mcp-analytics skillA

mcp-analytics is agent-read markdown (skill) from jsonbored/metagraphed: Add PostHog MCP analytics to a TypeScript, JavaScript, or Python MCP server. Instruments the server so every tool call, agent intent, and failure is captured as a $mcp_* event — the @posthog/mcp Node SDK for TS/JS, or posthog.mcp (shipped inside the posthog package) for Python. Detects the server style (official MCP SDK Server/McpServer/FastMCP, mcp-handler, @rekog/mcp-nest, jlowin fastmcp, or a custom HTTP/edge dispatcher) and wires in the matching instrumentation, credentials, and graceful shu.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add jsonbored/metagraphed/mcp-analytics@v1.34.0
Exact content
mdr add jsonbored/metagraphed/mcp-analytics@sha256:f489809284490db6

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
