Available components
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 Security74
- 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
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability86
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1027 tokens (~114/item across 9 items; 6 tools + 3 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 Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the io.github.Bluecraft-AI/machfive MCP server?
io.github.Bluecraft-AI/machfive is a hosted endpoint at https://mcp.machfive.io/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

No change was recorded against any check on this day. Stability & Change Management went from 93 to 97. That category is still filling its 30-day observation window: 28 days of observed history at the previous scan, 29 at this one. The score rises as the window fills, whether or not the server changes.

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 →
export_list Export List ~90
Download the generated email sequences for a COMPLETED list. Only call this AFTER get_list_status shows processing_status = 'completed'. If the list is not yet completed, you'll get a 409 error — poll first.
| Name | Type | Req | Description |
|---|---|---|---|
| format | string | – | Output format: 'json' (structured data) or 'csv' (raw CSV for sending tools). |
| list_id | string | yes | List UUID to export. |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
generate_batch Generate Batch ~236
Submit multiple leads for batch email sequence generation (ASYNC). Returns IMMEDIATELY with a list_id. Processing runs in the background. After calling this, poll get_list_status every 15-30 seconds until processing_status is 'completed' or 'failed', then call export_list. You must have a campaign_id first. Call list_campaigns if you don't have one.
| Name | Type | Req | Description |
|---|---|---|---|
| approved_ctas | string | – | Comma-separated CTAs. Omit to use campaign defaults. |
| campaign_angle | string | – | Additional context/angle for personalization. |
| campaign_id | string | yes | Campaign UUID from list_campaigns. |
| email_count | integer | – | Number of emails per lead, 1-5. |
| email_signature | string | – | Signature appended to each email. |
| leads_json | string | yes | JSON array of lead objects. Each MUST have "email". Optional: name, title, company, company_website, linkedin_url. Example: '[{"email":"jane@acme.com","name":"Jane Doe"}]' |
| list_name | string | – | Display name for this batch in MachFive UI. |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
generate_sequence Generate Email Sequence ~302
Generate a personalized cold email sequence for ONE lead. This is SYNCHRONOUS — the request takes 3-10 minutes because MachFive researches the prospect and crafts unique emails. Do NOT retry if it seems slow; wait for the response. You must have a campaign_id first. Call list_campaigns if you don't have one. If the request times out, use the returned list_id with get_list_status and export_list to recover results.
| Name | Type | Req | Description |
|---|---|---|---|
| approved_ctas | string | – | Comma-separated CTAs, e.g. 'Direct Meeting CTA, Lead Magnet CTA'. Omit to use campaign defaults. |
| campaign_angle | string | – | Additional context/angle for personalization. |
| campaign_id | string | yes | Campaign UUID from list_campaigns. |
| company | string | – | Lead's company name (improves personalization). |
| company_website | string | – | Company URL for AI research. |
| string | yes | Lead's email address (REQUIRED). | |
| email_count | integer | – | Number of emails in sequence, 1-5. |
| email_signature | string | – | Signature appended to each email. |
| linkedin_url | string | – | LinkedIn profile URL for deeper personalization. |
| list_name | string | – | Display name for this list in MachFive UI. |

No examples provided.
get_list_status Get List Status ~79
Check the processing status of a lead list. Use this to POLL after calling generate_batch. Call every 15-30 seconds until processing_status is 'completed' or 'failed'. When completed, call export_list. When failed, submit a new batch.
| Name | Type | Req | Description |
|---|---|---|---|
| list_id | string | yes | List UUID from generate_batch or generate_sequence response. |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
list_campaigns List Campaigns ~108
List campaigns in the user's MachFive workspace. CALL THIS FIRST before generate_sequence or generate_batch — you need a campaign ID to generate emails. If the user hasn't specified a campaign, call this and ask them to pick one. Returns JSON array of campaigns with id, name, and created_at. Use the 'id' field as campaign_id in generate calls.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | – | Search string to filter campaigns by name (case-insensitive substring match). Leave empty to list all. |
