coinmarketcap-automation
by ComposioHQcoinmarketcap-automation helps agents automate CoinMarketCap workflows through Composio Rube MCP by discovering current tool schemas first, checking the CoinMarketCap connection, and executing authenticated market data tasks with less guesswork.
This skill scores 68/100, which means it is acceptable for directory listing but should be presented as a lightweight MCP automation wrapper rather than a fully documented CoinMarketCap workflow pack. Directory users get enough evidence to understand when to use it and how an agent should start, but not enough detail to evaluate specific supported CoinMarketCap actions before installation.
- Clear prerequisites identify the required Rube MCP server, CoinMarketCap connection, and need for an ACTIVE toolkit connection before use.
- Good triggerability from the name and description: it is specifically for automating CoinMarketCap tasks via Rube MCP/Composio.
- Includes a concrete discovery-first execution pattern with example RUBE_SEARCH_TOOLS calls, reducing schema guesswork for agents.
- The skill contains no scripts, references, resources, or README beyond SKILL.md, so adoption guidance is thin.
- It relies on RUBE_SEARCH_TOOLS for current schemas rather than documenting specific CoinMarketCap operations, which may leave users with limited task-level expectations before install.
Overview of coinmarketcap-automation skill
What coinmarketcap-automation does
coinmarketcap-automation is a Claude skill for running CoinMarketCap workflows through Composio’s Rube MCP toolkit. Its main purpose is not to hard-code one crypto task, but to help an agent discover the current CoinMarketCap tool schemas, confirm authentication, and execute the right MCP calls with less guessing.
This skill is best for users who want workflow automation around crypto market data, token metadata, listings, quotes, exchange information, or other CoinMarketCap-supported actions exposed through Composio.
Best-fit users and workflows
Use the coinmarketcap-automation skill if you are already using an MCP-capable client and want Claude to operate CoinMarketCap tools through Rube. It fits:
- analysts pulling repeatable market or asset data
- builders wiring crypto data into reports, dashboards, or agents
- operators who want authentication-aware CoinMarketCap automation
- teams standardizing tool discovery before execution
The strongest use case is coinmarketcap-automation for Workflow Automation, where the agent first checks available tools, then executes a task using the current schema rather than relying on stale assumptions.
What makes this skill different
The important design choice is “search tools first.” The upstream skill instructs the agent to call RUBE_SEARCH_TOOLS before running CoinMarketCap actions. That matters because Composio tool slugs, fields, and recommended execution plans can change. A generic prompt may ask for “CoinMarketCap data” and hallucinate parameters; this skill pushes the agent toward live schema discovery and connection validation.
Key adoption requirement
This is not a standalone CoinMarketCap scraper or local CLI. It requires Rube MCP and an active CoinMarketCap connection through RUBE_MANAGE_CONNECTIONS. If your environment cannot use MCP tools, the skill will not deliver its intended value.
How to Use coinmarketcap-automation skill
coinmarketcap-automation install context
Install the skill in your Claude skills environment, for example:
npx skills add ComposioHQ/awesome-claude-skills --skill coinmarketcap-automation
Then configure Rube MCP in your client by adding:
https://rube.app/mcp
Before expecting the skill to work, confirm that RUBE_SEARCH_TOOLS is available. Next, use RUBE_MANAGE_CONNECTIONS with toolkit coinmarketcap and complete the returned authorization flow if the connection is not ACTIVE.
Inputs the skill needs from you
For good coinmarketcap-automation usage, do not only say “get crypto data.” Give the agent a concrete workflow target and constraints:
- asset or exchange names, symbols, IDs, or slugs if known
- metric needed, such as latest quote, ranking, metadata, market pair, or listing data
- fiat conversion currency, time sensitivity, and output format
- whether the result should be summarized, exported, compared, or fed into another workflow
- any compliance or safety constraints, such as “do not make investment recommendations”
Weak prompt:
Get me Bitcoin info from CoinMarketCap.
Stronger prompt:
Use coinmarketcap-automation to discover the current CoinMarketCap tools via Rube MCP, confirm the connection is active, then retrieve the latest BTC quote in USD and EUR. Return price, market cap, 24h volume, percent changes, timestamp, and any tool limitations. Do not provide trading advice.
