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. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability64
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 840 tokens (~168/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage93
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 79% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
calculate_consulting_rate Calculate a consulting rate ~240
Work out what an independent consultant should charge: minimum and recommended hourly rate, day rate, monthly equivalent, and a suggested monthly retainer or project day rate. Use when someone asks what to charge, how to price a retainer, or whether their rate is too low. Ask for their income goal if you don't know it; the other inputs have sensible defaults. Returns a link that opens Retainer's free rate calculator with these numbers.
| Name | Type | Req | Description |
|---|---|---|---|
| billable_hours_per_week | number | – | Hours per week actually billed to clients, not total hours worked. Default 25. |
| expenses | number | – | Yearly business expenses (software, insurance, travel...). Default 12000. |
| margin_percent | number | – | Profit margin on top of income and expenses, as a percent. Default 20. |
| pricing_model | string | – | 'retainer' for a monthly retainer price, 'project' for a fixed-project day rate. |
| target_income | number | yes | Take-home income the consultant wants per year, in dollars. |

check_capacity Check consulting capacity ~172
Check whether an independent consultant has room for another client: available billable hours, current utilization, and whether they are under target, over target, or overcommitted. Use when someone asks if they can take on new work or feels stretched. Returns a link that opens Retainer's free capacity calculator with these numbers.
| Name | Type | Req | Description |
|---|---|---|---|
| committed_hours_per_week | number | yes | Client hours per week already committed across all current engagements. |
| non_billable_hours_per_week | number | – | Weekly hours on admin, sales, and business development that nobody pays for. Default 15. |
| target_utilization_percent | number | – | Share of billable hours they want filled, leaving a buffer for overruns. Default 80. |
| total_hours_per_week | number | – | Total hours the consultant works per week. Default 45. |

find_neglected_relationships Find neglected client relationships ~114
Check which clients, past clients, or referral sources a consultant has gone too long without talking to. Sorts contacts by days of silence into healthy (<30 days), cooling (30+), neglected (60+), and urgent (90+), with a suggested next step for each and an overall network health score. Use when someone asks who to follow up with or worries their pipeline is drying up. Returns a link that opens Retainer's free BD neglect detector with these contacts.
