Context Mode vs PatchWarden
A side-by-side look at the Context Mode and PatchWarden MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
C
Context ModeCoding AgentsContext window optimization for AI coding agents. Sandboxes tool output (98% reduction), persists session memory, and enforces routing across 17 platforms via MCP + hooks.57GoodAuth: no auth requiredVerdict: choose Context Mode for coding agents work; choose PatchWarden for coding agents as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
CChoose Context Mode when
- You need dedicated capabilities in the Coding Agents domain.
- Its auth model fits you: No auth required.
- You want tools like
ctx_batch_execute, ctx_execute, ctx_execute_file.
Choose PatchWarden when
- You need dedicated capabilities in the Coding Agents domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
CONTROL_PLANE_API_KEY, PATCHWARDEN_OWNER_TOKEN. - You want tools like
save_plan, get_plan, health_check.

Tools & capabilities
Context Mode tools 10
ctx_batch_executeRun multiple commands + search multiple queries in ONE call. Opt-in `concurrency: 1-8` for I/O-bound batches.ctx_executeRun code in 12 languages. Only stdout enters context.ctx_execute_fileProcess files in sandbox. Raw content never leaves.ctx_indexChunk markdown into FTS5 with BM25 ranking.ctx_searchQuery indexed content with multiple queries in one call.ctx_fetch_and_indexFetch URL, chunk and index. Cache reuses content within TTL (default 24h, override per-call with `ttl: <ms>`). `ttl: 0` or `force: true` to bypass. Pass `requests: [{url, source}, ...]` + `concurrency: 1-8` for parallel multi-URL.ctx_statsShow context savings, call counts, and session statistics.ctx_doctorDiagnose installation: runtimes, hooks, FTS5, versions.ctx_upgradeUpgrade to latest version from GitHub, rebuild, reconfigure hooks.ctx_purgePermanently deletes all indexed content from the knowledge base.
PatchWarden tools 30
save_planSave an execution plan — ChatGPT writes the plan, PatchWarden stores it for local agent execution. Supports plan_ref to load a plan file already placed inside .patchwarden/plans.get_planRead a saved plan by its plan_id.health_checkCheck MCP catalog consistency, watcher freshness/supervisor state, workspace readiness, and configured agents. Use detail=self_diagnostic for expanded read-only evidence.list_agentsList configured local agents and check whether each executable currently exists. This does not start an agent or contact its model provider.create_taskCreate a repo-scoped task from exactly one source. For ChatGPT, prefer the guarded inspect_only, feature_small, or fix_tests template when it fits. A stale watcher preserves the task but returns execution_blocked and directs the client to health_check; otherwise call wait_for_task until terminal. Use execution_mode=assess_only to pre-assess risk and get an assessment_id without creating a task; then invoke the returned next_tool_call using only execution_mode=execute and the full assessment_id.get_task_statusCheck task status, execution phase, watcher health, pending reason, current command, timeout, and change evidence.get_resultRead result.md, or return structured availability and watcher evidence while the task is not terminal.get_result_jsonRead the structured result.json for deterministic task acceptance.get_diffRead task diff evidence, or return structured availability and watcher evidence while it is not ready.get_test_logRead test.log, or return structured availability and watcher evidence while it is not ready.list_workspaceList files and directories within the workspace (sensitive files excluded).read_workspace_fileRead a file within the workspace. Sensitive files (secrets, keys, tokens) are blocked. In Direct mode (with session_id), reads are scoped to the session's repo_path and return sha256.- +18 more on the listing page

Frequently asked questions
Context Mode is categorized under Coding Agents and uses an install path we have not confirmed yet. PatchWarden belongs to Coding Agents and uses a local stdio subprocess. Pick Context Mode for coding agents work and PatchWarden for coding agents.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client. Context Mode has no confirmed install command yet — follow its own setup instructions.
Context Mode is listed as free. Auth: no auth required. PatchWarden has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add context-mode and jiezeng2004-design-patchwarden as separate keys in the same mcpServers object, and your assistant will call tools from either one.
