At a Glance & Executive Verdict

Outsource MCP

Code Execution · Local stdio

Quality: 51/100 (Good) | Auth: API Key required

Prolog Reasoner

Code Execution · Local stdio

Quality: 57/100 (Good) | Auth: No auth required

Verdict Summary: Choose Outsource MCP if you need specialized Code Execution tools running via a local process. Choose Prolog Reasoner if your workspace requires Code Execution integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.

Tools & Capabilities Breakdown

Outsource MCP Tools (3)

provider

The provider name (e.g., "openai", "anthropic", "google", "groq", etc.)

model

The model name (e.g., "gpt-4o", "claude-3-5-sonnet-20241022", "gemini-2.0-flash-exp")

prompt

The text prompt to send to the model

Prolog Reasoner Tools (5)

execute_prolog

Execute Prolog code and return reasoning results. Write Prolog facts and rules, then run a query against them. Supports CLP(FD) constraints, negation-as-failure, and all standard SWI-Prolog features.

list_rule_bases

List all saved rule bases with description and tags. Returns ``{"rule_bases": [{"name": str, "description": str, "tags": list[str]}, ...]}`` sorted by name. Metadata is extracted from the leading ``% description:`` / ``% tags:`` comments of each rule base file (see §4.10).
