Common questions

Is Spectra MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 9 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

MetaVault MCP

Multi-protocol yield intelligence for AI agents — covering Spectra Finance, Pendle, and Morpho via the Model Context Protocol.

55 tools · 3 protocols · 10+ chains · read-only · open emergence architecture · calibration intelligence · on-chain Curve quoting · Pendle logit AMM modeling · ERC-4626 health checks · yield curve term structure · historical eth_getLogs · full Pendle protocol parity (15 tools) · cross-protocol position map · cross-protocol Spectra↔Pendle comparison · veSPECTRA + vePENDLE governance · Pendle historical time-series · Morpho supply-side visibility with supplier cascade modeling · Morpho user positions & historical rates · Merkl campaign APR + expiry integration · entry path awareness · prescriptive observation boundaries · curator risk monitoring · withdrawal stress testing · rollover planning · multi-vault portfolio aggregation · pool expiry monitoring · zero web3 library dependencies

What This Does

Any AI agent (Claude, GPT, open-source) that supports MCP can query Spectra, Pendle, and Morpho in a unified interface to:

  • Discover the best fixed-rate yield opportunities across 10 chains simultaneously
  • Analyze specific PT/YT positions with full data (APY, TVL, liquidity, prices)
  • Calculate leveraged looping strategies (Spectra PT + Morpho collateral) with auto-detected borrow rates
  • Compare fixed vs. variable yields to make informed decisions
  • Track wallet portfolios across all Spectra positions (PT, YT, LP) with Merkl reward integration for complete PnL
  • Surface external Merkl campaign APR alongside pool and market data for both Spectra and Pendle
  • Monitor pool trading volume, individual transaction activity, and cross-pool address scanning
  • Quote PT trades with on-chain Curve get_dy() for exact output, falling back to math estimates
  • Simulate portfolio state after a hypothetical trade (BEFORE / TRADE / AFTER with deltas)
  • Scan all chains for capital-aware opportunities with price impact, effective APY, and Morpho looping analysis
  • Detect YT arbitrage opportunities where IBT APR diverges from YT implied rate
  • Compute real veSPECTRA boost multipliers per-pool using live on-chain data from Base, and vePENDLE voting power from Ethereum mainnet (with sPENDLE transition awareness)
  • Map your full cross-protocol position in one call — Spectra + Pendle + Morpho + governance (veSPECTRA + vePENDLE), with contradiction detection (unused boost, lending vs fixed rate spreads, concentration, looper detection, expiring positions across protocols)
  • Assess entry path complexity — automatically flags exotic underlyings, sw-wrapper hops, and mainnet gas friction so agents know the real cost of reaching advertised yields
  • Discover live MetaVaults across all chains — curator info, TVL, APY, positions, epoch history
  • Model MetaVault "double loop" strategies for curators — vault compounding + Morpho leverage with curator economics, auto-populated from live API data or manual parameters
  • Monitor MetaVault operational health — curator dashboard with vault allocation per position, depositor flows, fee revenue, bridge activity, and actionable alerts
  • Query Morpho lending markets for PT collateral opportunities, identify who supplies the lending liquidity, and discover vault allocations across markets
  • Query protocol stats, tokenomics, and governance data
  • Compare Spectra vs Pendle yield opportunities side-by-side with maturity-aware matching on overlapping chains
  • Scan both Spectra and Pendle for the best curator opportunities with capital-aware sizing and cross-protocol match tagging
  • Browse Pendle markets across all Pendle-supported chains (including Pendle-only chains like Mantle, Berachain, HyperEVM, Corn)
  • Analyze Pendle markets in full depth — market details, portfolio tracking, trade quoting, trade simulation, looping strategies, YT arbitrage, expiry monitoring, yield curves, capacity analysis, and protocol-wide stats (full parity with Spectra tools)
  • Assess pool depth with multi-size capacity curves — quote PT trades at geometric capital tiers ($1K→$1M) to find the sweet spot and exhaustion point on both Spectra and Pendle
  • Verify IBT health before deploying — on-chain ERC-4626 conversion rate, APR sustainability (organic vs incentive), pool balance, protocol recognition, liquidity
  • Visualize yield curves (term structure) for any underlying across all chains — all maturities sorted chronologically with curve shape analysis
  • Recover historical on-chain pool activity via eth_getLogs when API data has aged out — with dynamic RPC URL support for any chain
  • Monitor curator Morpho position health — liquidation distance, borrow rate drift, health factors across all chains
  • Stress-test MetaVault withdrawal scenarios — liquidity waterfall analysis (idle → maturing → LP removal → PT sale) with market stress simulation
  • Plan position rollovers for expiring MetaVault positions — cross-protocol candidate ranking with entry impact, yield gap, and overlap windows
  • Aggregate multi-vault curator portfolios — total AUM, blended APY, fee revenue projection, concentration analysis by underlying/chain
  • Monitor pool expiry across all chains with readiness assessment — successor pool detection, gauge status from governance API, and operator checklist (deploy pool / submit gauge / ready for migration)
  • Learn protocol mechanics on-demand via mv_get_protocol_context (PT/YT identity, Router batching, deposit paths, glossary, fees & costs, workflow routing, externalPositions registry)
  • Surface protocol YT fees (Spectra 3%, Pendle 5%) and Merkl campaign eligibility (POOL vs HOLD) directly in tool output so agents apply them without external lookups

The agent doesn't need to understand PT/YT mechanics -- it just calls spectra_scan_opportunities or pendle_scan_opportunities with its capital size and gets ranked, actionable data. For cross-protocol comparison, mv_scan_curator_opportunities ranks both protocols together. If it needs to understand *why* something works that way, it calls mv_get_protocol_context.

