Context Mode
Context Mode is an MCP server that reduces context window waste by sandboxing data-heavy tools, tracking session state in SQLite, and promoting code-based analysis over raw data reads, achieving up to 98% context savings.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

esbuild allows arbitrary file read when running the development server on Windows

3 read-only tools perform write/delete/exec — ctx_search (line 517: unlinkSync(filePath)); ctx_stats (line 517: unlinkSync(filePath)); ctx_doctor (line 92: spawnSync("cmd.exe", ["/d", "/s", "/c", "codex plugin list"], {)
Either remove the readOnlyHint:true annotation, or remove the write/delete call from the tool handler.
Destructive tools are labelled
7 tools perform destructive updates without destructiveHint — ctx_index deletes at line 874 (unlinkSync(rp)); ctx_search deletes at line 517 (unlinkSync(filePath)); ctx_fetch_and_index deletes at line 874 (unlinkSync(rp))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Tool inputs are validated
10/11 tool handlers declare input schemas (91%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Shell command execution
59 child_process/subprocess calls in production code — runs shell commands (src/server.ts:92, src/server.ts:97, src/server.ts:4220)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Readable source code
2 files appear obfuscated
Ship unminified, readable source.
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
2/8 production deps stale: turndown-plugin-gfm@2022-05-22 (4.2y), @mixmark-io/domino@2024-04-08 (2.3y)

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
