Agent integration
Hosted MCP bridge Starter skills Workspace API keys

Connect agents without building the glue yourself.

Every workspace gets a hosted memory surface for recall, remember, recent history, and higher-level Engram tools. The integration path stays simple: issue a workspace key, hit bootstrap, and start calling the service.

Read docs Connect guide Create workspace
Bootstrap

One request returns the API surface, bridge URL, and skill download paths.

Bridge

66 hosted tool calls when the agent cannot run a local MCP server.

Skills

Starter markdown skills drop directly into Codex or Claude-style workflows.

key bootstrap tools skills
01 / Key
Issue access

Create one workspace key per agent so usage and revocation stay understandable.

02 / Bootstrap
Load service shape

Fetch URLs, auth shape, starter skills, and bridge metadata before the agent starts.

03 / Tools
Call memory tools

Use the hosted bridge for recall, project state, decisions, checkpoints, and curation.

04 / Skills
Teach the workflow

Install the starter skill so agents know when to recall and when to write handoffs.

Bootstrap endpoint Workspace-specific service URLs and integration metadata in one response
Bridge tools Focused hosted access to selected Engram methods over HTTP JSON
Skill downloads Plain markdown starter skills for fast memory/handoff setup

Integration recipes

Short paths for common agent and service wiring.

Codex-style handoff

Load bootstrap Recall recent context Work normally Remember outcome
curl -H "Authorization: Bearer $MEMORYLAYER_KEY" "$MEMORYLAYER_URL/api/workspaces/$SLUG/bootstrap"

Hosted MCP bridge

List bridge tools POST tool name and args Store audit trail
curl -X POST -H "Authorization: Bearer $MEMORYLAYER_KEY" -H "Content-Type: application/json" -d '{"tool":"recall_recent","args":{"limit":5}}' "$MEMORYLAYER_URL/api/workspaces/$SLUG/mcp"

Ingestion pipeline

Create a service key POST memories Watch usage events
curl -X POST -H "Authorization: Bearer $MEMORYLAYER_KEY" -H "Content-Type: application/json" -d '{"source_name":"handoff.md","items":["Deployment completed","Follow up on billing UI"],"layer":"episodic","memory_type":"fact"}' "$MEMORYLAYER_URL/api/workspaces/$SLUG/ingest"

Usage monitor

Poll usage endpoint Group by route Rotate quiet or noisy keys
curl -H "Authorization: Bearer $MEMORYLAYER_KEY" "$MEMORYLAYER_URL/api/workspaces/$SLUG/usage"

Compact prompt context

Call MCP bridge Fetch recall_context Inject result
curl -X POST -H "Authorization: Bearer $MEMORYLAYER_KEY" -H "Content-Type: application/json" -d '{"tool":"recall_context","args":{"query":"current project state","max_tokens":1200}}' "$MEMORYLAYER_URL/api/workspaces/$SLUG/mcp"

Session checkpoint

Summarize work Save checkpoint Resume later
curl -X POST -H "Authorization: Bearer $MEMORYLAYER_KEY" -H "Content-Type: application/json" -d '{"tool":"session_checkpoint","args":{"note":"Finished deploy; next check onboarding flow","limit":8}}' "$MEMORYLAYER_URL/api/workspaces/$SLUG/mcp"

Negative knowledge

Catch bad assumption Store exclusion Prevent repeat
curl -X POST -H "Authorization: Bearer $MEMORYLAYER_KEY" -H "Content-Type: application/json" -d '{"tool":"remember_negative","args":{"content":"Do not use local SQLite for production memory","scope":"deployment","context":"Postgres is required for hosted workspaces"}}' "$MEMORYLAYER_URL/api/workspaces/$SLUG/mcp"

Entity pivot

Find entity Load graph Follow related work
curl -X POST -H "Authorization: Bearer $MEMORYLAYER_KEY" -H "Content-Type: application/json" -d '{"tool":"entity_graph","args":{"name":"Memorylayer"}}' "$MEMORYLAYER_URL/api/workspaces/$SLUG/mcp"

Curation pass

Find duplicate cluster Deduplicate Check quality
curl -X POST -H "Authorization: Bearer $MEMORYLAYER_KEY" -H "Content-Type: application/json" -d '{"tool":"dedup","args":{"threshold":0.92,"max_merges":5}}' "$MEMORYLAYER_URL/api/workspaces/$SLUG/mcp"

Tool manifest

Fetch manifest Group tools Render client UI
curl "$MEMORYLAYER_URL/api/mcp/manifest"

Public capability sync

Fetch capabilities Cache counts Expose service map
curl "$MEMORYLAYER_URL/api/capabilities"

Workspace health check

Call health Read memory map Export recent
curl -X POST -H "Authorization: Bearer $MEMORYLAYER_KEY" -H "Content-Type: application/json" -d '{"tool":"health","args":{}}' "$MEMORYLAYER_URL/api/workspaces/$SLUG/mcp"
