Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00021 | $0.00301 |
| Opus 5.5 | $0.00008 | $0.00120 |
| Sonnet 5.5 | $0.00004 | $0.00060 |
| Haiku 4.5 | $0.00002 | $0.00030 |
Grade B, and why
onboard scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Reads MCP configurationmediumAgent snooping
mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.
2. If tools are missing, inspect the generated `.mcp.json`. In the recommended stdio mode, confirm it points to `scripts/mem0_oss_stdio_bridge.py` and that `MEM0_OSS_ENV_FILE` exists. In direct HTTP mode, explain that th What it actually says
Mem0 OSS Onboarding
Use this when the user asks to set up or verify Mem0 OSS in Codex.
- Confirm MCP tools are visible. Search tool names for
mem0and verifyadd_memory,search_memories, andget_memoriesare exposed. - If tools are missing, inspect the generated
.mcp.json. In the recommended stdio mode, confirm it points toscripts/mem0_oss_stdio_bridge.pyand thatMEM0_OSS_ENV_FILEexists. In direct HTTP mode, explain that the token env var named by the generated plugin must be present in the Codex process environment, then start a new thread. - Run a read check with
search_memoriesusingquery="health check"and filters for the activeuser_idandapp_id. - Run a write check only with user approval: add a short
health_checkmemory, read event status if available, then delete the probe memory if the bridge returns an id. - Confirm hooks only if
~/.codex/hooks.jsoncontains commands for this generated plugin and[features].codex_hooks = trueis set.
Never print token values. For generated Mem0 OSS plugins, the token is a local bridge bearer token, not a Mem0 Platform API key.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

onboard is a skill published in the GitHub repository SteinX/mem0-oss-mcp (0 stars, last pushed 8d ago), licensed MIT. It adds 21 tokens to every session and 301 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads mcp configuration). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
