What this skill does

# Add MCP

Transport-agnostic MCP integration guidance. Use this skill when integrating any MCP server regardless of transport.

## When to use

- Connecting to MCP servers using any transport (HTTP, stdio, WebSocket)
- Building skills that need session reuse across multiple MCP operations
- Understanding the session vs one-shot pattern for MCP connections

## Transport routing

| Transport | Skill | Status |
|-----------|-------|--------|
| Streamable HTTP | `add-remote-mcp` | Available |
| stdio | Direct SDK usage | Future |
| WebSocket | Direct SDK usage | Future |

For HTTP endpoints, use `add-remote-mcp`.
That skill starts from the remote URL you are given, which is often a discovery/manifest URL
such as `https://bun.com/docs/mcp`, and then determines whether you can stop at discovery or
need a separate live transport endpoint for session-style calls.

## Session API

The session API maintains a single connection for multiple operations.
See [references/session-template.ts](references/session-template.ts).

`await using` automatically closes the connection when the block exits — no manual cleanup needed.

For remote HTTP servers, only use a session when you have a live transport endpoint.
Manifest/discovery URLs are valid inputs for discovery and listing, but not necessarily for
connection reuse or direct tool invocation.

## One-shot pattern

For single operations, use `mcpConnect` directly.
See [references/one-shot-template.ts](references/one-shot-template.ts).

For remote HTTP discovery/list operations, prefer the higher-level helpers in `plaited/mcp`
such as `mcpDiscover`, `mcpListTools`, `mcpListPrompts`, and `mcpListResources`.

## Framework MCP Library

The framework ships a shared MCP library surface via `plaited/mcp`.

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
