Side-by-Side Model Context Protocol Comparison
Ctxfile vs Agent Recall
In-depth architectural comparison of the Ctxfile and Agent Recall 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
Ctxfile
Knowledge & Memory · Local stdio
Quality: 57/100 (Good) | Auth: No auth required
Agent Recall
Knowledge & Memory · Local stdio
Quality: 68/100 (Great) | Auth: No auth required
Verdict Summary: Choose Ctxfile if you need specialized Knowledge & Memory tools running via a local process. Choose Agent Recall 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 Ctxfile 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).
Local-first MCP server that snapshots your project's working state — files, git, plan, and decisions — into one structured context object and hands it to any MCP client in a single call. Save a session in one agent, continue it in another. Zero network calls by default; read-only over your project. Works with Claude Code, Cursor, and any MCP client. npx -y ctxfile
[ENTRY — call FIRST, before acting] Use when the user asks to start, load, continue, resume, or open memory for a project. Set mode='lite' for a ≤500-token briefing (good for fresh conversations where the agent will pull memory on demand via recall()).
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Ctxfile is categorized under Knowledge & Memory and uses a local stdio subprocess. In contrast, Agent Recall belongs to Knowledge & Memory using local stdio subprocess. Select Ctxfile when you need capabilities focused on knowledge & memory and Agent Recall when you require tools for knowledge & memory.
[ON SAVE/EXIT — YOU must call this; nothing auto-saves] Use when the user asks to save, checkpoint, summarize, end, retain, or persist the current session. Optionally pass close_phase / open_phase to update the project pipeline narrative spine in the same call.
remember
[MID-SESSION WRITE — single fact/decision; saying it is not saving it] Use when the user asks to remember, store, note, or save a specific decision, fact, or insight.
recall
[RETRIEVE — use freely, any time] Use when the user asks to recall, search, find, or look up previous memory, context, or decisions.
check
[MID-SESSION — safe any time; for alignment, before risky decisions] Use when the user asks to validate understanding, verify alignment, or check if their interpretation matches the human's intent. Also call BEFORE a high-risk action — publish, deploy, delete, credential exposure, external send/message, or any other irreversible write — passing `action_description` (one sentence, what you're about to do). Returns matching corrections/rules/insights plus a `verdict`: `blocked` means an authoritative correction OVERRIDES the plan — read it before proceeding. To RECORD a durable human correction, pass `human_correction` as the STRUCTURED object {rule, why, applies_when} — a plain string is only STAGED for later review, never activated.
