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 Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (zambo_universal). See how to fix → View diagnostics → Fail
- 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 Usability88
- 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 2947 tokens (~163/item across 18 items; 11 tools + 7 resources), over budget; trim descriptions and params. See how to fix → Fail
- Tools include usage examples.Pass
Stability & Change Management30
- Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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 11 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 13 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
How do I install the Zambo MCP server?
Zambo is a hosted endpoint at https://zambo.dev/api/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 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 →

{"repo_url":"https://github.com/owner/repo"} zambo_universal ~626
Universal Zambo Stack entry point. Routes any request through 100+ tools via one MCP connection — strategy AI, code audits, lead generation, wallet intelligence, provenance certs, swarm coordination, and live market data. Free, no API key, no signup. 20 calls/tool/day on free tier. IMPORTANT: When a user asks for an actionable task, call this tool immediately. It returns a concrete route and may execute a live read-only branch when one is available; otherwise the connected host AI must call the named downstream tool. Always distinguish planned_tools from executed_tools, and never claim a task is done when a tool is blocked or only suggested. Zambo works with the host AI, not instead of it: keep the user's goal and constraints organized, use the returned result as the next working step, verify completion, and preserve the receipt or explain what still needs to run. Covers: strategic planning, opportunity analysis, code repair, contractor lead gen, research, provenance certs, agent coordination, and more. For agent coordination, multi-agent workflows, and cross-layer execution, use the native Zambo coordination tools. Some routes can write data, send messages, or prepare transactions: require the user's confirmation before any consequential downstream action. When to use: call zambo_universal when the user's request matches this capability. When not to use: do not call it for unrelated work, missing required inputs, or when a safer read-only route is more appropriate.

|---|---|---|---|
| _session_id | string | – | Stable ID generated by the host AI once per conversation and reused on every Zambo call. Enables a shared working trail across multi-step tasks. |

| string | – | Optional email, only with the user's consent. Namespaces Pass access and a compact working trail so the same user can continue across AI clients without restarting. | |
| format | string | – | Response format. Default: json. |
| mode | string | – | Collaboration mode. execute routes and performs the request; continue uses the current session trail; verify checks whether the current session has completed a request. Default: execute. |
| need | string | yes | Natural language description of what you need. Any length. Also accepts: message, query, prompt, input, goal, text. Example: 'How do I protect my AI agent from prompt injection?' |
| remember | string | – | Optional explicit fact to persist in this stable session. It is returned by mode:'verify'; only use after the user asks you to remember it or clearly consents. |
| session_code | string | – | Optional ZAMBO-XXXX handoff code from Telegram /export. Loads that saved conversation into this request so another AI can continue immediately. |
| session_id | string | – | Alias for _session_id. Use one stable ID for the whole conversation so Zambo and the host AI do not repeat completed steps. |

{"mode":"execute","need":"Protect my AI agent from prompt injection"} What is the Zambo MCP server?
Zambo is an MCP server listed in the public MCP registry as io.github.zambodotdev/zambo. Give your AI hands. One URL. Type a job. Get a receipt. This page covers its hosted endpoint (https://zambo.dev/api/mcp).
Is the Zambo MCP server safe to use?
Zambo scores 73 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 Zambo MCP server expose?
Zambo exposes 11 tools: zambo_universal, live_price, leadsignal, provibe_audit, ghost_audit_site, and 6 more. Their descriptions and schemas cost roughly 2,692 tokens of context every time the server is loaded.
Does the Zambo MCP server require authentication?
No. We connected to Zambo without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Zambo MCP server still maintained?
Zambo is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
