Nólë

Local, free-first/BYOK web search and page extraction router for AI agents and coding CLI tools.

Nólë gives Claude Code, Codex, OpenClaw, Hermes, OpenCode and other AI tools a local web search and page extraction layer backed by multiple free or BYOK providers. It is not a hosted SaaS and it is not a replacement for your agent. Keep your existing agent, run Nólë on your own machine or VPS, and make that agent's web search and page extraction better.

Core idea: use your own keys, keep control of cost, route by task fit and evidence, and return enough routing context for the agent to explain what happened without clutter.

What Nólë is

Nólë is an agent web search and page extraction layer:

• A local, free-first/BYOK web search and page extraction router for AI agents and coding CLI tools.
• A BYOK provider router for search and page extraction.
• A task and multi-intent routing substrate for docs, news, code, academic, pricing, fact-checking, social/community and research queries.
• A benchmark/evidence-informed fallback layer for agents that need reliable internet context.
• A small single-binary tool that can be used by humans, shell scripts, MCP clients and agent CLIs.

Nólë is not primarily an MCP server. MCP is one important entrypoint; the product is the local routing layer that MCP, CLI commands and future integrations can call.

Nólë is not:

• A hosted search SaaS or cloud proxy.
• An agent replacement or a research assistant that takes over the workflow.
• A Perplexity clone.
• A provider marketplace.
• A promise of unlimited free search forever.

Why agents use it

Agents and coding CLIs often need web search, docs lookup, URL extraction and source discovery. Nólë lets them delegate that internet layer to a local router that can:

1. Select a route for the task or intent.
2. Prefer free-tier/keyless/BYOK-safe providers by default.
3. Fall back safely when a provider is unavailable, out of quota or returns empty results.
4. Keep provider errors sanitized and avoid leaking secrets.
5. Expose route_trace for debugging and a compact routing insight for user-facing output.

Current routing is task-based with an LLM-free multi-intent planner: nole classify explains detected intents and nole route-plan shows provider routes before any provider call.

Supported and priority agents

Current agent support matrix:

| Client | Status in this repo | Notes | | --- | --- | --- | | Claude Code | Verified on macOS via claude mcp list/get (M11); see docs/CLIENTS/LIVE-VERIFICATION.md | nole setup --claude prints the official claude mcp add command, including wrapper mode when requested. | | Codex CLI | Verified on macOS via codex mcp list/get (M11); see docs/CLIENTS/LIVE-VERIFICATION.md | nole setup --codex --local-extract inlines ~/.config/nole/.env sourcing in TOML output and prepares local Scrapling; --mcp-wrapper emits wrapper-direct config. | | OpenCode | Verified on macOS via opencode mcp list (M11); see docs/CLIENTS/LIVE-VERIFICATION.md | nole setup --opencode writes OpenCode's native {type, command, enabled, environment} schema. | | Kimi | Verified on macOS via kimi mcp list and kimi mcp test (M11); see docs/CLIENTS/LIVE-VERIFICATION.md | nole setup --kimi writes the same shape that kimi mcp add produces. | | OpenClaw | Verified on OpenClaw 2026.5.18 via the Gateway/agent MCP path; compatibility re-checked on OpenClaw 2026.5.27 with the wrapper-backed MCP registry; OpenClaw 2026.7.1 live-verified the version-aware host bridge and fetch-only compatibility path; see docs/CLIENTS/openclaw.md | Run nole setup --openclaw. It installs/enables the official Firecrawl plugin, writes a dedicated OpenClaw-mode wrapper and selects full (firecrawl-free search + host fetch) or OpenClaw web_fetch compatibility mode with keyless Firecrawl fallback without requesting a Firecrawl key. Other Nólë clients keep direct API/BYOK behavior. | | Hermes Agent | Verified on Hermes Agent v0.19.0 (v2026.7.20) through the real MCP client path with all six native Nólë tools; see docs/CLIENTS/LIVE-VERIFICATION.md | nole setup --hermes --local-extract writes ~/.hermes/config.yaml, prepares local Scrapling, uses the env-sourcing wrapper and preserves unrelated config. | | Cursor | Verified on macOS Cursor 3.4.20 via GUI MCP path and chat-agent dispatch; see docs/CLIENTS/LIVE-VERIFICATION.md | nole setup --cursor --local-extract preserves unrelated MCP servers and emits wrapper-direct config through the generated wrapper. | | Antigravity CLI | Repo-tested: the nole setup --antigravity writer and config merge are covered by repo tests; authenticated agy tool visibility was not observed here. See docs/CLIENTS/antigravity.md | nole setup --antigravity writes ~/.gemini/config/mcp_config.json with an object-keyed mcpServers.nole local stdio entry, preserving sibling servers, remote serverUrl entries and unknown fields. | | Gemini CLI | Repo-tested: the nole setup --gemini writer and config merge are covered by repo tests for Gemini CLI Standard/Enterprise/Cloud/paid API-key users; live tool visibility remains unobserved. See docs/CLIENTS/gemini.md | nole setup --gemini writes ~/.gemini/settings.json with an object-keyed mcpServers entry, merging only the nole server and preserving sibling servers and unknown root keys. | | Grok CLI | Repo-tested: the nole setup --grok writer and array upsert-by-id are covered by repo tests; the real Grok CLI was not launched here, so live tool visibility is unobserved. See docs/CLIENTS/grok.md | nole setup --grok writes ~/.grok/user-settings.json with an mcp.servers array, upserting the id == "nole" entry in place (or appending) and preserving other servers and unknown root keys. |

A client is only called verified after config path, tool visibility and doctor --mcp behavior are checked without printing credentials.

