  -d '{"jsonrpc": "2.0", "method": "tools/call", "id": 1, "params": {"name": "get_cat_breed", "arguments": {"breed_id": "'persian'"}}}'

import httpx

resp = httpx.post(
    "https://context.gnist.ai/mcp/cat-breeds/",

    json={'id': 1,
 'jsonrpc': '2.0',
 'method': 'tools/call',
 'params': {'arguments': {'breed_id': "'persian'"}, 'name': 'get_cat_breed'}},
)
print(resp.json())

`list_cat_breeds`

List cat breeds with optional filters. Filters can be combined (AND logic). Returns all breeds if no filters are specified.

Parameter	Type	Required	Description
`origin`	any	optional	Filter by country of origin (e.g. 'United States', 'Thailand'). Omit for all origins.
`size`	any	optional	Filter by size: Small, Medium, or Large. Omit for all sizes.
`coat_length`	any	optional	Filter by coat length: Short, Medium, Long, or Hairless. Omit for all types.

 'method': 'tools/call',
 'params': {'arguments': {'origin': "'United"}, 'name': 'list_cat_breeds'}},
)
print(resp.json())

`search_cat_breeds`

Search for cat breeds by keyword. Searches across breed name, origin, temperament traits, coat length, and description. Case-insensitive.

Parameter	Type	Required	Description
`query`	string	required	Search keyword — matches breed name, origin, temperament, coat type, or description.

import httpx

resp = httpx.post(
    "https://context.gnist.ai/mcp/cat-breeds/",

print(resp.json())

Common Patterns

Search then retrieve
Use list_cat_breeds to find items, then get_cat_breed to get full details. This two-step pattern is common for exploring data before drilling down.

Pagination
Several tools support limit, offset, or page parameters. Start with small limits during development, then increase for production queries.
