docs: SAP MCP proxy demo (Vaara in front of community SAP MCP servers)#101
Merged
Conversation
Adds examples/sap-mcp-proxy-demo/ with a README walkthrough and a Claude Code MCP config example showing how to insert Vaara's runtime governance proxy in front of an existing community SAP MCP server (mario-andreschak/mcp-abap-abap-adt-api, SAP/mdk-mcp-server, lemaiwo/btp-sap-odata-to-mcp-server, or any other listed in marianfoo/sap-ai-mcp-servers). The demo targets an SAP architect already running Claude Code against a SAP MCP server and a real SAP system (BTP, S/4HANA, NetWeaver). It does not include or stub a SAP backend. The reader brings the SAP side; the demo brings the Vaara wiring. Three-step recipe: pip install vaara, replace the existing Claude Code MCP config entry with the Vaara proxy command in front of the same upstream MCP server, restart Claude Code. Every tools/call routes through Vaara's interception pipeline before reaching the upstream. Audit trail accumulates in a local SQLite DB and exports as AI Act Article 12 evidence via vaara compliance report / vaara trail export.

…ME section (#105) Two problems shipped in #100 and #101 that were fixed here: 1. README's MCP proxy code example used `npx --upstream-arg @sap/adt-mcp-server`, a fictional npm package. The MCP proxy block was also buried as a third-tier subsection under Framework integrations, despite v0.21.0 being the headline ship and having two worked demos. 2. SAP demo's example config used `npx -y @mario-andreschak/mcp-abap-abap-adt-api`, which is not published on npm. The real install path for that server is git clone + npm install + npm run build, then run with `node /path/to/dist/index.js`. Fixes: - README: removed the buried `### MCP proxy` subsection under Framework integrations and added a top-level `## MCP proxy` section between TypeScript client and OVERT. Uses `@sap/mdk-mcp-server` (verified on npm at version 0.3.7) as the one-line example. Links both demo folders. - examples/sap-mcp-proxy-demo/claude_code_config.example.json: primary `sap-mdk-via-vaara` block now uses the real `@sap/mdk-mcp-server` invocation. Sibling `_alternative_abap_adt` block uses the real `node /PATH_TO_YOUR/mcp-abap-abap-adt-api/dist/index.js` invocation. Sibling `_alternative_btp_odata` block clarified as clone+build. - examples/sap-mcp-proxy-demo/README.md: prereqs section names each upstream's real install path. Before/After config blocks now show the real MDK invocation. Note steering ABAP/OData readers to the alternative blocks in the example config. Verified upstreams via npm registry and GitHub API: `@sap/mdk-mcp-server` is published, official, Apache-2.0; `mario-andreschak/mcp-abap-abap-adt-api` is on GitHub (134 stars, MIT) but not on npm; `SAP/mdk-mcp-server` repo is Apache-2.0, 31 stars.
