Physbound tools (6)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • antenna_gain

    Calculate antenna aperture gain limits, beamwidth, far-field distance; validate gain claims.

  • noise_floor

    Calculate thermal noise power (kTB), cascaded noise figure, and receiver sensitivity.

  • radar_ambiguity

    Calculate pulse-Doppler radar ambiguity limits and validate range/velocity claims.

  • radar_range

    Calculate maximum monostatic radar detection range and validate range claims.

  • rf_link_budget

    Calculate a complete RF link budget using the Friis transmission equation.

  • shannon_hartley

PhysBound

Physical Layer Linter — an MCP server that validates RF and physics calculations against hard physical limits, catching AI hallucinations in engineering workflows.

LLMs generate plausible-sounding RF numbers that violate fundamental physics — throughput above the Shannon limit, antenna gains no aperture can produce, radar ranges the range equation forbids. PhysBound gives any MCP-compatible AI assistant six validated calculation tools, backed by CODATA constants (via SciPy) and dimensional analysis (via Pint). Impossible claims return structured PhysicalViolationError responses with the violated law, the computed limit, and a LaTeX explanation — not silent failures.

Installation

PhysBound is a standard stdio MCP server published on PyPI. The recommended launch command is uvx physbound, which fetches and runs the latest release in an isolated environment — no manual install step.

First run: uvx downloads ~60 MB of dependencies (SciPy, NumPy) the first time. Run uvx physbound once in a terminal to pre-cache them (Ctrl-C to exit); subsequent starts are instant.

Physbound: common questions

Is Physbound MCP server safe?
Yes, by our scan: it is graded A (92/100). Read the Physbound safety report
How do I install Physbound?
It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
Does Physbound need an API key?
Not as far as the registry entry and our scan can tell: no credentials are declared or required.
Is Physbound maintained?
The last commit was 10 days ago (2026-10-26). The latest release is v0.3.0.
What can I use instead of Physbound?
Servers from other publishers that do the same job: Oh My Posh Validator MCP server.
How does Physbound compare with other MCP servers?
safety score 92/100 (higher than 93% of 48,243 servers); tools 6 (the typical server has 7); tools that change things 0% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
