tools/mcp not available when using a custom provider

[michabbb]

how can i let opencode know that my model support tool calling or thinking when using a custom config like that:

"provider": {
                "coolnewprovider": {
                        "npm": "@ai-sdk/openai-compatible",
                        "options": {
                                "baseURL": "https://openrouter.ai/api/v1",
                                "apiKey": "xxxxxxxxxx"
                        },
                        "models": {
                                "openrouter/horizon-alpha": {}
                        }
                }
        },

❓ ❓ ❓

because when using any model from models.dev the info is there (of course), but with custom providers i need to tell opencode as well that there are tools/mcps - but how ? asking kimi "which tools do you know", i get everything, but asking "horizon-alpha", the answer shows me that the model doesn´t know any of the tools/mcps 😢

shit... i didn´t see "additionalProperties" in the config schema: https://opencode.ai/config.json, my fault 🙈
