MCP

Neither MCP tools

Free beta stdio MCP server for coding agents. Every memory response exposes provenance — occurred_at, bc_id, source_id, participants, and thread_id when available — not anonymous text chunks.

Timeline and push tools accept metadata so future event-ledger fields map cleanly. memory_for_file returns labeled Decision, Rejected, Constraint, and Citation prose — not titles-only UUID lines.

Cursor / Claude Desktop config

Add to your MCP settings JSON:

{
  "mcpServers": {
    "neither": {
      "command": "npx",
      "args": ["-y", "@neitherai/mcp-server@latest"],
      "env": {
        "NEITHER_API_KEY": "sk_ctx_…",
        "NEITHER_API_BASE": "https://api.neither.online"
      }
    }
  }
}

Call Neither at delivery forks and planning writes — when choosing between approaches or aligning strategy — not on every file open or for passive archaeology.

NEITHER_API_KEY is required (sk_ctx_* from /developers/quickstart). NEITHER_API_BASE defaults to https://api.neither.online when omitted.

Free beta — no waitlist required. Create a workspace key on the developer quickstart and paste it above.
