Three pieces, all required for an end-to-end MCP tool call:
* McpToolService used generic spec names "request"/"response" instead of
"mcp-tool-request"/"mcp-tool-response", so RequestResponseSpec's
flow-config topic lookup never matched and consumers bound to literal
subjects nobody else publishes to.
* Add entrypoints/mcp-tool.mjs (mirrors agent/librarian entrypoints) so
the service can be launched in the prebuilt trustgraph-ts image.
* Add a `mcp-tool` service block to deploy/docker-compose.yml.
With these three fixes plus a `mcp-tool-request`/`mcp-tool-response`
entry in each flow's topics map, the agent ReAct loop can now invoke
remote MCP tools (verified end-to-end against Brave Search and FireCrawl).

ConfigApi.putConfig and deleteConfig (and the duplicate in FlowsApi) sent
a flat values:[{type,key,value}] array and a keys:{type,key} object —
neither matches the ConfigService schema, which requires keys:[namespace,
...innerKeys] and values:Record<string,unknown>. Every save in the
workbench /mcp-tools page returned `Put requires at least one key
(namespace)`.
putConfig now groups items by type (namespace) and issues one put per
group; deleteConfig sends keys:[type, key].

Pipeline fixes:
- Fix agent getting empty response from graph-rag by combining answer +
explain data in single message (RequestResponse returns first msg)
- Fix Doc RAG pipeline: add content field to Qdrant doc payload, seed 10
document chunks, fix type mismatches across base/flow/client
- Forward explainability events from agent's KnowledgeQuery to client
- Add "agent" to TERM_BEARING_RESPONSE_SERVICES for triple translation
- Fix embeddings env var (OLLAMA_URL), user/collection threading, edge
scoring threshold, and various protocol mismatches
Branding:
- Rename TrustGraph → Beep Graph (title, sidebar, settings, about)
- Custom lambda + ThugLife pixel glasses SVG logo component
- Forest green color palette (brand-50 through brand-900)
- SVG favicon + PNG icons (16/32/180/192/512)
- PWA manifest with service worker for offline shell caching
- Splash screen with animated logo pulse on app load
- Ambient glow background with drifting green radial blobs

Add chat UX improvements: message actions toolbar (copy/delete/regenerate)
on hover, inline explainability subgraph visualization from RAG/agent
queries, and token metadata for all chat modes. Enhance graph page with
SPO query filters, configurable triple limit, and type legend overlay.
Extract shared graph utilities for reuse across components.

Add dedicated /mcp-tools page for managing MCP servers and tools from the
workbench. Includes CRUD dialogs, config API integration, and feature flag
gating via mcpTools switch. QA pass also fixes accessibility across existing
pages: aria-expanded on chat phase blocks, tabpanel tabindex on prompts,
toggle contrast ratio (WCAG 2.1 SC 1.4.11) on settings.

- Add global focus-visible outline for buttons, switches, selects, and
inputs so all interactive elements show a visible brand-500 ring on
keyboard focus (not just NavLinks and dialog close)
- Darken light-mode --color-border from #e4e4e7 to #d4d4d8 so input
borders, dividers, and mode selector outlines are visible on white

Add the full MCP tool pipeline enabling agents to invoke external tools
(like Brave Search) via MCP servers:
- Add ToolRequest/ToolResponse types and mcp-tool topics to @trustgraph/base
- Create McpToolService (FlowProcessor) that connects to external MCP servers
via @modelcontextprotocol/sdk StreamableHTTP transport
- Add createMcpTool() to wire MCP tools into the agent's ReAct loop
- Implement config-driven tool registration in AgentService with backward-
compatible fallback to hardcoded tools
- Add tool filtering by group and state (port of Python tool_filter.py)
- Register mcp-tool in gateway dispatcher and export from @trustgraph/flow
- Fix flow restart race condition: skip restart when flow definitions unchanged
- Update seed config with MCP server config and tool definitions
- Add run scripts for MCP tool service and Brave Search MCP server

- Fix FalkorDB triples query: client v5 returns objects not arrays, use named field access
- Fix embeddings service: align spec names to "embeddings-request"/"embeddings-response"
- Fix client triplesQuery: read `triples` field instead of `response` from backend
- Fix graph page crash: guard against non-array triples, accept literals as entity nodes
- Add seed:demo script for AI industry knowledge graph (254 triples, 64 entities)

Store the initialization Promise in the requestors map synchronously
before yielding, so concurrent callers for the same key await the same
instance — prevents orphaned RequestResponse objects and duplicate NATS
subscriptions. Mirrors upstream fix 8f18ba02.

Three QA iterations to convergence (zero issues remaining):
Workbench UI:
- Connection badge: amber "Connected (no auth)" for unauthenticated state
- Theme persistence: restore script in index.html + localStorage sync
- Settings About section: add bottom padding so content isn't clipped
- Clear messages: cancel in-flight requests when clearing chat
- Feature switch labels: proper casing + acronym handling (MCP, LLM)
- Token Cost badge: hidden during loading state
- ARIA: role="switch", aria-checked on toggles, aria-labels on buttons
- ConfigApi: null-safe chaining for getPrompts/getSystemPrompt
Grafana dashboards:
- Auto-refresh 30s on all 3 dashboards
- Panel heights reduced to fit viewport without scrolling
- Anonymous role upgraded to Editor for Explore access
Infrastructure:
- Nginx: DNS resolver with variable-based upstream (prevents crash loop)
- Workbench port set to 3002 in .env
