Tools: Code Is All You Need
10 months ago
- The author expresses skepticism about the effectiveness of MCP (Machine Control Protocol) in its current form, especially for agentic coding.
- A comparison between GitHub MCP and the gh CLI tool shows the latter is more efficient in using context and achieving results.
- MCP's reliance on inference makes it harder to use than writing code directly, according to the author's experience.
- For automation, code generation is preferred over MCP because it allows for composition, verification, and validation.
- The author shares a personal example of converting reStructuredText to Markdown using an LLM to generate code, which provided more trust and reliability.
- Automating tasks with code is more scalable and reliable than using MCP, as it doesn't depend on inference for each execution.
- The author suggests that MCP might be useful in specific scenarios but generally advocates for bypassing it in favor of code generation.
- Future improvements could involve better abstractions for MCP and code generation, possibly integrating APIs for more efficient inference.
- The potential for LLMs to generate code that non-programmers can understand and use is highlighted as an area for exploration.
