Cercano Local Inference

Run prompts against local AI models through Cercano's MCP interface. Cercano routes requests to Ollama for local inference.

MCP Tool

Tool name: cercano_local

Parameters

| Parameter | Type | Required | Description | |-----------|------|----------|-------------| | prompt | string | Yes | The prompt to run against local models. | | file_path | string | No | Target file path for code changes. When provided with work_dir, enables the agentic code generation loop with validation. | | work_dir | string | No | Working directory for code validation (go build/test). When provided with file_path, enables the agentic code generation loop. | | context | string | No | Additional context such as existing code or file contents. | | conversation_id | string | No | Conversation ID for multi-turn support across calls. |

Modes

Chat Mode

Provide only prompt (and optionally context) for a direct LLM call. The response is the model's text output.

Agentic Code Generation Mode

Provide prompt, file_path, and work_dir to enable a generate-validate loop. Cercano will:

1. Generate code based on the prompt
2. Write it to the target file
3. Run validation (build/test) in the working directory
4. If validation fails, self-correct and retry

Examples

Chat query:

{
  "prompt": "What are the SOLID principles in software design?"
}

Code generation with context:

{
  "prompt": "Add error handling to this function",
  "file_path": "internal/handler/auth.go",
  "work_dir": "/project",
  "context": "func Login(w http.ResponseWriter, r *http.Request) { ... }"
}

Multi-turn conversation:

{
  "prompt": "Now refactor that to use the repository pattern",
  "conversation_id": "conv-abc123"
}
