SAP MCP Server

Production-oriented Model Context Protocol server for OOBE Synapse Agent Protocol, Solana, Synapse AgentKit, SNS, and monetized hosted agent workflows.

SAP MCP exposes the same typed tool registry through two supported MCP launch modes:

1. Local stdio for desktop agents and local development.
2. Remote Streamable HTTP at /mcp for hosted customers and orchestrators.

It also includes a professional setup wizard, profile-managed config under ~/.config/mcp-sap, optional Bento policy integration, local and external signing modes, x402 monetization, a self-hosted OOBE facilitator, pay.sh provider YAML generation, and an A2A-compatible discovery card.

User-facing setup docs live in USER_DOCS/. Operator and engineering docs live in docs/.

1. Status

2. Install

Prerequisites:

node --version   # >= 22.12.0
corepack enable
corepack prepare pnpm@11.7.0 --activate
pnpm --version   # 11.7.0

From source:

pnpm install
pnpm run build

Do not use npm install for source deployments. This repository is locked and verified with pnpm.

From the published package:

npm install -g @oobe-protocol-labs/sap-mcp-server

3. Quick Start

Create or select a profile:

npx sap-mcp-config wizard

Repair hosted SAP MCP runtime entries without recreating the profile:

npx sap-mcp-config repair

After connecting hosted SAP MCP in an agent runtime, start the agent context with one short message:

Start SAP MCP.

The agent should call the free sap_agent_start tool or sap-agent-start prompt, load sap_skills_bundle, and use the local sap_payments bridge for paid/write hosted calls.

Inspect the active profile:

npx sap-mcp-config show
npx sap-mcp-config doctor
npx sap-mcp-config pubkey
npx sap-mcp-config profiles

Start local stdio MCP:

sap-mcp-server

or from source:

node dist/cli.js

Hosted customers connect their agents to https://mcp.sap.oobeprotocol.ai/mcp, but signing remains user-controlled. The recommended setup for most users is the wizard-managed pair of MCP entries:

• sap: hosted Streamable HTTP SAP MCP at https://mcp.sap.oobeprotocol.ai/mcp;
• sap_payments: local non-custodial payment bridge for x402/pay.sh paid/write calls.

Any user who wants to pay x402/pay.sh charges, register or operate a SAP identity, or execute value-moving Solana/SAP tools should run the wizard first and keep the dedicated wallet under ~/.config/mcp-sap/keypairs/ or behind an external signer. Read-only hosted discovery can use the remote URL without a local signer.

4. Local Client Config

For local agents, let SAP MCP follow the active profile manager instead of hard-coding wallet paths or stale RPC overrides:

{
  "mcpServers": {
    "sap": {
      "command": "sap-mcp-server",
      "env": {
        "SAP_MCP_ALLOW_ENV_CONFIG_OVERRIDE": "false",
        "SAP_LOG_LEVEL": "info"
      }
    }
  }
}

Codex uses TOML rather than the JSON mcpServers shape. For hosted remote MCP, add this to ~/.codex/config.toml and restart Codex:

[mcp_servers.sap]
url = "https://mcp.sap.oobeprotocol.ai/mcp"

For paid/write hosted tools, add the local non-custodial payment bridge as well:

[mcp_servers.sap_payments]
command = "npx"
args = ["--yes", "--package", "@oobe-protocol-labs/sap-mcp-server@0.9.85", "sap-mcp-server"]
startup_timeout_sec = 300
tool_timeout_sec = 300

[mcp_servers.sap_payments.env]
SAP_MCP_ALLOW_ENV_CONFIG_OVERRIDE = "false"
SAP_MCP_PAYMENTS_BRIDGE_ONLY = "true"
SAP_ALLOWED_TOOLS = "all"
SAP_LOG_LEVEL = "info"

On Windows, use command = "npx.cmd". The wizard can write this automatically.

