@neuronsearchlab/mcp

MCP (Model Context Protocol) server for NeuronSearchLab. Gives any MCP-compatible AI client (Claude, Codex, Cursor, Windsurf, etc.) direct access to NeuronSearchLab recommendations, product/content search, catalogue operations, analytics, and platform controls.

"Get 5 recommendations for user alice@example.com"
"Check my current plan and show which resources are over their limits"
"Create a new context called Twitter Feed"
"Add a pin rule so Nike items always appear in the top 3"
"Why did item prod-456 rank first for bob?"

Two ways to run it:

• Hosted (recommended, no install): https://console.neuronsearchlab.com/api/mcp — Streamable HTTP with OAuth sign-in or an NSL API key. Listed on the MCP Registry as com.neuronsearchlab/mcp (search neuronsearchlab in the registry API or directory).
• Local stdio via npm: npx -y @neuronsearchlab/mcp in two modes — public (recommendations, events, catalogue via OAuth client credentials) or internal (admin platform via console API key).

Connect to the hosted server (no install)

The hosted endpoint runs a submission-safe customer administration profile. It includes first-class tools for plan and usage visibility, ranking configuration, experiments, training, analytics, catalogue inspection, API-key inventory and revocation, integrations, and event types. Every hosted tool declares its OAuth requirement and requires the authenticated team's admin scope. Credential creation, billing mutations, and the arbitrary platform API fallback remain available only to trusted local/internal clients so secrets, purchases, and unbounded API calls are not exposed in ChatGPT. Keys minted through OAuth consent appear in console → Security and can be revoked there anytime.

claude.ai / Claude Desktop — Settings → Connectors → Add custom connector → paste https://console.neuronsearchlab.com/api/mcp → Connect, then sign in to your NeuronSearchLab console and approve the scopes.

Claude Code

# OAuth (browser sign-in):
claude mcp add --transport http neuronsearchlab https://console.neuronsearchlab.com/api/mcp
# …or with an API key:
claude mcp add --transport http neuronsearchlab https://console.neuronsearchlab.com/api/mcp \
  --header "Authorization: Bearer nsl_your_key"

OpenAI Codex — in ~/.codex/config.toml:

[mcp_servers.neuronsearchlab]
url = "https://console.neuronsearchlab.com/api/mcp"
bearer_token_env_var = "NSL_API_KEY"

Cursor / Windsurf / other Streamable HTTP clients

{
  "mcpServers": {
    "neuronsearchlab": {
      "url": "https://console.neuronsearchlab.com/api/mcp",
      "headers": { "Authorization": "Bearer nsl_your_key" }
    }
  }
}

Tools

API tools

Modes

Public mode

Uses OAuth client credentials and the public API.

Supported:

• recommendations
• events
• catalogue operations

Internal mode

Uses a NeuronSearchLab API key with the admin scope against the console API.

Currently supported:

• account plan and limits: get_account_plan returns the effective plan, resolved limits, current usage, and exact overages
• catalogue search and ranking debug: search_items, explain_ranking
• contexts: list_contexts, create_context, update_context, delete_context, get_context
• pipelines: list_pipelines, create_pipeline, update_pipeline, delete_pipeline, activate_pipeline, deactivate_pipeline, clone_pipeline, get_pipeline
• rules: list_rules, create_rule, update_rule, delete_rule, toggle_rule, enable_rule, disable_rule, get_rule
• segments: list_segments, get_segment, create_segment, update_segment, delete_segment
• experiments: list_experiments, get_experiment, create_experiment, update_experiment, start_experiment, stop_experiment, get_experiment_results, refresh_experiment_results
• training: list_training_jobs, get_training_job, create_training_job, cancel_training_job
• analytics: get_ranking_metrics, get_user_analytics, get_item_analytics, compare_items, top_items
• event types: list_event_types, create_event_type, update_event_type, delete_event_type
• credentials and integrations: list_api_keys, revoke_api_key, list_integrations (create_api_key is local/internal only because it returns credential material)
• fallback UI coverage for trusted local/internal clients only: list_platform_routes, call_platform_api

Quickstart (local stdio)

1. Get credentials

Generate SDK Credentials (OAuth 2.0 client ID + secret) from the NeuronSearchLab console.

2. Add to Claude Desktop

Public mode (recommendations, events, catalogue):

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "neuronsearchlab": {
      "command": "npx",
      "args": ["-y", "@neuronsearchlab/mcp"],
      "env": {
        "NSL_CLIENT_ID": "your-client-id",
        "NSL_CLIENT_SECRET": "your-client-secret"
      }
    }
  }
}

Internal mode (admin platform — contexts, pipelines, rules, analytics, etc.):

{
  "mcpServers": {
    "neuronsearchlab": {
      "command": "npx",
      "args": ["-y", "@neuronsearchlab/mcp"],
      "env": {
        "NSL_PLATFORM_MODE": "internal",
        "NSL_API_KEY": "your-admin-api-key"
      }
    }
  }
}

Restart Claude Desktop. You'll see a 🔌 neuronsearchlab indicator in the toolbar when it's connected.

Try it: recommendation-ops demo

Once connected, run this named demo path before wiring the server into a larger workflow. It proves that an AI client can operate the recommender as an investigation surface rather than just call a recommendation endpoint.

1. List contexts so the assistant confirms the exact surface it is about to inspect.
2. Fetch recommendations for a known test user and context.
3. Search the catalogue for a concrete product/content phrase and compare the returned item IDs with the recommendation set.
4. Explain one ranked item using the request_id from the recommendation or search response when available.
5. Optional, sandbox only: draft or toggle a rule after the explanation shows the expected leak. Keep production contexts read-only unless the operator explicitly approves a write.

Use the NeuronSearchLab MCP server in read-only mode first.
List my recommendation contexts and choose the homepage-feed context.
Get 10 recommendations for user demo-user@example.com using context homepage-feed.
Search the catalogue for waterproof jackets and show the top 5 item ids.
Explain why the first recommended item ranked first, using the request_id from the recommendation response if available.
If you see a relevance leak, draft the smallest rule that would fix it, but do not create or toggle the rule yet.

Internal/admin mode can also inspect operational state before making changes:

List ranking rules for the homepage-feed context.
Show the latest ranking metrics for that context.
Compare item jacket-123 with item jacket-456 and explain which rule or signal separates them.

Next steps after the smoke test:

• create a scoped API key for the client or MCP server
• connect one real recommendation context, such as homepage-feed
• add request attribution to click/view events before judging ranking quality

3. Cursor / other MCP clients

Follow your client's MCP server guide. The command is:

npx @neuronsearchlab/mcp

Set NSL_CLIENT_ID + NSL_CLIENT_SECRET for public mode, or NSL_PLATFORM_MODE=internal + NSL_API_KEY for internal mode.
