## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but the endpoint returned HTTP 404.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Capabilities**: 0/100
  - Capabilities not yet verified: we couldn't read the endpoint's capabilities.

**Unverified: 5 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## MCP tools (6)

### `calc_reconstitution` (~244 tokens)

Peptide reconstitution calculator

Calculate peptide reconstitution: concentration, draw volume, syringe units and doses per vial. Forward mode: dose_mcg. Reverse mode: pass dose_units to back-solve the dose. Returns precision (parallax) warnings, syringe overflow checks and concentration advisories. Research use only.

Input parameters:

- `dose_mcg` (number): Target dose in mcg (forward mode).
- `dose_units` (number): Syringe units drawn (reverse mode; back-solves the dose).
- `lang` (string): Language for human-readable fields.
- `peptide` (string): Peptide id or name (e.g. "bpc-157"). Optional context provider; use list_peptides to discover.
- `syringe_capacity_ml` (number): Barrel capacity in ml. Common: 0.3, 0.5, 1.
- `syringe_type` (string): Syringe grading: U-100 (1 ml = 100 units) or U-40 (1 ml = 40 units).
- `vial_mg` (number, required): Peptide amount in the vial, mg.
- `water_ml` (number, required): Bacteriostatic water added, ml.

### `list_peptides` (~62 tokens)

List research peptides

List or search the curated research peptide dataset (ids, names, aliases, categories, confidence grades, common dosing windows). Research use only.

Input parameters:

- `lang` (string)
- `query` (string): Optional search: id, name, alias or category fragment.

### `get_protocol` (~73 tokens)

Get research protocol

Get the full research protocol record for one peptide: dosing window, frequency, cycle, titration ladder (GLP-1 class), special notes and confidence grade. Research use only.

Input parameters:

- `lang` (string)
- `peptide` (string, required): Peptide id or name, e.g. "semaglutide".

### `plan_schedule` (~195 tokens)

Plan titration schedule

Generate a week-by-week research schedule: frequency presets (daily / 1-3x weekly), GLP-1 style titration ladders and optional syringe-unit readouts per event. On-demand compounds return an advisory instead of a calendar. Research use only.

Input parameters:

- `days` (array): 0=Mon … 6=Sun; count must match the frequency (daily=7, 1x=1, 2x=2, 3x=3).
- `lang` (string)
- `peptide` (string, required): Peptide id or name.
- `start_date` (string): First day of week 1, YYYY-MM-DD (defaults to today, UTC).
- `vial_mg` (number): With water_ml: adds per-event syringe units.
- `water_ml` (number): With vial_mg: adds per-event syringe units.
- `weeks` (integer): Schedule length in weeks.

### `plan_stack` (~132 tokens)

Plan a compound stack

Plan a multi-compound stack: per-compound draw volumes and units, combined draw volume with split-injection advisories, and frequency-conflict detection. Research use only.

Input parameters:

- `entries` (array, required): 2–4 compounds in the stack.
- `lang` (string): Language for human-readable fields.
- `syringe_capacity_ml` (number): Barrel capacity in ml. Common: 0.3, 0.5, 1.
- `syringe_type` (string): Syringe grading: U-100 (1 ml = 100 units) or U-40 (1 ml = 40 units).

### `compare_syringes` (~88 tokens)

Compare syringes

Compare U-100 and U-40 syringes for one target dose: units required, fit and relative reading error (parallax risk). Sorted best-first. Research use only.

Input parameters:

- `dose_mcg` (number, required)
- `lang` (string)
- `peptide` (string)
- `vial_mg` (number, required)
- `water_ml` (number, required)

## Common questions

### What is the PeptideLab Calculator MCP server?

PeptideLab Calculator is an MCP server listed in the public MCP registry as com.rigorpeptides/peptidelab. Research-use peptide reconstitution & dosing calculators for 15 compounds. Not medical advice. This page covers its hosted endpoint (https://rigorpeptides.com/mcp).

### Is the PeptideLab Calculator MCP server safe to use?

PeptideLab Calculator scores 23 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 PeptideLab Calculator MCP server expose?

PeptideLab Calculator exposes 6 tools: calc_reconstitution, list_peptides, get_protocol, plan_schedule, plan_stack, compare_syringes. Their descriptions and schemas cost roughly 794 tokens of context every time the server is loaded.

### Does the PeptideLab Calculator MCP server require authentication?

Its publisher declares no required credentials for PeptideLab Calculator. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

### Is the PeptideLab Calculator MCP server still maintained?

PeptideLab Calculator 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 PeptideLab Calculator MCP server?

VerifyMCP ran 5 checks on PeptideLab Calculator, covering TLS certificate, HTTPS, HSTS header, DNSSEC and 1 more. 6 items could not be completed, a gap on our side rather than a finding about PeptideLab Calculator: Authorization, Schema quality, Stability, Tool coverage and 2 more. 5 categories score 0 for that reason, because we only credit what we can confirm. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
