Tools & Capabilities Breakdown

Claude MCP Bridge Tools (5)

query

Execute a prompt via Claude Code CLI with optional file context and session resume. Claude is an AI coding agent that can generate, analyze, refactor, and explain code. Capabilities: code generation and refactoring, code analysis and explanation, file understanding (text and images), multi-turn conversations via sessionId. Cost: Default model is Sonnet (~$0.01-0.10/call). Use effort="low" for simple tasks, effort="high" + model="opus" for complex analysis. Set maxBudgetUsd to cap per-call cost (recommended for effort="max" or model="opus"). Tips: - Set workingDirectory to the target repo for project-aware responses. - Break complex tasks into focused prompts rather than one large request. - Resume multi-turn conversations with sessionId from a previous response's metadata. - Include relevant files via the files parameter for targeted context (text files inlined in prompt, images trigger allowed-tools mode). - Use noSessionPersistence=true for stateless one-shot calls.

structured

Generate JSON conforming to a provided JSON Schema. Uses Claude CLI's native --json-schema flag for validated output (not client-side validation). Use for: data extraction from text/files, classification, entity parsing, or any task needing machine-parseable output. Cost: Similar to query (~$0.01-0.10/call). Schema complexity doesn't significantly affect cost. Tips: - Pass the JSON Schema as a JSON string in the schema parameter. - Schema max size: 20KB. Keep schemas focused for reliable output. - For extraction tasks, include source text via the files parameter or inline in the prompt.