Open Emergence Architecture

The server is designed so that AI agents can discover novel strategies without being taught specific strategies. Instead of hard-coding strategy identification logic, the system teaches protocol mechanics at three layers — and lets the agent compose building blocks into its own analysis.

The Three Layers
Layer 1: Protocol Context (mv_get_protocol_context tool + resources)

→ Teaches the "physics" of the protocol: PT/YT identity, Router batching, minting → Available as a callable tool (on-demand) and as MCP resources → Static knowledge — what CAN happen, not what IS happening

Layer 2: Tool Descriptions (every tool's description string) → Teaches domain-specific mechanics relevant to that tool's data → Cross-reference nudges: "use spectra_get_portfolio to check actual holdings" → Uses "could be" language, not "is" — preserves ambiguity where it exists → Calls out hidden mechanics that could mislead (e.g., AMM_ADD_LIQUIDITY can mint YT)

Layer 3: Structured Output Hints (computed at runtime in tool output) → Position Shape analysis in portfolio: balance ratios (e.g., "YT/PT 4:1") → Portfolio Signals: concentration, maturity alerts, strategy shape across positions → Volume Signals: volume/liquidity ratio, buy/sell skew, trend detection → Morpho Market Hints: capacity warnings, utilization alerts, spread analysis, reward incentives → Morpho Supply-Side Analysis: supplier identification (vault/EOA/looper), concentration metrics, supply gap warnings — surfaces where lending liquidity comes from and whether it's sufficient → Competing Interpretation Branches (A/B/C) in activity analysis per-address: multiple explanations for the same observable pattern, presented with equal weight. The agent must bring external evidence to collapse branches — the tension IS the info. → Statistical confidence boundaries: small-N cycle repetitions (≤5) flagged as insufficient for extrapolation, preventing false pattern-matching → Flow Accounting with competing hypotheses: YT-only, PT-only, fully exited positions each get multiple explanations that predict different future behavior → Address isolation mode: cycle detection, flow accounting, contract/EOA detection, pool impact warnings, gas estimates, pool context → Capital-aware warnings: short maturity, low liquidity, negative effective APY → Yield Dimensions in scan output: fixed, variable, LP, looping side-by-side → Strategy Tension: competing PT looping vs YT accumulation on same pool → On-chain quote source indicators: "(on-chain Curve get_dy)" vs "(estimated)" → Yield composition: IBT APR breakdown (organic base vs external incentives) in scans and quotes → Incentive sustainability: flags when >50% of IBT APR or LP APY comes from incentives, shows "organic only" APY so agents can assess yield durability without incentive assumptions → Pool reserves: IBT/PT amounts with ratio for AMM imbalance analysis → Merkl campaign APR: external incentive programs (e.g., KAT rewards) shown per-pool/market with double-counting avoidance (skips campaigns whose reward tokens are already displayed) → Merkl campaign eligibility: action type (POOL/HOLD) always shown, with explicit "[LP only — not for YT/PT holders]" flag on POOL campaigns to prevent misattribution → Protocol YT fees: Spectra 3% and Pendle 5% shown in every pool/market detail output so agents apply them to yield calculations without needing external lookups → Points multipliers: external programs (Drops, InfiniFi, Firelight) with amounts → "Could be" / "at current rates" language: preserves ambiguity in ranked output → Makes key signals SALIENT without prescribing interpretation

Layer 4: Observation Coverage (quantifies blind spots in tool output) → Value coverage: what % of an address's position is explained by observable activity. Low coverage means most behavior is invisible (direct mints, transfers, cross-chain). → Temporal coverage: active days vs dark periods with no observable events. Longest gap duration surfaced so the agent can reason about invisible activity. → Data source coverage: which of 5 available sources were consulted vs not. Explicitly lists what is invisible to the current analysis. → Activity diversity: single-type activity flagged as highest-ambiguity pattern. → Boundary marker: "Position sizing should assume this analysis is incomplete, not comprehensive." — a structural admission of domain-of-validity limits. → Coverage metrics bound ALL interpretations above them. High-confidence strategy assessment + low observation coverage = false confidence. The coverage section forces the agent to size its conviction to what it actually observed.

Design Principles
  • Teach mechanics, not conclusions. The server explains that AMM_ADD_LIQUIDITY *could be* a mint+LP batch operation — it doesn't conclude "this user is accumulating YT."
  • Present competing interpretations, not single narratives. Activity analysis outputs multiple interpretation branches (A/B/C) that predict different future behavior. The agent must bring external evidence to collapse them. This friction surface prevents premature pattern-matching — the most common failure mode in wallet strategy analysis.
  • Flag statistical insufficiency. Small repetition counts (≤5 cycle detections) are explicitly flagged as insufficient for extrapolation. The agent cannot treat N=3 as a confirmed pattern.
  • Every tool cross-references at least one other tool. This creates analytical workflows without dictating them. The agent learns to chec
