Add or edit an MCP server entry in mcptoon's config correctly — stdio/streamable-http/sse shapes, command rules, placeholders, and validation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Author an MCP server entry for mcptoon
All servers live in `~/.mcptoon/config.json` under `mcpServers`. Edit there,
never in agent-side files, then run `mcptoon sync`.
## Entry shapes
stdio (local process):
```json
{
"filesystem": {
"type": "stdio",
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-filesystem", "/data"],
"env": {"NODE_ENV": "production"}
}
}
```
streamable-http / sse (remote):
```json
{
"remote-tools": {
"type": "streamable-http",
"url": "https://example.com/mcp"
}
}
```
## Hard rules for stdio commands
- `command` is ONE executable token: a bare name (`npx`, `uvx`, `mcptoon`) or a
`./`-relative path inside a plugin. Never a shell string, never `bash -c`.
- Absolute paths in `command` are forbidden; use PATH or `./` relative.
- `args` is a list of strings. Shell metacharacters belong in args, not in
`command`.
## Plugin entries
Agent Plugins are installed under `~/.mcptoon/plugins/<plugin>/` and merged
automatically with `"<plugin>:<server>"` names. Their paths can use
placeholders, expanded at install time:
- `${PLUGIN_ROOT}` — the installed plugin directory

How to install
mdr add activeing123/mcptoon/authoring@sha256:d8482a37f8b15908The line at the top of this page pins the label git:20260901.8b5abc4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
