# sdl-mcp vs caveman

*GraphCanon updated Sep 20, 2026*

## Verdict

Pick sdl-mcp if sDL-MCP is a policy-centered tool designed specifically to improve AI-driven coding tasks by managing contexts more efficiently through technologies such as semantic analysis and tree-sitter; pick caveman if caveman reduces token usage by 65% through minimalistic language for coding agents, supporting two sizes and primarily written in Go.

[sdl-mcp](https://github.com/GlitterKill/sdl-mcp) reports 486 GitHub stars, 31 forks, and 0 open issues, last pushed Sep 16, 2026. [caveman](https://docs.caveman.so/docs/quickstart) has 106k stars, 6.2k forks, and 127 open issues, last pushed Sep 18, 2026. Figures are from public GitHub metadata via [sdl-mcp's repository](https://github.com/GlitterKill/sdl-mcp) and [caveman's repository](https://github.com/JuliusBrussee/caveman).

## Decision facts: sdl-mcp

- **Adopt for:** SDL-MCP is a policy-centered tool designed specifically to improve AI-driven coding tasks by managing contexts more efficiently through technologies such as semantic analysis and tree-sitter.

## Decision facts: caveman

- **Pricing:** freemium - The skill, Agent SDK, and initializer are free under MIT license. Hosting Caveman for third parties requires a commercial license.
- **Requirements:** Min 1 GB RAM; Caveman is primarily written in Go and supports two sizes, allowing for flexible deployment.
- **Adopt for:** Caveman reduces token usage by 65% through minimalistic language for coding agents, supporting two sizes and primarily written in Go.
- **License detail:** Caveman operates under a split license: MIT for the skill, Agent SDK, and initializer, and BSL-1.1 for the engine-linked runtime, which converts to Apache-2.0 by 2030 or four years after shipping.

## Choose when

### Choose sdl-mcp if…

- sdl-mcp is primarily TypeScript; caveman is Go.
- Tags unique to sdl-mcp: agent-context, agent-tools, agentic-coding, agentic-engineering.
- Also covers Evaluation & Observability.
- sdl-mcp ships an MCP server manifest.
- When working with sprawling or complex codebases where maintaining context across multiple files is crucial.

### Choose caveman if…

- caveman is primarily Go; sdl-mcp is TypeScript.
- Pricing: The skill, Agent SDK, and initializer are free under MIT license. Hosting Caveman for third parties requires a commercial license..
- Requirements: Min 1 GB RAM; Caveman is primarily written in Go and supports two sizes, allowing for flexible deployment..
- Tags unique to caveman: ai, anthropic, caveman, claude.
- caveman ships Docker support for self-hosted deployment.
- When you need to significantly reduce token usage in coding agents, as Caveman can cut usage by 65% through its simplified language style.

## When NOT to use sdl-mcp

- In environments where TypeScript is not a preferred or supported language.
- For tasks that do not benefit from context management layers, such as small-scale projects with straightforward workflows.
- If your project requires real-time response times for every operation since SDL-MCP's focus on semantic analysis and context budgeting can introduce slight delays.

## When NOT to use caveman

- If your project requires a fully OSI-approved open-source license, as Caveman's engine-linked runtime is BSL-1.1, which is not OSI-approved until a future date.
- When you need a tool that does not involve a trademarked name and logo, as Caveman is trademarked and has specific guidelines for its use.
