# Canonical catalog of well-known MCP server presets (harn#2650).
#
# This is the harn-owned source of truth for one-click MCP servers, rendered
# identically by every client (the burin-code TUI and the macOS GUI). It is
# **data, not code** (harn#3348): edit it here to change the shipped defaults,
# or override/extend it at runtime without a recompile via
# `~/.config/harn/mcp_presets.toml` (or the `HARN_MCP_PRESETS_CONFIG` env var).
# Runtime overlays merge last-writer-wins by `id`, then append new presets.
#
# Field names are snake_case here; the stable JSON contract serializes them as
# camelCase (see `mcp_presets.rs`). Transport-specific fields: `command`/`args`
# populate a stdio spec, `url` populates an HTTP spec. Omit what does not apply.
