reddit-mcp-buddy@1.2.1
VERIFIEDPublisher claims: "Clean, LLM-optimized Reddit MCP server: browse, search, and analyze Reddit, with opt-in posting and commenting behind server-side safety rails." 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
REDDIT_CLIENT_SECRETREDDIT_PASSWORDREDDIT_REFRESH_TOKENor--oauthConfiguration, not credentials: REDDIT_BUDDY_ALLOWED_HOSTS, REDDIT_BUDDY_ALLOWED_ORIGINS, REDDIT_BUDDY_HOST, REDDIT_BUDDY_HTTP, REDDIT_BUDDY_NO_CACHE, REDDIT_BUDDY_PORT, REDDIT_BUDDY_WRITE, REDDIT_CLIENT_ID, REDDIT_USER_AGENT, REDDIT_USERNAME- Where it talks to
- no vendor host named in the codeAlso reddit.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 reddit.com as well as its own vendor. The guard injects REDDIT_CLIENT_SECRET, REDDIT_PASSWORD, REDDIT_REFRESH_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 2026-11-11 and scored it 83/100 (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.

Tokens estimated at four characters each. The tool list is re-read by the agent on every turn, so it is the number to compare between servers that do the same job: ranked across the index.
