What is the RE-call MCP Memory Server MCP server?

Agent memory on your own Postgres that flags superseded facts and abstains instead of guessing.

How to install RE-call MCP Memory Server

Copy-paste configuration for popular MCP clients.

transport: stdio

Config generated by PluginBench — verify against the source before use.

Environment / auth

RECALL_SERVING_DSN
required
secret
PostgreSQL serving DSN for the RE-call memory store.
RECALL_TENANT
Tenant id served by this local stdio server.
RECALL_TRUST_MODE
Set to development only for local uncalibrated corpora.
RECALL_EMBEDDER
The embedder the corpus was BUILT with, for example voyage:voyage-4 or BAAI/bge-large-en-v1.5. It must match: several models emit 1024 dimensions, so a mismatch does not error, it returns a confidently ranked list that means nothing.
RECALL_TABLE
The chunk table inside that database. `recall quickstart` indexes into quickstart_chunks so its sample corpus can never be retrieved beside real memory; `recall setup` uses chunks. The wrong value returns no hits and no error.
RECALL_MCP_TOOLS
Optional. Serve a subset of the tools: a preset (all, search, read) or explicit names. Every tool definition is re-sent every turn, so serving ones nobody calls costs input tokens on every turn. Unset serves them all.
