## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 0/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
  - Install-script risk not yet assessed.
  - Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
- **Provenance & Transparency**: 32/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: no license is declared.
  - Actively maintained (last published 2 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 79/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 437 tokens (~87/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 73/100
  - Stability observed for 22 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (5)

### `get_traces` (~139 tokens)

List this team's traces newest-first with filters, as the JSON document `simpletel get traces --format json` produces. Use it to find a failing or slow request, then pass the trace_id to get_trace.

Input parameters:

- `errors_only` (boolean): only traces with at least one error span
- `limit` (integer): maximum number of traces to return
- `min_duration` (string): minimum trace duration such as "250ms"
- `service` (string): exact match on the root span's service.name
- `since` (string): lookback window such as "1h" or "30m" (default "1h")

### `get_trace` (~63 tokens)

Fetch one trace in full — spans, span events, and correlated log records — as the JSON document `simpletel get trace <id> --format json` produces.

Input parameters:

- `trace_id` (string, required): 32-hex trace id, as returned by get_traces

### `get_signals` (~99 tokens)

Show this team's Golden Signals over a window — throughput, error rate, latency percentiles, per-service breakdown, and saturation — as the JSON document `GET /api/v1/signals` produces.

Input parameters:

- `service` (string): exact match on the resource service.name (omit for all services)
- `since` (string): lookback window such as "1h" or "30m" (default: the server's 1h window)

### `verify` (~99 tokens)

Run the `simpletel verify` onboarding check: poll until service <service> has a fresh trace carrying spans from a library instrumentation. Returns the rung report and the exit status the CLI would use (0 verified, 1 deadline miss).

Input parameters:

- `service` (string, required): service.name expected to be sending fresh, library-instrumented traces
- `timeout` (string): give up after this long, such as "60s" (default "60s")

### `usage` (~37 tokens)

Show the account's plan, month-to-date records, allowance, and spend cap as the JSON document `simpletel usage --format json` produces.

## Common questions

### What is the simpletel MCP server?

simpletel is an MCP server listed in the public MCP registry as io.github.willnewby/simpletel. Query your simpletel OpenTelemetry traces and account usage from a coding agent. This page covers its container image (ghcr.io/willnewby/simpletel-mcp).

### Is the simpletel MCP server safe to use?

simpletel scores 47 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the simpletel MCP server expose?

simpletel exposes 5 tools: get_traces, get_trace, get_signals, verify, usage. Their descriptions and schemas cost roughly 437 tokens of context every time the server is loaded.

### Is the simpletel MCP server still maintained?

simpletel is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the simpletel MCP server?

VerifyMCP ran 12 checks on simpletel, covering Source repository, Provenance, License, Maintenance and 8 more. 4 items could not be completed, a gap on our side rather than a finding about simpletel: Malware scan, Known CVEs, Install scripts and Dependency health. One category scores 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to a container image, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
