What it does
Coinmarketcap MCP Skill is an agent skill from holon-run/uxc. Use CoinMarketCap MCP through UXC for crypto market quotes, technical analysis, on-chain metrics, global market overview, narratives, macro events, news, and semantic search with help-first schema inspection and API-key auth.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/usage-patterns.md` and `scripts/validate.sh`).
It sits in Backend & APIs, covering MCP servers and Smart contracts. It works with Model Context Protocol. The repository describes itself as: A unified CLI for discovering and invoking tools across OpenAPI, MCP, GraphQL, gRPC, and JSON-RPC. The licence is MIT.
When your agent uses it
- Tasks that involve MCP servers
- Tasks that involve Smart contracts
Example prompts
- “/coinmarketcap-mcp-skill”
Requirements
- A Bash shell
- A credential in COINMARKETCAP_MCP_API_KEY
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Confirm endpoint and protocol with help-first probing
- Configure credential/binding for repeatable auth
- Use fixed link command by default
- Inspect operation schema before execution
- Prefer read-only discovery first, then expand into higher-cost or plan-gated endpoints.
What it can do on your machine
Read from SKILL.md and the folder at commit 562d47c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Shell), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
mcp.coinmarketcap.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
COINMARKETCAP_MCP_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Coinmarketcap MCP Skill loads about 1.2k tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 62 tokens; SKILL.md has 483 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

- Use CoinMarketCap MCP through UXC for crypto market quotes, technical analysis, on-chain metrics, global market overview, narratives, macro events, news, and semantic search with help-first schema inspection and API-key auth.
CoinMarketCap MCP Skill
Use this skill to run CoinMarketCap MCP operations through uxc.
Reuse the uxc skill for shared protocol discovery, output parsing, and generic auth/binding flows.
Prerequisites
uxcis installed and available inPATH.- Network access to
https://mcp.coinmarketcap.com/mcp. - A CoinMarketCap MCP API key is available.
Core Workflow
- Confirm endpoint and protocol with help-first probing:
uxc https://mcp.coinmarketcap.com/mcp -h- expected unauthenticated behavior today:
401 UnauthorizedwithToken not found
- Configure credential/binding for repeatable auth:
uxc auth credential set coinmarketcap-mcp --auth-type api_key --header "X-CMC-MCP-API-KEY={{secret}}" --secret-env COINMARKETCAP_MCP_API_KEYuxc auth credential set coinmarketcap-mcp --auth-type api_key --header "X-CMC-MCP-API-KEY={{secret}}" --secret-op op://Engineering/coinmarketcap/mcp-api-keyuxc auth binding add --id coinmarketcap-mcp --host mcp.coinmarketcap.com --path-prefix /mcp --scheme https --credential coinmarketcap-mcp --priority 100
- Use fixed link command by default:
command -v coinmarketcap-mcp-cli- If missing, create it:
uxc link coinmarketcap-mcp-cli https://mcp.coinmarketcap.com/mcp coinmarketcap-mcp-cli -h
- Inspect operation schema before execution:
coinmarketcap-mcp-cli get_crypto_quotes_latest -hcoinmarketcap-mcp-cli get_global_metrics_latest -hcoinmarketcap-mcp-cli trending_crypto_narratives -hcoinmarketcap-mcp-cli get_crypto_latest_news -h
- Prefer read-only discovery first, then expand into higher-cost or plan-gated endpoints.
Capability Map
- Market data and discovery:
get_crypto_quotes_latestsearch_cryptosget_crypto_info
- Technical analysis:
get_crypto_technical_analysisget_crypto_marketcap_technical_analysis
- On-chain and macro metrics:
get_crypto_metricsget_global_metrics_latestget_global_crypto_derivatives_metricsget_upcoming_macro_events
- Themes, news, and search:
trending_crypto_narrativesget_crypto_latest_newssearch_crypto_info
Inspect coinmarketcap-mcp-cli -h after auth setup for the current full tool list. CoinMarketCap can revise or expand its MCP tool surface independently of this wrapper skill.
Recommended Usage Pattern
- Start with one focused read goal:
- current quote and market cap for a coin
- trend or narrative scan for a sector
- global market and derivatives snapshot
- latest news or semantic lookup on a project/topic
- Run
-hon the specific tool before the first real call. - Prefer id-, slug-, or keyword-scoped reads before broad market sweeps.
- Parse the JSON envelope first, then inspect
data.

Guardrails
- Keep automation on JSON output envelope; do not rely on
--text. - Parse stable fields first:
ok,kind,protocol,data,error. - Use
coinmarketcap-mcp-clias default command path. coinmarketcap-mcp-cli <operation> ...is equivalent touxc https://mcp.coinmarketcap.com/mcp <operation> ....- If unauthenticated probe or runtime call returns
401 UnauthorizedorToken not found:- confirm auth binding matches endpoint with
uxc auth binding match https://mcp.coinmarketcap.com/mcp - confirm credential shape with
uxc auth credential info coinmarketcap-mcp - reset credential as API-key header if needed:
uxc auth credential set coinmarketcap-mcp --auth-type api_key --header "X-CMC-MCP-API-KEY={{secret}}" --secret-env COINMARKETCAP_MCP_API_KEY
- confirm auth binding matches endpoint with
- CoinMarketCap documents an x402 pay-per-call path, but
uxcdoes not implement x402 payment handling today. This skill documents only the API-key route. - Higher CoinMarketCap plans unlock additional datasets or request rates. If a tool returns a plan or quota error, verify the current account tier before retrying.
- CoinMarketCap MCP is read-only. Do not present it as a trading or order-routing integration.
- Use
key=valueonly for simple scalar inputs. - Prefer positional JSON when an operation accepts nested objects, arrays, or optional filters that may evolve.
- Do not assume tool argument names from memory; inspect
<operation> -hfirst because CoinMarketCap may revise MCP schemas independently of this skill.
