Lightrun

Lightrun MCP connects AI coding assistants to live runtime context from production and staging applications.

Quick Start

# Connect this server (installs CLI if needed)
npx -y smithery mcp add roib/lightrun

# Browse available tools
npx -y smithery tool list roib/lightrun

# Get full schema for a tool
npx -y smithery tool get roib/lightrun get_runtime_callstack

# Call a tool
npx -y smithery tool call roib/lightrun get_runtime_callstack '{}'

Direct MCP Connection

Tools (8)

• get_runtime_callstack — Capture the runtime call-stack at a specific code location in a real-time, runtime environment, using Lightrun Snapshot…
• get_runtime_numeric_metric — Sample the value of a code expression every time the indicated code line executes.
• get_runtime_numeric_metric_samples — Fetch raw custom-metric measurement samples for a specific agent from a prior custom-metric run.
• get_runtime_execution_count — Count how many times a specific code line executes in a live application during a sampling window, and return per-agent…
• get_runtime_execution_duration — Measure execution duration of a specific code section in a live application using Lightrun TicToc,
• get_runtime_execution_duration_samples — Fetch raw execution-duration measurement samples for a specific agent from a prior execution-duration run.
• get_runtime_expression_values — Capture runtime expression values at a specific code location in a live application
• get_runtime_sources — Discover available Lightrun sources on which Lightrun MCP tools can be used in order to capture runtime data.
