Overview

This release improves middleware reliability with integration tests, adds comprehensive audit logging documentation, and reorganizes the docs site navigation for better discoverability.

Improvements

Middleware Chain Integration Test (#50)

Added an end-to-end integration test that wires a real mcp.Server with all middleware via AddReceivingMiddleware and sends a real tools/call request through the chain. This validates that context propagation works correctly across the full middleware stack:

  • Verifies audit store receives complete events with non-empty UserID, ToolName, ToolkitKind, PersonaName, Duration, and Success
  • Catches regressions in middleware ordering that unit tests cannot detect

Refactored Middleware Initialization

finalizeSetup() in pkg/platform/platform.go is reorganized with clear comments documenting the execution order. Middleware is added innermost-first so the last-added runs first:

  1. Semantic enrichment (innermost)
  2. Rule enforcement
  3. Audit (reads PlatformContext)
  4. Auth/Authz (creates PlatformContext, outermost to audit)
  5. Apps metadata (outermost)

Documentation

New: Audit Logging Guide

Full documentation at docs/server/audit.md covering:

  • PostgreSQL prerequisites and schema
  • Configuration options (audit.enabled, audit.log_tool_calls, audit.retention_days)
  • Fallback behavior (stderr JSON when database is unavailable)
  • Retention policy and cleanup
  • Query examples and troubleshooting

Updated: Middleware Reference

Expanded docs/reference/middleware.md with:

  • Execution order diagram
  • Context propagation details
  • Documentation for new middleware components (rules, toolkit lookup, apps metadata)

Reorganized Docs Navigation

Reduced top-level tabs from 11 to 7 for a clearer information architecture:

Before After
Home, Concepts, MCP Server, Cross-Injection, Authentication, Personas, Go Library, MCP Apps, Examples, Reference, Support Home, Getting Started, Features, Go Library, Examples, Reference, Support
  • Getting Started absorbs Concepts and server setup pages (overview, installation, configuration, deployment)
  • Features groups Cross-Injection, Authentication, Personas, Audit Logging, MCP Apps, Tools, and Multi-Provider
  • Previously orphaned cross-injection/lineage.md now included in nav

Updated Homepage

Added 2 feature cards to the homepage (4 → 6, rendering as a 3x2 grid):

  • Audit Logging — PostgreSQL-backed tool call logging
  • MCP Apps — Interactive UI components for tool results

LLM-Readable Docs

  • Added audit logging section to docs/llms-full.txt
  • Added link in docs/llms.txt
