MCP Tools Decision Tree

Priority Order

1. Does an MCP tool exist for this operation? Use it first.
2. Did the MCP tool fail (auth missing, plugin unavailable)? Fall back to built-in.
3. No MCP tool matches? Use built-in tools (Bash, Grep, WebSearch, etc.).

Semantic Memory MCP

• Transport: stdio (Python, venv/bin/python -m mcp_servers.semantic_memory)
• Source: MCP servers in your backend directory (internal, built on fastmcp)
• Auth: DATABASE_URL (PostgreSQL connection string), SEMANTIC_MEMORY_ENABLED=true
• Config: .mcp.json at project root

Tools

Tool	Purpose	Parameters
semantic_search	Search memories by similarity	query (required), project_id, agent_name, top_k, threshold
semantic_store	Store a new memory with embedding	content (required), agent_name (required), project_id, conversation_id, task_id, tags, content_type
semantic_recall	Recall relevant memories as markdown	context (required), agent_name, project_id, top_k

Access Control

Permission	Agents
Read + Write (all 3 tools)	developer, architect, debugger, analyst, researcher, reviewer, optimizer
Read-only (semantic_search, semantic_recall)	tech-writer, devops, gitops

For detailed usage guidance (when to search, when to store, quality gates), see the semantic-memory-mcp skill.

Fallback Strategy

Operation	MCP Tool (Priority)	Fallback

UI verification	playwright	Manual browser check
Code quality	sonarqube	python3 devops/sonarqube.py via Bash
Linting	eslint	npx eslint via Bash
Database query	postgres-mcp	psql via Bash
Cache inspection	redis-mcp	redis-cli via Bash
Container ops	docker	docker via Bash
Git operations	github	gh CLI via Bash
Memory search	semantic-memory	File-based agent-memory
Remote server	ssh-mcp	ssh via Bash
