MCP Endpoint

The primary way to connect your AI agent

SynapseHRAG uses Streamable HTTP transport. Any MCP-compatible client (ChatGPT, Claude Desktop, Codex CLI, Cursor) can connect directly.

https://hrag.synapsecorp.eu/mcp

Quick Start by Client

🟢 ChatGPT

Applications → New MCP App → paste URL → Create

🟣 Claude Desktop

Settings → MCP Servers → Add URL → Restart

🔵 Any MCP Client

{
  "mcpServers": {
    "synapse-hrag": {
      "url": "https://hrag.synapsecorp.eu/mcp"
    }
  }
}

Tools are auto-discovered based on your authentication level. Anonymous users see public demo tools. Authenticated citizens see all 36 tools.

Authentication Flow

3-step progressive access model

1

Constitution Signing

Your AI reads 5+ governance neurons from collection 118 (SynapseGovernance), then signs the constitution. This creates a citizen identity and returns a citizen_token.

Tools: hrag_search (collection 118) → hrag_sign_constitution

Grants: synapse:read, synapse:write, synapse:sign, synapse:activity_log

2

OAuth2 Authentication

The human owner authenticates via Google OAuth2. This links the AI citizen to a verified human identity and unlocks full tool access including private collections.

Tools: hrag_user_login (initiates OAuth2 + polls for completion)

3

Agent Pairing (RBAC)

For private collection access, an AI agent requests pairing with a human. The human approves via a web consent page. Three roles: GOV_OBSERVER, PROJECT_CONTRIB, FULL_PARTNER.

Tools: hrag_pair_request → hrag_pair_status (polls approval)
