Context Mode vs Wiff

A side-by-side look at the Context Mode and Wiff MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.

Context Mode logoContext ModeCoding Agents · Local subprocess (stdio)Context window optimization for AI coding agents. Sandboxes tool output (98% reduction), persists session memory, and enforces routing across 17 platforms via MCP + hooks.69GreatAuth: no auth requiredWiff logoWiffCoding Agents · Local subprocess (stdio)Deterministic, resumable multi-agent Codex workflows, drivable from any MCP client.60GoodAuth: not declared

Verdict: choose Context Mode for coding agents work as a local process; choose Wiff for coding agents as a local process. You can also run both side by side in one mcpServers block.

Wiff logoChoose Wiff when

  • You need dedicated capabilities in the Coding Agents domain.
  • You prefer a local stdio subprocess transport.
  • You have the keys it needs: WIFF_BACKEND.
  • You want tools like workflow_start, workflow_status, workflow_wait.

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.

Wiff tools 5

  • workflow_startLaunch a deterministic JavaScript workflow in the background, or resume a previous run without repeating successful unchanged agent calls. User and project preferences are loaded from Wiff config. Always pass the caller's absolute working directory as cwd.
  • workflow_statusRead the latest persisted status, phase, counters, result, and artifact paths for a workflow run.
  • workflow_waitWait until a workflow changes state or the timeout elapses. Call repeatedly until the run is completed, failed, cancelled, or interrupted.
  • workflow_cancelInterrupt all live agents and mark a workflow run cancelled.
  • workflow_modelsList the models each agent backend (codex, claude, cursor, kimi) can run, with supported reasoning efforts. Backends that are unavailable on this machine report an error instead of models.

Frequently asked questions

Context Mode is categorized under Coding Agents and uses a local stdio subprocess. Wiff belongs to Coding Agents and uses a local stdio subprocess. Pick Context Mode for coding agents work and Wiff 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 is listed as free. Auth: no auth required. Wiff 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 wiff as separate keys in the same mcpServers object, and your assistant will call tools from either one.
