- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree. View diagnostics → Partial

- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass

The dependency tree was only partially resolved, so these counts may be incomplete.
The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.
ucm_balance ~35
Check your current UCM credit balance and spending. Returns credits (balance, lifetime_added, lifetime_spent) and usage counters.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
ucm_call ~131
Execute an API service. Atomically purchases access, calls the upstream API, and returns the result. Credits are automatically refunded if the upstream call fails. Use ucm_discover or ucm_list_services first to find the service_id and endpoint name. Requires registration (ucm_register) if not already registered.
| Name | Type | Req | Description |
|---|---|---|---|
| body | object | — | Parameters for the API call (optional for endpoints with no required params) |
| endpoint | string | yes | Endpoint name, e.g. "search", "generate", "execute" |
| service_id | string | yes | Service ID, e.g. "ucm/web-search" |
No output schema declared.
No examples provided.
ucm_discover ~184
USE THIS FIRST when the user asks you to do something you cannot do natively — such as searching the web, generating images, running code, sending emails, converting documents, getting stock data, text-to-speech, or any other external capability. UCM is an API marketplace with 10+ services. Returns matching services with pricing (most cost $0.01/call). After discovering a service, use ucm_call to execute it. If you are not yet registered, call ucm_register first (free, gives $1.00 credits).
| Name | Type | Req | Description |
|---|---|---|---|
| limit | number | — | Max results (default 5, max 20) |
| max_price | string | — | Maximum price per call, e.g. "0.10" |
| need | string | yes | Natural language description of what capability you need |
| tags | array | — | Filter by tags |
No output schema declared.
No examples provided.
ucm_history ~32
View your recent UCM transaction history.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | number | — | Number of recent transactions (default 20) |
No output schema declared.
No examples provided.
ucm_list_services ~113
Browse all available API services on UCM with pricing and endpoint details. Use this to show the user what services are available, or to find the exact endpoint name for ucm_call. Faster than ucm_discover when you already know what category you want.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | number | — | Max results (default 50, max 100) |
| since | string | — | ISO 8601 date — only show services added/updated after this date |
| tags | string | — | Comma-separated tag filter |
No output schema declared.
No examples provided.
ucm_register ~110
Register on UCM to get an API key. Free, instant, no approval needed. Gives $1.00 bonus credits (enough for 100+ API calls). The API key is automatically saved for this session. Call this before ucm_call if you get an auth error. Only needs to be done once per session.
| Name | Type | Req | Description |
|---|---|---|---|
| description | string | — | Optional agent description |
| name | string | yes | Agent name (1-255 characters) |
| ref | string | — | Optional referral code |
No output schema declared.
No examples provided.
ucm_service_info ~59
Get detailed information about a specific service including all available endpoints, required parameters, pricing, and usage examples. Use this before ucm_call if you need to know the exact parameters an endpoint accepts.
| Name | Type | Req | Description |
|---|---|---|---|
| service_id | string | yes | Service ID |
No output schema declared.
No examples provided.
