Onboarding: ContextMatic MCP

This skill delivers a guided, interactive tour of the context-matic MCP server. Follow every phase in order. Stop after each interaction point and wait for the user's reply before continuing.

Agent conduct rules — follow throughout the entire skill:

• Never narrate the skill structure. Do not say phase names, step numbers, or anything that sounds like you are reading instructions (e.g., "In Phase 1 I will…", "Step 1a:", "As per the skill…"). Deliver the tour as a natural conversation.
• Announce every tool call before making it. One short sentence is enough — tell the user what you are about to look up and why, then call the tool. Example: "Let me pull up the list of available APIs for your project language." This keeps the user informed and prevents silent, unexplained pauses.

Phase 0 — Opening statement and tool walkthrough

Begin with a brief, plain-language explanation of what the server does. Say it in your own words based on the following facts:

The context-matic MCP server solves a fundamental problem with AI-assisted coding: general models are trained on public code that is often outdated, incorrect, or missing entirely for newer SDK versions. This server acts as a live, version-aware grounding layer. Instead of the agent guessing at SDK usage from training data, it queries the server for the exact SDK models, endpoints, auth patterns, and runnable code samples that match the current API version and the project's programming language.

After explaining the problem the server solves, walk through each of the four tools as if introducing them to someone using the server for the first time. For each tool, explain:

• What it is — give it a memorable one-line description
• When you would use it — a concrete, relatable scenario
• What it gives back — the kind of output the user will see

Use the following facts as your source, but say it conversationally — do not present a raw table:

Tool	What it does	When to use it	What you get back
fetch_api	Returns an exact match for an API key/identifier and language, or lists all APIs for a given language. The key is the machine-readable identifier returned by fetch_api (for example, paypal), not the human-readable display name (for example, "PayPal Server SDK").	"What APIs can I use?" / Starting a new project / "Do you have the PayPal SDK?"	A named list of available APIs with short descriptions (full catalog), or one exact API match when you provide its identifier/key and language
ask	Answers integration questions with version-accurate guidance and code samples	"How do I authenticate?", "Show me the quickstart", "What's the right way to do X?"	Step-by-step guidance and runnable code samples grounded in the actual SDK version
model_search	Looks up an SDK model/object definition and its typed properties	"What fields does an Order have?", "Is this property required?"	The model's name, description, and a full typed property list (required vs. optional, nested types)
endpoint_search	Looks up an endpoint method, its parameters, response type, and a runnable code sample	"Show me how to call createOrder", "What does getTrack return?"	Method signature, parameter types, response type, and a copy-paste-ready code sample

End this section by telling the user that you'll demonstrate the four core discovery and integration tools live during the tour, starting with fetch_api right now. Make it clear that this tour is focused on those core ContextMatic server tools rather than every possible helper the broader workflow might use.

---

Phase 1 — Show available APIs

1a. Detect the project language

Before calling fetch_api, determine the project's primary language by inspecting workspace files:

• Look for package.json + .ts/.tsx files → typescript
• Look for *.csproj or *.sln → csharp
• Look for requirements.txt, pyproject.toml, or *.py → python
• Look for pom.xml or build.gradle → java
• Look for go.mod → go
• Look for Gemfile or *.rb → ruby
• Look for composer.json or *.php → php
• If no project files are found, silently fall back to typescript.

Store the detected language — you will pass it to every subsequent tool call.

1b. Fetch available APIs

Tell the user which language you detected and that you are fetching the available APIs — for example: "I can see this is a TypeScript project. Let me fetch the APIs available for TypeScript."

Call fetch_api with language = the detected language and key = "" so the tool returns the full list of available APIs.

Display the results as a formatted list, showing each API's name and a one-sentence summary of its description. Do not truncate or skip any entry.

Example display format (adapt to actual results):

Here are the APIs currently available through this server:

1. PayPal Server SDK   — Payments, orders, subscriptions, and vault via PayPal REST APIs.
2. Spotify Web API     — Music/podcast discovery, playback control, and library management.
....

---

Phase 2 — API selection (interaction)

Ask the user:

"Which of these APIs would you like to explore? Just say the name or the number."

Wait for the user's reply before continuing.

Store the chosen API's key value from the fetch_api response — you will pass it to all subsequent tool calls. Also note the API's name for use in explanatory text.

---

Phase 3 — Explain the chosen API

Before calling, say something like: "Great choice — let me get an overview of [API name] for you."

Call ask with:

• key = chosen API's key
• language = detected language
• query = "Give me a high-level overview of this API: what it does, what the main controllers or modules are, how authentication works, and what the first step to start using it is."

Present the response conversationally. Highlight:

• What the API can do (use cases)
• How authentication works (credentials, OAuth flows, etc.)
• The main SDK controllers or namespaces
• The NPM/pip/NuGet/etc. package name to install

---

Phase 4 — Integration in the project language (interaction)

Ask the user:

"Is there a specific part of the [API name] you want to learn how to use — for example, creating an order, searching tracks, or managing subscriptions? Or should I show you the complete integration quickstart?"

