How to install ReasonGraph Cloud memory in Claude CodeAnthropic's agentic CLI
Add the server
bashclaude mcp add --transport http reasongraph https://memory.primaxiom.ai/mcp --header 'Authorization: Bearer <YOUR_TOKEN>'Fill in your credentials
Replace Bearer <YOUR_TOKEN> with your real value. Keep secrets out of any config file you commit.
Verify it's connected
bashclaude mcp listSharing it with your team?
Add `--scope project` to write it to .mcp.json in the repository root, which you can commit (with the secrets left as environment variables).
Use it in a session
Ask Claude to use the tools this server exposes. It discovers them automatically.
How to install ReasonGraph Cloud memory in Claude DesktopDesktop app (MCP config)
Open your MCP config
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json
Add this server
json{ "mcpServers": { "reasongraph": { "command": "npx", "args": [ "-y", "mcp-remote", "https://memory.primaxiom.ai/mcp", "--header", "Authorization:${AUTH_HEADER}" ], "env": { "AUTH_HEADER": "Bearer <YOUR_TOKEN>" } } } }Fill in your credentials
Replace Bearer <YOUR_TOKEN> with your real value. Keep secrets out of any config file you commit.
Why the wrapper?
This is a remote (HTTP) server and Claude Desktop only launches local processes, so mcp-remote proxies the connection. It will open a browser window if the server needs OAuth.
Restart Claude Desktop
The tools appear under the 🔌 menu once the app reloads.
How to install ReasonGraph Cloud memory in CursorAI-first code editor
Create / edit .cursor/mcp.json in your project
json{ "mcpServers": { "reasongraph": { "url": "https://memory.primaxiom.ai/mcp", "headers": { "Authorization": "Bearer <YOUR_TOKEN>" } } } }Fill in your credentials
Replace Bearer <YOUR_TOKEN> with your real value. Keep secrets out of any config file you commit.
Enable it
Cursor Settings → MCP → toggle the server on. Tools become available to the Composer/Agent.
How to install ReasonGraph Cloud memory in Codex CLIOpenAI coding agent
Add to ~/.codex/config.toml
toml[mcp_servers.reasongraph] command = "npx" args = ["-y", "mcp-remote", "https://memory.primaxiom.ai/mcp", "--header", "Authorization:${AUTH_HEADER}"] env = { AUTH_HEADER = "Bearer <YOUR_TOKEN>" }Fill in your credentials
Replace Bearer <YOUR_TOKEN> with your real value. Keep secrets out of any config file you commit.
Why the wrapper?
Codex runs MCP servers as local processes, so mcp-remote bridges this HTTP endpoint to stdio.
Run Codex
Codex loads MCP servers from config.toml on startup and exposes their tools to the agent.
How to install ReasonGraph Cloud memory in WindsurfCodeium's agentic IDE
Edit ~/.codeium/windsurf/mcp_config.json
json{ "mcpServers": { "reasongraph": { "serverUrl": "https://memory.primaxiom.ai/mcp", "headers": { "Authorization": "Bearer <YOUR_TOKEN>" } } } }Fill in your credentials
Replace Bearer <YOUR_TOKEN> with your real value. Keep secrets out of any config file you commit.
Reload
Windsurf → Cascade → refresh MCP servers. Cascade can now call the tools.
How to install ReasonGraph Cloud memory in ClineVS Code autonomous agent
Open Cline → MCP Servers → Configure
Adds to cline_mcp_settings.json.
Add the server
json{ "mcpServers": { "reasongraph": { "type": "streamableHttp", "url": "https://memory.primaxiom.ai/mcp", "headers": { "Authorization": "Bearer <YOUR_TOKEN>" } } } }Fill in your credentials
Replace Bearer <YOUR_TOKEN> with your real value. Keep secrets out of any config file you commit.
How to install ReasonGraph Cloud memory in VS CodeCopilot / MCP support
Create .vscode/mcp.json
json{ "servers": { "reasongraph": { "type": "http", "url": "https://memory.primaxiom.ai/mcp", "headers": { "Authorization": "Bearer <YOUR_TOKEN>" } } } }Fill in your credentials
Replace Bearer <YOUR_TOKEN> with your real value. Keep secrets out of any config file you commit.
Start it
VS Code shows a ▶ Start action above the server entry. Agent mode (Copilot Chat) can then use the tools.
What does ReasonGraph Cloud memory need from you?

What tools does ReasonGraph Cloud memory expose?
This server requires credentials before it will list its tools, so we cannot enumerate them here. Connect it in your client to see what it offers.
What the code can do
This is a remote server — nothing is installed or run on your machine, so there is no local code to analyze. What it can reach is described above: your requests go to the provider's host.

Full READMEReasonGraph
A graph-based memory for AI agents: it ingests facts, auto-extracts entities and cause->effect relations, and discovers connections across independent documents *and* across agent sessions -- with conflict resolution, time-travel, causal tracing, and counterfactuals.
Why ReasonGraph?
Standard RAG retrieves documents similar to your query. ReasonGraph is a persistent, updatable memory that discovers connections *between* facts that were written independently.
When you feed text into add_texts(), ReasonGraph automatically extracts entities (via GLiNER) and cause-effect relations (via a dedicated causal model) that become nodes and typed edges in a graph. Facts that share entities or causal chains get connected -- even if they never reference each other. Multi-hop traversal then walks these connections to build reasoning chains that span multiple sources.
On top of retrieval it works as agent memory: scopes/sessions (agents discover into each other's memory through shared entities), contradiction resolution (a new fact soft-supersedes what it contradicts), time-travel (query(as_of=...)), causal tracing (trace_effects / root_causes / causal_chain), counterfactuals (what_if), and a shippable MemoryService over HTTP and MCP.
Zero config, strong defaults. ReasonGraph() picks the best available entity extractor, causal model, embedder, and reranker automatically -- the eval numbers below come from these defaults. For the SOTA causal model (~0.70 F1) use pip install reasongraph[causal] and the graph uses it automatically. The configuration sections are optional depth, not required reading.
