Tool catalogue - Locus

The descriptions below are the agent-facing contract — they steer routing. All tools require a valid lsk_… bearer and return content + structuredContent.

Routing at a glance

If the agent needs…	Tool
structured sources for a query	`search`
a concise cited answer	`answer`
an answer accounting for a patient profile	`context`
an antibiotic decision	`atb` (roadmap — not yet available)
a medication datum	`drug` (roadmap — not yet available)

search

Structured, citable retrieval — never a free-form answer.

Argument	Type	Notes
`query`	string	Clinical query (French).
`source_ids`	int[]	Optional source allow-list.
`limit`	int	Max document units (default 10).
`max_chunks_per_unit`	int	Best chunks per unit (default 3).

answer

Concise answer grounded only in the knowledge base, with citations.

Argument	Type	Notes

`source_ids`	int[]	Optional source allow-list.

Roadmap tools

atb and drug are not yet registered on the MCP server. Their intended shape is documented under Roadmap so integrators can plan; they will appear in tools/list only once shipped.