Codex supports Streamable HTTP MCP servers with URL-based entries in config.toml. Use local stdio through npx only when you specifically want Codex to launch the local SAP MCP process:

[mcp_servers.sap]
command = "npx"
args = ["--yes", "--package", "@oobe-protocol-labs/sap-mcp-server@0.9.85", "sap-mcp-server"]

[mcp_servers.sap.env]
SAP_MCP_ALLOW_ENV_CONFIG_OVERRIDE = "false"
SAP_LOG_LEVEL = "info"

On Windows, use command = "npx.cmd".

See 04. Local Stdio MCP Runbook.

5. Remote Server

Remote deployments expose MCP over Streamable HTTP:

node dist/remote/server.js

Production environment values should come from a private secret store or private deployment file, not from public docs. Public hosted agent-facing deployments can use SAP_MCP_AUTH_TYPE=none when x402, rate limits, and policy are enabled. API key or JWT auth remains available for private beta, enterprise, and admin deployments.

Remote endpoints:

GET     /
GET     /docs
GET     /server.json
GET     /favicon.png
GET     /favicon.ico
GET     /health
GET     /openapi.json
GET     /.well-known/x402
GET     /pay/provider.yml
GET     /.well-known/agent-card.json
GET     /.well-known/sap-mcp-wizard.json
GET     /.well-known/sap-mcp-tool-catalog.json
GET     /tool-catalog.json
GET     /wizard/install.sh
POST    /mcp
GET     /mcp
DELETE  /mcp

GET / is a public, share-safe landing page with Open Graph/Twitter metadata. It exposes only public server information; keypair bytes, private wallet paths, RPC query secrets, and VPS-local paths must never appear there.

GET /docs serves the public documentation site for install, start, configuration, hosted remote MCP, x402/pay.sh payments, and MCP client setup.

Marketplace listings such as Smithery can use smithery.config.schema.json to explain the hosted setup path. The schema intentionally asks for no secrets: SAP MCP hosted reads work remotely, while paid/write calls use the wizard-managed local sap_payments bridge, local profile policy, and user-controlled signer.

See 05. Hosted Streamable HTTP Deployment and 07. HTTP Endpoints, MCP Clients, And Smoke Tests.

6. Monetization

Hosted HTTP deployments can require payment for paid tools/call requests while leaving local stdio and base MCP protocol calls free.

Initial model:

Enable x402:

SAP_MCP_MONETIZATION_ENABLED=true
SAP_MCP_MONETIZATION_PROVIDER=x402
SAP_MCP_MONETIZATION_PAY_TO=YOUR_SOLANA_USDC_RECIPIENT
SAP_MCP_X402_FACILITATOR_URL=YOUR_PRIVATE_OR_HOSTED_FACILITATOR_URL

Initialize and run the OOBE facilitator:

npx sap-mcp-facilitator init
npx sap-mcp-facilitator start

Generate a pay.sh provider YAML:

The hosted public catalog is available at https://mcp.sap.oobeprotocol.ai/pay/provider.yml. It is secret-free and intended for pay.sh catalog/proxy discovery.

npx sap-mcp-pay-sh-spec \
  --out sap-mcp-pay-sh.yml \
  --upstream-url https://mcp.sap.oobeprotocol.ai \
  --network mainnet \
  --recipient YOUR_SOLANA_USDC_RECIPIENT

See 06. x402/pay.sh Monetization Settlement.

For local agent runtimes that cannot replay x402 challenges natively, install the wizard's local sap_payments bridge and call sap_payments_call_paid_tool. The legacy CLI helper is still available for terminal use:

npm exec --yes --package @oobe-protocol-labs/sap-mcp-server -- sap-mcp-x402-paid-call \
  --tool sap_list_all_agents \
  --arguments '{"limit":5}' \
  --max-usd 0.02 \
  --confirm

The helper signs payment payloads with the user's local SAP MCP profile and never sends keypair bytes to the hosted server.
