Enables web search and deep multi-source research for Cerase agents via LiteLLM proxy, with billing attribution per agent.
README
cerase-search MCP
First-party web search for Cerase agents (TOOLS-2). Replaces the
external kiso-search. Routed via cerase-litellm.
Tools
| Tool | LiteLLM alias | Use |
|---|---|---|
search(agent_id, query) |
search (standard) |
everyday "find / look up / latest on" |
deepsearch(agent_id, query) |
deepsearch (advanced) |
deeper multi-source research |
agent_id is bound by the gateway from the calling Agent's identity
(same pattern as cerase-memory's user_id) and is injected into the
LiteLLM request as metadata.cerase_agent_id so RecalcTenantUsage
attributes the spend per-agent.
Billing
A search costs both:
- the token charge at the tool-model multiplier (×3 search / ×15 deepsearch) via the SpendLogs stream, and
- a flat fee
web_search_cr(20 cr) via the gateway'sevent_logmcp_callrow (tool_name∈billable_search_tools).
