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 Security83
- 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 is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability74
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 2351 tokens (~111/item across 21 items; 21 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 Coverage87
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 56% of tool parameters carry a description.Partial
- Structured output schemas are declared (48% 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 21 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 22 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
How do I install the three.ws pump.fun MCP server?
three.ws pump.fun MCP is a hosted endpoint at https://three.ws/api/pump-fun-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_bonding_curve Bonding Curve ~167
Bonding curve analysis: real reserves, virtual reserves, and graduation progress (on-chain). Pre-graduation only: these reserves come from the pump program bonding-curve account, not from a PumpSwap pool. Pump renamed the quote-side fields on-chain (real_sol_reserves -> real_quote_reserves, virtual_sol_reserves -> virtual_quote_reserves) once a non-SOL quote asset became possible; the response keys below keep their original names and are still denominated in SOL, because the curve quote_mint is the SOL default on every coin created to date. Once complete=true the curve is retired and pricing moves to the PumpSwap pool, so use pumpfun_quote_swap from that point on.
| Name | Type | Req | Description |

| mint | string | yes | – |
| network | string | – | – |
| Name | Type | Req | Description |

| solReserves | string | yes | Real quote reserves in SOL (4-decimal string). On-chain field: real_quote_reserves. |
| tokenReserves | string | yes | Real token reserves (raw base units) |
| virtualSolReserves | string | yes | Virtual quote reserves (lamports). On-chain field: virtual_quote_reserves (u64). Spot price = virtual_quote_reserves / virtual_token_reserves. Distinct from the identically-named PumpSwap Pool.virtua… |
| virtualTokenReserves | string | yes | Virtual token reserves (raw base units) |

get_coin_intel Coin Intel ~147
Full Coin Intelligence snapshot for a pump.fun mint. Returns every signal the engine recorded during the observation window: bundle vs organic verdict, bubblemaps-style cluster connectivity, smart-money presence (with wallet labels and win-rates), dev behaviour, category/classification, news-meme detection with the matching headline, risk flags, and a 0–100 quality score. Also returns the outcome if the coin is old enough to be labeled (graduated/rugged/ATH multiple). This is the single highest-signal read for a trade decision — call this before entering any position.

get_oracle_conviction Oracle Conviction ~199
Oracle conviction score for a pump.fun mint: the fused 0-100 score the Oracle engine produces by combining four intelligence pillars: pedigree (who bought it), structure (organic vs bundle, holder concentration, bubblemaps connectivity), narrative (category, meme virality, news hook), and momentum (timing, velocity). Returns the tier (prime ≥86 / strong ≥72 / lean ≥54 / watch ≥36 / avoid), the per-pillar breakdown, the natural-language reasons that drove the score, the full "who's in" trader roster with reputation labels and win-rates, and the narrative read (category, virality, tags). Call this when you need the highest-confidence trade signal; it synthesises everything get_coin_intel exposes into one actionable score. Pairs with get_coin_intel for raw signals.

Is the three.ws pump.fun MCP server safe to use?
three.ws pump.fun MCP scores 86 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 three.ws pump.fun MCP server expose?
three.ws pump.fun MCP exposes 21 tools: get_token_details, get_bonding_curve, get_token_trades, get_trending_tokens, get_new_tokens, and 16 more. Their descriptions and schemas cost roughly 1,921 tokens of context every time the server is loaded.
Does the three.ws pump.fun MCP server require authentication?
No. We connected to three.ws pump.fun MCP without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the three.ws pump.fun MCP server still maintained?
three.ws pump.fun MCP 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.
