Custom Model Context Protocol (MCP) skills for OpenClaw and AI agents — security-audited, production-ready, with SKILL.md documentation and integration guides. Your agent gains new capabilities in days, not months.
Fixed price · Full source code ownership · No hidden fees
Model Context Protocol (MCP) is the open standard that defines how AI agents discover and use external tools — databases, APIs, file systems, web services, and custom business logic. A "skill" is a packaged MCP tool set that gives your agent new capabilities.
Without well-built skills, agents are limited to their training data. With custom MCP skills, your OpenClaw agent can query your Shopify store, read your database, call any API, and take actions in your real business systems — autonomously.
Production-ready from day one — not a prototype you need to finish yourself.
If a platform has an API, we can build an MCP skill for it. Here are the most requested categories.
Shopify inventory check, order management, customer lookup, product update, discount creation
GA4 report pull, ad platform metrics, custom dashboard data, revenue attribution queries
HubSpot contact management, Klaviyo segment creation, email campaign trigger, lead scoring
Web search with extraction, competitor monitoring, pricing research, market data aggregation
Read/write Google Sheets, query SQL databases, manage Notion pages, process CSV files
Your proprietary API, internal systems, custom workflows — if it has an API, we build the skill
From API docs to production-ready skill — structured and transparent at every step.
We review your target API or system, identify the tool functions your agent needs, and map the authentication method. Skill spec document produced and agreed before coding starts.
Tool function signatures, input/output schemas, error handling paths, and authentication flow designed. Architecture review completed before implementation begins.
Skill implemented in Python or TypeScript — your preference. MCP protocol compliance enforced throughout. Rate limiting, retry logic, and logging built in from the start.
Every skill receives a security audit before delivery — input validation, credential exposure check, permission scope review, and prompt injection resistance testing.
Unit tests for every tool function. Integration tests against live or sandbox API. Edge cases and failure modes explicitly tested. Performance benchmarks measured.
SKILL.md, integration guide, example prompts, and full source code delivered via private GitHub repo. Optional: we publish to the OpenClaw skills marketplace on your behalf.

"The Shopify MCP skill groweik built gave our agent real access to our store data. It now monitors inventory daily and triggers reorders automatically. Zero stockouts in 4 months. The skill paid for itself in the first month."

WhatsApp for QuoteAn MCP skill is a packaged set of tool functions that follow the Model Context Protocol standard. It defines what an AI agent can do — query a database, call an API, read a file — and how to do it safely. Think of it as a plugin that gives your agent a new capability.
Yes — MCP skills connect to APIs or structured interfaces. Most modern platforms (Shopify, HubSpot, Google, AWS, etc.) have APIs. For legacy systems without an API, we can sometimes build a scraping or file-based skill depending on the use case.
Both. We default to Python for most data and API-heavy skills (better library ecosystem). TypeScript for skills integrating with Node.js environments or when you specify it. Your preference is always honoured.
Input validation (preventing injection attacks), credential handling (no hardcoded secrets), permission scope (least-privilege principle), prompt injection resistance (agent can't be manipulated into misusing the skill), and dependency vulnerability scan. A written report is delivered with every skill.
3 or more skills ordered together receive a 15% discount. 5+ skills receive 25% discount. We also offer a skill maintenance retainer for ongoing updates as APIs change — contact us for pricing.
