CtxWise: MCP schema tree-shaker and context firewall

Local-first Apache-2.0 CLI for Claude Code/Codex/Cursor: mcp-xray ranks bloated tool schemas, sync compresses CLAUDE.md↔AGENTS.md↔Cursor rules, and shield fails CI on leaked keys/prompt-injection/Trojan Unicode—claims large cuts in model-visible prompt size without API calls.

Speko MCP: build and operate voice agents from the coding agent

Hosted Speko MCP (mcp.speko.ai, 101 tools) lets Claude Code/Codex/Cursor create, deploy, roll back and eval voice agents, manage sessions/calls/phone numbers/knowledge bases, and migrate external configs—directory hosts expose narrower, safer tool surfaces.

Octopus remote MCP: deploy/operate without a local install

Octopus Cloud ships a built-in HTTP MCP at /mcp so coding agents can list spaces/projects, check PR deployment status, create/promote releases, run runbooks, search task logs and audit events—no per-machine local MCP to install; Server gets it in 2026.3.
