Algenta MCP Server

Model Context Protocol server for the Algenta API. It gives MCP-compatible agents access to governed data discovery, exact queries, decisions, simulations, runtime utilities, and account operations through the same public API contract used by the Algenta SDKs.

Full reference: docs.algenta.ai/sdk/mcp

Install

pipx install algenta-mcp

pip install algenta-mcp is also supported. The package includes its MCP transport dependencies; users do not install or manage a separate protocol package.

Configure

export ALGENTA_API_KEY="<YOUR_ALGENTA_API_KEY>"
export ALGENTA_BASE_URL="https://api.algenta.ai"

Use your deployment URL for self-hosted Algenta. Private deployment profiles fail closed rather than silently sending traffic to Algenta Cloud.

Cursor and Claude Desktop

algenta-mcp uses stdio by default. Add this server to Cursor's ~/.cursor/mcp.json or Claude Desktop's MCP configuration:

{
  "mcpServers": {
    "algenta": {
      "command": "algenta-mcp",
      "env": {
        "ALGENTA_API_KEY": "<YOUR_ALGENTA_API_KEY>",
        "ALGENTA_BASE_URL": "https://api.algenta.ai"
      }
    }
  }
}

Restart the client after changing its MCP configuration.

Codex

Add the stdio server to ~/.codex/config.toml:

[mcp_servers.algenta]
command = "algenta-mcp"

[mcp_servers.algenta.env]
ALGENTA_API_KEY = "<YOUR_ALGENTA_API_KEY>"
ALGENTA_BASE_URL = "https://api.algenta.ai"

Keep credentials in user-level configuration or environment variables, not in a repository.

Streamable HTTP

Start the remote transport:

algenta-mcp --mode http --port 8001

The standalone server binds to 127.0.0.1 by default. Set ALGENTA_MCP_HOST=0.0.0.0 only when an authenticated container ingress or gateway must expose it to another host.

Connect modern clients to:

http://localhost:8001/mcp

The endpoint uses stateless Streamable HTTP. It dual-serves both protocol eras from the same endpoint: a legacy initialize handshake negotiates 2025-11-25, and a modern per-request caller (the MCP-Protocol-Version header plus the 2026-07-28 _meta envelope, no handshake) gets 2026-07-28, including the built-in server/discover method. Algenta pins the official Python MCP SDK 2.0.0. Deprecated /mcp/sse and /mcp/messages routes remain for older clients but are not the default.

LangChain example:

import os

from langchain_mcp_adapters.client import MultiServerMCPClient

client = MultiServerMCPClient(
    {
        "algenta": {
            "transport": "http",
            "url": "http://localhost:8001/mcp",
            "headers": {
                "Authorization": f"Bearer {os.environ['ALGENTA_API_KEY']}"
            },
        }
    }
)

tools = await client.get_tools()

Verify

The human-readable discovery route is available alongside the protocol endpoint:

curl -s http://localhost:8001/mcp/tools | jq '.tools | length'

In an MCP client, call get_contract first, then use list_data and get_data_summary before querying a dataset. Tool names, descriptions, and input schemas are returned by MCP tools/list.

Security

• Tool calls use Authorization: Bearer <ALGENTA_API_KEY> or the configured process credential.
• Streamable HTTP validates Host and Origin to prevent DNS-rebinding access.
• Standalone HTTP binds to loopback unless ALGENTA_MCP_HOST is explicitly changed.
• Error payloads redact API-key material.
• ALGENTA_BASE_URL is required when cloud access is disabled.
• Put an authenticating gateway in front of a publicly reachable standalone MCP port.

Compatibility

Canonical environment variables are ALGENTA_API_KEY and ALGENTA_BASE_URL. Legacy DE_API_KEY, DE_BASE_URL, and ALGENTA_API_URL remain accepted for existing deployments.
