OP.GG MCP Server

Local daemon that tracks Claude Code and OpenCode sessions in real-time. Exposes an MCP server so Claude can query its own usage mid-session: quota status, session cost, top tools, weekly insights, burn rate, and model breakdown. No cloud, no accounts — everythin stays on disk.

62(and growing) read-only diagnostic tools that let Claude inspect your Linux fleet without touching it. Files, systemd, performance, networking, processes, disks, kernel, packages, Docker — each a hardened wrapper around a command you already trust, run over your own SSH config. Read-only by construction: there is no code path that restarts a service, edits a file, installs a package, or runs anything that mutates state. Every argument is validated and shell-quoted, flag injection is killed by per-tool whitelists, and hosts can be pinned to an allowlist. Point it at production and sleep. Run any tool on one host, or pass a list to fan out in parallel — bounded, with a hard 25-host ceiling so a curious model can't trigger an SSH storm. Why - Can't break anything — no mutate path exists. No restart, no edit, no install, no -exec. - Injection-hardened — shlex.quote everywhere, flag whitelists, NUL/newline rejection, host allowlist. - Your SSH, your rules — uses your ssh/agent or any wrapper (tsh ssh, jump hosts). Server never sees a credential. - Bounded — byte-capped output, per-call timeouts, capped multi-host fan-out. - Auditable — structured {stdout, stderr, exit_code, truncated} + optional JSONL logs with per-call IDs. Setup Python via uv. One mcpServers entry, tuned by env vars. Works with Claude Desktop and Claude Code.

mcp-kinetic-gain is a single stdio MCP server that exposes all eleven Kinetic Gain Protocol Suite specs to any MCP-compatible client (Claude Desktop, Cline, Cursor, etc.) — 71 tools across AEO Protocol, Prompt Provenance, Agent Cards, AI Evidence Format, MCP Tool Cards, AI Tutor Cards, Student AI Disclosure, Classroom AI AUP, Clinical AI Disclosure, AI Incident Card, AI Procurement Decision Card, plus the DefenseTech 6-pack tooling shipped in v0.8.0. Includes ed25519 attestation verification, hash-chained audit-stream event composition and chain verification (offline AND live against a running audit-stream-py via the optional AUDIT_STREAM_URL env var), cross-spec drift detection, and a Decision Intelligence preview that generates a PolicyBundle from a Decision Card, infers rubric status, and plans incident remediation. Also doubles as a CLI: `npx mcp-kinetic-gain validate path/to/doc.json` auto-detects which Suite spec a JSON file belongs to and validates it against the same zod schemas the MCP tools use. No API key. No build step. Headline tools: aup_check_compliance, decision_card_validate, decision_card_to_policy_bundle, attestation_verify, suite_doc_drift, audit_chain_verify, audit_event_emit, audit_events_query, audit_chain_verify_live.
