Marmot is an open-source (MIT) CLI for AI, web search, scraping, and enrichment data. It is built for agents, agent skills, and standalone scripts that need reliable access to external providers. Marmot composes naturally with shell pipes and supports presets, caching, retries, sessions, and structured output.
Claude Code, Codex, OpenCode, OpenClaw, Hermes, and similar agents are strongest when their context stays focused. But agent workflows still need web search, scraping, enrichment data, retries, caching, and small helper prompts.
Marmot gives agents one shell-native command shape for external calls. Instead of teaching every agent a dozen provider CLIs, or spinning up subagents for routine lookups, you give them one interface for AI providers, search APIs, scraping tools, and enrichment services. Agents with the Marmot skill can learn the pattern once, pipe results through shell workflows, and bring back only the output the main agent needs.
It also lets each task use the right model. A quick classification, a local or private prompt, and a long synthesis do not need to run through the same model your main agent or subagent is configured with. Marmot lets you choose faster, cheaper, local, or stronger models at the command level.
- 🔌 One shape, many providers. Same flags across OpenRouter, Anthropic, OpenAI, Vercel AI Gateway, Cloudflare Workers AI, and Ollama for AI; Brave, Exa, Firecrawl, Parallel, Tavily for web; Apollo, Hunter, PDL, Tomba, Bouncer, Datagma, ZeroBounce, Kickbox for data.
- 🤖 Agent-friendly. Default plain-text output for piping;
--jsonenvelope for structured parsing. - 🧰 Composable. Chain verbs through pipes:
marmot search ... | marmot "summarize". - 🪵 Predictable. Stable exit codes, stderr/stdout separation, deterministic JSON envelope shapes.
- 💾 Optional response cache. Disabled by default; enable per-provider for repeat calls.
- 🪟 Sessions and presets. Persist chat history; save flag bundles for reuse.
npm install -g @marmot-sh/cli
# or the shorter unscoped alias (same binary):
npm install -g marmot-shThis installs the marmot binary globally. Verify with marmot --version.
Set at least one provider API key, then run the wizard:
export OPENROUTER_API_KEY=sk-or-v1-...
marmot setupmarmot setup is an interactive wizard that walks you through:
- Picking default providers and models for each verb.
- Enabling/disabling providers, custom env var names, and the response cache.
- Installing the agent skill (for Claude Code, OpenCode, Codex, and similar harnesses).
Re-run marmot setup any time to change settings, or use marmot config set/show/unset for individual changes.
The default verb is text generation, so a bare marmot call goes straight to a model:
marmot "tell me a joke"Search the web, then summarize:
marmot search "news about apple" \
| marmot "summarize"Get five bullets out of any topic:
marmot search "openrouter pricing 2026" \
| marmot "give me 5 bullet highlights"Compose with other shell tools. For example, pull a day of mail with gog and hand it to a fast model:
gog gmail search "newer_than:1d" \
| marmot "summarize today's email"Pipe stdin straight into the prompt:
git diff | marmot --stream "commit message under 60 chars"Enrich a person from an email:
marmot enrich --type person --email tcook@apple.com| Category | Command | Purpose |

Marmot is built around shell pipes. stdout carries results, stderr carries spinners and status, so chains stay clean.
# search → summarize
marmot search "openrouter pricing" | marmot "summarize for a slack message"
# scrape → translate
marmot scrape https://example.com/article --format text | marmot "translate to French"
# git diff → commit message → clipboard
git diff | marmot --stream "commit message under 60 chars" | pbcopyThe --json flag forces a structured envelope for verbs that default to plain text:
marmot --json "give me 3 ideas" | jq -r '.text'Save flag bundles with names. Reuse with --preset or the @ sigil.
marmot preset create haiku --mode text \
--provider anthropic --model claude-haiku-4-5-20251001 \
--system "Reply only with a 5-7-5 haiku, no prose."
marmot @haiku "the sea at dusk"Other modes: image, speech, transcription. Same pattern works for image styles, voice + speed bundles, and transcription language defaults. Override any preset flag at the call site.
Persist chat history across marmot invocations.
marmot session create research --mode chat
marmot session use research
marmot "What are the leading vector databases in 2026?"
marmot "Of those, which support hybrid search?"
marmot "Pick one and write a setup script"
marmot session show research # totals, message count, window usage
marmot session export research # export as jsonl or markdownStateless mode (logs only, no history threading) is also available with --mode stateless.
Marmot ships an agent skill for Claude Code, OpenCode, Codex, and similar harnesses. The skill teaches the agent Marmot's verb shape, output formats, and provider matrix so it can compose calls without you writing prompts.
Run marmot setup and choose "Install or update agent skill", or install via the skills CLI:
npx skills add https://github.com/marmot-sh/marmot --skill marmotClaude Code users can also install via the native plugin marketplace:
/plugin marketplace add marmot-sh/marmot
/plugin install marmot@marmotEither path installs to the canonical ~/.agents/skills/marmot/ and creates per-harness symlinks (~/.claude/skills/marmot, ~/.opencode/skills/marmot, ~/.codex/skills/marmot).
# Remove the CLI
npm uninstall -g marmot-sh # or @marmot-sh/cli
# Optional — also remove config, presets, pipelines, cache, sessions, usage:
rm -rf "${MARMOT_HOME:-$HOME/.marmot}"
# Optional — also remove the agent skill (if installed):
rm -rf ~/.agents/skills/marmot
rm -f ~/.claude/skills/marmot ~/.opencode/skills/marmot ~/.codex/skills/marmotFull docs at marmot.sh/docs:
- Quickstart — set a key, run a prompt.
- Providers — capability matrix and env vars.
- Command reference — all verbs.
Contributions are welcome. See CONTRIBUTING.md for details.
Marmot leans on excellent open-source work. Vercel's AI SDK drives model calls across every modality, with @ai-sdk/openai, @ai-sdk/anthropic, and the OpenRouter provider plugged in. Commander shapes the CLI surface and Clack powers the interactive setup wizard.