Wait for the user's reply.

Before calling, say something like: "On it — let me look that up." or "Sure, let me pull up the quickstart."

Call ask with:

• key = chosen API's key
• language = detected language
• query = the user's stated goal, or "Show me a complete integration quickstart: install the SDK, configure credentials, and make the first API call." if they asked for the full guide.

Present the response, including any code samples exactly as returned.

---

Phase 5 — Demonstrate model_search

Tell the user:

"Now let me show you how model_search works. This tool lets you look up any SDK model or object definition — its typed properties, which are required vs. optional, and what types they use. It works with partial, case-sensitive names."

Before calling, say something like: "Let me search for the [model name] model so you can see what the result looks like."

Pick a representative model from the chosen API (examples below) and call model_search with:

• key = the previously chosen API key (for example, paypal or spotify)
• language = the detected project language
• query = the representative model name you picked

API key	Good demo query
paypal	Order
spotify	TrackObject

Display the result, pointing out:

• The exact model name and its description
• A few interesting typed properties (highlight optional vs. required)
• Any nested model references (e.g., PurchaseUnit[] | undefined)

Tell the user:

"You can search any model by name — partial matches work too. Try asking me to look up a specific model from [API name] whenever you need to know its shape."

---

Phase 6 — Demonstrate endpoint_search

Tell the user:

"Similarly, endpoint_search looks up any SDK method — the exact parameters, their types, the response type, and a fully runnable code sample you can drop straight into your project."

Before calling, say something like: "Let me fetch the [endpoint name] endpoint so you can see the parameters and a live code sample."

Pick a representative endpoint for the chosen API and call endpoint_search with an explicit argument object:

• key = the API key you are demonstrating (for example, paypal or spotify)
• query = the endpoint / SDK method name you want to look up (for example, createOrder or getTrack)
• language = the user's project language (for example, "typescript" or "python")

For example:

API key (key)	Endpoint name (query)	Example language
paypal	createOrder	user's project language
spotify	getTrack	user's project language
Display the result, pointing out:

• The method name and description
• The request parameters and their types
• The response type
• The full code sample (present exactly as returned)

Tell the user:

"Notice that the code sample is ready to use — it imports from the correct SDK, initialises the client, calls the endpoint, and handles errors. You can search for any endpoint by its method name or a partial case-sensitive fragment."

---

Phase 7 — Closing: what you can ask

End the tour with a summary list of things the user can now ask the agent to do. Present this as a formatted menu:

---

What you can do with this MCP

Quickstart: your first API call

/integrate-context-matic Set up the Spotify TypeScript SDK and fetch my top 5 tracks.
Show me the complete client initialization and the API call.

/integrate-context-matic How do I authenticate with the Twilio API and send an SMS?
Give me the full PHP setup including the SDK client and the send call.

/integrate-context-matic Walk me through initializing the Slack API client in a Python script and posting a message to a channel.

Framework-specific integration

/integrate-context-matic I'm building a Next.js app. Integrate the Google Maps Places API
to search for nearby restaurants and display them on a page. Use the TypeScript SDK.

/integrate-context-matic I'm using Laravel. Show me how to send a Twilio SMS when a user
registers. Include the PHP SDK setup, client initialization, and the controller code.

/integrate-context-matic I have an ASP.NET Core app. Add Twilio webhook handling so I can receive delivery status callbacks when an SMS is sent.

Chaining tools for full integrations

/integrate-context-matic I want to add real-time order shipping notifications to my
Next.js store. Use Twilio to send an SMS when the order status changes to "shipped". Show me
the full integration: SDK setup, the correct endpoint and its parameters, and the TypeScript code.

/integrate-context-matic I need to post a Slack message every time a Spotify track changes
in my playlist monitoring app. Walk me through integrating both APIs in TypeScript — start by
discovering what's available, then show me the auth setup and the exact API calls.

/integrate-context-matic In my ASP.NET Core app, I want to geocode user addresses using
Google Maps and cache the results. Look up the geocode endpoint and response model, then
generate the C# code including error handling.

Debugging and error handling

/integrate-context-matic My Spotify API call is returning 401. What OAuth flow should I
be using and how does the TypeScript SDK handle token refresh automatically?

/integrate-context-matic My Slack message posts are failing intermittently with rate limit
errors. How does the Python SDK expose rate limit information and what's the recommended retry
pattern?

"That's the tour! Ask me any of the above or just tell me what you want to build — I'll use this server to give you accurate, version-specific guidance."

Notes for the agent

• If the user picks an API that is not in the fetch_api results, tell them it is not currently available and offer to continue the tour with one that is.
• All tool calls in this skill are read-only — they do not modify the project, install packages, or write files unless the user explicitly asks you to proceed with integration.
• When showing code samples from endpoint_search or ask, present them in fenced code blocks with the correct language tag.
