It sits in Documents & Office, covering MCP servers and Excel spreadsheets. It works with Model Context Protocol and Microsoft Excel. The repository describes itself as: Experimental Excel sidebar agent add-in. Multi-model. Powered by Pi. The licence is MIT.
When your agent uses it
- External capabilities are needed beyond built-in workbook tools
- Tasks that involve MCP servers
- Tasks that involve Excel spreadsheets
Example prompts
- “/mcp-gateway”
Requirements
- Compatibility (from SKILL.md): Requires Pi for Excel integration "mcp_tools" to be enabled and at least one MCP server configured.
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Open /tools (or /extensions → Connections tab).
- Enable external tools.
- Add one or more MCP servers.
- Enable MCP Gateway for session and/or workbook scope.
What it can do on your machine
Read from SKILL.md and the folder at commit a3cea8f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Requires Pi for Excel integration "mcp_tools" to be enabled and at least one MCP server configured.
From compatibility in the SKILL.md frontmatter.
Context cost
MCP Gateway loads about 241 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 79 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
