How to Use the Context Engineering Prover MCP in Windsurf

Q: Where do I configure the Context Engineering Prover in Windsurf?

Open /.codeium/windsurf/mcpconfig.json and add the server configuration under the mcpServers key. You can also use the Settings UI under Cascade to add the endpoint and refresh your active tools.

Q: Can Context Engineering Prover run automatically before Windsurf edits files?

Yes, you can instruct Cascade to run validatecontextengineering as the first step in any multi-file editing sequence. This ensures your agent is working with prioritized, high-density context before it attempts to write code.

Stop Cascade from wasting 64,000 tokens per run by forcing the Context Engineering Prover to audit every prompt block.

Prevent Cascade from dumping raw files into prompt contexts

The `validate_context_engineering` tool forces Windsurf to run a hard removal test on every code block before Cascade launches a multi-step execution chain. Instead of letting your agent fetch entire directories and dump 80,000 tokens into the LLM, this tool forces it to justify why each block is there and what breaks if it is removed. You get immediate visibility into your token waste ratio. Cascade must prioritize critical context first, placing system schemas and core logic in high-attention positions while pruning unreferenced noise.

Enforce strict token budgets on autonomous Windsurf chains

The `validate_context_engineering` tool stops Cascade from blowing through your API budget on long, multi-tool loops. It establishes a hard token budget with a minimum 10% response headroom, ensuring Windsurf has enough output space to complete complex refactoring tasks without hitting context limits. This MCP Server analyzes your context structure, flagging when middle-position tokens are decaying in value. It guarantees that Cascade only passes structured, high-density prompts to the underlying model.

Measure Windsurf task accuracy with an MCP Server

The `validate_context_engineering` tool replaces subjective evaluation with verifiable metrics directly inside your Windsurf workspace. Instead of relying on Cascade to decide if an output looks correct, this server forces your agent to ground its decisions in test suites and baseline-to-target accuracy deltas. It tracks metrics like task accuracy moving from 62% to 85% across your evaluation suites. You stop guessing if prompt adjustments worked and start engineering reproducible context pipelines.

Setup guide

Set up Context Engineering Prover MCP in Windsurf

Prerequisites

Windsurf IDE installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Click the Cascade assistant icon in the sidebar, then click the hammer icon (🔨) at the top of the panel. Select "Configure" to open ~/.codeium/windsurf/mcp_config.json.
2

Add the Context Engineering Prover MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
4

Verify in Cascade

Start a new Cascade conversation and ask something like "Show my Context Engineering Prover payment history." If connected, Cascade will call the Context Engineering Prover tools directly. You will see a green dot next to the server name in the MCP panel.

Common questions about Context Engineering Prover MCP in Windsurf

It intercepts Cascade before it sends a multi-step prompt, forcing it to run `validate_context_engineering`. The tool audits your context blocks, stripping out unreferenced noise so Windsurf only pays for tokens that actively drive the task.

Open `~/.codeium/windsurf/mcp_config.json` and add the server configuration under the `mcpServers` key. You can also use the Settings UI under Cascade to add the endpoint and refresh your active tools.

Yes, you can instruct Cascade to run `validate_context_engineering` as the first step in any multi-file editing sequence. This ensures your agent is working with prioritized, high-density context before it attempts to write code.

The validation tool returns a failure status and a detailed breakdown of the structural flaws, such as high token waste or missing semantic delimiters. Cascade will read this feedback and restructure the prompt before proceeding.

No, the server runs inside a local V8 sandbox and only processes the context metadata, token budgets, and prompt schemas you pass to it. Your actual source code and sensitive token data never leave the secure Vinkius environment.
