LemonCrow — All Agent CLI Integrations

Install LemonCrow into every supported coding agent host in one command:

make install    # install into all CLIs found on PATH
make verify     # verify code, runtime, and installed hosts

Installers write user/global host config by default. To install project-local artifacts for a specific workspace, pass --workspace DIR to the script:

bash scripts/install_hosts.sh --workspace /path/to/workspace

Supported Hosts

Host	Support Level	Advanced installer
Claude Code	Full plugin (skills, commands, hooks, MCP)	scripts/install_claude.sh
Codex CLI	Native MCP registration + AGENTS + plugin bundle	scripts/install_codex.sh
Cursor	MCP server config + rules	scripts/install_cursor.sh
opencode	MCP + workspace agent profile	scripts/install_opencode.sh
Copilot	MCP + instructions + agent + tasks	scripts/install_copilot.sh
Hermes Agent	MCP server config + toolset	scripts/install_hermes.sh
Antigravity	MCP + generated AGENTS surface	scripts/install_antigravity.sh

Quickstart (install everything at once)

# 1. Make sure you're in the lemoncrow/ directory
cd lemoncrow

# 2. Install dependencies
uv sync --all-extras

# 3. Install into all available agent CLIs
make install

# 4. Verify
make verify

Hosts whose CLIs are not on PATH are skipped gracefully — this is expected in CI.

Behavior Contract

All install scripts:

• Are idempotent — safe to run multiple times
• Back up existing files before any write (.lemoncrow-backup.TIMESTAMP)
• Skip gracefully if the host CLI is not on PATH (exit 0)
• Support --dry-run (print actions, write nothing)
• Support --print-only (print manual steps for offline/audited environments)
• Support --strict (exit nonzero if CLI absent — useful for CI gates)
• Support --workspace PATH to write project-local artifacts instead of user/global config

Integrations Layout

Detailed documentation and example configs for each host live in:

lemoncrow/integrations/
├── claude/          # Full plugin config
├── codex/           # Codex plugin template + marketplace docs
├── cursor/          # Cursor MCP config + rules
├── opencode/        # opencode.json example
├── copilot/         # .vscode/mcp.json + copilot-instructions
├── copilot-cli/     # Copilot CLI config
└── antigravity/     # Antigravity MCP template + host guidance

Hermes has no directory here — its installer writes ~/.hermes/config.yaml directly.

Host install entrypoints are under scripts/install_<host>.sh.

---

MCP Transport

All hosts ultimately invoke the same LemonCrow MCP server, but packaged hosts now carry their own host-specific wrapper surfaces:

lc mcp

That repo wrapper remains the canonical MCP entrypoint for direct MCP-only installs. Codex packages that same runtime behavior behind a plugin-local wrapper, while Antigravity uses workspace or user MCP configuration plus a generated host surface.

Common MCP Surfaces

All hosts ultimately use the same LemonCrow stdio MCP server.

• trace is the consistently active observable recording surface.
• With LEMONCROW_DEV_MODE=1, hosts can actively use context, route, rescue, verify, memory, read, edit, sql, search, compact, bash, and the lemoncrow_code_* helpers.
• Packaged hosts may add wrapper tasks, skills, or commands on top of that shared MCP surface.

Uninstalling

Use lc uninstall to remove the main LemonCrow install and managed host integrations. Host-specific uninstall scripts remain available when you only want to remove one host surface.
