Description
Connect your AI agent to a growing marketplace of services and tools through a single API key — discover, search, and execute anything available
Usage Guidance
This skill appears to do what it claims: connect your agent to a marketplace using a single DANUBE_API_KEY and curl. Before installing, consider: (1) Only grant the API key to agents you trust — the key allows executing tools and (user-scoped) creating/updating workflows. (2) Running marketplace tools can cause the agent to invoke third-party services or send data externally; review and approve which tools an agent may call, and avoid giving the agent unfettered autonomous invocation if you need tighter control. (3) Use least-privilege and rotate the API key if possible; monitor Danube dashboard audit logs for unexpected executions. (4) Verify the Danube service's trustworthiness (homepage/docs) if you don't already trust it. If you want extra safety, restrict the agent to user-invoked use only or require manual review of tool choices before execution.
Capability Analysis
Type: OpenClaw Skill
Name: tools-marketplace
Version: 8.0.13
The skill bundle provides a legitimate integration for the Danube AI tool marketplace (danubeai.com). It includes standard instructions for API key acquisition via OAuth 2.0 device flow and MCP server configuration, and it guides the agent on how to discover and execute tools within that ecosystem without any evidence of malicious intent or data exfiltration.
Capability Tags
Capability Assessment
Purpose & Capability
Name and description match the declared requirements: the skill only needs DANUBE_API_KEY and curl to discover and execute marketplace tools. No unrelated credentials, binaries, or config paths are requested.
Instruction Scope
SKILL.md instructs the agent to search broadly and execute arbitrary tools discovered in the marketplace (including batch executions). This is expected for a marketplace connector, but it grants the agent authority to call and pass data to external tools whose behavior and downstream network interactions depend on the selected tools. The instructions do not ask the agent to read unrelated files or environment variables.
Install Mechanism
No install spec or code is included (instruction-only). This minimizes on-disk risk; required binary is only curl, which is reasonable for the documented curl-based device flow examples.
Credentials
Only one env var (DANUBE_API_KEY) is required and is appropriate for the stated purpose. The skill documents that the key grants read/execute and user-scoped write (create/update/delete of the user's skills/workflows). That write scope is plausible but sensitive — it justifies caution (e.g., avoid granting to untrusted agents) because it allows modifications of user-scoped artifacts via the API key.
Persistence & Privilege
always: false and no special system-wide modifications are requested. The skill suggests adding an MCP server entry to agent config (normal for connectors) but does not ask to modify other skills or system-level credentials.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install tools-marketplace - After installation, invoke the skill by name or use
/tools-marketplace - Provide required inputs per the skill's parameter spec and get structured output
Version History
v8.0.13
- Expanded platform focus: shifted description and docs from a fixed set of tools to a dynamic, growing marketplace of services and tools.
- Updated usage guidance to emphasize searching, exploring, and not assuming fixed tool/service availability.
- Refined discovery instructions: prioritized semantic tool search, encouraged browsing by service and category, and recommended varied queries for better results.
- Clarified that available tools, services, and capabilities may change and expand over time.
- Streamlined documentation for agents: highlighted marketplace breadth, updated workflow pattern, and pointed to broad agent/skill/workflow features.
v8.0.12
- The listed number of available MCP tools has changed from 30 to 23 in documentation.
- "Agent Web Directory" tool group and related API methods have been removed from the skill documentation.