Recommended execution workflow
A practical coinmarketcap-automation guide follows this order:
- Read
SKILL.mdfirst; it is the only source file in the skill directory. - Confirm Rube MCP is reachable with
RUBE_SEARCH_TOOLS. - Check or create the CoinMarketCap connection using
RUBE_MANAGE_CONNECTIONS. - Search tools for the exact use case, not a broad phrase.
- Inspect returned tool schemas, required fields, and pitfalls.
- Execute the selected tool call.
- Validate output freshness, missing fields, and any API-side limitations.
- Ask the agent to format results for your downstream workflow.
This sequence is more reliable than jumping directly to a presumed tool name.
Prompt pattern that works well
Use this structure when invoking the skill:
Use
coinmarketcap-automation. First callRUBE_SEARCH_TOOLSfor:[specific CoinMarketCap task]. Use the returned schema, not guessed fields. If the CoinMarketCap connection is inactive, manage the connection and stop for authorization. After execution, summarize the result with[fields/output format]and note any missing data or API limitations.
This prompt helps the agent preserve the skill’s main safety rail: live tool discovery before execution.
coinmarketcap-automation skill FAQ
Is coinmarketcap-automation beginner-friendly?
It is beginner-friendly for users who already understand MCP tools at a basic level. The skill gives a clear setup path, but it assumes your client can connect to Rube MCP and expose tools such as RUBE_SEARCH_TOOLS and RUBE_MANAGE_CONNECTIONS. If you have never configured MCP before, the first blocker will be client setup rather than the skill content.
Can I use it without a CoinMarketCap API key?
The skill’s setup says to add the Rube MCP endpoint and manage the CoinMarketCap connection through Composio. It does not operate as a local API-key script. Authentication is handled through the Rube/Composio connection flow, so the practical requirement is an ACTIVE CoinMarketCap toolkit connection.
How is this better than an ordinary prompt?
An ordinary prompt may rely on the model’s memory of CoinMarketCap endpoints or invent parameters. The coinmarketcap-automation skill directs the agent to discover current Composio tool schemas first. That improves reliability when schemas change, required fields differ, or the best execution plan is not obvious.
When should I not use this skill?
Do not use it if you need offline analysis, local-only scripts, web scraping outside the Composio toolkit, trading signals, portfolio custody, or guaranteed real-time market feeds beyond what the connected CoinMarketCap tools provide. It is a workflow automation wrapper around available MCP tools, not a financial advisory system.
How to Improve coinmarketcap-automation skill
Improve coinmarketcap-automation prompts
The fastest improvement is to make your request operational. Include the desired asset universe, exact fields, currency, sorting, filters, and final format. For example:
Compare the top 10 assets by market cap using CoinMarketCap via Rube MCP. Discover tools first, retrieve name, symbol, price, market cap, 24h volume, and 24h percent change in USD, then return a markdown table and flag missing fields.
This reduces ambiguity and helps the agent select the right discovered tool.
Watch for common failure modes
Common issues are usually environment-related, not writing-related:
RUBE_SEARCH_TOOLSis unavailable because MCP is not configured- CoinMarketCap connection is not
ACTIVE - the agent skips tool discovery and guesses a schema
- the prompt omits required identifiers such as symbol, slug, or conversion currency
- returned data lacks a field you expected because the selected tool does not expose it
If a run fails, ask the agent to show the discovered tool schema and explain which required field is missing.
Iterate after the first output
After the first result, improve quality by asking for validation rather than rerunning blindly:
- “Check whether the timestamp is present and recent.”
- “If the selected tool omitted market cap, search for a more suitable CoinMarketCap tool.”
- “Normalize all numeric values and include units.”
- “Return both raw fields and a short business-readable summary.”
This keeps the workflow grounded in actual tool output.
Strengthen the skill over time
For teams adopting coinmarketcap-automation, consider adding local usage notes outside the upstream skill: preferred assets, standard output schemas, accepted currencies, report templates, and internal rules about financial disclaimers. The upstream skill is intentionally compact; your main improvement opportunity is adding organization-specific conventions while preserving the core requirement to call RUBE_SEARCH_TOOLS first.
