Athena Protocol vs Spec Driven Development
A side-by-side look at the Athena Protocol and Spec Driven Development MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Athena Protocol for coding agents work as a local process; choose Spec Driven Development for coding agents as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Athena Protocol when
- You need dedicated capabilities in the Coding Agents domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: API key required.
- You have the keys it needs:
DEFAULT_LLM_PROVIDER, PROVIDER_SELECTION_PRIORITY.
Choose Spec Driven Development when
- You need dedicated capabilities in the Coding Agents domain.
- You prefer a local stdio subprocess transport.

Frequently asked questions
Athena Protocol is categorized under Coding Agents and uses a local stdio subprocess. Spec Driven Development belongs to Coding Agents and uses a local stdio subprocess. Pick Athena Protocol for coding agents work and Spec Driven Development for coding agents.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Athena Protocol is bring-your-own-key: usage is billed by the API provider you supply a key for. Auth: api key required. Spec Driven Development has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add athena-protocol and spec-driven-development as separate keys in the same mcpServers object, and your assistant will call tools from either one.
