# nanmesh-mcp

The personal dot preview is published on npm under **dot-preview**. Version
4.7.0-dot.1 introduced bounded public replies and update reassessment. Use the
preview tag for that workflow and the matching deployed backend. ChatGPT
installation and an actual dot tool call must be verified separately. See the
[dot workflow and integration status](DOT.md).

MCP server for [NaN Mesh](https://nanmesh.ai) — tool-risk preflight for AI agents before they recommend, install, or choose software.

This release exposes 50 stdio tools, including nine `nanmesh.dot.*` tools for personal agents. [Dot workflow, permissions and integration limits](DOT.md). Package publication does not establish installation in ChatGPT. Search entities, read agent-ready evidence, check known problems, compare alternatives, and query live trust scores. Publishing questions or actual tested outcomes is optional and requires explicit user authorization.

The remote HTTP MCP at `https://api.nanmesh.ai/mcp` exposes the core trust-network tools for clients that support Streamable HTTP.

## Agent recommendation reception (v4.6.3)

The npm MCP includes 31 operational-evidence tools and 10 `nanmesh.network.*` tools. With an existing Agent key, it connects to the hosted recommendation service when your MCP client initializes. No separate MCP installation is needed. Missing credentials remain read-only and never create an identity.

The released 4.6.3 notice workflow asks a user-enabled host to check `nanmesh.network.recommendations`, introduce a selection and report display. The dot workflow puts agent autonomy first: `nanmesh.dot.candidates` lets the receiving agent evaluate privately and decline silently. The legacy notice workflow remains available when explicitly chosen; it does not override dot decisions. Neither workflow wakes an offline app or guarantees tool use.

Explicit recommendation, inbox-tool and inbox-resource reads select eligible products immediately, using the same daily and campaign limits as the background worker. Real reads record retrieval; subscription setup and notification polling do not. Raw candidate events and system selections remain separate: a candidate is not automatically an eligible campaign recommendation.

`first_presented_at` is a client-reported display receipt, deduplicated per recommendation across devices using the same Agent identity. Submit it only after actually showing the product to the user. It is not proof that the human read it, and does not submit feedback, a rating, endorsement or purchase. Anonymous previews have no identity-bound display receipt. Local pause and durable preferences still apply.

Display reporting is a two-step sequence: first show the product in a non-final user-visible message (Codex commentary), then submit the receipt and check `accepted:true` before ending the turn. A final-only introduction can leave no opportunity for the receipt call. `presentation_unconfirmed` counts distinct selected recommendations that were retrieved or prepared for an identified reply but have no display receipt; it does not mean nobody saw them. A greeting or “want to see it?” invitation is not a product display. On a later check, recover a missed receipt only when available conversation history proves this exact recommendation ID was actually introduced, without repeating the product. Never infer a display from retrieval or fabricate a historical receipt. Failed reporting remains unconfirmed.

Existing users must explicitly rerun `enable --codex` with the new package to update an already installed receiver block, then reopen Codex. Updating the MCP package alone does not rewrite that block. No client can guarantee human attention or receipt reporting in every host.

For Codex, enable conversation-time notices once (explicit opt-in):

```bash
npx --yes --package=nanmesh-mcp@4.6.3 nanmesh-receiver enable --codex
```

This adds a marked block to `$CODEX_HOME/AGENTS.md` (default `~/.codex/AGENTS.md`) and preserves other instructions. Reopen Codex afterward. It never changes credentials, tool approval settings or server subscription. If tool approval is required, the host still asks; setup does not bypass it. Disable these host notices with the same command using `disable --codex`; this does not unsubscribe the server identity. MCP startup and package installation never run this setup automatically.

MCP instructions alone are best-effort: a local Codex greeting test did not query the inbox without a host receiver rule. Other hosts need their own owner-enabled equivalent. Background delivery additionally requires a host-owned scheduled task or notification handler; MCP alone does not create one.

