Hermes Recall: memory tool for Hermes Agent

Engram-compatible memory provider for Hermes Agent with automatic recall and capture on every turn

What Hermes Recall does

When Engram is connected to Hermes only as an MCP server, the model decides whether to search memory and every API call carries about 19 Engram tool schemas. Hermes Recall uses the native Hermes MemoryProvider interface instead. Before every non-trivial turn Hermes runs the search, and turns with hits start with a line such as Recall, project, recalled 3 memories. Prompts, tool results, answers and subagent results are captured in the background, with a compaction archive written before context compression.

It talks to the same local Engram server as other agents, so a memory saved from Hermes appears in Pi, OpenCode or Claude Code with the same id. If no server answers, it starts engram serve itself unless ENGRAM_URL is set or autostart is off, and it refuses servers with a different instance id. The model gets compact tools such as mem_search, mem_save, mem_update, mem_context and mem_pin, about 4 KB in total. Subagents, cron jobs and memory flushes read memory but never write it.

Key features

Recall before every non-trivial turn, decided by Hermes rather than the model
Background capture of prompts, tool results, answers and subagent results
Compact memory tools including mem_search, mem_save, mem_update and mem_context
Shares memories and ids with other agents using the same Engram server
Starts a local Engram server automatically when none is running

When to use it

Making sure Hermes always checks memory before starting work
Sharing one memory store between Hermes, Pi, OpenCode and Claude Code
Replacing an Engram MCP server to cut tool schema tokens per call

Who it is for: Hermes Agent users who already use or want to use Engram as their long-term memory store.

How it fits with Hermes Agent

It is built for Hermes Agent as a memory provider plugin, activated with memory.provider set to recall rather than through plugins.enabled.
