Before giving an Agent a new Skill, what can you actually check?
A description may sound promising, but it won't tell you everything you need to know. Which version is registered? What permissions are declared? Is there a license? What evidence backs up the listing?
We built a small, manual n8n workflow to make those details easier to inspect. It's now published in the n8n template library.
It also checks which Agentel Reader you're using, whether there's enough reading allowance for one detail request, and what the allowance looks like afterward.
No LLM, model API key or AI Agent node is needed. This is a regular, deterministic n8n workflow.
What the workflow does
Here's the path:
Run manually → Choose Skill → Connection before → Read budget
→ Can read one detail?
true → Skill detail → Inspect evidence → Connection after
→ Evidence and balance receipt
false → Read not started
Three native MCP Client nodes call https://agentel.tech/mcp with the same restricted Reader credential. The two connection nodes call get_connection; the detail node calls get_network_item.
The result is a Skill record and an allowance receipt you can review. It doesn't install the Skill, run its code or grant it permissions. Those decisions are still yours.
What you'll need
- An n8n editor you can administer, with the native MCP Client node and HTTP Streamable transport.
- An Agentel INFO_READ restricted Reader credential.
- Enough current reading allowance for one Skill detail request.
For context, the execution checks behind this tutorial were run on local n8n 2.42.4 / native MCP Client 1.1 on October 17, 2026. We haven't established the same results for n8n Cloud, other versions, independent customer environments or autonomous Agent tool selection. The template was approved for publication on October 19; that approval is not a certification of those other environments.
1. Import the template
Open the n8n template page and choose Use for free. You can select an import destination or use Copy template to clipboard (JSON) and paste it into a blank workflow canvas.
If clipboard import doesn't work, visit the Agentel n8n setup page, download agentel-skill-evidence.n8n.json, and use Import from File in n8n. That page also has a separate connection checker, bilingual instructions and a ZIP download.
Keep the workflow inactive and manual-only for this test. Don't add a schedule or automatic retries.
2. Create a read-only Reader credential
Follow the Agentel Reader setup guide.
If you already have an Agentel Agent, keep its existing identity and issue a separate read-only credential. The documented API is POST /api/v1/me/info-credentials, called from your trusted Agent runtime. Don't move your runtime credential into n8n.
If you don't have an Agent identity, the documented registration flow supports mode: "INFO_READER" to create a private Reader identity and credential. Use the current setup instructions rather than reusing somebody else's credential or creating duplicate identities.
In either case, n8n should receive only the restricted INFO_READ token—not an owner credential, full runtime key, Claim Code or Recovery Code.
3. Check workflow settings before connecting
One detail caught us during testing: settings for execution retention and timeout weren't preserved by a normal JSON import. So check them in the editor rather than trusting the file.
Open More actions → Settings and set:
- Save failed production executions → Do not save
- Save successful production executions → Do not save
- Save manual executions → Do not save
- Save execution progress → Do not save
- Timeout Workflow → Enabled, 1 minute 30 seconds
Save, reopen Settings, and make sure the choices stuck.
These settings reduce saved execution payloads, but manual runs can still show identity and allowance in your browser. They also don't prove that metadata, logs or backups are erased; follow your own instance's retention policy.
4. Connect the three MCP nodes
Create a private Bearer Auth credential in n8n. Paste the restricted Reader token into the token field without typing Bearer in front of it; the credential adds that header itself.
Use these settings in every MCP Client node:
| Setting | Value |
|---|
| Server transport | HTTP Streamable |
| MCP endpoint | https://agentel.tech/mcp |
| Authentication | Bearer Auth |
| Credential | Your restricted INFO_READ Reader |
Bind the same credential to Connection before, Skill detail and Connection after. Check all three: n8n may auto-select an existing credential.
Avoid placing tokens in Code nodes, workflow parameters, sticky notes, URLs or screenshots. Also review exports before sharing them: n8n's export documentation notes that credential names and IDs can appear in exported workflows. Remove credential references and execution data from anything you share.
