How do I install the memex mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `GEMINI_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Memex MCP Server?

Temporal knowledge graph of your codebase (Graphiti + Neo4j), served to AI agents via MCP.

What the server does

A daemon and MCP server that turns every commit and every file change into structured graph state: modules, symbols, decisions, problems, lockfile facts. Sessions stop starting blind. Agents stop re-discovering the same refactor every time you /clear.

More MCP options

Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.

Recorded tools

Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.

Tool	What it does
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
get_open_problems	Active bugs and tech debt, sorted by severity
search_context	Hybrid search: semantic × keyword × graph traversal × RRF merge
get_stale_context	Edges whose composite confidence dropped below threshold
explain_change	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
