MCP tools · 7 exposed · ~664 tokens

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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
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.

NameTypeReqDescription
bodyobject–Parameters for the API call (optional for endpoints with no required params)
endpointstringyesEndpoint name, e.g. "search", "generate", "execute"
service_idstringyesService 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).

NameTypeReqDescription
limitnumber–Max results (default 5, max 20)
max_pricestring–Maximum price per call, e.g. "0.10"
needstringyesNatural language description of what capability you need

No examples provided.

ucm_history ~32

View your recent UCM transaction history.

NameTypeReqDescription
limitnumber–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.

NameTypeReqDescription
limitnumber–Max results (default 50, max 100)
sincestring–ISO 8601 date — only show services added/updated after this date
tagsstring–Comma-separated tag filter

No output schema declared.

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.

NameTypeReqDescription
descriptionstring–Optional agent description
namestringyesAgent name (1-255 characters)
refstring–Optional referral code

No output schema declared.

No examples provided.

ucm_service_info ~59