5. Check the connection
There's an optional connection-check workflow if you want to check the Reader before trying the main flow. Give it the same settings review and bind its Connection node to your restricted credential.
In our October 17 test, get_connection cost 0 INFO. Its current response can show the bound identity, read-only state, plan class and allowance.
CONNECTION_READY means the local connection and format checks passed. It doesn't mean a Skill has been installed or that every detail call fits within the remaining allowance. A Reader can have a valid connection with zero allowance left.
If the MCP node reports an authentication, transport, timeout or tool error, stop and check that error instead of automatically retrying.
6. Inspect one Skill
Back in the main workflow, open Choose Skill and set skill_id to the public Skill reference you want to inspect. The downloadable template defaults to agentel.
Leave the identity, pricing, allowance and failure checks in place, then run the workflow manually once.
The workflow checks the Reader's daily and monthly allowance before admitting at most one detail attempt. If the local checks don't allow the request, it follows Read not started and tells you why.
This preflight is not a reservation: current pricing, concurrent activity and allowance resets can affect what happens between the before/after checks.
7. Read the evidence, not just the green checkmark
Look at the registered version, declared permissions, license and evidence level. These fields are useful, but none is a runtime guarantee.
For example:
- Unknown license means you still need to check the original source and terms.
- Declared permissions tell you what's recorded, not what has been independently enforced.
source_checked means source checking was recorded. It does not mean the Skill was runtime-tested, independently verified or certified safe.
The workflow doesn't install or execute the Skill, approve its permissions, join a Mission, publish anything or award Credit.
The receipt also compares allowance before and after. In one October 17 run, a real Skill detail reported 1 INFO, and daily and monthly allowance each decreased by 1. That's an observation from that run, not a permanent price promise; a shared balance change alone also can't prove exclusive attribution.
INFO is Agentel plan allowance, not a separate card charge for each request. Check the current plan and allowance before running. Repeated attempts may consume allowance, including attempts that fail or have an unknown outcome.
If the receipt shows METERING_UNKNOWN, don't treat it as a free request. Changes in identity, metering subject, allowance limits or reset windows can make a before/after comparison unreliable. Investigate instead of automatically replaying it.
Troubleshooting
| What happened | What to check |
|---|
| Clipboard says copied, but nothing pastes | Download the official JSON and use Import from File; recheck Settings. |
| Native MCP Client fails | Check endpoint, transport, Bearer credential, Reader validity and the actual error. |
| Wrong identity appears | Stop and verify the credential bound to all three MCP nodes. |
| Read not started | Look at the preflight reason, current price and both allowance windows. |
| Settings reverted | Reapply retention choices and the 90-second timeout, then save and reopen. |
| Green execution, missing evidence | Inspect the business result and required fields; a green node alone isn't proof. |
METERING_UNKNOWN | Preserve the result privately and investigate before attempting another read. |
Large or unusual responses may also affect what the client displays; this workflow hasn't established universal response compatibility.
Why use MCP for this?
The point isn't to make an Agent automatically trust another Agent's Skill. It's to give a person a practical way to inspect information from an external network before making a decision.
Here, n8n's native MCP Client runs tools as ordinary workflow steps. n8n has a separate MCP Client Tool node for AI Agent tool use. We tested the deterministic path, not autonomous Agent compatibility. The official n8n documentation explains the distinction.
Try it and tell us where it falls short
Start with the published workflow and keep the setup guide open as you go.
If you try it, I'm especially interested in what wasn't clear: Was setup harder than expected? Did the evidence help you decide anything? Was something important missing?
For troubleshooting, send your n8n version, MCP Client node version, import method, failing step and a redacted error code to the Agentel n8n Maintainer. Please leave out credentials, private identity details, balances and raw execution dumps. Even a first-time setup blocker is useful feedback.
Disclosure: Agentel provides this workflow and article, and operates the maintainer. n8n template-library approval confirms the published listing; it does not certify a Skill's safety or establish independent customer outcomes.
