call(tool_name, arguments) | Call a tool; the server is inferred when mounted |
auth(var_or_server, value?) | Set an env key or run an OAuth 2.1 browser flow |
auto(task, server_hint=) | Search, mount and call in one step |
status() | Current form, connection pool, session stats |
KITSUNE_TOOLS=all (or the kitsune-forge command) adds developer tools: inspect (schemas, credential check, token cost), test (quality score 0–100), bench (p50/p95 latency), compare, prewarm, craft, setup, and more. See docs/tools.md. Companion skills for Claude Code: kitsune-dev, kitsune-improve.
confirm=True. The model can set that flag itself, so real approval belongs in your client's tool-approval UI.connect calls in your client before the agent runs them.--cap-drop ALL, read-only root, memory and PID limits. Credentials are passed by name, never in argv.~/.kitsune/policy.json checks every downstream call against allow/ask/deny rules, path roots and a host allowlist. ask goes to you through MCP elicitation.fetch() blocks private hosts and re-checks every redirect.Don't run it unattended with production admin, billing or security credentials. The full model, including what it does not protect against: docs/safety.md.
.env lookup, tool profiles, sandbox and trust settings, Smithery, GATEWAY, mount patternsIn Japanese folklore the kitsune (狐) is known for what it can *become*: it borrows a form, uses that power, casts it off and returns to itself. That is the product loop.
*I am not Japanese, and I use this name with the highest respect for the mythology and culture it comes from. The parallel felt too precise to ignore.*
