Mercury Connector for Muse

Prerequisites: A Mercury API token (app.mercury.com > Settings > API Tokens — a Read-Only token suffices, no IP whitelist needed), kept in your Muse's secure vault (never paste secrets here). Note: this connector is read-only by design — it cannot move money; Mercury banking is free for eligible US companies. No GitHub account needed unless listed here. Install "Mercury Connector for Muse" for me. A Muse agent skill with read-only access to your Mercury banking: list bank accounts, view recent transactions per account. Repository: https://github.com/bluman1/muse-connectors/tree/main/connectors/mercury 1. Fetch the SKILL.md file (and any helper files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "mercury". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. save my Mercury API token in the vault). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
