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 Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- 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 Usability71
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 734 tokens (~244/item across 3 items; 3 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 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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 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 Jobs Base MCP server?
Jobs Base is a hosted endpoint at https://jobsbase.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.

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 →
get_job ~55
Get full details of a specific builder job by its ID, including description, skills, experience requirements, benefits, and company info. Use this after search_jobs to retrieve the complete listing.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | The job ID |
No output schema declared.

list_filters ~52
Get available filter values for search_jobs: job types, workplace types, cities, countries, seniority levels, and companies. Call this first to discover valid filter values before searching, especially for country codes and available cities.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
search_jobs ~627
Search and filter builder job listings on jobsbase.io — a curated board exclusively for "builder" roles (cross-functional positions where one person owns engineering, product, and delivery end-to-end: founding engineers, solo builders, 0-to-1 roles). Every job here is already an AI-native builder role, so do NOT search for generic terms like "builder", "AI", "full-stack", or "engineer" — they are redundant and will hurt results. Just use filters (country, workplace, seniority, etc.) to narrow down. Use q only for specific technologies, companies, or domain keywords. All parameters are optional.
| Name | Type | Req | Description |
|---|---|---|---|
| city | string | – | Filter by city. Comma-separated for multiple: London,Berlin |
| company | string | – | Filter by exact company name |
| country | string | – | Filter by country code. Comma-separated for multiple: US,GB,CA |
| cursor | string | – | Cursor for next page of results |
| education_level | string | – | Filter by minimum education level |
| experience_no_more_than | number | yes | Show jobs requiring no more than this many years of experience |
| limit | number | yes | Results per page (default 30, max 100) |
| posted_within | string | – | Filter by posting date: past 24h, 3d, 7d, 14d, or 30d |
| q | string | – | Optional keyword for specific technologies, domains, or companies (e.g. "React", "fintech", "Stripe"). Do NOT use generic terms like "builder", "AI", "engineer", or "developer" — every job on this bo… |
| region | string | – | Filter by geographic region. Comma-separated for multiple. Values: north_america, latin_america, europe, asia_pacific, middle_east_africa |
| salary_at_least | number | yes | Show jobs that can pay at least this amount annually (normalized to annual equivalent) |
| salary_at_most | number | yes | Show jobs that can pay at most this amount annually (normalized to annual equivalent) |
| seniority_level | string | – | Filter by seniority. Comma-separated for multiple: mid,senior. Values: internship, entry, mid, senior, lead, executive |
| sort | string | – | Sort order: relevance (best match first), posted_at (newest first, default), salary (highest salary first) |
| state | string | – | Filter by state/province name. Comma-separated for multiple: California,Texas |
| type | string | – | Filter by job type. Comma-separated for multiple: full-time,contract. Values: full-time, part-time, contract, freelance, internship |
| visa_sponsorship | boolean | yes | Set to true to only show jobs that offer visa sponsorship |
