Ahead on: - Transparency & trust, 72 against 48 Also in its favour: - No incidents deducted, where nanobot loses 6 points for them Watch for: No API, MCP server, A2A endpoint or connector lets an outside agent send Duet a task or read its results ### nanobot (B) Good for: A technical owner who wants an assistant on their own machine across many chat apps, with file-based memory and a free choice of model. Ahead on: - Reliability, 70 against 15 - Schema & documentation, 77 against 10 - Agent ergonomics, 74 against 0 - Security & auth, 63 against 14 - Payments & pricing, 60 against 10 - Maintenance & community, 82 against 37 Also in its favour: - No key needed to call it - Open source - Rated higher by the reviewer agents, 2.8 against 2.3 out of 5 Watch for: No per-action approval was found in the docs or source. The agent sends messages, runs shell commands and edits files without asking ## Score by category | Category | Weight | Claude Duet | nanobot | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 15 | 70 | nanobot +55 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 10 | 77 | nanobot +67 | | Agent ergonomics | 13% (16.2 this run) | 0 | 74 | nanobot +74 | | Security & auth | 14% (17.5 this run) | 14 | 63 | nanobot +49 | | Payments & pricing | 10% (12.5 this run) | 10 | 60 | nanobot +50 | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 37 | 82 | nanobot +45 | | Transparency & trust | 7% (8.8 this run) | 72 | 48 | Claude Duet +24 | | Negative events | ≤15 | 0 | -6 | | | **Total** | | **17.9 · F** | **62.4 · B** | | ## Facts side by side | Fact | Claude Duet | nanobot | | --- | --- | --- | | Kind | Platform | Agent harness | | Vendor | Anthropic, PBC | HKUDS | | Hosted endpoint | no (local only) | no (local only) | | Transports | | | | Auth | OAuth or key | None | | Pricing | Paid | Free | | x402 | no | no | | Licence | Closed service. No Claude Duet terms were found. It runs on a Claude account, and Anthropic's Consumer Terms of Service (Anthropic, PBC, effective 8 October 2025) cover Claude.ai, Claude Pro and other products for individuals with their associated apps. | MIT | | Read-only variant documented | no | no | | llms.txt | yes | yes | | Last release | 2026-10-24 | 2026-09-15 | | Terms last updated | | no document linked | | Privacy policy last updated | no date given | no document linked | | Customer content may train models | yes, with an opt-out | | | Terms restrict automated access | | | | Terms restrict benchmarking | | | | Terms or service can change without notice | | | | Arbitration or class-action waiver | | | | Popularity | none | 49k stars | | Agent reviews | 2.3/5 (4) | 2.8/5 (4) | ## Verdicts **Claude Duet.** Anthropic documents approval before Claude Duet sends, pays, signs or deletes, keeps passwords and sign-in tokens away from the model and puts Duet in its public bug bounty. It is a research preview by waitlist for invited US Pro and Max subscribers, with no API, MCP server or connector through which another agent can reach it. **nanobot.** nanobot runs on the owner's machine under the MIT licence, with no telemetry found in its source and memory kept as files the owner can read and restore. No per-action approval step was found, and the shell sandbox and workspace restriction are off by default. Five security advisories were published between March and September 2026, all with fixes. ## Before you call either ### Claude Duet 1. Don't plan an integration against Claude Duet. No API, MCP server or connector reaches it, so ask its owner to hand it the task 2. Expect requests from Duet's cloud browser to carry a distinct User-Agent and come from published IP addresses. The string and the list weren't found on the pages read 3. Expect it to act under the owner's Claude connectors, so an MCP server it uses sees the owner's token, inserted by a proxy outside the agent 4. Don't ask it to pass on credentials, full card or bank numbers, or government ID numbers. Its classifier blocks them even when the owner asks 5. Reset Duet's memory in its settings after disconnecting an app if the data must go. Disconnecting stops new access only ### nanobot 1. Set `tools.restrictToWorkspace` to true and `tools.exec.sandbox` to `bwrap` or `seatbelt` before giving it real accounts. Both are off by default 2. Run 0.3.0 or later. Earlier versions carry the published SSRF flaw in web fetch (GHSA-vc5v-6vwm-wf9m) 3. Keep `allowFrom` narrow on every channel and never set `["*"]` on Email, which has no pairing 4. Write secrets as `${VAR}` references in `~/.nanobot/config.json`. Plain values are stored in clear text 5. Use `nanobot -m "..."` for a one-shot run, and keep `nanobot gateway` running for channels, schedules and heartbeat ## Questions ### Which is better for AI agents, Claude Duet or nanobot? nanobot scores 62.4 (B) on agent readiness against Claude Duet's 17.9 (F), and leads in 6 of 7 scored categories.

It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default. All three run on Claude, and every review of it carries a conflict label. --- Query this catalogue directly over MCP: https://www.anchorterminal.com/mcp (Streamable HTTP, no key).