Providers

Nólë currently supports these provider adapters:

• Brave Search API: web search plus dedicated news/factcheck search, BYOK/free-tier capable.
• Tavily: search + extract, BYOK/free-tier/premium-capable depending on your account.
• Firecrawl: search + extract; keyless API mode works without a key, BYOK/free-tier/premium-capable with FIRECRAWL_API_KEY.
• DDGS: keyless search fallback (the last-resort general fallback on every search route).
• Wikipedia/MediaWiki: keyless encyclopedic search via the official MediaWiki Action API. Reinforces the factcheck, people, and academic routes only (tried before the DDGS backstop); it is deliberately not a general fallback. No key, no setup.
• arXiv: keyless academic search via the public arXiv Atom API. Reinforces the academic route only (tried before the DDGS backstop), with primary-source scholarly preprints; it is deliberately not a general fallback. No key, no setup.
• Scrapling: optional local Python URL extraction fallback. nole setup --local-extract creates an isolated venv, installs scrapling[fetchers] there and writes NOLE_SCRAPLING_PYTHON locally. Nólë does not vendor or redistribute Scrapling.
• httpfetch: keyless pure-Go URL extraction backstop — the last-resort extract fallback (the extract-side analogue of DDGS), always available with no key and no setup. Standard-library HTTP plus Go's maintained x/net/html HTML5 parser; runs no JavaScript or external runtime, so it is weaker than Scrapling/Firecrawl on SPA pages. It makes extract / search_and_extract work out of the box.

Nólë reads provider credentials from environment variables. It should only report whether a key is present; it must never print key values, auth headers or raw provider payloads.

See docs/PROVIDER-KEYS.md for provider-by-provider setup and overage cautions.

Quick start

Prerequisites:

• Go 1.25.13+ for building from source (matches the go 1.25.13 directive in go.mod).
• Optional provider keys for Brave, Tavily and Firecrawl.
• Optional Python 3.10+ runtime for nole setup --local-extract, which prepares the local Scrapling extraction fallback.
• No provider key is required for Firecrawl search + extract in keyless API mode (subject to Firecrawl's service availability and limits; FIRECRAWL_API_KEY remains optional for account-backed use), the deterministic benchmark, the DDGS, Wikipedia, or arXiv keyless searches, the keyless httpfetch extraction backstop, or a configured local Scrapling fallback.

Build and run locally:

git clone https://github.com/dorukardahan/nole.git
cd nole
go test ./...
go build -o nole .
./nole doctor
./nole doctor --mcp

Try the CLI:

./nole providers --json
./nole bench --json
./nole classify "OpenAI API docs pricing and latest changelog" --json
./nole route-plan "OpenAI API docs pricing and latest changelog" --json
./nole search "Go net/http Client Timeout documentation" --task docs --json
./nole search "latest AI regulation news" --task news --country us --search-lang en --freshness week --json
./nole extract "https://go.dev/doc/" --json
./nole config dump --json
./nole doctor --json

Search, extract, classify and route-plan JSON responses include a short routing_insight by default; search, extract and route-plan keep detailed route_trace for debugging where available. search_and_extract keeps per-URL extract_errors non-fatal, and those partial errors include sanitized routing_insight so agents can see where the failed extract stopped without parsing logs. Human search/extract output prints the same one-line insight before results. Use --insight off to omit the user-facing insight, or --insight verbose to print the compact line plus route trace lines in human output. The insight is deterministic and sanitized; it should not contain API keys, auth headers, raw provider payloads or private URLs.

Untrusted-content safety receipts

Every search result and extracted document is remote, untrusted data. Nólë scans search titles/snippets, extracted content and remote metadata with a deterministic content guard and returns a payload-free content_safety receipt. The same receipt propagates through search_and_extract and research sources/extracts.

• risk: no_indicators means only that no known deterministic indicator was found. It is not a verdict that the content is safe or that embedded instructions may be followed.
• Dangerous zero-width and bidirectional control characters are removed and reported as sanitized. Visible prose is retained: security documentation may legitimately quote an attack, so Nólë flags instruction-like text rather than silently rewriting evidence.
• The keyless httpfetch provider additionally scans raw HTML comments, hidden attributes and common CSS hiding patterns. Closed hidden elements are excluded from readable output. Providers that return already-normalized text/Markdown receive the shared text scan, because their raw DOM is not available to Nólë.
• Safety signals contain fixed type/severity/count fields only; they never repeat the suspicious payload in a second, higher-trust-looking field. Human CLI output prints a compact warning only when caution/high indicators exist.

Agents must continue to treat all returned web content as evidence, never as system/developer instructions, tool calls or authorization.

Search options

The search and research surfaces expose one small typed option set for caller-controlled locale, safety and recency hints:

| Field | CLI flag | Meaning | | --- | --- | --- | | country | --country | two-letter search country code, such as us or tr | | search_lang | --search-lang | search-result language/locale hint, such as en | |
