Mcp Tools

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.).

MCP Plugin Quick Reference

| Plugin | Transport | Key Tools | Agents | |--------|-----------|-----------|--------| | context7 | stdio | mcp__context7__resolve-library-id, mcp__context7__get-library-docs | researcher, developer | | playwright | stdio | mcp__playwright__browser_navigate, mcp__playwright__browser_screenshot | developer, debugger | | eslint | stdio | mcp__eslint__* | developer, reviewer | | sonarqube | docker | mcp__sonarqube__* | developer, reviewer | | memory | stdio | mcp__memory__* | developer, architect | | sequential-thinking | stdio | mcp__sequential-thinking__* | architect, debugger | | postgres-mcp | stdio | mcp__postgres-mcp__* | developer, optimizer | | redis-mcp | stdio | mcp__redis-mcp__* | developer, devops, debugger | | docker | stdio | mcp__docker__* | devops | | cron | stdio | mcp__cron__* | devops | | ssh-mcp | stdio | mcp__ssh-mcp__* | devops | | github | http | mcp__github__* | gitops, architect | | google-sheets | stdio | mcp__google-sheets__* | researcher, tech-writer | | slack | sse | mcp__slack__* | tech-writer | | asana | sse | mcp__asana__* | architect | | supabase | http | mcp__supabase__* | optimizer | | firebase | stdio | mcp__firebase__* | devops, optimizer | | semantic-memory | stdio | mcp__semantic-memory__semantic_search, mcp__semantic-memory__semantic_store, mcp__semantic-memory__semantic_recall | all agents (see below) |

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 | |-----------|---------------------|----------| | Library docs lookup | context7 | WebSearch | | 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 |
