What it gives an agent

A purpose-built capability behind one MCP connection.

The server owns its domain logic and publishes a tool contract an MCP client can discover. ADK-Rust can load that contract into an agent, normalize each schema for the chosen model provider, and keep the connection lifecycle outside the agent’s business logic.

CEL-powered rules — pricing rules use Common Expression Language for type-safe, auditable conditions.

Price waterfall — deterministic 6-step pipeline: list → segment → promotions → rules → floor/ceiling → tax.

Explain mode — every price calculation can return the full waterfall breakdown showing which rule caused each price movement.

Vertical-agnostic — same engine prices rides, SaaS subscriptions, physical goods, API calls, and professional services.

Audit everything — every rule change, product update, and quote approval is logged immutably.

Zero configuration — starts with no external dependencies. Market intel (FX rates) works immediately via free APIs.

Architecture

How Pricing Engine MCP Server fits into an agent system.

The model never needs the implementation details or credentials of the system behind the server. It sees reviewed tool definitions. The MCP client handles discovery and calls, while the server keeps ownership of validation, policy, and communication with its domain system.

ADK-Rust agent

Chooses a capability from the reviewed tool catalog.

→

MCP client

Discovers schemas, sends calls, and receives typed content.

→

Pricing Engine MCP Server

Validates the request and owns 21 documented tool contracts.

→

Domain system

Keeps the API, data, credentials, and business rules behind the server.

Tool catalog

What can an agent ask Pricing Engine MCP Server to do?

Each tool has a stable name, a human-readable purpose, and a JSON input contract discovered during MCP initialization. Risk classes come from the project’s registry manifest when one is available.

Governance

Understand the effect of every tool.

A server connection inherits the authority of its credentials and deployment environment. The declarations below come from this project’s README and MCP registry manifest; your application still decides which tools an agent receives and where approval is required.

MCP surface

What the current documentation declares.

MCP can carry tools, resources, prompts, structured results, progress, cancellation, and long-running work. This record highlights the modern protocol features explicitly mentioned by this repository.

Install and connect

Follow the project’s documented starting point.

Install the server in the environment that owns its credentials and domain access. Add it to your MCP host, verify the discovered tools, and narrow the toolset before giving it to a production agent.

Install

cargo install mcp-pricing

MCP client configuration

{
  "mcpServers": {
    "pricing": { "command": "mcp-pricing" }
  }
}

Commands and configuration are extracted from the public README. Confirm prerequisites, environment variables, and release-specific options in the official documentation before deployment.