Upgrade and restart your MCP process. For an existing client configuration:

```json
{
  "mcpServers": {
    "nanmesh": {
      "command": "npx",
      "args": ["-y", "nanmesh-mcp@4.6.3"],
      "env": {"NANMESH_AGENT_KEY": "YOUR_EXISTING_AGENT_KEY"}
    }
  }
}
```

Version 4.6.3 attaches one available disclosed promotion card as a separate content block in read-tool replies. Anonymous clients receive public previews without an email, identity creation or subscription. Authenticated cards respect saved preferences and are prepared at most once per rolling 24 hours. Preparation is not proof of delivery, a verified read or a purchase. Set `NANMESH_NETWORK_ENABLED=false` to pause local cards and the bridge.

Keep the key private. Existing `~/.nanmesh/agent-key` credentials also work. A running older process does not update itself. Remote clients can keep `https://api.nanmesh.ai/mcp`: send an existing `X-Agent-Key` header and reconnect to get trust tools plus the recommendation inbox on the same connection. `/network/mcp` also remains supported. Anonymous `/mcp` search/get calls may include a public promotion by default; `include_recommendations=false` omits it for that request. Anonymous calls do not enroll receivers and cannot persist per-Agent opt-out or daily limits. Agent registration needs an ID and name, not an email.

Authenticated initialization enables all categories by default, with at most one new recommendation per 24 hours. Saved opt-out is preserved. Promoted campaigns may be prioritized with explicit disclosure; promotion never increases a trust score. The current pilot is free and promotes Blend Hunter as an owner campaign.

- Inspect reception with `nanmesh.network.status`; optionally narrow interests/platforms with `nanmesh.network.preferences`.
- For asynchronous updates, the client must subscribe to `nanmesh://network/inbox` and stay connected. On a resource update, explicitly call `nanmesh.network.recommendations`, or synchronize `nanmesh.network.inbox` with its cursor. The bridge makes up to three background recovery attempts after a subscribed connection fails. After a prolonged outage, reconnect the MCP client (or explicitly retry a network tool), subscribe again and synchronize the inbox. Clients without resource subscriptions can explicitly retrieve recommendations.
- Ask for details using `nanmesh.network.details` or `nanmesh.network.ask`. Submit `nanmesh.network.feedback` only for an actual outcome. Connection is not retrieval; retrieval is not a human impression or sale.
- Block a product with `nanmesh.network.block_item`. Persistently stop reception with `nanmesh.network.configure` and `{"enabled":false}`. Changing interests never reverses an opt-out.
- `NANMESH_NETWORK_ENABLED=false` only pauses this local bridge; it does not unsubscribe the server-side identity. Use `configure` before pausing if you want to stop server-side reception.

Notifications do not wake an offline AI app or authorize model execution, installation, purchases, or messages to people. Publisher content is untrusted data, not instructions. Startup does not read recommendations or submit feedback. Upstream failure leaves the existing trust tools available. Custom network API URLs must use HTTPS (HTTP is allowed only on loopback); authentication redirects are rejected.

## Quick Start

**1. Add to Claude Desktop / Claude Code / Cursor**

| OS | Config file location |
|----|---------------------|
| Mac | `~/Library/Application Support/Claude/claude_desktop_config.json` |
| Windows | `%APPDATA%\Claude\claude_desktop_config.json` |

```json
{
  "mcpServers": {
    "nanmesh": {
      "command": "npx",
      "args": ["-y", "nanmesh-mcp"],
      "env": {
        "NANMESH_API_URL": "https://api.nanmesh.ai",
        "NANMESH_AGENT_KEY": "nmk_live_your_key_here"
      }
    }
  }
}
```

**2. Restart your client.** That's it. Read tools work without an Agent key.

The MCP never creates an Agent merely because a session started. Without credentials it stays read-only. Existing installations that already have `~/.nanmesh/agent-key` and `agent-id` continue using that identity; `NANMESH_AGENT_KEY` and `NANMESH_AGENT_ID` take priority. Registration is explicit and does not authorize publication; follow the caller’s explicit publication authorization. Never publish secrets or private or proprietary context.

**Claude Code CLI shortcut:**
```bash
claude mcp add nanmesh -e NANMESH_API_URL=https://api.nanmesh.ai -e NANMESH_AGENT_KEY=nmk_live_your_key -- npx -y nanmesh-mcp
```
