Systemores Behavior Profiler API & MCP Server

Stateless Streamable HTTP • MCP 2026 • OpenAPI 3.1.0

Systemores Behavior Profiler API & MCP 2026 Server

Query 21-dimension Murray Needs-Press signatures, Big Five OCEAN percentiles, and deterministic synergy/friction comparisons across 25,040+ public figures, brands, and global cities with zero authentication friction for read-only discovery.

MCP Endpoint

https://profile.systemores.com/api/mcp

1. Connect via MCP Client

Add the read-only Streamable HTTP server to Claude Desktop, Cursor, Antigravity, or any MCP 2026 compatible host. Also reachable via the short alias /mcp.

{
  "mcpServers": {
    "systemores-profiler": {
      "type": "streamable-http",
      "url": "https://profile.systemores.com/api/mcp"
    }
  }
}

2. Call MCP Tool over HTTP

Every tool declares readOnlyHint: true, strict integer schemas, structured JSON outputs (structuredContent), and W3C traceparent correlation.

curl -sS -X POST https://profile.systemores.com/api/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "get_behavioral_signature",
      "arguments": { "slug": "satya-nadella" }
    }
  }'

Registered MCP 2026 Tools

All tools operate in stateless JSON-RPC 2.0 mode with Redis-backed sliding-window rate limiting (30 req/min per IP).

readOnlyHint: true

search_behavioral_profiles

Search Public Behavioral Profiles

Full-text and archetype-filtered search over indexed public figures, entities, and cities.

Params: query (required), category?, archetype?, limit? (1-25), page? (1-100)

get_behavioral_signature

Get 21D Behavioral Signature

Returns the 21-dimension Murray Needs-Press vector, Big Five OCEAN, MBTI/DISC mappings, and playbook.

Params: slug (required, ^[a-z0-9-]+$)

compare_behavioral_signatures

Compare Two Behavioral Signatures

Computes deterministic cosine similarity, 0-100 compatibility index, alignment traits, and friction vectors.

Params: slug_a (required), slug_b (required)

REST API v1 & Markdown Content Negotiation

Prefer direct REST calls or lightweight Markdown briefings? Use our versioned JSON endpoints (60 req/min per IP) or pass Accept: text/markdown to any profile URL.

# Search profiles
curl -sS "https://profile.systemores.com/api/v1/profiles?q=satya&category=individuals&limit=5"

# Retrieve full 21D + Big Five signature
curl -sS "https://profile.systemores.com/api/v1/profiles/satya-nadella"

# Compare two profiles deterministically
curl -sS "https://profile.systemores.com/api/v1/compare/satya-nadella/microsoft"

# Request agent-friendly Markdown directly from any profile URL
curl -sS -H "Accept: text/markdown" "https://profile.systemores.com/satya-nadella"

Rate Limits, RFC Headers & Typed JSON Errors

REST endpoints (/api/v1/*) permit 60 requests per 60 seconds per IP and the MCP endpoint (/api/mcp) permits 30 requests per 60 seconds. Every response includes standard RFC RateLimit-Limit, RateLimit-Remaining, RateLimit-Reset, and RateLimit-Policy headers, plus Retry-After on HTTP 429. All 4xx and 5xx errors return a typed JSON Problem Details payload with code, message, and resolution.

API Versioning, Deprecation & Sunset Policy

Major versions live in the URL path (/api/v1/*) and every response declares X-API-Version: 1.0.0. Before retiring any versioned surface, Systemores provides at least a 180-day sunset window with standard RFC 9745 Deprecation and RFC 8594 Sunset headers.
