AST Parsing for Windsurf Cascade

The `evaluate_math` tool gives Cascade a deterministic engine for processing algebraic expressions. When your agent encounters complex math, it routes the string directly to this strict AST parser instead of trying to guess the answer. You get exact calculations without the hallucination risks common in large language models. Standard IDE setups often force agents to write Python scripts just to calculate a formula. This MCP server skips that entire overhead. Cascade simply passes the equation string and receives the evaluated result instantly, keeping the autonomous chain moving without dropping context.

Zero Code Execution Risk

The `evaluate_math` tool operates entirely without `eval()` calls. This MCP server blocks remote code execution vulnerabilities at the source. If Cascade accidentally formats a command injection attempt as a math problem, the parser outright rejects it. You need this isolation when working with untrusted inputs or complex financial models. The parser restricts operations to basic arithmetic, parentheses, and standard order of operations. It guarantees that mathematical evaluation never escapes into your host environment.

Unbroken Autonomous Chains

The `evaluate_math` tool ensures Cascade never stalls on arithmetic errors during multi-step tasks. Language models struggle with nested parentheses and floating-point logic. By offloading these calculations, your agent maintains accuracy across long operational sequences. You set the goal, and Windsurf figures out the steps. When one of those steps requires crunching numbers for a layout calculation or data transformation, the math engine handles it silently in the background. The agent gets the exact integer or float it needs to write the next block of code.

Setup guide

Set up Deterministic Math Expression Evaluator 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 Deterministic Math Expression Evaluator 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 Deterministic Math Expression Evaluator payment history." If connected, Cascade will call the Deterministic Math Expression Evaluator tools directly. You will see a green dot next to the server name in the MCP panel.

Common questions about Deterministic Math Expression Evaluator MCP in Windsurf

Open your `~/.codeium/windsurf/mcp_config.json` file. Add the server details under the `mcpServers` object. You can also use the Settings -> Cascade -> MCP Servers UI and hit Refresh to load the tools.

Spinning up a Python environment for basic algebra introduces latency and potential security risks if you use `eval()`. This MCP server uses an AST parser that evaluates strings in under a millisecond. It keeps Cascade moving fast without exposing your machine to arbitrary code execution.

No. The parser strictly handles basic arithmetic, algebraic order of operations, and parentheses. It intentionally excludes arbitrary symbolic calculus or dynamic programming to maintain a tight security boundary.

Cascade auto-discovers the tool schema upon connection. When your prompt requires numerical accuracy, the agent automatically structures the equation and calls the tool before proceeding with code generation.

The server only processes the specific mathematical string expressions passed to it by the agent. It has zero access to your local file system, project code, or environment variables. All parsing happens in an isolated V8 sandbox and vanishes immediately after returning the result.
