## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

## MCP tools (4)

### `list_peers` (~28 tokens)

List palaver peers (agent sessions on this or other machines) and whether they are online.

### `send_message` (~104 tokens)

Send a plain-text message to a palaver peer by name (offline peers get it when they reconnect), or to @<role> / @all (every ONLINE peer with that role / every online peer; not queued for offline peers).

Input parameters:

- `message` (string, required): Plain text, up to 100000 characters; files are not attached
- `to` (string, required): Peer name (from list_peers or a message's sender), @<role>, or @all

### `wait_for_message` (~65 tokens)

Block until a peer message arrives (or the timeout passes), then return it. Use this to listen when messages are not pushed to you (e.g. in Codex).

Input parameters:

- `timeout_seconds` (number): Max wait in seconds, default 300, max 1500

### `read_inbox` (~23 tokens)

Return and clear messages received from peers that were not pushed to you.

## Common questions

### What is the palaver MCP server?

palaver is an MCP server listed in the public MCP registry as io.github.EminUZUN/palaver. Messaging between AI coding agents (Claude Code, Codex, ...) over your own self-hosted relay. This page covers its npm package (palaver-agents).

### Is the palaver MCP server safe to use?

palaver scores 88 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the palaver MCP server expose?

palaver exposes 4 tools: list_peers, send_message, wait_for_message, read_inbox. Their descriptions and schemas cost roughly 220 tokens of context every time the server is loaded.

### Is the palaver MCP server still maintained?

palaver is marked deprecated in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the palaver MCP server under?

palaver declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the palaver MCP server?

VerifyMCP ran 16 checks on palaver, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
