This PR adds a new Tools api and adds two tool runtime providers: brave and MCP. Test plan: ``` curl -X POST 'http://localhost:5000/alpha/toolgroups/register' \ -H 'Content-Type: application/json' \ -d '{ "tool_group_id": "simple_tool", "tool_group": { "type": "model_context_protocol", "endpoint": {"uri": "http://localhost:56000/sse"} }, "provider_id": "model-context-protocol" }' curl -X POST 'http://localhost:5000/alpha/toolgroups/register' \ -H 'Content-Type: application/json' \ -d '{ "tool_group_id": "search", "provider_id": "brave-search", "tool_group": { "type": "user_defined", "tools": [ { "name": "brave_search", "description": "A web search tool", "parameters": [ { "name": "query", "parameter_type": "string", "description": "The query to search" } ], "metadata": {}, "tool_prompt_format": "json" } ] } }' curl -X GET http://localhost:5000/alpha/tools/list | jq . % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 662 100 662 0 0 333k 0 --:--:-- --:--:-- --:--:-- 646k [ { "identifier": "brave_search", "provider_resource_id": "brave_search", "provider_id": "brave-search", "type": "tool", "tool_group": "search", "description": "A web search tool", "parameters": [ { "name": "query", "parameter_type": "string", "description": "The query to search" } ], "metadata": {}, "tool_prompt_format": "json" }, { "identifier": "fetch", "provider_resource_id": "fetch", "provider_id": "model-context-protocol", "type": "tool", "tool_group": "simple_tool", "description": "Fetches a website and returns its content", "parameters": [ { "name": "url", "parameter_type": "string", "description": "URL to fetch" } ], "metadata": { "endpoint": "http://localhost:56000/sse" }, "tool_prompt_format": "json" } ] curl -X POST 'http://localhost:5000/alpha/tool-runtime/invoke' \ -H 'Content-Type: application/json' \ -d '{ "tool_name": "fetch", "args": { "url": "http://google.com/" } }' curl -X POST 'http://localhost:5000/alpha/tool-runtime/invoke' \ -H 'Content-Type: application/json' -H 'X-LlamaStack-ProviderData: {"api_key": "<KEY>"}' \ -d '{ "tool_name": "brave_search", "args": { "query": "who is meta ceo" } }' ```
