Memex vs Codebase Memory MCP — MCP Server Comparison | AllMCPs
Side-by-Side Model Context Protocol Comparison
Memex vs Codebase Memory MCP
In-depth architectural comparison of the Memex and Codebase Memory MCP MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Memex
Knowledge & Memory · Local stdio
Quality: 63/100 (Good) | Auth: No auth required
Codebase Memory MCP
Knowledge & Memory · Local stdio
Quality: 72/100 (Great) | Auth: No auth required
Verdict Summary: Choose Memex if you need specialized Knowledge & Memory tools running via a local process. Choose Codebase Memory MCP if your workspace requires Knowledge & Memory integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Memex when:
You need dedicated capabilities in the Knowledge & Memory domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Developer context continuity system. Watches your git repos and builds a temporal knowledge graph of modules, symbols, decisions, and open problems via Graphiti + Neo4j, then serves it to any AI coding agent over MCP. Every edge carries a validity window and a confidence score that decays over time. 12 tools across read and write. Install via npx -y stifler-memex-mcp. MIT licensed.
Code-intelligence engine that indexes a repo into a persistent knowledge graph — functions, classes, call chains, HTTP routes, cross-service links. 159 languages via tree-sitter + Hybrid LSP, sub-ms structural queries, 99% fewer tokens than grep. Single static binary, zero dependencies, 100% local. npx codebase-memory-mcp
Tools & Capabilities Breakdown
Memex Tools (12)
get_project_context
Session start. Returns a cluster-level briefing under 1500 tokens regardless of repo size
get_symbol_context
Before editing a function or class. Returns callers, callees, linked decisions
get_recent_decisions
Last N days of architectural decisions, optionally module-scoped
Memex is categorized under Knowledge & Memory and uses a local stdio subprocess. In contrast, Codebase Memory MCP belongs to Knowledge & Memory using local stdio subprocess. Select Memex when you need capabilities focused on knowledge & memory and Codebase Memory MCP when you require tools for knowledge & memory.
Given a commit SHA, cross-references the diff with linked Decision/Problem nodes and asks Gemini Pro for a grounded explanation
predict_impact
Given a file path, returns a ranked list of modules likely affected based on graph coupling (no LLM call)
record_decision
After making a technical choice. Supports `corroborates` (reinforce) and `supersedes` (replace)
record_problem
When discovering a bug or piece of tech debt
resolve_problem
When a tracked problem is fixed
invalidate_edge
When a stored fact is no longer true
Codebase Memory MCP Tools (14)
index_repository
Index a repository into the graph. Auto-sync keeps it fresh after that.
list_projects
List all indexed projects with node/edge counts.
delete_project
Remove a project and all its graph data.
index_status
Check indexing status of a project.
search_graph
Structural, BM25, and semantic search. Page structural rows with `offset`/`limit` and ranked semantic rows independently with `semantic_offset`/`semantic_limit`.
trace_path
BFS traversal — who calls a function and what it calls (alias: `trace_call_path`). Depth 1-5.
detect_changes
Map git diff to affected symbols + blast radius with risk classification.
query_graph
Execute Cypher-like graph queries (read-only).
get_graph_schema
Node/edge counts, relationship patterns, property definitions per label. Run this first.
get_code_snippet
Read source code for a function by qualified name.
