MCP API Keys

MCP keys use the nsk_mcp_ prefix and enforce dedicated rate limits and security boundaries separate from standard gateway API keys.

Key Format

Every Neosantara MCP key adheres to the following structure:

nsk_mcp_32characterhexadecimaluuid

Example: nsk_mcp_4f8b9e2a1c3d4e5f6a7b8c9d0e1f2a3b

Supported Authentication Headers

The MCP endpoint (https://api.neosantara.xyz/v1/mcp) accepts keys via either of the following headers:

x-api-key: nsk_mcp_your_key_here

Authorization: Bearer nsk_mcp_your_key_here

Creating Keys via Dashboard

Navigate to the Neosantara Dashboard.
Click Create MCP Key.
Provide a descriptive label (for example: [MCP] Cursor IDE).
Copy and store the key securely; it is displayed only once.

Creating Keys via API

curl -X POST "https://api.neosantara.xyz/v1/mcp/keys" \
  -H "Authorization: Bearer $USER_SESSION_OR_JWT" \
  -H "Content-Type: application/json" \
  -d '{"name": "[MCP] Coding Assistant"}'

Tier Quotas & Rate Limits

The MCP gateway applies rate limiting backed by sliding Redis counters to maintain server stability:

RPM Limit: Request volume per minute per MCP API key.
Daily Requests: Daily request volume quota per MCP API key across a 24-hour window.
Active Key Limit: Each user account may provision up to 5 active MCP keys.
Summary Token Guard: Maximum output tokens allowed when running audit summary tools (mcp_summary_max_tokens).

Account Tier	RPM Limit	Daily Requests	Max Summary Tokens
Free	20 RPM	500 req/day	900 tokens
Basic	40 RPM	1,500 req/day	1,200 tokens
Standard	60 RPM	3,000 req/day	1,600 tokens
Pro	120 RPM	8,000 req/day	2,200 tokens
Enterprise	240 RPM	20,000 req/day	3,200 tokens
Admin	Unlimited	Unlimited	6,400 tokens
