# SAP MCP Server

An MCP server that gives your agent typed tools for Solana and the SAP protocol, over local stdio or remote Streamable HTTP. Useful when the agent has to read chain data and pay for calls.

## What it does

SAP MCP Server publishes one typed tool registry through two launch modes: a local stdio process and a remote Streamable HTTP endpoint at `/mcp`. Hosted agents point at `https://mcp.sap.oobeprotocol.ai/mcp`, while transaction signing stays in the user's hands.

A setup wizard manages profiles under `~/.config/mcp-sap`. There are local and external signing modes, optional Bento policy, x402 monetization, and generation of a pay.sh provider config. Paid and write calls need the separate local `sap_payments` bridge; without it those tools will not go through. The agent wallet lives in `~/.config/mcp-sap/keypairs/`, and the wizard leaves the Solana CLI keypair alone.

Building from source means pnpm only: Node.js 22.12.0 or newer plus pnpm 11.7.0. `npm install` is not the path here, the repository is locked to pnpm. Read-only remote discovery works without a local signer.

## Requirements
- Needs: Node.js (commands run via npx)
- Remote server: `https://mcp.sap.oobeprotocol.ai/mcp`
- Environment variables: `SAP_MCP_ALLOW_ENV_CONFIG_OVERRIDE`, `SAP_LOG_LEVEL` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- wire an agent into Solana over MCP
- split read-only calls from paid ones across two servers
- set up an agent wallet profile without touching the Solana CLI keypair
- charge for tool calls through x402
- run a remote MCP endpoint for hosted agents

## Example prompts
- Start SAP MCP.
- Show the active profile and run `npx sap-mcp-config doctor` on it.
- Create a new profile with `npx sap-mcp-config wizard`.
