monarch-money-mcp-server@0.0.13
VERIFIEDPublisher claims: "MCP server for Monarch Money — account, transaction, and budget management." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Server started and answered tools/list.- Tested
- MCP initialize and tools/list · every tool description, for hidden instructions · every file read, file written and host contacted by what ran
- Not tested
- what the tools do when called with real credentials
Before you give it your token
- It will ask for
MONARCH_PASSWORDMONARCH_SESSION_TOKENConfiguration, not credentials: MONARCH_DISABLED_TOOLS, MONARCH_EMAIL, MONARCH_EMAIL_OTP, MONARCH_ENABLED_TOOL_GROUPS, MONARCH_ENABLED_TOOLS, MONARCH_SESSION_PASSPHRASE, MONARCH_STATE_DIR, MONARCH_TOTP- Where it talks to
- no vendor host named in the codeAlso monarch.com — not the publisher's domain; check what for before connecting.
- What the honeypot saw
- no credential files read · no network
- What we could not test
- what the tools do when called with real credentials
Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names monarch.com as well as its own vendor. The guard injects MONARCH_PASSWORD, MONARCH_SESSION_TOKEN only into requests to the host you bind (and its subdomains) and refuses the rest.
Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-11-13 and scored it 86/100 (Verified). It did what it claims and nothing else we could detect: no undeclared network egress, no credential reads, no persistent instruction writes. Summary: no network, touches nothing outside the project, writes no memory.
