Mathematical Code Execution
ai.saifsPublished by saifs.aiOfficial publisherv1.0.1Updated Oct 30, 2026
Run sandboxed Python for calculations and PDFs; no other languages, installs or network.
The publisher's own server: Customer Intelligence & Segmentation
Overview
Remote MCP server that runs allow-listed Python in a sandbox so an assistant can compute results or produce a one-page PDF.
- What you can do
- Run Python snippets and get back stdout, stderr and exit code
- Compute with numpy for calculations such as means, standard deviations and matrix products
- Generate a one-page PDF with the preinstalled fpdf library and receive a temporary download link
- Reject non-Python code with a one-line warning
- When to use it
- Useful when an assistant needs to actually execute arithmetic, statistics or numpy work instead of estimating, or to hand back a small generated PDF such as an invoice summary. It is not meant for other languages, package installs, network access or reading user files.
- Requirements
- Remote Streamable HTTP endpoint; nothing to install locally. OAuth 2.1 sign-in (PKCE with dynamic client registration) is required, and the client opens a sign-in page on first use. Configure the endpoint URL in an MCP-capable client such as VS Code, Claude or Claude Code.
Installation
In SourceWeft
- Open Mathematical Code Execution in the dashboard and add it to a workspace.
- Connect the required credentials. They are stored privately and never shown on public pages.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/ai.saifs%2Fcode-execution/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Other MCP clients
Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Mathematical Code Execution
A Python-only sandbox for agent hosts. The model writes Python that prints a result (or a one-page PDF via preinstalled fpdf); this server runs it in an isolated process with no network, no user filesystem and no package installs. Other languages are refused. numpy is available; scipy and pandas are not.
Install
VS Code / GitHub Copilot
Add to .vscode/mcp.json (workspace) or your user mcp.json:
Then start the server from the MCP view and sign in when prompted.
Claude (claude.ai, Desktop)
Settings → Connectors → Add custom connector, and paste:
Claude Code
Any other MCP client
Point it at https://code-execution-mcp.saifs.ai/mcp using the Streamable HTTP transport. The server returns 401 with a
WWW-Authenticate: Bearer … resource_metadata=… challenge, so OAuth-aware clients sign in automatically.
Tools
Example prompts
- “Run Python to compute the mean and standard deviation of this list and print the result.”
- “Write a short numpy snippet that multiplies these two matrices and prints the product.”
- “Generate a one-page PDF invoice summary with fpdf and give me the download link.”
